Neil deGrasse Tyson & Janna Levin Answer Mind-Blowing Fan Questions
Вставка
- Опубліковано 2 чер 2024
- Is gravity fundamental to the universe? Neil deGrasse Tyson and Chuck Nice explore quantum physics, the fourth dimension, whether H2O is water, and the many-worlds interpretation with theoretical cosmologist Janna Levin, PhD.
Is space infinitely elastic? If spacetime is a particle at the smallest scales, is there space between spacetime? We get philosophical: is H2O water? We explore the quantization of space, Planck lengths, and whether gravity is an emergent feature of quantum physics. Is gravity a fundamental feature of the universe?
What would you see in the earliest parts of the Big Bang? We explore how you could rewrite relativity as particle field theory and the geometry and topology of the universe. Learn about the time Einstein let his driver give a talk for him and how the 1919 eclipse changed physics forever.
We break down the fourth dimension, compactifying space, and Lorentz boosts. Do physics and math view spacetime differently? Neil and Janna discuss the many-worlds interpretation and whether it’s trying to make classical sense of something non-classical. Plus, we explore how quantum teleportation would work. Is the universe in a superposition? Are black holes fundamental particles?

Did you get your mind-blown during this episode!?
No.
Thanks for watching!
I'm in love
Here is a question Neil. If the universe is accelerating, does that mean time relatively is speeding up too and we just dont notice it cause we are in the universe.
Why is Chuck so sleepy this time?
I love how Chuck, over the years, seems to be understanding more physics.
Same, it goes to show he isn't just sitting there waiting to make jokes, but rather he is actively engaged and interested in the conversation.
I don't think anyone who spends time with The Tyson can pass themselves off as "uneducated." With all the years he and Chuck have hung out, The Nice could run his own show if he wanted to!
If only Carl Sagan had a comedian to bounce things off of, it would have been the only improvement he may have needed. Who could have been that comedian? For some reason, my mind goes to Buddy Hackett. 😸
@@Mad-BassistWait, George Carlin???
I got that too.
It's called Active Learning.
We see Neil and Chuck: we Click.
We see Janna : We Grab the Popcorn.
Nailed it
Obviously the human form stretching ability will also change in terms of texture to stretch. Twisting unraveling plasticity after the transformation of it being stretched. Gravity grows and is apart of heat.
Totally have a nerd crush on her! She's great.
@@GinaCarmichael-nd2pt
Would you mind rewriting this as a Haiku???
Awe cheers! Now I want popcorn and don’t have any. 😢
Constructive criticism from South Africa:
Hey Neil,
I'm a big fan of your show and appreciate how much you share your knowledge.
One thing I've noticed is that sometimes you cut your guests off mid-sentence. While I know you're enthusiastic to share your thoughts, it can be frustrating for listeners who want to hear the full point the guest is trying to make.
I've learned so much from you and your guests, and I think letting them complete their ideas would make the show even better.
Just a suggestion! Keep up the great work.❤
Your lucky to get a word in sideways with Neil he's brutal
He interrupts her to explain something she said that is at a higher level than the average listener. He makes sure people can follow what she is saying & comprehend her point.
@@Michelle-hh5deyep that’s it
YES!! He needs to listen Dr Peterson is the same way
I only listen based on their guest that I am interested in. And hope they don’t ruin the show
Should change it to... how to answer the first part of every question.. talk for an hour, and answer nothing.. if something gets too over Neil's head.. shush everyone and move on.
This was by far my favourite StarTalk! So many revelations in my own head. Thank you.
🙏🙏Blessings forever GOD loves y'all too forever tell everyone you know and don't know. Jesus loves y'all too forever. Teach everyone how to see and enjoy their blessings too forever😊
That is because its a new revelation in science. This is a break through in science that may or may not be right. It has to be tested and proven just like everything else its a hypothesis that need to be a theory to be proven. But yes this is NEW Science. The revelation you have is no different from the scientist that created the theory within the last 5 years
Janna is my #1 favorite guest of all time. She is such a wonderful science communicator and person. I love her chemistry with Neil and Lord Nice

It's really messed up when fans can't really ask real questions.
It's always great when Janna Levin is on the show. Brilliant Episode!

these talks with janna levin are legendary. absolutely amazing!
