Physics is the ultimate death warrant for the universe?
Physics is the ultimate death warrant for the universe?.
Time is an illusion:
Our naive perception of its flow doesn’t correspond to physical reality.
Even albert einstein’s relativistic space-time — an elastic manifold that contorts so that local times differ depending on one’s relative speed or proximity to a mass — is just an effective simplification.
Time travel is the concept of the wormhole in which you go backwards view you loop through something and you go back to another not just a different place in the universe but a different time in the universe so that may break some causality laws of the universe so we are not sure how that works
Stephen hawking had proposed that it
May not be allowed
Because it breaks causality but it is
Just a conjecture we don’t have proof of
So wormholes would be the best way to
Travel back or forward in time
So my point here is, that even though,
As we’ll see today,
That even if time travel is most likely impossible
Due to our best understanding of physics,
Our best understanding has been wrong,
So this is another attempt at trying to get something
That gets us time travel to the past.
And the idea here is, are you have a very dense material
And if it’s rotating fast enough and the material is dense enough
This twists space-time in a way that travelling around in space
Should get you back in time.
If time travel’s real,
Forget about the paradoxes of killing one of your ancestors,
Either by accident or on purpose,
But what happens if you have objects or ideas
Without an origin that is essentially closed loops?
So this is very, very, very bizarre.
So one solution, by physicist david deutsch,
Is that – you’ve probably heard of the solution of parallel universes.
Oh, there are no paradoxes, you just make another timeline.
Another explanation is predestination:
If you try to assassinate hitler, your gun will always jam.
I think that’s a lousy explanation;
It’s not intellectually satisfying.
Then there’s a third explanation that’s not explored,
Very often not even in fiction, because it’s so bizarre.
And that is the idea that if you did try to create a paradox,
The universe becomes a möbius strip.
And you have two timelines existing simultaneously,
And so if you go back in time and kill your grandfather or your mother,
You become – you’re both dead and alive,
Like schrödinger’s cat – you’re 50% dead, 50% alive.
The biggest question arose with time travel is, if time travel is possible why haven’t we seen any time travellers yet
So i’m going to boldly declare that time travel’s not disproven
By a lack of tourists from the future.
And the reason is easy.
For example, a wormhole is a classic example of this –
You can’t, even if time travel is real,
You can’t go back before you made the machine.
So if i use a wormhole, for example, time travel,
The day that i punch the wormhole,
That’s the first day i can go back to, from the future to that day.
I can’t go back further than the past,
Then the moment i created the machine or phenomenon.
There are exceptions, of course.
What if there are naturally-occurring wormholes
That has been around since the beginning of time,
Things like that.
But in general, i’m not worried about the lack of tourists from the future,
Because it just means time travel hasn’t been invented yet.
Time is a river
It’s a river that can speed up and slow
Down so that time beats faster on the
Moon than it does on the earth
Timing out of space on a rocket ship be
Slower than time on the earth
A clock on jupiter be slower than
The clock on the earth and we measure it
That’s why we have the gps
And then we can even go one step beyond
The river of time can have whirlpools
Whirlpools in the river of time and can
Fork into two rivers and that allows us
To resolve the time travel paradoxes
When you go backwards in time and meet
Yourself as a child
And you kill yourself as a child
How can you survive as an adult when he
Just committed suicide in the past
This is the grandfather paradox how can
You still be alive if you killed your
Well there’s a way around it
And that is if the river of time forks
Into two rivers
And in one river abraham lincoln was
Assassinated at ford theatre he died
But if the river of time forks
And you jump the stream
And you’re now on this other river
You can save abraham lincoln from being
Assassinated at the ford theatre but
You’ve saved somebody else’s abraham
Lincoln a parallel abraham lincoln
Because the quantum theory allows for
Now the quantum theory allows for
Electrons can be two
Places at the same time
The human brain is a time machine what does that brain do
It creates a model of yourself
It is a time machine
It daydreams it imagines worlds that
It just you daydreamed and got into the third level
Time travel is time travel possible well
As i mentioned einstein’s equations do
Allow for time travel but how stable are
That is when you enter the time
The machine will it blow up hawking thought
So hawking redid the calculation showed
That time travel is possible in
Einstein’s equations but and this is a
Huge but as soon as you enter the time
Machine it blows up
Well it blows up because again of
Corrections did not speculate about them he
Speculated that they are infinite but
Maybe they’re finite in which case you
Can go backwards in time and visit
Yourself as a child
And then perhaps the greatest
Application of all
Is the fact that the universe is dying
Physics is the ultimate death warrant
For our universe
