I’m obviously no scientist, and I wonder why terminal velocity (120 mph or something) doesn’t come into play here if it’s supposedly “terminal”. I mean, he isn’t using power to drop, is he?

I’m confused. Help!

cheers
Jim

There’s no terminal velocity in space. Thinner air = higher terminal velocity.

I think you reach speeds in excess of TV just by going into a delta position arms to sides.

Terminal velocity depends on air resistence and gravity.
120 mph is only good for 10,000 feet or so.
Terminal velocity from stationary in space is 7 miles per second = escape velocity, which is the same thing in reverse if there is no air.

Terminal velocity is when the forces of gravity on an object reach a homeostatic point with the resistance of the medium that is being traversed. By going to an altitude of 120,000+ feet, he’s hoping to accelerate as much as he can in a virtually frictionless environment where the forces to counter the acceleration from gravity are mitigated.
