Traveling Back in Time
Переглядів 1,239,035
День томуIs 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.

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!

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 🤦♂️

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

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.

@melloman311 2 роки тому
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 👁️👄👁️

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!

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.

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.

@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.

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.
@mavisedwards Рік тому
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.
@malcolmmorin Рік тому
@@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.

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.
