EINSTEIN POPPER AND THE THEORY OF LIGHT AND MATTER discusses under philosophical logical and
mathematical aspects the theory of light and the problem of explaining gravitation one of the
oldest problems of philosophy and physics. Assuming the cause of gravity to lie in a force of
attraction without a material agent would violate fundamental principles of physics. Newton saw
that and he knew that his theory left gravity well described but unexplained. Michael Faraday
also saw the problem but could not solve it. Both relied on the ether hypothesis which was
given up at the beginning of the 20th Century in favour of Quantum Theory and the Theory of
Relativity. Quantum Theory and the Theory of Relativity however rested on serious logical and
mathematical mistakes. Max Planck gave no reasons for the individibility of the quantum and
his quantum jump assumed velocity without taking time. Einstein based his theory on a
mathematical self-contradiction that remained undiscovered in a whole century. Both theories
must be abandoned.In that difficult situation applying Karl Popper´s theory of science leads to
a revival of the ether hypothesis in a different shape. If matter is not distinct from ether
but is itself a process composed of ether particles then their elasticity will explain the
phenomena of light of gravity of the stability of matter of the vortex shape of galaxies
and several other phenomena as well.
