Sabine Hossenfelder investigates life's big questions through the lens of physics, particularly Einstein's theory of special relativity. She highlights the relativity of simultaneity, which states that the notion of "now" is subjective and dependent on the observer. This leads to the block universe concept, where past, present, and future all exist simultaneously, making the past just as real as the present.
Hossenfelder also emphasizes that the fundamental laws of nature preserve information rather than destroy it. Although information about a deceased person disperses, it remains an integral part of the universe. This idea of timeless existence, derived from the study of fundamental physics, offers profound spiritual insights that can be difficult to internalize in our everyday lives. As a result, Hossenfelder encourages people to trust the scientific method and accept the profound implications of these discoveries, which may reshape our understanding of life and existence.
As a physicist, Hossenfelder trusts the knowledge gained through the scientific method and acknowledges the challenge of integrating these deep insights into our daily experiences. By contemplating these profound concepts, we can potentially expand our understanding of reality and our place within it.

What do you think of this explanation of time?
A bigger Question is not related to if our essence (information) that makes our personality transcend time, but Why did this specific compound of information came into being united to conform us in a specific time.
I think she's fantastic. It's important to relate what we learn from science to how we feel and experience the world in a more subjective way. There is sometimes a bit of distant between science and spiritual things, but in a way they will always be connected. Just because their ideas sometimes get misused by people who can communicate with the dead for $30, doesn't mean everything to do with spirituality is necessarily false.
I'd be interested to read her book I think.
@@pepevelez4742 I don't know if I've understood your question, so apologies if not. But maybe it's to do with observer bias.
So, the fact that we have become conscious would make us think that it seems strange that it happened now. But if you take our coming into existence as a fact, then it was going to happen at some point, and it was always going to feel like it was strangely specific if it happened now, or in a thousand years, or a billion years. The time of when it happened isn't important if you're to state that it was definitely going to happen, and given that it has, you can say it was definitely going to happen in this universe.
Since time is of physical significance (relativity theory), then it must be physical. But it can't be involved in the afterlife, since the afterlife, should it exist, is nonphysical. If time is nonphysical, then it can't be involved in the physical world because time would be in contradiction with the physical. So, time has no involvement in the afterlife. The question of afterlife is unrelated to time. We must ask the following questions instead. (a) does the nonphysical exist?, (b) If yes, is there anything nonphysical in our consciousness (the soul)? (c) if yes, our soul is in contradiction with the physical world, so the nonphysical can't be involved in our consciousness. There is no afterlife, then.

@@andrewfrank7222 We are all unique. Find me two identical persons throughout eternity
@@bitkurd No two snowflakes are identical either. But their stories and circumstances are exactly the same in the grand scheme of things.
I lost my father to dementia on August 20th 2022. He was several months shy of his 100th birthday. He died in my arms at hospital. I was his full-time carer for 12 years. I had lived with him all my life. During his life, I never heard my father speak of anything spiritual, no mention of Heaven, not until his final days. During the last four days of his month-long stay at hospital, I stayed with him in his room 24/7, never leaving his side. I kept a journal, detailing his final hours. Here are my notes from that journal which I used for my eulogy at his funeral:
His voice is veiled as he asks me to help him to stand up, he wants to go home.
"Help me stand up" he says, "I want to go home. My mother will be wondering where I am!"
Even if I could help him to stand up, he is so physically weak and depleted now, that I think we both would fall.
Late yesterday afternoon, when I was about to leave him for the day, I asked him if he minded that I should go, assuring him as I do every day that I will see him again in the morning.
"If I am here ..." he replies.
"Where else would you be?" I ask him.
"In Heaven!"
How his broken voice it breaks me and so, I arrange with hospital staff for me to stay with him the night. Several hours earlier he had told me that there were people gathering about us in his room. Looking to either side of me, firstly over my left shoulder and then to my right, they who were there not for me but only him were dressed in white.
"Do you recognize any of them?" I ask him.
He raises a boney finger and replies: "Just one!"
I ask him who the person is that he recognises and he tells me that it is himself.
"What age are you?" I ask him.
"I am 15!"
At the time of writing this, I have been by his side a full thirty-four and a half hours.
Inasmuch does his mind meander, I am never not so knowing of what he means.
"Lift me up, I want to go home!" he says over and over: "I want to go home!"
Holding his hand, I tell him that although I cannot lift him up physically, I can at least lift him up toward Spirit, and I place my other hand at where his heart is and say to him: "Home is where your heart is! If you live within the home that is your heart, you will always have Love; you will always know Love: God's Love!"
"I want to go home!"
Massaging his chest gently in a clockwise rotation, because the motion of Life is always forward even after Death, yet without actually lifting my hand from his ever weakening heart, I lean forward and whisper into his ear that he can go.
"Go home! You do not have to stay, just know that I love you!"
"And I love you!"
He is even weaker now but not yet gone, and I do not think that I have ever known of a moment so innocent as this, the lingering of a Life as do the Guardians of Love they prepare His way.
His doctor visits with me. She is concerned for me that I have stayed the night, telling me I need to look after myself.
Squeezing his hand a little tighter in mine I look at her and say: "I Am"
Another day passes during whose time he is bathed twice in his bed, first in the morning and then again at night: Bed Bath Lite. The ritual of cleansing a rite of passage now, water, glycerin, gels and fragrant oils, they do not soil the sheets but soothe his skin, tissue-paper thin.
He breathes in and breathes out ever more purposefully on the exhale, and I copy the sequence of sighs sorrowfully, that none too cold each pant becomes, nothing so irregular, not just yet. I would bet myself he would live another year but for my fear the end is near we both do know it, and I think to myself how stealthily the dusk does creep before the breaking of each new dawn a waking day, how we live to die and die to live reborn.
With his cheek resting softly upon the pillow I lay my head at his side. He places his hand on my head and touches my hair. and I want more than anything for him to keep it there.
As his breathing becomes more shallow I chant: "Everything I am is of you; all my love is yours!" "Everything I am is of you; all my love is yours!" but then to add: "If you take my heart with you when you go, my love will be with you and forever more, because of the love I give to you are you a part, two soles, one heart!"
I dim the light to dull the play of shadows upon his features that I see only myself in him now.
And then, at the eleventh hour of my stay this day he takes his last breath and quietly slips away, into the silent land where there is only Love and Time it has no borders, bound not by night neither lit by day, only Love! Love has sped him away!