I used to vehemently hate Neil because i thought he was arrogant, and a know it all, and obnoxious. This was difficult due to my love of cosmology and science at large. He would come up in numerous videos I watched and he just sort of became a necessary evil in my search for understanding of the universe. But the more he came up, and the more I listened, and heard not just what he said, but also how he said it, and who he is and what his mission is as a human, I can now say I genuinely adore the man. I say this because as I was listening to his monologue at the end and I was staring into his eyes, I realized how much I love and respect him as a scientist and a fellow human, and was struck with this weird feeling that I somehow used to despise the man. Listening to a persons words and learning their heart can change yours. If there is someone you hate today... maybe give them another chance, maybe 10 or 20 or 100 more chances, like I did, and you may very well realize your hate is simply misunderstanding, or your own ignorance.
Thanks Neil for making the Human Race a group I'm proud to be a part of.
👏
I don’t get people that hate the man.
I’ve only loved him since I first saw him on… gosh…what was it? The history channel back in the day? Discovery? Or was it early Netflix app days?
@@user-dj9iu2et3r I think people mistake a knowledgeable person's passion as arrogance sometimes. Mistaking - especially scientist's knowledge - as absolute, when in reality we're all discoverers and we're all ignorant. Science is just the most efficient method by which we've discovered to make accurate predictions and useful products, so far.
I doubt any scientist alive believes we're even 1% of the way along revealing everything in their specific field - compared to the vast uncharted worlds of knowledge our descendents will discover this millennium alone.
You were right about him the first time.
I understand this. I didn’t like him and the way he spoke. He grows on ya when he’s acting more modest and has less pretense…
I need another live Startalk with Janna Levin!
She's been on here 3 times lol
🙏🙏Blessings forever GOD loves y'all too forever tell everyone you know and don't know. Jesus loves y'all too forever. Teach everyone how to see and enjoy their blessings too forever
Charles the asian looking professor is also a good guest .
You need to have a 2 hour show for these 2. I love it when she’s on. I hope you have her on again soon.
🙏🙏Blessings forever GOD loves y'all too forever tell everyone you know and don't know. Jesus loves y'all too forever. Teach everyone how to see and enjoy their blessings too forever😊
It’s amazing how studied/knowledgeable/intelligent these people are. I wish I had the mind needed to be this smart.
If I can go back to my teen years with the knowledge that I have now, I would become an astrophysicist. Ever since I was a kid, I always looked to the skies knowing that one day I will see something extraordinary. Thank god for podcasts. We definitely appreciate you and chuck. Keep feeding us knowledge.
no you wouldn't. you'd still be terrible at math, which is 95% of the degree.
@jotarokujo5132 I think what they are saying is that if their teenage self had known how interesting the subject is, they would have gone to college for astrophysics.
@@jotarokujo5132so much negativity...ugh lighten up
I would look into astro physics too, maybe in theoretical physics and I am good at math.
🙏🙏Blessings forever GOD loves y'all too forever tell everyone you know and don't know. Jesus loves y'all too forever. Teach everyone how to see and enjoy their blessings too forever😊
Chuck I got you covered. Had to rewatch with some slight "elevation" and oh my. Janna and some of the things Charles Liu pops off with completely blow my mind. I love it.
Your're like "Wait I'm levitating right now? Whhhaaatt?"
🙏🙏Blessings forever GOD loves y'all too forever tell everyone you know and don't know. Jesus loves y'all too forever. Teach everyone how to see and enjoy their blessings too forever😊
@@ChargersCity What?
I gathered a small part of this so far, what I did gather will not be retained and I love it.
So true!
Not blown away yet still digesting what was said and forming new questions in a bit of a different direction. Changing the way you investigate relativity with different data input. This way of looking at old formula I think I am able to understand better how a friends discussion on how the bending of light could be the source of gravity without gravitons. And the realization that my friends have a warped way of thinking, but now I see better how they are thinking thanks to Janna Levin and to Star Talk for opening a new door in my way of understanding reality and my warped friends.
Great, guess I'm staying awake for another hour then!
Hahah it’s 1:20 am and I was just thinking the same thing right before I read your comment
40 mins if you watch @ 1.5x speed.
(Or in just 1 second @ 2400x speed 😁😁)
🙏🙏Blessings forever GOD loves y'all too forever tell everyone you know and don't know. Jesus loves y'all too forever. Teach everyone how to see and enjoy their blessings too forever😊
I love how Chuck is embodiment of everyone of us, who actually didn't knew much about astro physics when this journey was started but over the years with such great communicators and teachers in the show, we all now feel at home now.
