#InfiniteUniverse #HowBigIsTheUniverse #CoolWorlds - Наука та технологія
This is the best channel in the observable UA-cam.
Have you found SEA. Thats great too 👍
@@MrJimtimslim definitely!
Humans are their obsession and mental masturbation with best athlete, best this, best that, best physics youtube channel...all so immature and silly.
@@fitnesspoint2006 jeez I bet you're fun at parties, i think he was joking, there's obviously a better UA-cam channel somewhere in the observable universe....it's massive 😂
@@MrJimtimslim and ever expanding! 🤣 and yes I was joking.
Its remarkable how this question weighs in my mind yet has no real bearing on my life whatsoever. I shouldn't let this make me forget to brush me teeth.
Why brush em? There are infinite teeth out there for you to harvest. And they are all already yours! Quick, go get em before another you gets the same idea before you. Shit, the infinite me's who are 15 minutes ahead of me told the infinite you's the idea about 15 minutes ago. Get the pliers, they're on their way.
Yargh! Don't forget the rum also matey!
@fuffoon: UY SCUTI- Am I a joke to you??? LOL.
@@ICreatedU1 that was a truly life changing comment to read

I can PROMISE you, Prof. Kipping, that your own impact on _this_ world through your videos is far greater and more positive than anything you could imagine.
Single-handedly reignited my passion in astronomy after falling out of love with it twenty five years ago. I never thought I’d pick up a peer-reviewed paper or get out my telescope again and his videos made me crave this knowledge again. Thx for your post
He has done so much for my understanding of this place we live in.
A note to a great comment from a few months down the road.

if he doesn't believe in God he doesn't know anything
Every time I finish one of these I feel like a changed person. Thank you really for making these and keep up the great work Dr. Kipping.
Ditto.
Sometimes, when I watch these videos and they end, I feel like I'm coming back to Earth from a trip to space. :)
Smoking weed is bad
@@thatswhatithought6519 no, it's pretty good! 👍😎👍
I know what you mean my friend!
Seriously! I fall asleep to his “Journey To The End Of The Universe” video every single night😂I feel like I am literally traveling the cosmos lol
Yeah, it feels bad this time ya know? An infinite number of me doing infinite things and here i am sitting in my chair, no pants, crumbs of potato chips on my face watching UA-cam vids.
"Even the smallest acts of kindness can carry infinite weight..." Such a revelation after hearing all the potentially infinite suffering, potential infinite happiness also co-exists. What a truly mind boggling life, how fortunate we are to be able to ponder and explore such things.
I was thinking just the same, kudos for that deep thought!!!
Well said!
Imagine how lucky we are to have in our body mechanisms that can translate electromagnetic waves with different frequencies and wave lengths into colors to see our ironically beautiful colorless universe, acoustic waves into vibrations in the eardrum that our brain translates into sounds something which doesn't even exist in the world but was defined by humans, a huge system that covers every millimeter in our body and responds to internal and external forces by sending electric signals to our brain, and of course amazingly complicated connections between neurons that create an enormous structure of information stored in an unbelievably small place.
After all this, it feels wrong to call even the stupidest person in the world, stupid.
Yeah some people can make a cabbage sound like a golden hens egg take a bite it's still a cabbage. Or you can paint reality into whatever perception you want but reality doesn't give a fuck
@@devrimkay1636 completely agree Kay! This homey talking about "infinite happiness" LMAO its a very child-like view of the world.
Easily the best piece of science communication I’ve ever seen. I used to be an entertainment science communicator as well at one point, primarily focusing on astrophysics and astronomy, and this is easily the best I’ve ever seen. The way you broke down and explained some of the most difficult concepts out there is nothing short of amazing.
From looking through a 29 inch reflector telescope in 1984 and seeing the veil nebula for the first time, I’ve always wondered whether or not the universe is infinite. Infinity of space holds my interest more than anything else.
Is the universe all the matter that exists, or the space that the matter exists in? If it is the former, and the galaxies and nebulae are moving away from each other, maybe it is the outward motion or expansion of matter that is infinite. Space then is absolutely nothing and the 'universe' only exists as long as matter itself exists.
@@stevenbrooks3573hmmmmm, good POV
I believe the astronomers/scientists say it"s +/- 13 Billion light years...Who knows if it has a end point or is infinite.