Just watched my grandmother slowly pass away in hospice, she passed on December 23 at 1:15 am, this was also the exact same time my brother was born on this day. I hope she is still somewhere out in the universe she was such a good soul. I don’t think I’ve been more afraid of death than after seeing my grandmother in hospice
Ever woke up from a dream and sworn blind it was real? Your Grandmother will never lose touch with you, check out a poem called 'Death Is Nothing At All' by Henry Scott-Holland.
Take care!
🕊
She's dead, sorry, however you do have your memories of her, and that is something.
Interesting........ my son was born soon after my grandfather died!
My poor mom was so sad and so happy in one day!
She's still out there in the Heavens in the Universe.
If Alice and her friend made eye contact are they making eye contact at the same time?
I feel like in a way, space time itself is what truly defines the “uniqueness” of an individual. All of us, a product of our environments within all things surrounding us, all things themselves with the potential of influencing us to make specific choices and build certain habits. Something I like to say is that “your perspective is your definition”, meaning your perspective is your reality, it’s what defines your position in space and time. No one else on this planet is within the exact area of space you take up within space time. No one else on this planet has walked the exact same steps you’ve walked in life, and no one has processed those exact thoughts you processed within each specific moment.
As Einstein wrote in a letter to the family of his close friend Michel Besso after his death:
"Now he has departed from this strange world a little ahead of me. That means nothing. For us believing physicists, the distinction between past, present, and future only has the meaning of an illusion, though a persistent one."
Einstein himself died a month after.
Yes, I read about that. He wrote a letter to a widow of a friend, and basically said: Your husband is not truly gone. He is just on the other side of the hill, you can't see him but he is there". He meant that time is like space in the sense that what we consider "now" is not the same "now" for everyone.
@@carloshgrant or it was just a comforting letter that didn't mean much
Into the eternal void.
Well "NOW" I'm really confused!@@carloshgrant
@@TheGuitarReb which one? the "now" to me or to the gigazillion matter in the universe?
I love this explanation. My husband lost his father in his early 20's.
When I was pregnant, I started doing research on my family and my husband's family because neither of us knew much. I built our family tree, scoured over census archives, old newspapers, obituaries, and found photos! One photo was of my husband's 3rd great grandfather, he was wearing his wife's bonnet as they both stood in a tree smiling from ear to ear. They were on a picnic and climbed a tree. They were having fun. I immediately started laughing and crying at the same time. My husband had the same personality as this man he never even knew about. It was a parallel moment to our life and love...except our picture was taken on a rock at the beach. It made me think maybe we aren't so different from our ancestors, despite all the time that has passed and living in completely different eras. That made me feel closer to all of my ancestors. We are them. They are us. All existing together if you think of it. Like a chain.
What a beautiful way to say something so deep and profound!
I can tell you what happens when we die. If we have lived good lives we reincarnate here and if the opposite is true we fall to Hell. All the blessings that we receive this life have been earned during our past lives. That is exactly why some or us are born rich and healthy and others poor and ill. Makes sense, no?...............Falun Dafa explains many of life's mysteries, including time.
Families many times reincarnate together, meaning brother and sister today may have been husband and wife last lifetime.......................falun dafa
@@jeffforsythe9514LOL. If that were true, then our entire existence would be waiting until we are sent to hell. This should be obvious to anyone who spent any time thinking about it: you keep getting reincarnated until eventually you are reincarnated into a circumstance where the influences on you to do evil are greater than the influences on you to do good. So you choose wrongly and now go to hell for all eternity. Quite an awful belief system there. 🙄
In fact, the belief in hell at all for any religion is unjustifiable. (Christianity didn’t add it until around 500 AD.) it’s just another way that humans try to elevate themselves over others rather than trying to lift each other up.
@@jeffforsythe9514 prove it
this made me think of a scenario where if im on a planet lights years away, trying to find myself on earth with a super hyper-advanced telescope, I might be able to see my younger self and my late grandfather who may still be alive. idk how scientifically correct this thought is but thinking about this brought tears to my eyes.
❤🙏🏽
Being 1000+ light years away with an advanced enough telescope and seeing Earth and civilizations from 1000+ years ago in real time would be very interesting. If only we could transport ourselves like that without an enormous amount of time being lost simultaneously.
your thinking is absolutely correct! there might be aliens watching us from billions of light years away from a planet and probably watching dinosaurs
I found myself having this thought, looking up at the sky on new years and thinking about my mum. On some planet, they're still....here. 💔
This is a reasonable thought given the kind of physics she is explaining here. But 90% of the comments here are twisting what she is saying into justifying a 2nd life after physical death.
''But as a physicist, I trust the process of knowledge discovery that comes from using the scientific method and so I take this seriously'' ❤🙌
What would you like to know about the universe? I can answer your questions. Then.. you can validate them over time.
Well it is that very process which provided the tools that you used to write that comment along with every piece of technology you use in the world today. If there is anything in this world that has proved itself worthy of trust it is that.
Es indeed
I respect Sabine, not because she validates some preconceived notion of an afterlife, but because she is honest and open about taking physics wherever it leads, regardless of how mysterious, even "unscientific," it might seem.
You do realize that she doesn't mean life after death as in a typical way in fact I would even say that even if the information that makes up you still exist after your death that doesn't mean that it's alive as you are
@@LungaMasilela assuming that no information is ever lost or destroyed; it is not inconceivable that it could be entangled or part of some entity of which we are not able to know.
I give you the analogy of what happens when something ( or a person) falls into a black hole. Once it traverses the event horizon, that person or object is as good as dead to us, because the fate and only possible future for that person is the singularity with which it will come together in some way. So we cannot draw any conclusions about its condition because the rules of physics no longer apply once inside…. Which means that we cannot draw any conclusions about that information within; which also means that anything is possible beyond our imagination or definition of what life is!
@@Slo-ryde You're drawing conclusions Dr. Hossenfelder never made about death. We are one giant quantum system, and all of our atoms have their own wave functions and particle wave duality. When you die, the (entangled) atoms return to the earth and will be dispersed throughout the universe in a few billion years when our Sun goes supernova. There may come a time when a future species learns how to regain access to the information that comprised "you" but the spirituality Dr. Hossenfelder is referring to is about relativity, biology and spacetime. She didn't touch on entropy, which is an extremely important component of this discussion but I'll leave that alone.
Dr. Hossenfelder follows the scientific method to the letter. She regularly questions scientists drawing conclusions that aren't scientific from data, and you'd know that if you watched her channel. She is largely against Multiverse Hypotheses and String Theory because she views them as unscientific.
... she might be better if she looked at Leonard Susskind work. 🤔😉
I am really happy to see someone who does not blatantly ignore the notion of life after death just because it does not fulfill the scientific approach. We need more people like her to encourage young scientic to think rationally and outside the box
If you think she in any way talked about "life after death" you completely misunderstood this talk. What she said is that past moments keep existing in some form, that is not retrievable for us. This is NOT about keeping existing and still generating new moments, what life after death in the religious sense usually means.
@@thomasseichter5670 I think I failed to explain my point clearly. As an academic myself, I always tell my students that science is a framework of tools and methods that help us understand our world. But science is constantly in the process of improving itself. We should not objectively look into the phenomenon or religion practice but should train ourselves in having an open mindset and think outside the box. The question of life after dead cannot be answered by science because we do not have empirical data but that doesn't mean that we can refute that life force seizes to exist.
@@batosato I fully agree with what you said on the approach we should take when we handle topics like these. And I apologize for misunderstanding your point. We have to be open to the possibilities. As long as we are not able to explore these claims the most honest answer here is "we don't know"
However my problem with religions is they are not honest because they claim to know. And not only know "that" but even specifics about "what" and "how". And claiming to know what you can't possibility know is not thinking out of the box, this is lying!
But I keep to my point, that Sabine is not talking about "life after death" in any form that resembles the notion of the what the big religions claim it is in this video.
@thomasseichter5670 we don't know is a very good statement which I barely hear, i only heard it once from a renowned physicist but at the same time I heard other renowned physicist constantly dismissing this point some of them in a very aggressive manner. We should continue to think , rethink and explore and admit that we do not have the knowledge of everything.
@@thomasseichter5670 think you both are right, bat. and you. Of course she's in fulfilling the scientific approach, that's her philosophy. She makes a statement to the nature of spacetime, the 'block-universe' and to determinism, not to 'life after death'. On the other hand, she leaves enough place, and I think there is place, for own conclusions and ideas, about what it means for you. She calls it 'ascientific, but not wrong'. Quite a human attitude. All to read in her book.
Wow! That was the best explanation. I struggled with this concept but she made it so clear so simply. Thank you.
Something so complex, beautifully explained in the simplest manner
This was very scientifically informative and spiritually comforting. Two things can be true at the same time.
Your last sentence is spoken like a true quantum physicist
If the history of science is an indication, the vastness of the unknown might never noticeably shrink; as a metaphor, there's continuation on the seemingly magical path of discovery, where every answer likes to bring in three new questions. Perhaps more comforting still, it has been said that all worlds that are populated by at least one existentialist also have metaphysical meaning.
Not both true at the same time
Though, it's generaly preferable to try to aim towards what's more probable and plausible
Never die 👍🏼
I'm terrible at math, but I do love trying to visualize and wrap my head around physical concepts. Really interesting how our world, our reality is so so strange.

