Traveling Back in Time
HTML-код
- Опубликовано: 18 май 2024
- Is it possible to go backwards through time? We travel forwards every day, but traveling back could let us change our past, visit old friends, or manipulate the timeline to our benefit... Although our knowledge of space and time remains incomplete, we can still use what we know to consider possible time machines. But what kind of paradoxes would this entail and how can we resolve them? Join us today on a special journey through time.

My brother was killed on Friday September the 13 last year when he was only 35. A 25-year-old drunk driver going wrong way on freeway crushed his car head on. I felt so raged. I wish I could go back in time to make him stay home that fateful day. Thank you so much for your video. It is a wake-up call for me to not holding to the past, but appreciating every precious present moment with your loved ones, because life is so fragile and unexpected.
We all pass when its our time.happens to us all.
So sorry for your loss
D N I’m sorry for your loss
🙏
I know what you mean. My beloved cat got brutally murdered in 2009. I wish I could go back in time, take him with me to work every day - I actually considered this as I had a fear something like this might happen (it was my stalker who murdered my cat), but then I thought he would be safer at home.
If I could go back in time - I would take him with me to work, turn my house into Fort Knox or preferably move away, make the neighbors aware of the situation, and not leave my cat out of my sight!
Imagine having someone this passionate as your science teacher in high school , class attendance would be through the roof.. truancy would be a thing of the past
I hope he has children. This is the paradox of human reproduction. It often involves the worst of us creating more of us.
He's a great professor
Yeah, I can imagine it. It's called Private boarding school like Phillips Exeter! Buckingham, Brown, and Nichols. There's tons of em esp up here in the Northeast.
Our teachers didn't care enough to be this passionate about the subjects.

I keep revisiting this video almost every day since a year ago.
My fiancé was going trough tough times and I was too busy with work to see her, She committed suicide One evening at 6pm, I remember exactly the moment and I remember every word of her last message, If I could have answered her Earlier She would still be here.
I was always too busy Working I never considered she would commit suicide. She was the most kind and Cheerful person I have ever meet, she was always looking for a way to help everyone. Maybe It’s not possible to go back In time, But I will never stop looking for a way to go back. Or at least have one minute to talk with her again.
Thank you for this beautiful video.
You should realize that eventually she would have done it anyway, stop blaming yourself. People with suicide tendencies just look for an opportunity but their mind is already made up most of the time.
Do you really think that one message from you and all of her depression and dark thoughts would have disappeared like they never existed 🤦♂️
Sorry to hear that she did this, I can't imagine how tough it would have been to go through and my thoughts are with you.
Hope you can find peace. Im sure she would want that. So sorry man
@@boltzmannbrain6607And what's saying one phrase wouldn't have that impact? it's entirely possible. Or maybe this situation is more nuanced than you're implying? 🤔
You come off very douchey in your comment btw.
@@butHomeisNowhere___ youre dumb. He is blaiming himself which is wrong. Its not his fault. Thats all I was saying
Stop being slow
Such a beautiful, yet haunting video. I really miss my wife, but I push on and try to live my best life for our daughter that she left behind. Luckily I guess my daughter was young enough that it didn’t hurt her as much as it could’ve.
would you not have wished your daughter spent more time with her mom?
I'm so sorry for your loss. Your daughter is lucky to have you in her life. Be strong friend, for her.
@@beyondspace64 Sorry for your loss.
@@tomriddolls5301 What an insensitive question. Of course the man wishes that his daughter could have spent more time with her mother, as that also would mean more time spent as a family, and more time of his wife being alive. But it isn't about that. It's about trying to find some light in a sea of darkness. Even though it definitely hurts for him, it doesn't hurt as much as it could have done for his daughter.
@@lillkrull1161 this is the infinite time loop of life. Some last long, others shorter. And the cycle will always continue.
Oh good, I hadn't had an existential crisis yet today.
palakaman haha that cracked me up!
palakaman
An existential crisis a day keeps the happiness away :)
@@sonarbuge7958 In the long run it's the opposite actually!
Take comfort in the fact that you're not alone in that, we all go through that regularly, I do every day. In this way we're all together in it
@@shivercanada Amen. ;)
Only Dr. Kipping can bring a grown man to tears through physics. Let us raise our glasses...to tomorrow. And today.
i know what u mean, but eyes dont care if you are a grown man
I want to go back to the times before 2012. Back then everyone that I loved lived. Germany was better, the world itself had a different atmosphere.
