Theres a lot of discussion about time in the world of quantum physics.
Think about the clock on the wall.
But things are muchsimplerin the quantum realm.
In other words: time travel actually makes sense through a quantum lens.
Whatever goes forward must be able to go backward.
It’s free, every week, in your inbox.
But under the theory of quantum mechanics, such deletion is impossible.
He, of course, couldnt explain exactlywhereit went.
But most physicists were pretty sure it had to go somewhere nothing else in the universe justvanishes.
What both teams discovered was that a slight change in perspective made all the math line up.
And thats what stumped Hawking.
Imagine a single photon of light getting caught in a black hole and swallowed up.
But, according to Hawking, black holes leak thermal radiation.
And that means they eventually lose their energy and mass and… fade away.
Thats because they were looking in the wrong places.
Hawking and others were trying to find signs ofthe missing information leaking out simiarlyalong a black holesevent horizon.
Unfortunately, using the event horizon as a starting point never panned out the numbers didnt quite add up.
The 2021 New Horizons Prize winners figured out a different way to measure the area of a black hole.
Ive just got this physics theory.
We know that time travelispossible in quantum mechanics.
However, that doesnt mean quantum time travel isnt just as mind-blowing.
Then again, nobody showed up forHawkings party.
So, either it isnt possible or time travelers are jerks.