Lucky u can visualise things, while I have just blackness and my inner monologue.
It is not strange it just is, what is strange is although we live in this universe has we call it we don't consider that the possibilities of nature of existence are endless and are limited only by our ability to comprehend.
I attended a memorial service for a friend last week, where an unfamiliar individual delivered a speech. During his address, he expressed his hope for an existence beyond this life because he believed that "this certainly couldn't be it." In response, I shared my perspective: "This is it. Life's purpose is companionship, friendship, and love. But confusion and unhappiness arises when we lose sight of this fundamental purpose and expect more than that."
There's this quote I like:
“In death the many become one; in life the one become many.” - Rabindranath Tagore.
That love you mention is infinite and that love is God. GOD offers his infinite love to us which, if we accept means we will have eternal consciousness, as we are a part of God.
You must be fun at funerals.
No no no@@petehuckleberry5068
Sabine, your ability to break down the complex and esoteric ideas and concepts of science into plain-speak is sublime. You're a gift in our times!
I remember the first time I read the "Time Machine" by H.G. Wells, and the question struck me: if you travel into the future, are the people you left behind "dead?" After all, if you can travel "back" to see them, how can you say they are dead? And if you travel into the distant past, how can there still be people "there" if they are "dead?" If the past or future can be travelled to by someone with sufficiently advanced technology, then wouldn't that mean that someone always technically "exists," since you can always just return to the specific time/place where they are?
Wow. I’ve vaguely thought this before
It is about the past, present and future existing simultaneously. It is shown in the movie at the end when all 4 of the characters are standing in the same space but in different time.
@@IamtheHolyManwhat year is the movie ?

Perhaps when we die we ascend into a newborn self from the past but every time this happens, there are some changes in the timeline due to quantum uncertainty ?
Really fascinating. I remember as a very young child well before I had heard of Einstein or theories about special relativity, I believed that when someone or animal die they would somehow go back into everything. It was only when I became older and had been taught about Einstein’s ideas that suddenly I realised that I knew this already be it in a very much simpler form.
People tend to believe we came from nothing and return to nothing. This is not true. We came from everything and we return to everything. Energy cannot be created or destroyed. So you have always existed and will always exist.