I 1000% agree with you. Hope you're in good health
i got to go back to july 1 1983 that month my son will be born
i now have what it takes to time travel, what it takes u need a infinite power source for one thing and my infinite power source is infinite light speed which changes reality?
man doesnt have this power but i do now and im going to use it against man
A global repair of globalism........
It's not every day I shed copious amounts of tears watching educational content. As I quickly scan só r of the stories about this videos, my tears intensify....
They add to my perspective, enrich your message and at the same time breeds more questions, triggers my sense of justice and fairness and how the universe and its timeline seems blunt and without prejudice. It plays by its rules without any regard to whom you are.
My sorrows are a drop in an ocean. One that is surrounded by joy and what times does to you is, try to teach you, as you brilliantly portray, if you don't look back, it's invisible and what's in front of you is the joy just waiting for you to walk through it, face forward. That's all there will ever be.
Thank you for being more than a physicist.
Mate the emotional atmosphere you create in your videos is what makes them good, anyone can just state facts but you add weight to them. Keep it up dude!
Thanks!
Good advice
I agree with this - it's one of the reasons I watch Cool Worlds. As a Science communicator - @Cool Worlds does an awesome job at giving weight, and therefore meaning, to the words.
@@CoolWorldsLab *generating a notification* Please see my response to the main comment. :)
@@CoolWorldsLab hi you hit the nie right on the head undo right a wrong of a mistake I made in my life changing the past would change the present casting a wish spell on a full moon if this time portal opens I would walk staght through it right my letter then get back to present save the one what I care about and my self one I can tell you is I sleep on my sette as I was in a deep Fort and as I was partly asleep and partly awake some energy thought me of the sette on to floor it felt like someone pushed me 2022 September 3 2012 I slept on chair and I felt someone walked into me as I woke up in shock I ask me self why did this happen to me something shouldn't had happened thay whay did if I get a chance I would do it in a heart beat 💕🧭🧭🌕
The message at the end of this video is heartwarming to say the least.

I just replied because why not?
yeah it was like WOW
@K C Jones it's a sad & beautiful world...
And depressing. Very sad and most depressing because it is something beyond our reach. It means we wont get the answers to certain questions that have plagued researchers. There are tons and tons of questions and problems that could be fully resolved and settled and put to rest if we could just go back and visit the past and just SEE how some event played out, not CHANGE anything, but just OBSERVE and study and examine what we see. How many problems and questions that would settle! EXAMPLES: 1. we could finally KNOW how the pryamids were built. 2. We could find out if Moses or Solomon really existed. 3. We could find EXACTLY where Alexander's tomb lies. 4. We could know exactly what happened to the Ark of the Covenant .5. We could learn exactly how and why President Kennedy, or the actor George Reeves died. and 6. Scientists could see EXACTLY what a real T-rex looked like! Thousands of other mysteries could finally be completely solved simply by going back and using our eyes!
This video utterly breaks my heart. it’s beautiful. It’s equally hopeless and profound. Painful, haunting truth. ❤️
Makes every choice, every act, every moment as crucial as the last. Every interaction we have with others- how we treat each other- the choices we make will irreversibly impact all others. Make your moments worthwhile.
They say Astronomy is a humbling profession. the more you know about the Universe, the smaller and smaller you feel, which makes you want to cherish all the memories that you have in this small span of time you live.
I'm in love with physics since i was a kid... My daughter passed away 62 days ago, she had MRD and she went through horrible pain during a seizure she couldn't come out from.. 8 years old, 8 years of constant pain, in a world so cruel to ppl with a disability... While she was with us i kept dreaming about changing the course of time so she can be living normally in a different time line, that idea made me ease up a lil bit thinking that Sasha will be playing in a different universe. She's gone now, could've we stopped that, her mom and i? No...
Should we accept she is gone? We can't... Will there ever be a time we can go back and reconstruct our future? Crazy thoughts, i just wanna see my daughter again
Dear ,kinanatto257; I'm so sorry for your loss.. I can sense your level of longing to see her again and even though I may not know you ,I'd help tirelessly to make that happen for you if I could.❤
@@jaymakormik6779 ty Jay for being so considerate... Time goes on bur my friend, pain remains
OMG I’m sitting here balling my eyes out. I hope you are ok, god this life SUCKS SO BAD!! Nothing more except heartache
@@johng1758 no I'm not ok to be honest. Like my life ended when she departed, searching for her even though I know I won't see here again here. I was an atheist and now I'm praying to god to make me dream about her every night , praying that i see her in the afterlife so we could stay together forever.
