"Students don't learn "opposing" methods for how gravity operates in physics class."

Really? And just how does gravity operate?

And just how does gravity operate?

The best explanation that I've heard -- and the only one I'm aware of as being taught in public schools in any form -- is that gravity is a direct result of a warping of spacetime. Exactly why that warping occurs isn't exactly well-understood. Gravity isn't exactly very well-understood, unlike evolution.
