Could you travel faster than the speed of light?

[YNM]

One can't move regarding the spacetime around him faster (or even, nearing, for non-massless objects) the speed of light. But someone's spacetime can do that WRT your local spacetime... hence why we have the boundaries of observable universe (other than we start from Big Bang).

If you actually want apparent "FTL", bend the spacetime.

It's best to think of it like this......if you were moving on a train going at the speed of light, you would be effectively going faster than the speed of light, relative to the world outside of the train. But relative to inside of the train, the 'counter' kind of rolls over in a sense. So relative to the inside of the train, you would only be moving as fast as you're walking. Seems logical right? Except it's wrong.

We're talking about light, mass and speed here, which involves energy. You reach a point where mass is soo much that it's basically impossible to go any faster no matter how much thrust you have.....and that requirement of energy gets super high long before you even reach the speed of light. I'm not sure your body would even be able to exert enough force to move, even if it could survive the speeds. I think the heat and energy alone would just make soup and break every bond of atom in the ship, including you. high speed = high energy. and that's not even taking into account things like all the deadly radiation and particles you'll be hitting along the way.

I mean even if we could reach the speed of light right now through some magical trick of science, any matter would be incapable of surviving the trip intact.