Came for the science, stayed for the existential crisis.

@J. Angel. You won the comments section !
Each of your videos is a *master piece*
Lets not pervert the word masterpiece here. He does great work. For it to be a masterpiece it has to influence the path of mankind.
Agreed
The BEST Videos ABOUT SPACE, VERY UNDERSTANDABLE...
Sans Handlebars well aren't you billions of years of Darwinian pettiness rolled into a tight ball that i wish you could insert into your own rectum ad infinitum... master piece may have been intended to have alternative meaning to masterpiece you insanely arrogant master bator... i agree with the OP and would add master space to the accolades for this channel 👍
this is one of the best channels i have ever found on here
Not to sound petty but ya... everyone is free to have an opinion, but it's my understanding that a "masterpiece" is any individuals best work at that point in their life. Usually we think of masterpieces coming when an artist or creator is older... because at that point the work is a culmination of years of experience and learning what worked and didn't. A picture of a purple and orange elephant dancing on a swing set is a 5 year olds' "masterpiece" because it's the best they have ever done till that point and don't truly know if it will get better or improve in the future at that present time.
Either that makes perfect sense or I'm stoned as fuck and it's 1:38 am...fuck it, it makes sense to me. Basically what I was trying to say is let people call it whatever they want. I hear music on the radio everyday that apparently is made by "talented artist"...see how that works? (The music is very basic and the singers have so many filters on their voice to make it sound good it literally is the opposite of talented)
Imma shut up now. Enjoy the fucking video/channel... it's hella enlightening or sum shit 👁️👄👁️
Im utterly hooked on this channel. Its rather nice to be educated by a professor this passionate and refreshingly humble.
Life-long learners can appreciate the knowledge backed up with the data,facts,grafts,visuals,🎯on point
Times lack of mercy is a gift...and so is this channel imo. 😊
Cheers James!
True. This material has brought me to tears a few times. It's all so mind blowing, matter of fact, and well presented.... 🤦🏾♀️ I fangirl every once in a while.
Time's lack of mercy is a double edged sword
This is a disgustingly underrated channel
Yeah it is!
Looks like it is starting to pick up though
It just shows intelligence is rare.
my grandmother passed away 3 months ago :' i want back to the past to fix everything and spent time more give more hug to my grandmother :'
I love how this guy can explain science in a dramatic way 😊
This video is truly a masterpiece. I’m brought to tears ever time I watch it.

"Forgiveness Is Giving Up All Hope of a Better Past." - Unknown
That's kind of stupid is my first my initial feeling but I don't know whatever man too many of these videos today brain hurty
This is really enlightening as I think more about it....
Unknown bc it's absolutely retarded. That's like the kind of thing you forget as soon as you hear it. Like it's almost a cosmic paradoxical contradiction period but really it's just stupid to shed all pretentions. Very cute cat though in your picture
@@adarsharao not really my first impression was that it was numb but I gave it more thought, mostly cuz of the kitty in the picture, but I didn't want to judge too harshly and now I see my initial impression was correct it's dumb
@@aaronbradley3232 That quote has been around at least 30 years and with a quick google search, reveals it's been attributed in some variation to a couple of different authors. Just because you don't understand it, doesn't make it dumb.
Very powerful in the end. Live every day to the fullest.
David, not only are you an amazing physicist, you are a great story teller, voice over and creative producer. Multi talented... wish I had you and prof. Susskind and prof. Tegmark as teachers. Keep up this great work.
Your best video ever. Not from the scientific perspective, but from the spiritual.
I can't go back. I can't go back to tell someone just how much I love them. I can't go back to say just how sorry I am, before she walks out of your life. I can't go back and undo what I have done. I can't go back and do what I wanted to do but didn't. Thank you for this video!
"Learn from the past, live in the present, hope for the future"
@Rogue Mentality Your making a comment. Have you gone back?
This channel is SOOO deep
Its philosophical
It’s great to be able to share these with you all, thanks for your time!
The depth of your profound discovery is shallow water for many. Remember depth is a measure of a mind.
Pedro Vazquez its thought provoking. Challenge everything and everyone that destroys the meaning of your reality. Believe it or not the human mind is evolved for this very task.
@@grandmaster-grouch I like to challenge those and that which gratify the meaning of my reality. Shallow water.