While it's still a long way to go, but we all are so much more knowledge richer than when we started listening to this wonderful show.
I thank you with my warmest heart to all of the team that works to bring us such educational and entertainment rich show.
@@ChargersCity What does that even mean?
It took me a year to understand the title of Janna's book " A Madman Dreams of Turing Machines " . Janna is a gift , so grateful for all of her remarkable work. ❤from🇨🇦
It is a profound juxtaposition that implicitly challenges the nature of reality. After all, in the quantum sense, reality is just a position.
🙏🙏Blessings forever GOD loves y'all too forever tell everyone you know and don't know. Jesus loves y'all too forever. Teach everyone how to see and enjoy their blessings too forever😅
🤯
Is this Janna ?
How can you fit that much information that can be immediately accessed into one human brain and still not only have enough room left for common sense...but a great sense of humor to top it off...and wrapped up in a beautiful package...
These are always so good! After a long day just to think about how big the universe is and question our own existence. I thank you for taking the time to discuss these topics.
Awesome podcast!!! Please have her a regular! So interesting and inspiring to be able to explain such complex concepts in such beautiful and engaging and understandable ways!
Ten out of ten!!!
The last minute or so of the video is what we're all here for and what made Startalk what it is today. Neil, when u talk like that it puts me in a trance. Please give us more of you and your way of communicating in future episodes. I miss when YOU were the focus. Im not trying to discredit anyother person associated with Startalk. But your the true 🌟
I've watched dozens.
This is one of my favorites.
Janna Levin is an absolute fave! I've been following her for years and she never fails to say something that blows my mind.
I love conversations like this. Things that make you have to think about it deeper. Things that make you go huh that make you question your own thinking. Keeping an open mind to learning and also thinking about the possibilities of all things .
One of the joys in life is to examine the "what if" about our experiences.
Chuck impresses me listening all these years..bravo. this has to be one of my favourite episodes..
Janna is the first guess I can relate too. The Quantum world makes me question the nature of reality too.
The fault of that is more from physicists losing track of what is "reality" and what isn't. Especially the "is math invented or discovered" argument. Math is a language created to DESCRIBE reality. It isn't reality itself. And so the continuation of that is how you have this "quantum wave function", which is just describing probabilities, being treated as reality itself rather than just a description of it. The grass outside is reality. The word "grass" is the description of that reality. The grass is real, the word "grass" isn't.
@@VaeldargThat’s one interpretation but nobody knows yet what the true interpretation is. It could be that the wave function is actually what is there, and the particle only our way of describing it within spacetime accurately. We can’t assume either way.
@@YivvaMedia Interpretations are not created equal, though. Science isn't about perfect explanations, it is about which one gets the closest. And so the further your interpretation is from reality, it means it is worse, not better.
"It could be that the wave function is actually what is there..." except it can't. Because it's math written just to describe reality and not reality itself. It's a function describing statistical probability, and reality is under no obligation to go by how you describe what you think it is.
Neil and Chuck for 2024!
I think Neil is too smart to run for President 😂
This episode was wonderful! So confused, but amazing to know how complicated and yet very simple everything is.
Thank you , I very much enjoy discussions on these topics.
Talking about notes and cords… the first thing that popped it to my head was A-minoooooooooooooor 😭
#Question
In the TV Series
Star Trek Voyager
The Borg open a “Trans-Dimensional Rift” which opened a “Gateway” to Species 8472 and when Voyager goes through that Rift they end up in “Fluidic Space” when Space isn’t really Space, it is Matter.
So think of Space as we know it Only it isn’t “Space” it is filled with Matter (Think of moving through water like a Submarine) the Submarine is the spaceship and the water is Space.
(Keeping in mind the “Multiverse” would something like that possible AND how would Physics work in that Realm?
Loved this episode of your show.
Wonderful guest and discussion!
I don't know who else noticed this thing but Mr.Chuck seems to have been benedicted with a special talent of picking the exact last words from the sentences coming out of Mr.Tyson's mouth. I enjoy it every time with a pinch of awe in my mind. 😄🫰
I love the chord analogy - a chord is more than the assembly of individual notes, because of the overtones between those notes.
