At the speed of light, all matter gains mass, including light, though light has no mass.
so if an object with a substantial amount of mass reached the speed of light, it's mass would become so high, so fast, it would collapse in a matter of milliseconds into a super dense material, that has the potential to become a black hole that will suck up the earth and all things surrounding it.
Now IF you can get faster than the speed of light (which is a physical impossibility) you will be traveling into the future, because time is at the speed of light.
Now what MIGHT happen is we learn how to bend the fabric of space by creating super dense matter, folding the fabric together or ever making a hole through it, so that we can move a greater distance using the same sub-light speed velocity.