I mean our minds literally can't comprehend infinity.
If the universe isnt infinite what's there gonna be a wall you can't cross at some point?
@@nickhayden2299no
I've never felt so touched and at the same time uncomfortable. The las part of this video is a true masterpiece and this is the type of content all of us should appreciate. Thank you so much.
Who is the guy that talks at the end
@@Pakopako2280 Charles Bukowski
I would imagine that your discomfort comes from the contrary of your beliefs. Such as in a god. We are raised to think that we will go to heaven or hell. But the reality is the reality.
With all due respect, that's your opinion 👌 BUD
@@charlesrosaly I'm a Scientologist and L Ron Hubbard is our GOD and your GOD and will lead us to infinity ♾️
“The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new dark age.” "H.P. Lovecraft"
Terrifying words, perfectly written by a great mind.
The call of Cthulhu
Excellent story
I like that, very much.
That's why there is bliss in ignorance! 🤔
I went mad, because my mind is able to comprehend the infinite madness of the universe and the human species.
I have long been a fan of science channels on youtube, but only recently found yours. I can honestly say this is the first time the true depth of the complete absurdity of different infinities hit so hard. I actually kind of get it now, the stories of philosophers and mathematicians being terrified of the idea of infinity and going insane from the obsession of over it. not that crazy after all
Bro is a poet
The last few minutes was a deluge of feels that I was not ready for. So profoundly beautiful. I hope somewhere, in another universe, they managed to revive my father and he could have grown old and met his grandchildren.
I wish your dad is alive and well in another universe. I love to think there is a multiverse in which my father is alive and well too. Ever since he died, something inside that 9-year-old, bright, leader, happy kid... just broke.
Feel the same for my mother, and your father
Same for me
Maybe our universe is so big and in it's border could starts other paralel ones maybe I don't think it could have limits
I feel you brother...
Anyone else watch it 3 times?
There's so much knowledge in Cool Worlds videos I often find myself having to watch them multiple times to make SURE I understood it.
Journey to the End of the Universe was the first video I ever watched of Cool Worlds a couple years ago... still amazing!
Best space education channel on YT!
Honest commentary certainly reflecting my humble experience. My vastly more intelligent wife agrees.
I saw this video infinitely many times...
i am still perpetually watching this video - somewhere........
It’s 0620 Monday morning and I made the mistake of starting to watch this. I wish I were smart enough to understand 50% of all he is saying. (Change that to 10%) gotta watch this many more times!
I made this comment instead of you in a different bubble-universe.
Mate, once again you have absolutely blown my mind. I’m still working through the relationship between pure science and meaning. Somewhere I’ve seen a theologian speak of science and philosophy as a complimentary set of concepts. You have brought these 2 so brilliantly in this video. Your emphasis on kindness and compassion oin your closing remarks were really inspiring and resonated with the way I feel about the world. Keep up the good work!
It’s not
That deep lol
Two years later we still have no idea
The last 3 minutes of this video brought me to tears
These are the kinds of videos I truly appreciate on youtube
Educational, thought provoking and emotional
I feel the same way. I love these videos. Absolutely stunning.
Same. Beautifully produced 👏
absolutely
❤️❤️❤️

28.55 sums it perfectly , accept defeat in trying to understand everything and make the most of the life you have in this world, which is temporary
Maybe for you, mortal.
Even in futility, defeat should never be accepted and we should always keep trying.
@@Travis_22 every body is!
@@rotshepherd3817 there are those with wisdom and those with little or none of it.
The most quality Astrophysics videos ever with so much depth and intellect..! Thanks, Dr. Kipping and Prof Colin for such out-of-the-world content...!
Have you seen SEA ?
Sea and this guys are the best astronomy video makers rn@@Godwin_J24
Explained far better and more interestingly than 99% of similar videos out there. Bravo sir 👏
I am simply at a loss for words. Probably the best video on this platform. Thank you for the hard work and always inspiring me with wonder.
This one is my second favorite. The first being his "Journey to the end of the Universe". It's brain breakingly beautiful.
@@gyromurphy where is the link to that video ?
Yea this video is crazy. Kinda comforting knowing the universe is likely infinite
27:30 was absolutely heart-wrenching bro
When I clicked this video, I was expecting a ride across the universe. Instead, I got a ride aboard an emotional rollercoaster. Brilliant writing!
