What I'm telling you is that acceleration is change of velocity
which you've confused with force, childish dingbat.
You've been listening to that moron Einstein and his Principle of
Equivalence, haven't you?

Can't be, I move in the spacecraft relative to the ground.
I do not move relative to the ground while sitting in my chair and
the Earth is quite definitely not expanding.

Perhaps you do not understand the concept of movement.
It is not equivalent to staying where you are. The station
comes to the train, the WHOLE universe minus one spaceship
moves in the opposite direction to the ship. I am ALWAYS at
the origin of my system of coordinates, I cannot be anywhere else.