🙏🙏Blessings forever GOD loves y'all too forever tell everyone you know and don't know. Jesus loves y'all too forever. Teach everyone how to see and enjoy their blessings too forever
@@ChargersCity Too bad none of that is true. Just a cult.
@@ChargersCitywouldn’t you think it’s an insult to call him by his romanized name
Jesus troll!
have a blessed day. Beautiful GOD & Jesus loves you forever
I would describe Janna's outlook as "I live the life I love and I love the life I live." How frickin' wonderful!
Love this show. So calming and informative
Janna and Neil two of my favorite scientists. Thank you for this podcast.
Love when Dr Levin is on! The best guest!
Chuck is in another dimension😂
I was thinking the same thing 🤣
Is Chuck real? 🤯
Chuck is definitely high hahahahaha I know that look anywhere 😂😂😂
@@TheRhythmicPrescription 😂😂😂
Thank you Neil and all of your team and guests. Keeping me intrigued and curious is all I could hope. Also, if I may, I should say all of you here watching this as well, with intent to learn something, are all my friend as far as I see it.
WOW! Crazy and unbelievable discussion.
She does an absolutely phenomenal job of explaining complex ideas. And even more impressive, she manages to stay coherent and focused through the constant (I mean CONSTANT) interruptions and peripheral inputs Neil offers. I would have loved to hear her complete her thoughts/arguments to completion. I bet she would’ve have developed them even more impressively.
Yeah but if you notice Neil is mostly throwing in science jokes and a lot of “normal” explanations so other non sciencey people would understand
The content has been top tier
I am thoroughly enjoying this episode!
I've re-listened to previous episodes and the scientific growth of Chuck is interesting to see.
Then thought it most likely mirrors mine!
You should accept an interview and debate Terrence Howard
Neil is so “Mr. I know everything” and arrogant that unfortunately this will never happen?
Why debate when Mr Howard can just write papers on his works. Why should he care what NDT thinks when he can submit his work and let all the scientist of the world read and decide for themselves.
Neil; So....Neutron walks into a bar. Sits down, orders a drink. The bartender brings him his drink and says, "For you, no charge."
Nah. Neutron doesnt think. Doesnt order, its empty
So, a neutrino walks through a bar...
They have a neutral charge tho...
But if it's alone, it can only stay a few minutes
@@jayfredrickson8632 max 10 min apprx.
Gotta get up in 3h for work, worth it
Great episode
These discussions always trigger a memory of watching 'Horton Hears a Who'....I mean that in a good way! And I adore the Einstein and driver story. Thanks for posting :)
Ohh im SOOOO rrady for thia video! I love jana levin!!🎉
General relativity and quantum mechanics will never be combined until we realize that they take place at different
moments in time. Because causality has a speed limit(c)
every point in space where you observe it from will be the closest to the present moment. When we look out into
the universe, we see the past which is made of particles
(GR). When we try to look at smaller and smaller sizes and
distances, we are actually looking closer and closer to the present moment (QM). The wave property of particles appears
when we start looking into the future of that particle. It is a probability wave because the future is probabilistic.
Wave function collapse happens when we bring a particle into the
present/past. GR is making measurements in the predictable
past. QM is trying to make measurements of the probabilistic future
Hey wow!! Nice thought/explanation!
This perspective is very interesting, but it oversimplifies the complexities of unifying GR and QM.
It overlooks the spacetime continuum's role, the current theoretical efforts like string theory, and the various interpretations of quantum mechanics beyond the Copenhagen interpretation.
Oh, I like that.
I think Roger Penrose would expand on that and say- at great distances when individual particles can have no interaction with any other particle, the scale of space collapses. What was a hot vibrating particle no longer has a reference against which it can be seen to be vibrating - so it becomes totally cold - totally organised.That is the state of Entropy swaps state when scale and relative position can not be measured.
I'd like to add - information, the observation of any interaction, the structure of relationships is also scale dependent, like one H2O molecule is not 'water', but two of them may be able to interact AS water. They observe each other.
Janna is the BEST guest. I wish she could be a regular. She is so immensely intelligent and yet answers questions and makes them so easy to grasp.
Chuck needs an honorary grad degree with how much he has sponged up over the years. Fabulous to see someone who used to think on a more juvenile level to relate and comprehend on a more upper scale level!
Props to him for being so curious and taking the show serious enough that it benefited him! Keep it going chuck! I remember forever ago you used to joke about StarTalk forever being on the air.......BUT maybe the torch can be passed to you in due time.