The Time Traveler's Wife (the movie), is a great watch, if you haven't seen it.
Nobody cares or believes you. Stop trying to find validation through strangers on social media.
She is very nice and despite not knowing the afterlife research and knowing physics very well - she comes to the same conclusion that indeed time doesn't exist in the way that we observe here.
I'm a medical doctor and a scientist and I study consciousness on the side, and we observe that there is a continuation of consciousness after death. I encourage everyone to keep studying if they wish, the internet is full of publications and testimonies about the subject. Cheers!
What drivel.
But that consciousness that you observed happens few minutes after death declaration, which is not relevant to the main discussion about the after life. Sure after you kill a fish it may starts to move...etc. but we talking about what is after death, you will be gone for trillions infinite years with no return to this world, and you telling me few minutes when the body starts to die! Of course the brain might give it a final fight after body dies.
@@user-tw2xq5co1g the body is intricatley intertwined with consciousness, but they are not the same thing. Body is an animal, including the brain which you occupy like an avatar. The death state is not minutes, it's a much longer process in which your consciousness can dissocatie very slowly or be gone momentarily. You can bring the brain back to life several hours after decapitation, according to the latest research in pigs.
When you're gone - you're gone, and the experience is unlike any other. You no longer have the subconscious, the physical body is not there and you are point consciousness or you occupy what is called a light body. You are very intelligent and much more informed in that state, we call it the removal of the veil with the subconscious - you no longer have the limitations of the human mind. You can experience these non-dual states of consciousness with DMT in legal scenarios with highly trained professionals. I recommend to everyone who has strong beliefs either way - being an atheist or a religious believer - go and find out on your own.
@@user-tw2xq5co1g The entire problem has nothing to do with time. You can go and experience out-of-body states, I have not met a single person, whether they are atheists or religious, scientists or not, who have not re-evaluated their entire philosophy based on these experiences. We birth into forgetfulness to have a meaningful life. Have a good one!
@@DaGryboYour experience, memories, emotions etc are all carried in your brain these experiences can be altered permanently especially through diseases like Alzheimer's they are effectively gone the memories and experiences I don't understand why people desire existing forever nor a soul etc. Our ego ties us to these ideologies of eternity but eternity is no life worth living especially for our perceptions as a time based biological machine. We are the universe, these bodies are the result, consciousness is a wonderful illusion an advanced complexity of occurrences in patterns that follow the laws of physics. I respect your beliefs and I don't expect what I've said to have any weight against your beliefs as I have no desire to do such a thing. I merely wanted to show my beliefs, which is we are everything it's not consciousness not spiritual it's existence it's self the existence of matter and energy I'm still tied to my ego as it would ridiculous to not live your experience on this planet
You did a very well job of explaining relativity. Its an incredibly complicated topic to comprehend and I feel like my understanding of it is much higher after watching this single video, we need more people like her
I believe in people still existing everywhere all the time after death in a broad sense because I sometimes dream of being with someone in my sleep, without knowing beforehand of their passing or having known it was coming, so the thought that they are everywhere makes sense to me because our brains interpret information they receive, and somehow a person’s essence reached my mind like a frequency I could read. I just believe my brain interprets the information the best way it knows how. I think it’s possible to be everything anywhere all the time, like a drop of ink that fills a clear water up.
So Hitler, polpot, Mussolini, and every other lunatic is still alive according to you?
@@threestars2164 If you think about it, every human is capable of heroic, great and selfless acts as much as dreadful things, given the right circumstances and influences.
To deny they were human, even if they did deeds we call "inhuman" is maybe a bit short-sighted. So the way i look at this is they were part of the universe from our perspective and point in time and maybe they all transform into one being that is just there and not really judged? I mean if you look at how life was created, do you curse at the sun for enabling life on earth and eventually leading to mass murderers living here? Fauna or nature in general has vicious aspects as well. If we follow that logic, it probably won't make sense for whatever happens in the afterlife to judge by human standards.
@@threestars2164 This is, the only 'moment' that has ever existed. There is only, and has only ever been -this- one now; all of the rest passes through it according to your own observation of it.
If this is difficult for you to believe, I would challenge you to look up and try Neville Goddard's "Ladder Exercise" and prove it to yourself one way or the other.

Beautifully explained 🙏 brings solace to all those who have lost dear ones and torn between science vs spirituality 🙏
I've had a very difficult time understanding what relativity was my entire life. I probably still in all sense, have very little idea. I will say though that after watching this video, I feel now that I'm at least at a rudimentary level of understanding it. Before this video, I wouldn't even give myself that. She did a very good job of explaining through demonstration.

I was lost half way through, but the message I got was that some form of reality/life still exists after the physical body can no longer communicate via conventional means. I remember the saying that goes something like this: “What we do know is so insignificant to what we don’t know.”

