+48 According to the law of conservation of mass, it is impossible to create or destroy matter. This disproves time travel as it would violate said law. Sending mass back in time increases the amount of energy that exists at that particular moment, and depletes it at the point in time from which the matter had been sent, thus deeming time travel physically impossible, amirite?

What disproves time travel is the fact that time doesn't exist at all

Just because you live in a subjective universe doesn't mean we can't travel through what the rest of us call time

I'm no physicist, but I thought only things with no mass could travel at the speed of light.

You're right. If time travel were possible we'd need to go faster than the speed of light via Einstein-Rosen Bridge or a singularity. (This is more to OP) There's the exact same amount of matter in the universe, it's just in a different place; no mass would be created or destroyed, it wouldn't violate the law of conservation of mass.

The law of conservation of macs was disproved in the futer when the element was discovered to make the time macne.

The mass will remain constant no matter where it is. If something were to actually "time travel" then none of it's mass would be lost. Time is irrelevant because time is relative to where you are. The higher you are, the faster time is moving. So to travel through time, an object must move faster than the speed of light. But the mass would remain conserved.
