Why astrophysics is all BS

Scientists today still don't know the true cause of the ocean tide or the mechanism of light or the structure of the atoms. How can they know anything true out in deep space?

They thought the tide is caused by the gravity of the moon and sun. Which is a mistake. Tide is caused by sunlight energy circling around the earth westward. 

They thought light travels in space at 3x10^8 m/s. The fact is light coexisting with the matters. Light does not travel in vacuum space.

They thought atoms are formed from orbiting, clouding, or waving electrons around a small nucleus and having 99.9999% empty space. The fact is atoms must have a solidly incompressible surface in order to form into solid and incompressible matters.

Applied physics improved human lives. Theoretical physics is all BS, they use it to scam money and fame.
