Is gravity not actually a force? Forcing theory to meet experiments

One of the arguments is they responded to acceleration and gravity pretty much the same way as conventional matter. Now I'm told it is massless. <shrug> OK, whatever.

:D
All current theories that I am aware of still assign mass to photons ( and/or e and m waves ) Just no rest mass. The biggest change that I have seen is that the neutrino was thought to have 0 rest mass and is now believed to be small but non-zero.

And since GR gravity has not be a force, but an aspect of curved space-time.

The same book argued that gravity and acceleration were aspects of the same thing. Put a person in a box on the surface of the earth, or accelerate them at 1G and there would be no experimental way of telling the difference without looking outside the box.
Wouldn't the potential discovery of the graviton throw a wrench in that?

Maybe, but since they haven't it is a moot point. This is a thought experiment supposedly dreamed up by Dr. Einstein. If you can't tell the difference between two experience, they have something fundamental in common.
