Professor Sean Carroll explains how to time travel to past #quantumphysics

[domtgtheonly]

Misleading, it's not a perception phenomenon it's because large bodies affect it's probability.

[seacaptain]

Remember: extraordinary claims require extraordinary evidence. Just bc someone says something, doesn’t mean it’s true. In this case: he’s attempting to explain what’s happening with quantum mechanics but nowhere, literally, does the theory state that multiple universes emerge. That’s his own interpretation and by no means backed by any evidence.

For all you Nerds out there (like me) this is basically the method of time travel used by Avengers Endgame/the MCU and Dragon Ball Z. Any changes made to the past splits the timeline into two or more separate universes.

[peterolivas]

I've always been totally open to this idea. You can travel to the "pasr" of an identical version of your universe. So theoretically you can "change" the time-line but when you return to your "present" you will find that absolutely nothing has changed, because you actually didn't time travel, but instead you went to a totally different (separate) yet completely identical universe. So time paradoxes would be null and void.

The probability of observing a particle at any one point is equal to 0. Therefore I do not see the point of this discussion. At any point in time all you can do is define a probability of finding a particle in some volume. Talking about paralel universes and time travel just based on this is a bit of a stretch to me.

[davetaylor]

Multiple copies in quantum mechanics are particles split 😮

[jeffreychandler]

A very interesting presentation that makes sense of the ideal of time travel to the past. However, perhaps, the Cern Hadron Collider has verified Quantum particles appearing in and out of existence.

[jimmetan]

He explained it so easy to understand but is it correct?

[prisonersforprofit]

loved the original 'quantum leap' show. (1989-93) apparently ahead of its time. but seeing all the doubters in the comments, what the professor is saying is somewhat common knowledge, messing with the past may be a stretch, you may be able to observe it but like 'back to the future', you would alter the future, maybe it simply hasn't been done, so as an atheist all of the sudden a 'creator' comes in to view.

[mrfilipelaureanoaguiar]

I believe there's copies of us but, going to them doesn't mean your clone copie is really you, like on earth it already happens. Now going at a speed that you could think that, you could go back in time by going reverse of the planet or other solar systems would make you go in the past or future. The time you will take will be shorter for that distance, you won't turn older or younger either by turning 5000 times the speed of earth per day, we will see it on earth all those rotations, but, the feeling of traveling that distance may make people think they did more in so much less time that, they think going back in time.

[masterchief]

Dam there's possibility of a universal split.. like atoms have enough energy duplicating every shit into existence lol.

[محمدالمنا-غط]

In other universes I will not be excited dou to the fact that my father made other choices including not marring my mother and his father before him?

[charlesdrury]

My logic tells me no need to go into the past the past would have to be recorded somewhere not like a video recording but like the universe holding all the information of everything that happened in the past that would be a tough one to explain I sure don’t know

[ShawnBriggs]

Could this be done on an organic scale.. where one item or person can be observed EXACTLY as described here?

[andrewjuarez]

It seems that's the reason time can reach eternity.

[mindyourownbusiness-rfhq]

If our existence moment to moment parallels the manner in which cartoons are produced plate to plate, then each moment is not a different "universe" per se but instead a dimension of existence beyond "now" in either




It simply may be the case that higher order entities are interacting with items trap in 3D or 4D. For instance, if a cartoon on a page was alive and we introduce our finger into the 2D plane, what would the 2D figure see? An object that came from out of nowhere popping in and out of existence according to some probability. The cartoon analogy reveals quantum mechanics not not involve multiple universes, but instead, multiple dimensions of complexity, the notion of which our experiences extends only very limited exposure. We do NOT "see" the big all encompassing picture of existence, hence the probabilities of quantum mechanics.🤔

[michaelhenault]

Sounds like a perception problem.

Very imaginative extrapolation 😮

[zahirsadiq]

It correct.. But other than physically

[jaythomas]

In my mind, this makes me understand that when the human body dies you have the ability to do this. I really believe that when the body dies things like space travel, different realities and much more come into play. It’s like a second ability at life

[unknownpwn]

A whole Lotta improvisational explanations going on in quantum mathematics.

What ever happened to conservation of energy?