The existance of only one electron in the universe that simply runs back anf forth through time can explain a lot. 1) why they the same 2) problems of large numbers: in a universe with a mass of 10^56g approximatly 10^80 electrons and the ratio of the visible universe size to the electrone size exatly 10^40. That is just one layer to go back in time 3) the experiment with two slits is easily explained 4) positrons just electrons moving back in time 5) collision of electron and positron destruction of the loop. Therefore , there are so few of them for the whole structure to work.
This is blowing my mind 😮😮
Wow. Then perhaps the logical conclusion in such a setting is that there is only one sole entity for each kind of quark and lepton. Sure is trippy!
Fun fact, this theory was just a meme
Neil let her talk stop interrupting oh my god
😂😂😂get off the man’s smart opinions
I am always amazed at the richness of the human mind! There are so many mysteries. I love this channel! New Patron member!
We, as a society, need programs and communicators to share current science with us.
Yeah, we need more of Janna! My favorite guest on this show.
I believe terrance Howard gravity isn’t holding us down it’s the magnetic force of earth’s rotation
Tyson and Terrance. Make it happen!
Yes
I’ve been watching Startalk since the nat geo days and Janna Levin is easily one of the best guests you have on. I like when guests and the hosts can all be in one room. Face to face interaction is better than webcam interactions, though webcams are convenient and allow guests at a distance to be on that might otherwise not be.
The most fundamental thing I've seen from this clip is the incredible accurate impression Chuck does of Neil "You know there's no such thing as gravity now"😅
your measuring is the partical in universe. so wouldn't it not care if its in milky way or Andromeda it scans the reality to see if it is still exists or not. the question is can you send it and it not pop up? that would mean it left the universe which is the first steps to traveling to the multiverse.
You guys further my knowledge of space. It terrifies me and I love it 😂
Neal, Janna, Chuck.
The one electron theorem was explained in Dion Fortune's 1942 book, "The Cosmic Doctrine".
Ring Cosmos (the attraction to the center and the inertia of remaining still), Ring Chaos (the attraction to the circumference and the inertia of remaining in motion - which left unchecked would continue on to oblivion).
The Ring-Pass-Not becomes the balance point that holds everything within the toric field).
And that is the point of manifestation.
(That is what string theory shows.)
The initial movement between Spirit and matter, once set in motion will continue around indefinitely.
So yes, until the Oroboros is filled to satiation it is as a plane of existence. Once filled or satiated the Oroborus opens up to exhibit itself as a spiral and then there is a splitting off akin as to one cell becomes two.
The inversion points are akin to the Guardian of the Above and the Guardian of the below, both of which are our reflections mirroring back to each of us our level of consciousness.
It's one electron and it ALL OF US.
See, so WE ARE ALL ONE!
This sounds very Terrance Howardish… just more scientifically coherent
Are you saying TH's theory is NOT scientifically coherent..?
@@SydneyD28-6 no I’m saying the communication here seems more coherent and precise even though the overall idea seems similar to his
"If...maybe...could...might...what if...possibly...perhaps..."
That is theoretical physics for you.
Thanks! Brilliant and informative as always. Also, you both are getting sleepy! Your coffee is on me!
It is very pleasant and interesting to listen to you science-nerds talking about the forbidden large and small. Thank you for sharing.
Worse things in life than getting closer to Janna...
Yeah but dude needs some space to stretch out and move around, he looks mad stiff and uncomfortable cause he doesnt want to be in her space, they gotta move in a bigger space lol or move him to the middle
Jenna is an attractive lady. But her intelligence is what causes her to win any hand of cards.
@@bradheath4200Since you said it first…I usually have a thing for Janna, but she seems to look older for some reason in this episode. Being that she’s so intelligent I find her so attractive but not as much on this one.lol I’ll admit that it’s not “cool” to deduce her down to her looks because she’s so much more than that. But since you mentioned it, I had to share my ignorance. lol

Great Show, Cracking Guest too. Thanks too ALL 👋
Janna, marry me and teach me about the universe
DEBATE TERRANCE HOWARD!!!!!
