Hi Grey

“Yes. It's true that the results of general relativity are sometimes counterintuitive and the mathematics are difficult to understand. However, it's also true that it does an excellent job of explaining the things we see.”

General Relativity is a consistent description of reality but I am not so convinced it does an excellent job of explaining the things we see. A tremendous number of extremely smart people have tried to unify General Relativity with the other fundamental forces or description of nature, including Einstein himself. No one has been able to establish a viable relationship that unites Quantum Physics with General Relativity. The two theories have clashing descriptions of what happens at a singularity.

Also regarding the application of general relativity to describe the expansion of space I have an issue with. It is assumed that to determine what is happening, a sphere of spacetime is wrapped around “us” and with in that sphere the matter interacting with all the surrounding matter creates the curvature of space. Matter curves space and the curvature of space tells matter how to move. The thing is, once one establishes curvature around us, move over a few million light years over and establish another description of space. There is also a curvature but it is telling our galaxy to move towards it. Repeat the same process for the galaxy with a galaxy on the other side equally far away. The curvature of space is telling our galaxy to move towards it, The net effect is to cancel each other out.

If general relativity is correct, (which I believe) it is incomplete. And even Einstein believed that.
