"...I am sure you can find facts in all fairy tales and works of fiction."

I am too. I agree with that.

"...Gravity is caused by electricity."

I don't agree with that, though. How can electricity cause the shape of spacetime? That doesn't even make sense to me. My understanding of Special Relativity is that in the presence of mass spacetime warps. That warping is gravity. Gravity is the shape of spacetime in the presence of mass.
