Hey, Just a general question.
So, I've just learned that the force of Net gravity anywhere in a shell is 0. And the Earth can be thought of as a continuation of shells- like an onion or something. And at the center the net gravity is 0.
But I thought the immense force of gravity is what caused nuclear fusion in the center of stars? Does no force of gravity mean no pressure? After all P= F/A. Could someone help me understand this?
Thanks