This introduction 'Time is a merciless companion...' and 'or perhaps you wish that you could go back and wipe a wrong from your past...to undo a mistake that haunts you every day of your life' gets me to tears every time as I'm sitting here quite educated on cosmolgy and physics yet haunted by so many mistakes from my past knowing I most possibly can't reverse them and having to live with them the rest of my life. Thank you so much for this channel
I can’t fix my life unless this is possible. Hopefully it is
The bartender says "we don't serve time travelers in here. Get out of here."
A time traveler walks into a bar.
Wot?
Lmao, epic x
Ohhh, I like that!
Wait, I dont get it?
Well played sir 👏👏👏
Brilliant, thanks for that!
I almost cried, this topic is so interesting
A really brilliant explanation, as a person it changed my perspective on time travel, it’s really fascinating in addition to that the most important lesson you should take from this masterpiece is: don’t waste time on regrets, live the moment because it’s already passed.
Anybody interested in time travel should watch DARK on Netflix. It deals with an extremely elaborate time travelling story with bootstrap paradoxes, multiple timelines and multiple universes. It's a criminally underrated series.
Is it on Netflix?
Great to see this brilliant channel growing and getting the recognition it deserves.

I replied to the same guy again because why not?
@The Gunman @Cool Worlds Well, except for the part where the narrator keeps playing with himself instead of getting to the point. Good god, what a disastrous substitute for authentic content. Meanwhile his newsreader's emphasis on every second or third word is simply appalling in its brainlessness, a robotic substitute for marrying deserved emphasis to meaning.
You've explained the subject matter in a way
so unique and mind blowing. And for that, I thank you.
I agree. It was beautiful and true what he said. Move forward to new discoveries!!!
A thing that i love of all your videos is that they are not just filled with science, but with poetry as well... This makes them so fascinating and effective
This guy is so eloquent and passionate about science, he makes me want to go back to school and start learning something... I don't even fully understand what he's talking about, but he inspires me... Thank you, my bro bro!!!!
How in the hell does anyone get this smart? I love this channel because it makes my head hurt!
Passion. What are you passionate about? I’d love to hear :)
The last 3 minutes really hit home for me. Live your life to it's fullest. Live, Laugh and Love.
Thank You Dr. Kipping for your lovely videos. I've lived for 70 years and marvel at learning something new every day! Ronald. Orlando, Florida
One of the most underrated channels! 3M subs will make me happy!
Ok I've absolutely fell in love with your channel....please keep uploading...please...this video helped me so much
Does this actually work
His voice and background sounds he chooses are the best meditations of the century
I recently found your channel (I'm obsessed with space so your videos were suggested) and I have to say I'm so glad they were! You take already fascinating subjects like this and make them even better.
Right now I'm recovering from surgery and your voice is so soothing. I've been resting in bed for a few days and binge watching your channel! Thanks for sharing all of this fantastic content! ❤️
You are THEE beacon of light among all the dim-lit dimwit channels! Kudos! My hats off to you!
My best friend and companion( My Chihuahua) had a heart attack 16 hours before this video. I carried him to the hospital. He is alive today, maybe only for a short while longer, and I am truly inspired to not regret the times I did not spend with him but to cherish every sunset until I lay him to rest. My tears are flowing now, but I am better prepared for tomorrow. Thank your Doctor!
Has he perished?
@@jaredgarbo3679 Don’t ask that...
Damn! That was an inspiring blending of physics, logic, philosophy, and every human’s regret and hope. Enlighteningly beautiful and profound!
I felt that I wanted to go back in time to undo anything I did wrong.
I feel that. I would love to go back and fix things, undo all the mistakes I made. Who knows where I'd be now.
@@noshow22 Yeo, lets hope that warp drive stuff they're been looking into takes shape.
@@jaredgarbo3679 looks promising,I think.
The double slit experiment in quantum mechanics shows there is some element of time travel involved for the observation of a wave form causes it to collapse into a solid particle state whilst the prior observation of it being in a wave state is no longer present, as if it always was in a particle state the entire time. The explanation is that the collapsed wave function upon being interacted with and collapsing into a solid particle state must travel backwards in time and then from there go forwards in time to the present time of its observation collapse, but existing from the point of view of the observer as a particle the entire time, like the wave function never existed at all.
It's so hard to find great content that pulls you in and holds you at full attention such as your content and story telling/ narrating does, i truly love this channel and content !
Profound, deep, sad, beautiful. Exactly what I needed to hear today. Thanks man!
I've been watching a few of these videos and the more recent ones, like this one, have a profound lyrical beauty to them. Please keep making them this way.