The way Prof. moves from objectivity of science to the deep philosophical questions attached with space discovery is just seamless, and just shows the balance one needs to strike between objectivity and subjectivity. Without losing the magic of the universe and without making the errors of religion, he amazingly brings out the spiritual journey that he himself has been through, so that we can be through it as well.
I take solace in knowing my student loans are actually paid off in a far away universe (tear rolling down cheek)
😂🤣
Indeed. (High fives myself in a parallel universe)
Amazing response
😂
dang boy!!!😂
I lost my Husband of 33 years in March, and oh how I've wondered; 'What if we'd gotten to the Hospital sooner?' -It made me feel slightly less devastated when he spoke of those infinite others that are the same!
Peace
I hope you see your husband again 😌
Yes. Some comfort
Watching this again after two years. Dr Kippings videos have excellent replay value. Always understand things better if you watch a couple times.
Simply some of the best science communication I've ever seen. Bravo and thank you for all of the hard work that goes into each of your videos. ❤
No one has yet addressed one problem. Infinite versions of me, down to the last atom, but I (my consciousness) only exists in this body. Those are the perfect copies of myself, and yet, different consciousness than mine. It does not add up. Should be the same consciousness
This was the coolest, and most thought-provoking video on space I have ever seen! Well done!
Why provoking ?
@@orchidahussuhadihcro9862 "Thought provoking", not just provoking. I left off the hyphen... Thought-provoking: stimulating careful consideration or attention
This professor is a philosopher trapped in the body of an astronomer. xD
@@MasterWright you mean fascinating
@@standardecover7041 that too.
I never thought an astrophysics channel can make me end up in tears. More than once. This channel is gold!
not sure how I landed on one of your videos but I am hooked. if more educators in the sciences were as impressionable as you, We'd see a wave of new generation scientists. Thank you!
At the end of every Cool Worlds video, I take a long deep breath and try comprehending our existence, place and future in the universe. Very deep and thought provoking videos. The more I learn from this channel, the more I learn what I, and most people on this tiny speck of dust and water in this vast universe don't know. Marvelously great content. ❤️❤️
We are simply animals on this planet. No higher purpose we are simply curious. Much like cats 😁
Cool Worlds is a unique mix of solid science and existentialism, I can't get enough of this channel.
Professor Kipping, this may be my 10th or 12th time through this one. You guys have so many that are that good. Ever since I've been a little under the weather I'm spending a lot more time talking to my cat and watching these videos. So thanks for helping me heal.
That's an unimaginable distance. It's hard to imagine just a light-year but 40 billion is impossible to comprehend
a light year is impossible to imagine
Your videos give me reason to be humble, to be kind, to be patient, to try & treat people as they would like to be treated. Amazing work!
You are like the Carl Sagan of UA-cam era...
Man the way you present this blows my mind
WHAT a video. Wow I am absolutely stunned at how thoughtfully written and presented this is. Bravo 👏
A 30 minute video that felt like an hour. Cool Worlds touches on the variations of reality that I've tried to consider. Thanks for trying to take those those thoughts further.
There is something so comforting thinking about an infinity of me's watching this video and thinking about each other for the first time, be well brothers!!
I've been around this subject of infinity and the multiverses (local or temporal).
The concept that everything that may happen happens an infinite amount of times through infinity isn't new for me.
That been said...
One and an half year ago, my 8 months old daughter choke with a piece of toy. When she was turning blue and passing out I did what was like impossible, I grabbed it with the tip of my fingers through her tiny mouth and throat and pulled it out. I hurt her so much that my wife and I had to take her to the hospital right after. My baby took a week to fully recover.
But something was off. When everything was in the balance, I felt like chance did it. It was highly improbable. It just happened independent of anything.
I had many nightmares after that of me living my life after this event gone wrong. I even had a nightmare about a funeral, and that frightened me the most.
It's like that in many other probable universes the outcome was definitively bad.
How lucky am I to exist in one of many universes where I can see my daughter grow up?
So in this infinite fractal of chaos, I'm the luckiest man there is. :)
Be grateful for what you have, an infinite many others of you may didn't get that chance.
That is a fallacy
@@roseroselyne9045 Care to elaborate?
@@marcelosinicoIgnore that weirdo - It's totally normal and expected to have horrible nightmares after a traumatic event like that, so don't overthink it. I'm sorry you had to go through that, but your daughter will be able to tell the story of how her dad saved her for many years to come.