Same. I think she glossed over the big reason we all came here. At one point after her train and two lights example she said something like, “and if we extrapolate this to it’s logical conclusion we can conclude afterlife.”
Yeah, uh, THAT’S the part I came here for. The “if we extrapolate this to its logical conclusion” part.
How does an understanding of relativity lead to simultaneity? Why does this idea about flashing lights lead physicists to believe all things exist at all times?
This could be due to the editor of this video, or the creator, and not so much the interviewee, but I take issue with this video. It’s a great example of how to provide a lot of information without actually saying anything.
The conservation of intofrmation is one of the big things that's bothered me about death for several years now. It runs contrary to everything I've learned about the laws of the universe. All their experiences, feelings, and thoughts can't just disappear because that's not how physics works. It's kind of reassuring hearing someone far, far smarter than I will ever be echoing similar thoughts
Hi. It was a relief to see Sabine discussing this issue without her usual ebullient enthusiasm. The topic is more metaphysics than physics, and Godel's incompleteness theorem must apply here. There are some things we can never know or prove. Cheers, P.R.
I'm having the sense that when we die we return to something much bigger and more important that our current lives. So important that our current lives don't really matter. Almost like finishing a good movie before coming back to the real world. Its quite comforting.
I think you mean we come back to the cosmos, from where we come from .
Imagine you are reborn as an alien in the other universe your life is looking 1000x times different than your previous life but you dont remember any of it
No matter what, we will always be recreated. If something occurred once, then the odds of it occurring again surely must be higher than the first time. So, given enough time we will all exist again.
You’re right on target but this life matters a whole lot because this is the only physical life….this is the beginning,the very bottom of the existential this the only time that you will experience time itself….everything that your human mind tries to reason will only be experienced in your current form of human….so enjoy every moment of it ✌️ and ❤️ to you.
@@marlonhernandez8367 Yes, I can't agree that this life doesn't matter. Why live it then? Ancient spiritual texts from India intuit that everything is happeniing at once. Time, space are just ideas. Our nervous system developed so that things do appear to happen in the past, present and future. Otherwise, we would be completely overwhelmed and couldn't function. The are deeper truths than just the "scientific method". Atoms are the throne of God from which everything is created.
I love Sabine! So cool to see her on another channel besides her own! She is SO intelligent and good at dumbing big things down for the rest of us and making it funny and engaging.
Recommend you her new book, she's talking about, if you don't know
@@Thomas-gk42 I'll have to check it out, thank you!
I ❤ Sabine too ❤️😍❤️ she's fantastic 😮
If you love her, you love to be bamboozled.
The rear and the front Flashlights are at the same distance of the external observer, only if the observer is standing still exactly at the median perpendicular line of the train, which halves it in two equal parts, and the train must necessarily be standing still at the railway as well. At the moment the train begins to move from left to right, the front flashlight begins to move farther apart of the observer, and the rear one closer. But Frau Doktor Hossenfelder, affirms exactly the contrary, i.e. that Alice, who is standing still at the window is moving closer to the front flashlight which is installed on the train. Which makes absolutely no sense.
That’s proof that she either has skipped basic physics classes, or she’s deliberately aiming to bamboozle the public.
Sabine is an amazing teacher!
I found her talk, and explanation, intriguing and on some more basic level, more understandable. Thank you for your time.
Sabine has a remarkable YT channel. She does tremendous videos explaining physics for everyone. She’s very good as this.
she's a breath of fresh air in a rather stagnant pool of irrational thinking.
The train example is super neat! I like how it makes me think about what now even is. Never thought about it before really.
Awesome. Great video, perhaps the best and simplest definition of our souls/lives.
"Every moment could be now for someone and that include moments in your past and it also includes all moments in your future".
I'm a Franciscan (who has also studied physics), and I have to say, this notion of timelessness, and the unknowability of whatever ordered it, sits very well with me.
Thank you Sabine. It’s absolutely important to question… to think even if it cannot come to a satisfactory conclusion.
Im really struggling with the sudden death of my dad right now. He was an astrophysist. This is really spirituality and scientifically comforting. I reallt appreciate the usage of "information" instead of "energy"
I got one problem with the train example: Alice should have the same experience because the initial speed of the left and the right lights in the Drive axis is the speed of the train, its like someone bounces a tennis ball from his hand towards the ceiling of a car in the space of a moving car, the ball will go down straits to his hand because the initial speed of him and the ball is the car speed.
I could sit and listen to Sabine talking all night long.. intellect and humanity combined.
I'm no physicist, but on the UA-cam spectrum of it, she's one of the best current teachers out there of physics for me.

Author Alan Lightman has written and spoken about the process by which material from the stars ended up as part of us, our physical bodies, as well as all life and most other substances in our world. She seems to then be describing the opposite, which is that when we die, all the material and information in our brains, the neurons, etc., are dispersed through physical processes into the Earth and eventually the universe. That's pretty profound to me, regardless of whether it's not quite as "exciting" as the prospect of life after death.

@@abhipsha5166 if the guy is right ... whats the problem with saying the same thing
Awareness of existence is inherently tied to one's perspective. When I am alive and experiencing life in the present, that constitutes my unique viewpoint. It's conceivable that others might exist in distant points of the past or the distant future, simultaneously undergoing their life experiences, but each person exists within their distinct timeframe. Thus, the essence of existence is fundamentally rooted in perspective.
Oh, Sabine, I adore your explanations of phenomena; had I had a teacher like you,, my doc would be in other than art history...
Thank you. That was a well-presented, sensible, and concise explanation of "now" according to Einstein.
Thank you for presenting this subject. Many years ago I was dealing with the death of a high school friend. I had no believe in afterlife however I began to question that assumption. I wondered if time could stop for the person that died ? Could we all end up on the other side of space-time at the same time (in a blink of an eye) ?
Just one hypothesis of many. I am grateful to share my thoughts.
can we live forever 😭
That was my thought too. The perception of "now", being that it cannot be perceived as simultaneous, is there a way that when we die, (almost like when you go under anesthesia, if you have before), we could wake up again in an instant? It might have been billions of years in "actual" time) for humans on Earth, (which I'm not even sure how to quantify an actual measure of time anymore, or that it even exists) but to us, almost no time passed at all?
@@saga-Same, I often asked myself whether we would just experience existence immediately after dying either in our newly former body (as in the Last Judgement) or as a newborn organism (a weaker form of reincarnation). Experiencing eternal oblivion wouldn't make it an oblivion in the first place (religious beliefs nothwistanding).
What? Well if he was buried he is still decomposing in time.
@@threestars2164 Their physical body decomposes. But to the dead person, there is no difference between a millisecond and a billion years. So what if there is some gigantic stellar consciousness/AI that exists very, very deep into the future of our universe, and it is able to reverse entropy and bring them back. Then from the point of view of the deceased, they will just pop back into existence immediately after dying.
Granted, this requires some massive leaps of faith about what is practically possible to do, but we live in a world where the inventions of the 21st century would appear as magic to someone from the 1600s. In a way it is not much of a stretch at all to expect something along these lines, or almost undoubtedly even crazier, considering the vast amounts of time involved.
I love the methodology used in this presentation to explain this question about our eternal existance. I personally have grown to appreciate the concept of time is a human one. One which does not apply to the death of our earthly bodies here. That is why it is important to remember family and pets and friends and all forms of life in this planet changes it's appearance and energy only.
i´ve never been into physics but damn, this is interesting. thanks for sharing your knowledge!
I lost someone I loved deeply some time ago. And after that I stated seeing death as a transformation. As our bodies decompose, our particles become part of other living beings, until one day we become part of the cosmos again. Just like Carl Sagan described it.

