David (its that man on the rock lol) asked the Naked Scientists:

What force keeps electrons and protons apart in an atom? Does gravity play a role in this?

Mind you, if the perception gravity is based on the warping of time, would time itself inter-act with the electrons/protons and other sub-atomic particles to created the distance away from the nucleus of the atom????
What do you think?

Gravity is so weak compared to the electric forces in an atom that it can be effectively ignored.

This topic has been dealt with extensively in another recent thread: http://www.thenakedscientists.com/forum/index.php?topic=68158.0

The Coulomb force (aka the electric force). See: http://scienceworld.wolfram.com/physics/CoulombForce.html

No. It's not meaningful to speak of time interacting in the way you mention.