“Mayne”
Teaching Terrance his multiplication tables is not a debate.
that would be incredible or Alex Jones lol
He’s shaking in his boots
😂😂
Love this stuff. I just wish Neil wouldn’t keep interrupting to add his two cents onto everything
I think superposition describes the wave function which won't apply to the particle. In transit energy takes wave form and when it contacts a surface that can absorb the energy it reaches it's destination as a particle. What we know as particles are like the holes left behind when a rifleman shoots a target, but to make the analogy work the bullet would be pure energy and travel as a wave.
Waves also can't be seen by us because of the fundamental properties of waves and our sense of sight. Our sight works because waves of light are reflected off a surface and hit our eyes which take those particles and with the help of our brains were able to get an image of whatever light enters our eyes.
On a side note I think it's incredibly fascinating how light can relatively accurately portray everything around us. The pure mechanism of light bouncing of a surface and then interacting with our eyes to form shapes, colors, depth, and everything else, it's hard not to be humble.
the crux of your idea (in my limited understanding) is that light is both wave and particle simultaneously....only until an observation or measurement is made....which then collapses the light into particle form....such as the double slit experiment suggests...
For the longest time I thought her name was Jan Eleven ha
I’ve heard ….stranger things. ;)
@@moonshoes11get outta here 😑 👉 🚪
Terrence Howard said he wants a debate with Neil
“So you’re saying gravity may not exist as a fundamental thing in the universe?” …. That sounds an awful lot like what Terrence Howard was saying on JRE
Yes, yes, yes!
Janna is one of my biggest celebrity crushes. She's gorgeous and brilliant.
I love Janna. I've been reading her articles and interviews for decades
Neil is the very definition of someone who literally loves the sound of his own voice, which I suppose we all do to varying degrees. I just wish he'd learn to allow his guests to speak occasionally.
If you've never interjected in an intelligent conversation, then you've never had one.
@@lonesom You obviously have never watched Brian Greene and his guests, for example. I challenge you to do so and tell me he's not engaged in an intelligent conversation.
@@lonesom And neither have you if you interject every time someone else talk. Neil is notorious for this. He's always loud and obnoxious, and he always talk over and interrupts everyone. It's even more noticeable on panel debates where he's impossible to deal with. Even when he's moderating debates he talks way more than the participants. You're not particularly bright if you think that's how "intelligent conversations" are conducted.
@@oaksnice You appear to have lots of examples.
i wanted to hear Janna speak more and he kept interjecting at the wrong time and ruining the flow. She handled him well though
She mispronounces Schrödinger in multiple ways. Does this mean that elsewhere in the multiverse she pronounces it correctly?
I think she's from another universe where they pronounce it that way
Par meee zian
Maybe
Chodedinger
Yes, for sure.
Just a good way to enjoy spring here in Denmark, sitting on my deck, drinking iced coffee and listening to star talk, take me away 👍
Tools differ, curiosity is the same }}} Thanks for a wonderful journey!
The Einstein story is just a joke, it's not real 😂
Next guest TERRANCE HOWARD, don't be scared Neil
It’s interesting how Neil and Janna explain the unfolding of “the big picture” in changes with scientific theory. I wonder if the assumption that “science is ‘about’ overthrowing the old theory” comes as a consequence of political thinking.
Gawd! I had to wipe the drool from my mouth. Mesmerizing episode, thank you to all three of you. I remain curious and humble 😊
If I had to drink every time these two interrupted her while she was speaking with their feeble attempts at humor, I'd be dead. She's obviously the smartest person in the room, but the egos or the manners (or both) on the other two are so out of line that they just can't shut up and let her finish a complete thought.
Dude it was so annoying
Maybe they have bad timing and don't mean bad. I don't understand why they would invite her otherwise. I really believe they try to make the discussion also light-hearted for the audience. I understand it can be annoying if you want it more serious , I find it refreshing in between more serious physics videos that exist
@@astralmeaning111 Humor is fine, but they literally just keep stepping on her comments in a very rude way. I found it horrible. And Chuck has no business even being there. He’s not funny, not educated, and just drags every video down.
Yeah that sucked, she was very intriguing too
@@bryantrodriguez6288 Yes she was, and you can clearly tell that not only is she brilliant, but she knows how to explain things in terms that the common person (like myself) can understand. Hopefully they'll have her on again soon and practice better manners.
By definition a molecule of H2O is water, it may not be recognizable with the properties of water at the macro scale, in fact as water separates we call it vapor or steam.
