The fundamental mistake in physics is the theory of atomic structure. 

Gas and liquid cannot make any solid incompressible object. The atom must be a solid incompressible building block of solid matters.

Soft LEGO pieces cannot make solid toys. Atoms must be packed together to form liquid and solid matters. The contact area is on the surface of atoms, therefore atoms must have their incompressible solid surfaces in order to form into incompressible solid matters. The electron shell, electron cloud, electron wave, electron orbit, in the present theory, are not solid. 

If atoms are formed from electrons orbiting/clouding/waving/whatever around a nucleus, what is the precise mechanism?  How can atoms be an incompressible and solid object?

If 1 electron and 1 proton can form into a stable hydrogen atom, what is the structure? How electron orbits/waves/clouds around the proton? What is the precise mechanism? Why electrons and protons don't stick together under Coulomb's force?

If carbon atoms are made from 6 electrons waving/clouding/orbiting a nuclear and having 99,9999% empty space, how can diamond cut glass?

How atoms emit light? What is energy?  How atoms carry energy? What is the energy level? How electrons flow in the conductor? Why electrons don't flow to the positively charged nucleus?

Theoretical physics is a religion. Deniers are foolish.
