Hi
If I had an object and a very long evacuated tube. Presumably the object with only the force of gravity acting on it would continuously accelerate and hence would have no terminal velocity.
However we know that it cannot go faster than light.
If my long tube is say pointing towards the centre of the Earth, how long would it have to be for an object to accelerate up to this speed.
If an object were to be released at infinity in a universe with only one planet would it reach the planet with a velocity equal to the escape velocity or would it have reached the speed of light.Any
thoughts to help my thoughts greatly appreciated
