Einstein postulated that the speed of light had the same value in relation to all inertial observers. This statement caused strong protests from many philosophers, since Einstein's idea was considered as an absurd philosophy, and not physics. The history of physics shows that very often has many failures to confirm a postulate been regarded as a negation of the postulate, and sometimes even as an evidence of nonexistence of a concept. Such conclusions are illegal in a scientific perspective. However, in our daily life we can often be forced to act in this way, in our fight for survival. In this article we see that many empirical results can be interpreted in new ways. As a result of new interpretations of results, even before Einstein, basic concepts can be changed. Light, gravity, inertia and Big Bang can be considered from a new perspective. The wave or particle confusion can be explained and light can be explained without quanta of light. The photoelectric effect is observed with the help of discrete electrons producing quantization. We can therefore not conclude quantization to exist before detection. Einstein's quantization of light is therefore a postulation only, and not a logical fact.
