[DC] What exact force is making Superman fly?

I know he gets his power from the a yellow sun, but when he does, what is propelling him through the air?

Well, he doesn't seem to ruin telecommunications, so electromagnetic is out. Weak and strong nuclear forces are pretty much out. He's not expelling matter, so it's not a simple application of Newton's third law. Gravity manipulation? Would also explain lifting large objects without them breaking, etc.
