>Alcubierre warp drive
It doesn't actually allow you to move through space faster than light, it instead moves the space around it and thus doesn't violate relativity in anyway (which should be obvious b/c the idea is a from a solution to EFEs).
Alcubierre warp drive is a space explorer's wet dream: faster-than-light travel...

>FTL is equivalent to time travel
I don't get this, if I instantly teleport to mars how am I timetravelling?

suppose you teleported to a solar system 100 000 ly away. if you look back you'd earth as it was 100 000 years ago.

instead of just wikipediaing, think of it this way:
Space and time are interlinked, Einstein has proven. We call it spacetime. Time is simply a measure it takes to traverse a distance in space, we can both agree on that as well.
If you can traverse large distances (or any distance, really) instantaneously, then it equates to time travel. Again, this is because space and time are both conjoined. Even if you move at 0.9c, you still have a cap on the amount of time it would take you to get to any place. Breaking that cap would be, in essence, time travel.
i hope this helps u friend

that doesn't sound like time travel to me, you are just seeing light that was emitted thousands of years ago, you are not actually in the past

now teleport back to earth....

I see what you are implying but I don't think it would work like that, imagine you are on earth at time=0, you wait 10 years and teleport to a planet 10 lightyears away, you would see the earth at t=0 because the light that left 10 years ago is just now reaching the planet, but if you teleport back, you would arrive at earth t=10years, not earth t=0.

you'd see yourself in the past
