The Universe will do its own thing irregardless of what we Humans think and want it to do. We humans can believe or think what we want but that in no way alters the physical reality of the world around us. Some people seem to think that simply by thinking that the speed of light is not a constant, in vacuuo, we can make it go faster. The feeling seems to be that by believing we can go faster than light (just totally ignore Relativity as its flawed) the amount of time a light pulse takes to travel a fixed distance can be speeded up. This is patently wrong. There is no way the beliefs of the person doing the experiment can alter the outcome. Otherwise no two experimenters could agree with each other. In the same way, people think that all we have to do to invent anti-gravity, perpetual motion or free energy is to simply redefine a few terms, that is believe something else entirely as those scientists are just believing the wrong things This belief that science is another belief system, divorced from reality, is then extended. It can then be assumed that anyone who counters the belief system is a heretic or contradictory results are ignored/wiped out. As with all belief systems science must have its priests, high priests and laity. From this is fair to assume that students (the laity) are taught not to question by the teachers (the priests) and they in turn blindly follow founders of the theories (The High Priests). Two things are wrong with this view of science. For one, the great names of science became great by questioning the currently accepted views and showing that they had a better way of describing reality. You only become great in science if you overthrow an accepted theory by questioning it. Science is about constantly questioning and testing accepted views rather than blindly parroting some one else. Second, the Universe really does not care for what we believe. Science is about describing that reality as we measure it. If anyone thinks that anti-gravity is possible try this, believe in it, build a machine based on your belief and jump off a tall cliff with the machine. I think we all agree that the person who does this would be insane as we all know what would happen. Same goes for all the icons of science, free energy and what not. If any of this was possible why don't we see it in the Universe? Because it can not be done. Believing otherwise will not make it so.
