The biggest mistake in science is the standard model of atomic structure theory.
The theory says 1 electron and 1 proton can form a hydrogen atom. This is impossible.
There is only an attraction force F=Ke x re/R^2 existing between those two opposite charged particles, the only motion possible is an acceleration toward each other on a straight line and collide. Assume basic particles are indestructible solid balls, according to momentum conservation law, the two particles will bounce back and forth forever. The electron is impossible to orbit or wave or cloud the proton to form a stable atom, there is no such mechanism. If gravity is as strong as electrostatic force, the whole universe will become a big star.
The theory says atoms are 99.99% empty space. This is impossible because the matter is not 99% compressible.
Why those simple facts are not in textbooks? Because science is still controlled religion.
Before we truly understood the atomic structure, we can not understand the universe, all theories are just theories.
The second mistake is the light speed in vacuum space is 3x10^8 m/s.
Relativity, QM, cosmology are all based on light speed in vacuum space is C.
In fact, light only exists in matter/air/water/medium, there is no light, no photon or EM wave traveling in space at light speed. Light only exists in hot plasma on the Sun and atmosphere on Earth.
Energy must coexist with the matter. Light induces light instantaneously throughout space due to the universal repulsion force/levity between the line of sight electrons on the surfaces of all matters F=Ke x ee/R^2. Light propagating in the medium at light speed. Light speed is the rate of induction of electrostatic force in the medium.
We can measure light speed in a vacuum glass bottle using MIT 10 trillion frames per second camera to prove light speed in a vacuum is infinite.
But no scientists will do it. The fact that light speed in a vacuum is infinite to scientists is equal to their God is fake. The whole modern physics is based on light speed in a vacuum is 3x10^8 m/s.
All these fifty years of conscious brooding have brought me no nearer to the answer to the question, 'What are light quanta?' Nowadays every Tom, D i c k and Harry thinks he knows it, but he is mistaken. -Albert Einstein 1954
There is no photon particle existing. Light only coexisting with matters, there is no light, no photon, no EM wave traveling in space at light speed. All scientists are wrong.
