I am not a physicist but still I love the subject very much. A thought recently popped up in my mind while studying and I'm still confused about it.
"If a person falls freely he will not feel his own weight"
This is a remark made by the great physicist, Albert Einstein.
So the situation is like
Suppose you acquired some net charge and were sitting on a chair in space and being pulled by the electromagnetic forces rather than the gravitational forces, would you "feel a force on your back" despite the fact that you weren't accelerating?
Similarly, if I took the chair away, would you start accelerating despite the fact that you were not feeling any force?
(I'm assuming here that the net charge on your body is uniformly distributed.)
What makes gravity so special that it does in fact act on all matter (and light) whereas forces like electromagnetic force do not?
I'd be very happy if someone answers this question.
Thanks a lot :)