No, when we die, the body falls away and decays while the soul enters a fresh womb and is reborn here...........falun dafa
@@jeffforsythe9514 Please no, I don't want to do that birth crap again. It means I'd have to go to school again, I'd rather die.
So a particle from a shit Hitler once took is now part of a tree, meaning he is still alive?
That was fascinating. The only issue is that everyone seems to share the same "direction" of time, regardless of how "fast" it passes. So, if you get verification of death or a permanent event, it is always in the past and can't be undone.
This was a very quick and simplistic version of the explanation of relativistic time. She needed something quick and concise to demonstrate in a short video. Look up some more videos on the block universe for a deeper understanding. Yes, you as an individual may only experience time going one way and given the proximity and relative speed of everyone on earth it follows that we’re all basically going “forward” in time at essentially the same rate. But given enough distance from us and enough speed in the proper direction an observer may actually be traveling backward in “our” time while still traveling forward in theirs. That means that - while we may never be able to interact with it - the past is still equally as valid and real as the present and by extension the future.
@@bradarnold7834 What you said has never been demonstrated, and that would've been a major simple point for her to make if it were true. The arrow of time reversing is only hypothetical.
@@MrGriff305 The best explanation for why time appears to have a direction may be the fact that entropy always increases. Actually, this law of thermodynamics is a bit of a simplification: entropy increases the further you get away (in time) from a big-bang singularity _in either direction_.
That is to say, if we had a big-bang in our future rather than our past, we would observe that entropy always _decreases_. But in that case our memories would be about the future rather than the past... and those memories would look just like the ones we have in our universe. Perhaps there would be no way to tell the difference between that universe and our own... which would mean there isn't actually a meaningful way in which there is a direction to time.
(Though that said, the fact that a big-bang singularity exists at all is unexplained.)
@@CheCheDaWaff Thanks for the attempted explanation.
@@bradarnold7834 The problem is "Who is the observer?" Is it a human? No. End of story.
I think the diagram of the light flashes inside the train being seen at different times by Alice may be erroneous. They would be seen as arriving at Alice's position at different times by the observer outside the train, but Alice would see them simultaneously, since she is moving in their same frame, all inside the train. If the lights flashed simultaneously relative to themselves but arrived at different times relative to Alice, she would be able to detect her motion by noticing the non-simultaneity. She would not even need to know if they had flashed simultaneously to each other. She would note that the light behind her was red-shifted relative to the blue-shifted light in front of her, and thus able to detect she is in a state of motion. Whereas Relativity is based on the principle that you cannot detect your state of inertial motion inside a closed system. If the lights flashed simultaneously to each other, the wave fronts will reach Alice simultaneously. For them to be non-simultaneous in Alice's frame, they would need to be outside the train, attached to the ground.
So my life is recorded forever as an endless series of eternally living 'moments' in the block universe? Amazing. Wish I wasn't encoding this moment forever of sitting in front of a computer procrastinating some work.
Do the work then you can go back to recreating your moment of procrastinating. 😆
Procrastination won't happen if we understand there is sufferings in this life... So being born again & again is painfull; rather aiming for Sat Chit Ananda is the key.

Sabine is always a delight. I enjoy her passion for the truth and I find her explanations in this video fascinating. Bravo!
This is why I’ve always wondered how there can be a now when everything happens in the future and almost simultaneously becomes the past…
The fact that he remembers his grandmother means she is still alive in some sense. We know for a fact that our ancestors lived in the past for us to be here in the present, so they are still alive in the same sense. Experiencing firsthand the passage of time is like floating a raft down a winding river. You can't see very far behind or in front of you, but the path down the river continues both ways. Being here, conscious, is like a first-class ticket to the grand show, except you have to watch through a pinhole.
That's very different from being alive.

These are very much the same thoughts I have on it. We always exist somewhere, somewhen, even though in linear time most of the time we either arent yet born or are already dead.

