It’s popular to think of those things as like crazy high G turns but they’re not. You’re just flying in a straight line through space time.
Soooo… Interstellar was wrong with all the shaking of the camera?
Are you on earth or is the ship in space accelerating at a constant rate? Again, there’s no way to tell. They are, physically, the same.
In case of accelerating ship, I wonder what would happen in local frame once you hit/get really close to c. You’d get decelerated out of nowhere? Just as if you hit something?
ah, right. In a ship travelling with c, for someone outside the ship, I turn on the lights and observe the light to travel with c. For that external observer the light from my lamp travels at the same speed as my ship
My mind was already bent! ;)