This guys voice is so soothing I can honestly fall asleep to it.😂
There is one thing we can do: capture moment(s) in time by write, photograph, film and tell each other, for our loved ones or ourselves in the future.
Professor Kipping your videos are so damn clear and easy to follow. High density of learning/connections per minute. Make more :) :)
I was gonna Say that too 😇
The timbre of the voice, the speed, the tone and above all the simplicity ... leads me to be increasingly interested in the topic. Amazing.
I have only just started seeing/watching your videos. They are breathtaking. You deserve your own series with Netflix/HBO/Amazon etc. I LOVE your work. Thank you.
Dr. Kipping, your work across the many channels I've seen you featured is extraordinary and widely appreciated. I just wanted to say thank you. I often am confronted with thoughts to which I have no answer regarding space, time and our position as humans in all of this. So I come here for the answers and often am left uplifted and thoughtful. In the same way one might feel refreshed after a physical workout, these videos make me feel something very similar.
We may not be able to go back in time, but we can rewind and watch your videos as many times as we like. That's all we need.
Thank you so much for your content. I’m just a tattoo artist and oil painter I was terrible in school with my head in the clouds but have made a good living with my work. I have always wished I knew more about science and the universe. I wish I would have had a teacher like you.....back in time. Take care
Just found this channel recently and currently in the throws of a binge-out! truly amazing content, expertly delivered and just awesome narration style. Props :-)
*throes
I love that you combine science with the heart so artfully.
Professor Kipping,
Sir, I salute you. Thank you for passion and poetic mindset. Outstanding video.
Here here The White Morgan Freeman :)
This is one of the best videos I have ever seen. The message at the end of the video is how everyone should be thinking. The world would be a much better place if everyone thought like that
Simply amazing! Poetic and infirmative. Professor Kipping is a rare talent, scientific and artistic.
19:00 This becomes a staple of time travel in Doctor Who. Once an event is learned of or realized, it automatically becomes a fixed point in time, meaning any attempt to change it causes a paradox that would ultimately disintegrate the time stream. Of course, it's because DW operates on the concept of a singular timeline, as opposed to the theory of multiple timelines.
But that was only the theme of some episodes. The doctor would also say "time can be rewritten". I don't think time travel is possible, but I'm sure it has been a fantasy for as long as humans have had fantasies.
@@mavisedwards As far as I know, the only time The Doctor has said that time can be rewritten was when River sacrificed herself in the Library. The next time that phrase is mentioned, it's in The Angels Take Manhattan.
Amy: Time can be rewritten.
The Doctor: Not once you've read it.
It basically states that if an event is observed in some way, shape, or form (at least by a time traveler), then it becomes a fixed point in time and any attempt to alter its outcome results in a time paradox that threatens to disintegrate the time stream entirely.
@@malcolmmorin Plus when Rose saved, her father I believe? some fucking time terrors came to destroy the timeline
I can't dismiss it because I love sci-fi films that play with it, I love to see more Time traveling movies even if I know it's impossible to time travel.
Wonderful video. Thank you.
Wait, was The Assassination of Jesse James by the Coward Robert Ford really a scifi?
I have yet to watch it, and just wanted to know.
This channel is amazing, love the way things are put into perspective with a logical sense of understanding. Almost heartbreaking at times, but always peaks the interest beyond normal everyday thought while making me question every single detail of my everyday life. I love it!
I can’t get enough of your videos! Can’t believe I’ve just stumbled upon them recently. IMO, you make the finest science documentaries that I’ve ever seen on RUclips thus far. Keep em coming please!
Thank you!
Discovered your channel today, and it's fascinating!
But this one?
Well, there are no words. Just thank you!
I've been procrastinating on something and needed to hear that ending message. Thanks. Think I'll go do it now.
Did you do it?
@@wuckfar7819 I don't even remember lol. Probably.
if you've built a time machine, please save my girl :(
I believe in the multiple timeline paradox
I could listen to him all day long and im the type of person that goes to another video after a minute or two after watching it because i cant listen to people for long periods of time.
Thats right
Mmm.. yes: that voice is quite crack like... 🤤🤤🤤
I always had a love for the idea of time travel. When I was a boy, my friend and I lived near a landfill and created a plan to make a time machine out of discarded mechanical parts....lol Then I heard of Ronald Mallet who was working on time travel. Then one day the idea popped into my head that time travel is not practical because our solar system is not only moving through time, it moves through space, so you would need to know where the Earth was going to be at the exact moment in the past. That would require extreme calculations. You would have to identify a moment in time and a point in space that would allow you to appear in available space. Someone please argue this idea and give me hope again. I just watched back to the future..... like the road would still line up to continue driving.....lol
My husband passed from an unexpected heart failure 4 months ago. I watch this video almost every night to comfort myself-I couldn’t know what was going to happen and I couldn’t have prevented it. Yet, I wish for it daily…because I am human. To wish you could rewind time and to have changed the outcome of a 26 year relationship.