"Present moment has no fundamental significance" but also "Present moment has the essential importance and is all that matters." According to things explained in video, past and future is also included in "now".
Knowledge is refreshing to come across on youtube. Great video
She explained this extremely well to a layman. Which is crazy because my dad just passed last year suddenly, and I have been thinking about all of these topics for years now, pondering the questions of our reality/existence/and universe, and how we perceive it and how it actually happens with our consciousness.
So far the most logical conclusion I can come up with is we either cease to exist, or the particles or information that made up our minds/consciousness will one day reform into another persons body and we live again without remembering but will keep going.
That’s the best way I can think of resurrecting to another body but with the same soul. I just fear that we become reborn into an animals body, and with how we treat cows and pigs.. maybe it’s luck of the draw and sometimes you come back as a human and other times as a chicken in a factory farm.
What you’ve said is somewhat similar to Hindu ideology on life after death . But rather than it being luck we believe that it’s our karma that defines whether we get moksha or have to go through all the life forms before we get a chance ti be human again.
I went through something like that after my mom died in November 2022. While looking for some hope that we might exist again after dying, I came up with something that is neither here nor there, although it sometimes freaks me out more than death. I came to the conclusion that not only we can never permanently die, but that from our perspective we will just keep on existing forever.
Sure, we will die, and billions of years will go on without us, but eventually there is no reason why nature wouldn't create us again. If something occurred once, then odds of it occurring again surely must be higher than the first time. Given enough time, we will be recreated, and since we would be dead, billions of years needed for us to be recreated will happen instantly. So, perpetual existence is our destiny forever. I can't believe I was thinking I would get away so easily by just dying and staying dead.
@@julius43461 I arrived at the same conclusion, but I think it goes crazier than that, the scope is not human life, earth, the solar system or our galaxy. Existence is fair game and I believe that the moment you die, billions of years will pass in an instant and you will start experiencing life as *something* else, somewhere in this or some other chaotic universe . And that I might fear more than death itself.
My father past suddenly a few years ago and I never really thought about the afterlife until that happened.
Alot of physicists seem to believe the past,present and future all exists at the same time so do you think its possible we could just live the same life over and over again?
@@julius43461 so do believe we will just live the same life over again?
The Block Universe is how I've been comforting myself about loves lost for years now. I can't remember where I read it but whatever it was said to think of time like the floors of a building being constantly built on top of one another, through which you are always climbing a staircase through the center of. Just because you're at a certain point on that staircase doesn't mean the other points on it don't exist. I don't know why but that resonated with me. Ever since, when the thought of those I've loved and lost comes to mind, I've imagined myself peaking in at them on whatever stair they're on, well and whole, and only out of sight because I've wandered off beyond the next corner.
I love this topic. Basicly everything that happened or will happen is happening right now all at once. Look up the "Andromeda Paradox" you will like it.
@@carloshgrantI was thinking the same thing. What she said about block universe that our past present and future all exist at the same time. So while I’m here, my past is still doing what had happened and so is my future self. I m not sure if I’m being understandable here but it’s crazy to think about it
@@anushamahalawat6163 This is going to sound crazy, but this is what Relativity of Simultaneity says: You and you wife are sitting on the couch. An alien in a really far away galaxy is standing on a park. Because you and your wife are both stationary to each other, you are both in the same "now" of that alien far away. If you get up from the couch and walk towards the the direction of the alien, your "now" will be in sync with the past of that alien, in relation to your wife who stayed still on the couch. If you walk away from the direction of the alien instead, your "now" will sync with the aliens future. Basicly what you consider to be happening right now is in the same of what the alien will be doing in it's future. Depending on how far the alien is, you could rewing or fast forward minutes days or even years into the alien's "now". This is just a extrapolation of what the theory says. There's actually a formula to calculate how far in time your "now" will differ from the alien's now". Look up this video on UA-cam: Brian Greene Alien on a bike.
@@carloshgrant sounds crazy!. I’ll check it out , thank you so much:)
I love the expanding of my mind through discussions like this. She is quite brilliant with a succinct way of expressing her knowledge. When my father passed away I kept wondering what had happened to him, where his consciousness went? And one day as clear as a bell I got the answer: He is everywhere.
I think if time is infine then we have lived infine times. Its too much coincidence to be here for the first and last time. Why do we exist in the PRESENT and not 100 or 100.000 or a centillion years ago? Why no one is talking about it?
I agree. Have you ever experienced general anesthesia? It's like turning a light off and back on. No dreams, no thoughts... nothing. I think we can all agree that before you or i were even born, that you really didn't exist. Everything that made up you body was else where along with the energy. In a sense, you experienced death before you were even born. You and I just lack the ability to remember it because we lacked a conscience. Like you said, technically speaking, we could be just dead now. This is why I believe we live more than one life. As to whether it is reliving your own, or others... That i do not know. There's a video out there called "Project Blue Book Alien Interview". I feel certain it is fake, but the way they describe "death", I feel is probably really the best way one could really describe it. @@dieterrosswag933
Nice to see Sabine on another channel ,awesome woman who knows her stuff ,i like her sarcasm too ,keep up the good work👍
Dr. Hossenfelder - this is the most enjoyable video I have watched of yours to date - especially your comments at the end. Einstein was supposedly quoted as saying that "we have forgotten something that the ancients knew". When one considers that the comparable distance within an atom of it's nucleus to its outer orbiting electrons is something akin to a BB in the middle of a baseball stadium, that the atom itself is mostly empty space, it is quite mindboggling to ponder what is holding it all together. The fact that the particles don't "fix" into place until observed has to call into question the relationship of mind and senses and the physical nature surrounding us. When you throw in "Space-Time", even more so. Thank you for sharing your intellect with us.

That's really beautiful. We're all a part of the universe for as long as it (one?) exists. Like "ashes to ashes" or "dust to dust"; We're always "particles to particles"
Yeah if you put it that way we're all basically the same we start the same and end the same, really puts into perspective how we should be more humble and care about things that truly matter
The point that I got out of this video is that it is not possible to destroy energy. And if life is anything, it is energy. Therefore, after "death", the energy of a human life still exists, but it is dispersed.
4:06 No, it is supposed to be the other way around. You would see that lights were not simultanious and Alice would see that they were.
From Alice´s point of view the lights are stationary relative to her. She ISN´T moving towards one of the sources, like Sabine claims.
The speed of light is the same in all inertial refference frames - Einstein´s principle of relativity. It has to be the same in Alice´s case as well, so she must see that the lights are simultanious.
It is crazy to see theoretical physicist like Sabine Hossenfelder make a mistake like that.
Brilliant and I truly appreciated Sabine's humbleness.
There is alot of talk about the light, but experiencing sound is pretty fun too. For example if the lighting strikes, you can coun't how far it hit by measuring seconds how long the time was from the flash. For me it's pretty exciting to guess how big of a bang there is coming.
The medical examiner explained everything brilliantly. Even though she used words and terms that not all of us would necessarily understand or know the meaning of, she did a really good job.
To an observer 10 light years away from us, if they could see the Earth and humans specifically, then they’d be able to see my mom. This was a beautiful explanation of what “now” means. It would be interesting to hear what Echkart Tolle would say about this. His premise is that you only live in the now. The present moment. But each persons’ now
is different and meaningless from what I got from this.
this is a lovely example, and it made me wonder further...if they look at the Earth and see me as a teen, I can't help but view that more as a kind of lightshow: they are witnessing something that "was" but not "is." It might look real, but it's a display. An interaction cannot happen. We can't interact with actors in a film, for example: those scenes were captured on film, and played later, they are static. For that reason, the "me" of that time is gone. Forever. "Teen me" is dead because I am the current version. Yes, someone might look at the Earth from "x" lightyears away and see the teen, and that might seem like a kind of "now," but they will know, just as we know, that they're just replaying a scene that no longer is "now." That "now" is gone. After all, they are unable to speak to her, only witness her. She's just a visual echo--beyond that echo, the true moment in which that echo originally occurred can never be recaptured (the interactions, words, thoughts, reactions, all of these had a chance, one chance, in less than a moment to be shaped. Every moment is a pretty radical moment of existence in that sense). If everyone's now is therefore different, I don't think that makes "now" meaningless; for me, realizing that my "now" is the present only for "me," is actually incredibly special because it's in these radical moments of now where I make decisions, interact, or not, and influence everything around me, creating ripples in the pond.
@@atrelanor4876 totally agree. Someone s past life is just a video that someone somewhere in the universe can watch ( assuming they have the technology to zoom in at individual level ) but because it is in the past the watcher cannot interact with it in the same way I can not interact with say someone s biography s video.
No, observer would not see your mom. Only the light reflected from earth surface which is not your mom, but an array of photons or waves if you will. Do not get too excited.
Thanks Sabine keep up this great work. And i feel that your on the verge of perhaps of some practicality out of a crazy messed up world but in the same sense a beautiful and wonderful world.
A bit of a different subject but I would argue that since time began or shortly after the ability to travel in time existed. Understanding the fundamentals of Einstein's theories lays this out for us to clearly see. Also in two methods. Motion and Gravity. With motion I firmly believe that mankind will eventually be able to propel himself in half light speed or greater where this can be exploited to our will. With Gravity, existing in one gravity field and travelling to a either lesser or greater field of gravity we would experience extreme time dilation per our perspective. The possibilities are very exciting.
I just watched an interview with Dr Sam Parnia. He is an ICU doctor who has basically studied when are you truly dead. He discovered that there is evidence that consciousness can “live” from minutes to hours after you heart stops beating and your brain waves are gone. His research is fascinating. It gets a bit technical but touches on near death experiences and consciousness.
I really want to start looking him up do you have any advice on where to start?
@@PrairieDogPitterPat - I saw him on a UA-cam channel called “Closer to Truth.” It appears that he has legitimate studies. I am wondering if this is the reason that you hear about those stories where people in the morgue “wake up” in hospitals?
If brain waves are gone there isn’t a time limit or minutes or hours. It’s just consciousness existing elsewhere.
Elsewhere is your Soul.@@mase8189
NDEs are incredibles and fascinating yes.
I think there's other forms of physics that we simply haven't discovered yet. If there are laws that govern physical reality then could it be possible there are other forms of physics governing other abstract relations in nature? For example, something like consciousness will never be explainable by "normal" physics because it's not quantifiable. We can't see it or measure it, but it's definitely real, there has to be some theory to explain abstract, formless entities in our reality.
Great talk, Sabine! Truly appreciate your highly practical view of existence. Humans like to ascribe human traits to everything, yet we are clearly pretty non-consequential - even to the point that when zillions of humans died and dispersed it will have zero effect on the underlying mechanics of whatever it is driving this whole thing (if, in fact, it actually exists...). For now, we have each other!
I would say just the opposite human beings as far as we know is the only ones who can alter the laws of nature maney someday the universe mabey that in itself will be our undoing
As a person who believes in science, I find this very useful to give me insights about existential questions that include sole sort of sprituality. All the answers given to humanity is mainly from religious background which doesn’t speak to my brain, but the moment she spoke, even though I’m not a physics freak, I was able to grasp her ideas and feel that it provided some comfort which religious people say they get from religion. Thank you 🙏🏼
So unless you perceive it as science and not spirituality you won't try to investigate. A narrow minded approach, most probably due to bias you have against the spiritual realm and the idea of God.
Yes unfortunately this is quite common due to religious trauma in childhood. I was that way for a very long time. I would shut down everything that wasn't 100 percent science based. I don't know if the person you're replying to has had issues like I did but you'll never understand unless you went through it yourself.

