00:00Time travel is still very much science fiction, at least to us layman's.
00:07But in the world of physics, that's not the case.
00:09However, now a new theory could change the way experts think about time relativity.
00:14And they say it could prove traveling through time is an impossibility.
00:17Matias Koivarova and two other physicists were looking at how light would slow when passing through a magnetic field.
00:23To come up with their new theory, the team first threw out convention
00:26and used an equation that treated light speed, albeit a constant in the universe, as an accelerating wave.
00:31With Koivarova saying about that aha moment, quote,
00:34The only assumption I needed was that the speed of the wave is constant.
00:37Then I thought to myself, what if it's not always constant?
00:40This turned out to be a really good question.
00:42While that initially didn't make any sense mathematically,
00:44when they decided to use an accelerating wave of something else, say a spacecraft,
00:48against the constant of light speed, that's when everything fell into place.
00:51And despite the equation's new form and novelness,
00:54they say it ended up having the same implications as relativity.
00:58With Koivarova adding,
00:59What we have shown is that from the point of view of the wave, nothing happens to its momentum.
01:04In other words, the momentum of the wave is conserved.
01:06Which means that if the momentum is conserved,
01:08it is not altered in such a way as to be moving in a different direction through time.
01:12And this theory could mean time travel is impossible.
