I find the principle of Einstein's "Special Relativity" with regards to spacetime to be a "farce". I am well aware of his theory as he published it in 1905. I am also well aware of the fact that the scientific community has since embraced it as a principle of fact. They even call it the "fourth dimension". As if time itself is a "force" in the universe. But after more than 30 years of studying it I have come to my own conclusion. That no matter how you describe interactivities of matter and energy on each other with relation to the velocity involved, time does NOT exist. It is not a force. Hence, the movement for example of people is not possible forward or backwards through "time". The noted effects of one man travelling in space who ages more slowly than say his twin brother who stayed on the Earth during that time is considered a fact of science (this being the effect registered on astronauts who have travelled in space). In my opinion it is not time but rather the effect with or without gravity reacting on matter as it accelerates through the vacuum of space, ...and nothing more. Time is not a constant because it simply does not exist. Events "occur" simply because of the complex effects that matter and energy play upon each other.
Just a thought!
