The author argues that progress in understanding the universe has been held back by misunderstandings. Correcting these and the universe is simple to understand. Einstein's Special Relativity must be scrapped. He failed to define stationary and his use of relativity in his equations was unbalanced. Therefore his conclusions on time and length are not valid. Time is simply a mathematical calculation and cannot dilate. Thus General Relativity, curved space and gravity are incorrect. A quantum solution for gravity exists in boson radiation from protons. (The missing graviton?) The electromagnetic wave is a particle's mass and momentum, and resistance to motion is the time delay for its creation from added energy. A charged particle itself has no mass.
Correct these and Dark Matter and Dark Energy become obvious, including how to produce cheap, clean energy from gravity.