Wow.. Sabine you are 1 smart woman.. amazing you took the question from shaman to Einstein.. technically building it up.. n bringing out a mind blowing info abt the "NOW"
Bt for me Shaman is also right abt QM - Bcz you decoded the body in the spacetime.. n they have decoded w.r.t mind .. its a big topic..
Bt man would i love to share more than a cab ride with you .. such deep understanding of physics 👏
Very good, insightful discussion of Einstein's theory of relativity and how it has altered our view of time. However, I also think that quantum mechanics (QM) plays a significant role here. The problem with Einstein's block universe is that it's completely deterministic, and QM is not, or at least not in just 4 dimensions. I, for one, am a big fan of the Multiverse theory, in particular, Max Tegmark's Level 4 Multiverse, which according to him is the set of all logically consistent mathematical structures, or in other words, the collection of all conceivable universes free of logical paradoxes. And I also believe in spirits, by the way, but not quite in the way you describe them. I think dreams are windows into alternate universes and spirits can communicate with us through our dreams, including spirits of the dead. I know this because I have experienced it firsthand.
In 2008 I heard Julian Barbour make a similar argument in a CBC radio documentary called "Living on Oxford Time". He said that (effectively because of frozen spacetime) he considered Julius Caesar to be just as much alive as he is. This bothered me so much that I spent ten years trying to work out how you could unfreeze the block universe. Eventually I came up with a way to do this, that requires a different perspective on space and time, but which seems to be able to solve quite a few other chronic physics and cosmology problems, including dark energy and dark matter. Only the dark energy idea has been accepted for publication in a peer reviewed journal so far ("Matching supernova redshifts with special relativity and no dark energy", April 2020, Journal of the Royal Astronomical Society of Canada). Check it out!
The way I understand what she's saying is this - in space, I occupy a certain place and that is where I presently am. There are many other places that still exist regardless of me being there or not.
The present moment is just a certain 'place' in time, and other moments in time still exist whether we are presently there or not. It's an interesting idea.
My first foray into the subject of time was with a book I read when I was 10 called "A Wrinkle in Time" by Madeleine L'Engel (yes, there apparently is a movie out now based on the book but I have not seen it). The main character's dad (an astrophysicist) disappears and she eventually goes looking for him with some "time travellers". It was a wonderful story, maybe just outside of my comprehension at the time, but I reread it over and over as I grew up and always felt that there was an understanding there that was just beyond my reach. Dr. Hossenfelder is a fantastic teacher as I now feel as though I grasp the concepts better!
The concept of entanglement in theoretical physics relates to the SIMULTANEOUS action of two objects separated by huge amounts of space or time. Some research has provided evidence for the actual existence of entanglement. Various research findings are revealing that the universe is much more complex than has been thought in the past and that many things previously thought to be physically impossible may actually be true.
Science has all the answers we seek. I've always found it difficult to rationalize that a human only exists a certain amount of time and then their whole essence is gone forever. It does not make sense- her explanation of the science is brilliant, relevant and makes a point not often echoed in her field. New hero❤❤❤😊
OK Dr fauci relax
you do die and then are gone forever. The fact your atoms still exist doesn't mean you do. Nothing she said was really wrong, but it was all worded in such a way to sort of affirm new age hippie stuff
See you in Heaven.
Science is good at explaining how., but not why.
@@Doogyrevkowow there is no why
I subscribed to her channel after watching another one of her interviews and she's great to listen to as someone who didn't study advanced physics but likes to know how the world works
Well spoken 😊