Neil's speech at the end of this video reminded me of the Key and Peele sketch 😆
One of my favorite thought experiments is assuming that there is no gravity, and that the force we attribute to gravity is simply due to time gradients.
In the discussion about rotating euclidian space via a lorentz boost, something in the description right after felt off. You can't actually orientate something within 3-dimensional space without utilizing the lorentz boost (time), or treating it as a portion of a four-dimensional euclidian object being observed in 3-dimensional space, which can be oriented in a separate way from it's other fourth-dimensional counterpart in any 3-dimensionally observable way without breaking 4-th dimensional consistency; but you cannot re-orient something within 3-dimensional euclidian space not utilizing another form of dimensionality without breaking the euclidian space to do so. That is to say, 3-dimensional orientation is static; as are any observations within it. It would be like taking a holographic photo of a room, and never being able to reorient the things in the room without altering the photo or utilizing time in order to accomplish 'change'. Whether that be change in observable perspective, or change in the observed space (eg, people growing physically older as time passes). 'Change' of 3-dimensional space is thus possible only in a fourth dimensional sense, either reconfiguring the observable orientation of 4-dimensional euclidian matter, or considering the natural 'change' of said orientation as 'time'- 4-th dimensional movement observable in our 3-dimensional euclidian capacity. It's much like the common misconception people have of light being the speed of time- that's not accurate: as a thought experiment, let's say there are three stars, stars A, B, and C. Stars A and C are moving directly away from each other at just over half the speed of light, while star B hangs out directly in the middle. Let's say each has a planet with a civilization eventually capable of light-based communication with each other. Light from star A and C will never reach one another; their combined movement would be too fast for light. However, both A and C can communicate with star B. Let's say that star A communicates a message to star B at (for simplicity's sake) one light-year of distance from star B. It reaches star B one light-year later, and they then communicate that same message to star C when they receive it. Star C is already a light-year away, but moving at just over half the speed of light, they'll receive the message from star B that was sent from star A approximately 1.5x more the amount of time it took star A's message to reach star B. Ala, not infinite time. Likewise, light not being a barrier for information exchange. This separates light from having anything to do with 'being' time, it simply measures it in a scale, as Farenheit or Celcius measure temperature. Time exists regardless of light's interaction with it, but our own ability to observe distance- space, is limited by our observation of light through time.
On another matter, touching on the question regarding the stretchiness of spacetime being finite; in classical theory, if spacetime is not infinitely stretchy, black holes should be 'eating' vast quantities of spacetime far more than what we consider 'matter'. Thus, white holes should expel far more spacetime than matter, and should realistically be observable as cosmic voids. Yes? By some theories, inside a black hole would be a vastness of space compressing possibly leading to a white hole; if this is the case... if a large black hole eats a smaller black hole, if matter and spacetime is swallowed by the blackhole in a causal sense (one thing getting 'eaten' before another), in theory if a swallowed black hole by a black hole means a white hole expelled from a white hole, the distribution of both matter and spacetime/void into a blank canvass lattice would not be even, as say, a black hole that has become a white hole which gotten 'eaten' before another different black hole would come out as a white hole expelling its own 'eaten' spacetime and matter causally before the other 'eaten' blackhole turned whitehole comes out and begins expelling its own 'eaten' contents of spacetime and matter. Ala dark energy, and uneven matter ...what's the term here...? 'Creation'? 'Observability'? Matter's 'coming into existence' within our observability of the universe.
I realize this is long; I felt it worthwhile to share these thoughts.
Thank you all for continuing a place for the good conversations. Just wondering if there is any evidence of a molecular harmonic resonance of “consciousness” or agreement of reality, and the discrepancies of frequency are the alternative “energies “ and dimensions we are starting to acknowledge?
Aha! - knew it all along - you guys are fun!❤
I've heard Neil give this nice explanation of how new research will not "rewrite" physics. It may be helpful to draw a distinction between physics and other sciences that may often end up flip flopping on "findings". For example, it's not uncommon for separate human trials of the same drug to have opposite results. There are rational reasons for these results, of course. I'm just pointing out, that in some fields, we have become accustomed to "science" being completely changed.
Love ur content thank u for keeping me curious! Since I was a kid I love to stargaze. When I was having a bad day or just time alone I looked up at the stars and made me realize how small I actually am and how I wish I could know all the answers good or bad. I always had curious mind. I have come a long way in my journey but can’t wait to learn more.
