Albert Einstein developed what has been called the theory of relativity. It can be expressed by the formula E=mc2. It attempted to explain our three dimensional world and the relationship of mass and energy in the physical world. He spent the remainder of his life pursuing what he termed a unified field theory, work on which is still going on which attempts to explain how time enters the picture as yet another dimension. The following attempts to explain how it does.
What this formula implies is that everything is either matter or energy. The equation can be transposed by subtracting mc2 from each side leaving E – mc2 = 0, or dividing both sides by mc2 we get E/mc2 = 1, where 1 really signifies everything. For these equations to be valid neither E nor mc2 can be zero. We are aware in our universe that matter is decaying. In other words, matter is losing the energy that holds it together. That means mc2 is decreasing and E then must be increasing. For that to be true there must be a parallel universe, revolving in the opposite direction where E is decreasing and mc2 increasing. The only visual parallel one can draw is an hour glass where the sand is flowing from one universe to another and when the sand runs out in one it builds up in the other until it runs to where E = mc2 and then flips (Big Bang) and the process starts over.
There is no way to empirically prove this theory but we do have real evidence of its existence. The atom smasher and the atomic bomb have proven matter can be destroyed when robbed of the energy that holds it together. The application of energy in the form of pressure has proven that matter can be created (synthetic diamonds). Einstein posited that light actual bends giving evidence of a circular universe. The problem is we have never been able, nor will we ever be able to accelerate matter to the speed of light squared except in our imagination, which is immeasurable.
We believe in reality because we can see it, touch it, smell it and hear it. If you cannot see it doesn’t mean it doesn’t exist. Someone with the sense of sight and proximity to the object does. If you cannot smell it does not mean it does not smell because someone with closer proximity can. If you cannot hear it doesn’t mean it does not make a noise, someone with closer proximity or more acute hearing can. If it is mutating to another form you can only imagine it because you have not the other senses to rely on but it doesn’t mean it does not exist.
This theory explains phenomenon that have been observed but implies that both energy and matter have always existed without explaining where they came from in the first place which will always be a matter of conjecture.
