I do. He stole his work from Henre Poincare, and as mentioned, you can't apply physical properties to concepts.

Gravity is an effect of magnetism and dielectricity. We can manipulate objects and make them go up or down using electrostatics. Magnetism is a much stronger force than gravity is claimed to be, and it can be experimentally validated by anyone. Warping and bending of spacetime? Heh.

I think it makes more sense to adopt the views of people like Tesla on this basis. He, among others, was responsible for the basis of the AC motor that gave us our electrical grid. He wasn't a fan of Einstein either.
