Time travel is still very much science fiction, at least to us laymens.. But in the world of physics that’s not the case. However, now a new theory could change the way experts think about time relativity and they say it could prove traveling through time is an impossibility.

00:00time travel is still very much science fiction at least to us layman's but in the world of physics
00:08that's not the case however now a new theory could change the way experts think about time
00:13relativity and they say it could prove traveling through time is an impossibility matthias koivarova
00:18and two other physicists were looking at how light would slow when passing through a magnetic field
00:22to come up with their new theory the team first threw out convention and used an equation that
00:27treated light speed albeit a constant in the universe as an accelerating wave with koivarova
00:32saying about that aha moment quote the only assumption i needed was that the speed of the
00:36wave is constant then i thought to myself what if it's not always constant this turned out to be a
00:41really good question while that initially didn't make any sense mathematically when they decided to
00:45use an accelerating wave of something else say a spacecraft against the constant of light speed
00:50that's when everything fell into place and despite the equation's new form and novelness they say it
00:55ended up having the same implications as relativity with koivarova adding what we have shown is that
01:00from the point of view of the wave nothing happens to its momentum in other words the momentum of the
01:05wave is conserved which means that if the momentum is conserved it is not altered in such a way as to
01:10be moving in a different direction through time and this theory could mean time travel is impossible