That’s really impressive. I’m glad your daughter is okay👍
I’ve searched for this video for over a year. Finally! It’s just as good as I remembered.
Your videos blow my mind on a level which frightens but yet absolutely thrills me. They keep me grounded from the insanity of this world that threatens to depress me on a daily basis. Thank you for these informative and beautifully produced and easily understood videos.
This is the most broken down, yet unsolved video of the universe I have ever seen man.
The last few minutes left chills in me.
Y'all keep up the great work 🙏🏽🔥🔥❤️
I love how the knowledge of how insignificant we are triggers my anxiety.
Yet here I am, my thirst for astrology takes over any panic attack.
💯%true bro
You probably mean 'astronomy.'
@@spaaaaace8952 yeah man whatever. Space n shit
Imho, the anxiety belongs to your ego (El Padrone) and the thirst belongs to you (consciousness).
@@MrProjectmayhem 😂
Just sitting in a chair in front of a camera , how beautifully you have dissected a complex topic in a way comprehensible by all . The last 5 mins where he brought in a philosophical perspective is superb . One of the best videos I have seen .
Thank you for creating this very informative video. I am obsessed with theorizing about what the universe could look like from the outside (if it wasn’t infinite).
Admittedly, I'm at a place in my life where I'm very susceptible to emotional things, but either way, this was a very moving video, especially the way you concluded it. I couldn't agree more about finding meaning close to home, in the world and people around you.
I'm so glad I found this channel. Every video is packed with so much information and provoking thoughts that I can watch the same video several times and each time I would discover new things and have another epiphany.
This is perhaps the most moving physics video I have ever seen. The fundamental message that comes out of this video has nothing to do with physics. Take care of your loved ones. Be kind to other people. Take your head from out of the clouds and focus on whats really important. Your loved ones. Beautiful video.
“Even the smallest acts of kindness can carry infinite weight.” Make someone smile today. 😊
Coolworlds I subscribed to your channel a couple of weeks ago and I have been watching almost your entire library of videos, they are absolutely amazing, space is a fascinating subject that I've been interested in but thought myself to thick to understand it all, your videos have made it easier to help me understand it better, please never stop you are such an inspiration. Thank you.
This video, which I watched for the third time, illustrates that a branch of our knowledge which is complex and difficult, is actually far complexer and difficulter than I had imagined.
I've watched and listened to more physicists than most non-scientists would consider healthy, but this program took me to an entirely new level of consciousness - presented by the sort of guy who could make you understand calculus.
Dude when i was tripping balls on mushrooms a few months ago, i closed my eyes and saw the connections through cosmos, and how everyone was linked through cosmic energy. I could see myself whooshing through the galaxies and stars, 500 times the speed of light, just shooting past everything like in hyperdrive. It was only short, while i closed my eyes, but it gave me such a immense appreciation for the scale of the universe, and how every human on earth, and all other life forms in the universe are linked, in some way. It was cool man. The universe is awesome.
This gave me goose bumps and made the hairs on my arms stand up. Prof Kipping your communication skills are right up there with Sagan.
As always, Massive respect to the cameraman risk his life just to share us this wonderful footage.
wow very original
I always come back to these videos when I’m overwhelmed with anxiety or stress or anything similar because David’s voice combined with the delivery and quality of the info is an incredibly relaxing combo
Thank you for your work! This is both interesting and inspiring
This kind of video brings so many feelings i cant explain.. and proove me that i dont need to understand. Being alive and feeling is enought. thank you so much for sharing such meaningful thinking.
I love how this channel always leaves me with more question than answers, the shape of the universe could be something we never understand and it's nice to have some mystery left, I've always thought of it as a spherical, if the universe was born from the big bang and we use points of references we can visualize from things here on earth like nuclear explosions then my small mind would expect that the same governing laws of physics to in turn relate itself to the shape of the universe going outward in all directions and then I watch something like this and I'm back to square one having no actual clue about whats going on and being snapped back to reality of bills work and life, I thank you for your channel and the respite I get from the daily grind, even if I may never understand it all, the daydreams I engage in afterwards are a little piece of happy you bring me with each video, keep up the great work!
I'm extremely happy i found your channel. Thank you for these! They're fascinating and so well put together.
