Reply to comment by s1ngular1ty2 in Why FTL travel seems impossible to me from a practical standpoint. Insight requested. by JerryWasARaceCarDrvr

With our current understanding of physics what we know is that we can't accelerate to the same speed as light in vacuum.

What we currently do not know is if it's at all possible for something to travel faster at all in vacuum.

I specify vacuum due to the existence of Cherenkov radiation.

Nothing travels faster than light. There is no known radiation that travels faster than light...

IT IS IMPOSSIBLE.

Cherenkov radiation. Look it up. And understand why I specifically talked about in vacuum in previous paragraphs.

Nothing known travels faster than c (speed of light in vacuum).
In a non vacuum medium, light does not travel at c.
Try studying if you don’t believe what I said.

I don't need to study because I already know it LOL. I ignored you because I knew you were trying to act smart by posting trivia you just learned and thought no one else knew which wasn't relevant to the discussion. No one cares about light speed in a medium in the discussion we were having because it doesn't matter. I'm glad you learned something though! Good for you.
