Reply to comment by EmmaKat102722 in Why FTL travel seems impossible to me from a practical standpoint. Insight requested. by JerryWasARaceCarDrvr

Nothing even remotely close to FTL has ever been done before... It's not physically possible...

Its not physically possible yet. Our ancestors probably looked to the skies and said "We'll never fly, thats physically impossible for humans." and now look at us... flying all over the place.

Equating FTL to flying is the worst possible argument and often cited by people who have to clue what they are talking about. A child can fold a piece of paper and make if fly. It is that easy.

We know FTL is impossible and wormholes can not be used for FTL travel. Professors give lectures on this to college kids. It is that well understood at this point.

General relativity hasn't really changed much for over 100 years and it limits FTL travel and how wormholes work.

It's not changing. FTL is impossible.

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.