Yes exactly. If you ever reached the end of the universe you’d simply find yourself going backwards. But to grasp even the scale of travel time is virtually mind bending.
In the evening when I am watching your videos, I have to go outside and look up. The unknown up there is mind-blowing. Thank you for the content that exercises the imagination.
Your voice draws a person in when you explain things, you have a way of explaining such complex thing in a way that means I almost believe I understand it, whilst creating so many new questions in my mind. Simply the best channel on UA-cam. :-)
I always love your videos. The way you consider all possibilities and are very scientific without bias as to how you reach your conclusions never ceases to impress me.
These videos are exceptionally well-made. They have a very somber nature. They are very nice to watch and listen to.
Along with the premixing raising compression, the seals and surface contact points in a fresh engine will "bed in" and raise compression for a while after the engine is built. Eventually it will start coming down slowly. That's awesome that you still have such great compression!
I've said this before on your videos but...... You are the best channel on UA-cam. You can tell in your voice how much you try and get through to the viewer and care about learning how everything works or why it is what it is. You have a way of getting through and grabbing the viewer with your voice. I truly enjoy watching this channel in my free time more than or any other channel or program. Thank you for taking the time to make and explain these for someone like me to watch and learn also.
I knew there was a reason I loved this channel…… top deep stuff, not just scientific, but mind boggling and very very thought provoking.
I have ADHD and this kept me still for 30 mins, thanks man your videos are entertaining and intellectual.
Absolutely mesmerizing. If you have kids, you should absolutely raise them with this voice at bedtime; if no kids, please share these stories, in this voice, widely and generously.
I forget the exact quote or who said it, but it goes along the lines of: "True art forces the mind into unique and unexpected directions."
By that definition, what you have created with this video is one of the purest pieces of art I've yet to experience. Simultaneously hopeful, wonderous, nihilistic, and distinctly unsettling, all at the same time.
Great video. This and The Exoplanets Channel are the *_best_* channels on UA-cam.
Agreed! Event horizon is a really good channel too.
And Leo restoring the Talley Ho
And SEA
What they called? Ye, event horizon is great
Can’t wait to see what this new telescope captures!
The question "is the universe finite" can only ever be answered with either yes or undetermined
I do not recommend many videos, but this video will be a must view to the people I know. So well done. Thank you
I've seen most of the videos on this channel but this one made me subscribe. Thank you for being awesome and for sharing your work with us.
Infinite universe (s) or not, goodness matters.
well said 👏
We are insignificant byproducts of this incomprehensible thing we call the universe. We exist now, but crazy to think trillions of years will pass after our deaths.
@@terrellwiley3646 it’s terrifying yet inspiring at the same time. Isn’t it!
@@aljohnson3717 It's just sad.
@@aljohnson3717 It makes me think that if everything I do will never matter in the end, makes me think everything we do from every breath of air we take matters all the more.
Thank you really for making these and keep up the great work.
I grew up watching and reading Carl Sagan. You are far and away above his ability to explain the universe . You have honestly presented questions with true scientific curiosity without bias. I read a book by George Gamow entitled ONE,TWO, THREE INFINITY. The book opened my eyes to the world of science. Your videos are much like that book
I love ALL your videos. Your explanations are extremely good in that anyone can understand the complex concepts and phenomenon you're covering. Thank you
"Humanity has had to swallow another great demotion". This statement is an idea that everyone needs to be comfortable thinking about and understanding. Deeply profound, thank you for putting the idea into these words. Subscribed.
A delicate balance between that concept and not falling into nihilism.
This is the best explanation of space/time, factoring expansion, that I have ever seen!
I'm showing everyone I try to explain it too, lmao.
Took me until my mid twenties, when I started asking the question, "Wait, where is the middle of the universe", that dove me down a rabbit whole rediscovering my understanding of the universe. :)
wow this video was that and so much more. thank you. Been watching your videos since I discovered you only a little over a month ago. This makes you one of my top favorite YT content creators. :) infinite kindness to others. I had envisioned that when we die we are just born again into a similar experience but we live out different choices.
-"Unimaginably distant", seems to encompass such an endless capacity for our undying passion, even so, what remarkable peotecism.

Nobody ever thanks me either buddy
I definitely was not expecting to be tearing up when I started this one.
One of, if not the, best channel on UA-cam. Thank you.
