When replying to this thread: https://www.physicsforums.com/threads/the-nasa-zero-gravity-flight.927136/
I became uncertain of my understanding of the physics after the plane starts to descend.
What I imagine happens is that your forward velocity would remain constant and you would be accelerated towards the Earth at about 9.8m/s2. The part I am most uncertain about is that since you are isolated from the air resistance in the atmosphere you would continue to increase velocity without bound until you pull up or crash.
Assuming I have that correct my next question is what would limit the velocity of a mass approaching a black hole in a vacuum? I know matter cannot be accelerated to c, so what in physics describes the "terminal velocity" of mass? Is it simply the curvature of spacetime which limits the speed?
