Why relativity is BS?

Relativity is based on two assumptions.

1. All physics laws are the same in the whole universe.

2. Light propagates in vacuum space at 3 x 10^8 m/s.

Einstein famously said in 1954 that after 50 years of research, he has no clue about what are light quanta. Everyone thinks he knows it is mistaken.

The fact is light is oscillating atoms carried oscillating electrostatic force at visible frequency. The light must coexist with the matter/medium, there is no light existing or propagating in vacuum space.

Einstein thinks gravity is not a force but the curvature of space-time. He states that space tells matter how to move and the matter tells space how to curve. The fact is gravity is the most accurate measured fundamental force coexisted with masses. Space-time has no real meaning, no curvature, space can not tell matters how to move, only force can move matters. And matters can not tell space how to curve, space has nothing can be curved. It is all word puzzle, monkey story.

There is no black hole, no gravitational wave, no big bang. All BS.
