In physics everything is based on some ancient opinions (axioms). What if some of them are false?
Let us take an example. Newton's First Law of Motion is an axiom.
Is this axiom right? Yes? What makes you think so?
How do we know that an axiom false is? If it is contradicted by facts. In this case the fact is a surprising one: "thought has force".
In the picture above you can see the first ever Thought Force Sensor built in the first ever Thought Power Meter. Thought force and thought power are measurable. But where is your force of thought, if it leaves your heads? This question inspirated the answer you can find in the book entitled SPACES AND TIMES.
It is very interesting, if you want to find the answer of the question "What is thought?", you have to take a giant intellectual travel from the particle to the Universe.