....."even the smallest acts of kindness".....This isn't cosmology, it's theology. And it's beautiful. Great video!

not since Sagan have I been so impressed and moved. the combination of science, compassion, and metaphysics you exhibited is profound. I saw you in several TV shows. I had no idea you were capable of this! what a discovery. thank you so much. I'll be on the lookout from now on.
Me too❤️
I agree. Professor Kipping is the next Carl Sagan, so thought provoking.
By just hearing your final message at the end of the video, it was so touching that it made me wonder if it's really possible a person like you were just a product of random chance and evolution. I'm a big fan of observable science and not really on historical science, but in your videos, i am starting to acknowledge some others things that i refused to believe in before. The only question I got left was how is it possible that a single molecule or matter can create life? (from the very beginning of the universe). Doesn’t it breaks the rule cause we all know that life can't come from a non-life at all? The discovery of this DNA thing is a bit confusing too cause according to what I've learned, there is no known observable process by which new genetic information can be added to an organism's genetic code, so how is it possible for a fish to become an amphibian (for example) without adding a new set of information on it's genetic code? as i understand regarding DNA, it is losing information overtime like for example my son has only half of my genetic code and half from his mom and so his own son will get his DNA from son and his wife and so from that it indicates that my grand son will only have like 25% of my genetic information, the same thing happens with my sons grand kids and so on...but there's no way that even one of my great great great great great grand kids will have in their DNA let say 5% from a fish DNA cause it's a new set of information that is different from humans unless someone from his bloodline had sex with a fish which is not possible. what I'm trying to say is even if after thousands of years or even let say millions of years, i can be confident that being a human being, my offsprings DNA code will always be of a human. (not unless the world will get too advance that scientists learned to breed humans with other animals, with millions of years it might be possible) but like i said, i only believed observable science and only those proven by the science that we have now, and also I'm talking about the past where science is supposed to be less advanced. Don't get me wrong but i don't consider aliens as well for that also has no solid evidence yet, i'm just basing everything with the science that we have now just like you. I hope you'll a video regarding this topic in the near future cause it will be really helpful maybe not only to me but for others who also loved your videos. And to everyone reading, if ever there's something here in my comment that is wrong or in any way offended you, i am sorry but it's not my intention, this is just based on what i have learned and my own opinion, I want to learn more so just feel free to correct me if I'm wrong..thanks and have a nice day to all..
Damn, I love your videos. You capture the sense of awe & wonder that keeps me glued to the screen.
I can't stop watching your vids in the middle
The thought of our loved ones still being out there, makes me so happy 🥲
I really hope that is the case, that way my grandad wouldn't have passed from cancer and my uncle wouldn't have a brain tumor. 😭😭
I hope they think of me as often as I think of them. ❤❤❤
Imagine every dream you've ever had was actually a view of something that actually existed and was happening in another universe.
Also have been believing this theory more and more as I get older.. some of these dreams I remember because I need to and others fade away because they don’t want me to find out something just yet.
Also I believe that when you have deja vu, that’s another “you” dreaming in an alternate universe but is dreaming through the eyes of your wake state.
Well... if the universe really was infinite there will inevitably be an exact copy of your dream happening somewhere out there on a planet exactly like on your dream
That would be scary for the other universe because I have nightmares sometimes.
This is existential poetry. Very, very well done.
Some people have existentialism....this gives me hope, and fills me with curiosity. Thank you ❤
:) all the facts you point out, i already know since a long time. But you connected them in a ways that truly give me some goose bumps. Without offence but I'm not a fan of religions, but the last 5 to 10 min....if the people you love could be somewhere still alive.....this has a touch of magic. I really don't see the need for a special book to feel wonder and magic. Its already all around us:) ......but please guys, that is just my opinion...no reason for comment wars ....have a great day:)
No
Very interesting thought, isn’t it. Maybe one day.
I was kind of feeling low but after watching this I realise the choices are truly infinite with a lot of possibilities, and it improved my mood a lot.. It was a great video thanks ❤.
It’s most likely that way but not confirmed.
"What else is out there?"
Me, instantly: "Theres literally EVERYTHING out here, Morty!"
Insignificant, I feel this so much with this video. We are not in control of our own lives, never have been. It was all written when stars were born and cosmic dust with the basic elements came together to ultimately put us here. All energy is where the universe put it and we are all just carrying out the will of the stars.