This channel is simply amazing. The way you connect with the viewers while beautifully explaining such abstract concepts is not something I have ever seen before. Thank you
So many of your videos make me cry, in a good way, thank you !
Keep up the great work. I have learned so much from you. Thank you for your knowledge
One aspect of time travel I have never seen addressed in any movie or video is the fact that the earth is moving. It is moving very fast. We are not at the same place in the universe that we were a second ago. If you travel either forward or backward in time, you are going to end up in space! I'd like to see Cool World Lab address this point.
I mean if you have figured out a way to move around in time then I'm pretty sure moving around in space would be nbd.
But in like magic time travel examples such as in Somewhere in Time I can see you having a point
Well Doctor Who actually address this sometimes. The TARDIS stands for Time and Relative Dimmension in Space. Putting a neat little bow on that particular problem. I agree its definitely glossed over a lot thougg
Oh no! Another one of these 'time' videos! I'll be feeling lonely, small, and insignificant in a corner within 29 min I guarentee it! Love, love...LOVE your work sir!
The brain is the most complex thing in the universe. There are only 7.53 billion human brains and you are one of them!
Alden D this is the interaction I’m here for
Thank you so much. I needed to see this video. At this exact moment in time.
Keep up making such wonderful videos! You truly have the gift to communicate scientific knowledge in a very, very beautiful and poetic ways. Watching your videos takes me back in time -ironically- when I was a kid learning about space and time from Carl Sagan. I love your productions !
I’m so glad I subscribed to this channel. So many good videos that give me plenty to think about.
Dark is a show that deals with a lot of these concepts, and is fantastic.
I am an immunologist but I will happily spend the rest of my life, as a student, in his research group...
Beautiful
I'm so glad I stumbled across this channel. It's just fascinating
So someone is in love with Chris Nolan films.
Nolan makes great stock footage material because he's, if nothing else, an excellent cinematographer

Parallel universes would be the best possible way I could come up with for traveling back in time, if we could somehow connect to them. That is what I believe dreams are...I've had dreams that have taken me back in time where there was a different outcome of a past event in my life.
Very beautiful and moving video. I didn't get expect to get misty at the end of a technical discussion of time travel and causality.
Kudos to whoever did the editing, and Professor Kipling's presentation and narration is mesmerising as always. I love this channel.
Thank you ,COOL WORLDS CREW...Your closing analogy made me cry with such contentment in realizing that our moments ,though fleeting, are so precious and significant. I just wonder what's next for life and consciousness...for us.❤ I hope to see you there.🙋♂️
I listen to these videos sometimes before bed. Love this guy‼️
I had somewhat of an out-of-body experience watching this great video.
I too, am so glad to have found this channel...very enlightening! And very well explained to comprehension!
Second video I watched from you. No idea why this channel eluded me in the past few years. You have a beautifully calming way of explaining and talking. Loving what I see so far :)
This is definitely 100% my favorite channel and the best channel ANYONE can watch understand and enjoy... Thanks...
You answered every question I've thought about time space. Thanks for the great video, that hopefully will reach millions!!!
I'm so glad i found this channel before the word gets out.. the editing has gotten far crisper and the narration has gotten more focused. A+
what word ? get out of where ?
I disagree.
Of course, whats your point?
Damn you're a baddie 😘
Everyone, it’s a figure of speech
I just discovered your videos lately and first time I thought that 25 minutes would be too long for me. And now I watch one every time before going to bed. I love listening to your voice and how your explain things. It has something soothing and calming. The use of the Interstellar theme in this video is just brilliant!
This is the best RUclips video I have ever seen. Ty.
Simply amazing. Thank you.
My new favorite RUclips channel. Thank you for the videos. ❤
Thinking about this makes me sad because now later in life and recovering from cancer I really can only look back and wish I would have done some things differently. Everything important to me is behind me...
Hope you feel better soon. Don't give up!
This video along the end of the world video are the most amazing and profund videos I've seen on RUclips, I replay them almost daily, you are an amazing story teller, mixing poetry and science is the greatest combination you can ever have
