Nobody knows for sure what is or isn't possible.

by definition, you can't go faster than something that has no mass

yes but current physics models don't support it yet...

Unknown really. We know only a fraction of what exists or what may be "possible"

Body light signalling wouldn't work without protection. You would need to be on the same trajectory as gravity working itself out from a distance, which is the secret of aliens traveling. It doesn't work itself out locally.

There simply are no trajectories in spacetime corresponding to 'faster than light travel'. The notion of faster than light travel is genuinely a confusion about what words mean (assuming general relativity is correct)

There's no way to accelerate all the way to light speed, let alone past it.

Yes, according to current understanding of physics. But you know... never say never

You can still reach far away places really fast with a sub light engine close to light speed, it's just that you'll be forever gone for the rest of us. It's not a big issue imo, most conquistadors never went home either.

how fast are two objects moving opposite directions at light speed

Negative mass would do it. Not anti-matter, but negative mass. This in no way makes the problem any simpler or more achievable. I can only show the way; you must walk the path alone. Cause negative mass will probably give you cancer and turbo-diarrhea.

Does it matter? You can still travel as fast as you want from your own perspective https://www.youtube.com/watch?v=cEkozf-zCkY

Never say never, but I doubt we'll see any kind of breakthrough in our lifetime

faster than light travel is the same thing as time travel

Galaxies are travelling away from us faster than light right now!

From our current understanding, most likely not. Whose to say though. Stranger things have happened.

It's impossible to accelerate an object with mass to the speed of light.But you can theoretically reach a point in space faster than what light would have taken in a straight line.

Instead of traveling faster than light, you should travel shorter than light.

your soul operates at a frequency faster than light, that's why you can't measure it.

yes, thats why they increased the speed of light in 2050
