That is a question frequently asked and a very good one. I’m no scientist or physicist but have some thoughts on the question. The Law of the Conservation of Energy states that energy cannot be created or destroyed. This could only mean that energy is infinite or always existing without beginning or end. Physics also tell us that matter and energy are the same or put another way, matter is formed of energy. Einstein’s famous formula E=mc2 teaches that the mass of an object or system is a measure of its energy content. So, can we not conclude that nothing has ever been created or destroyed but merely changed from one form to another?
“Energy cannot be either created or destroyed, it can only be changed for one form to another”, Albert Einstein
This then begs the question, what is the cause or source of such changing? Something had to cause the initial formation of the universe from the ever present energy, did it not? Something is causing the continuous changing of energy formations.
Furthermore, as far as I can discern, energy is non divisible but one. It may form infinite diversity but energy itself is one, is it not? What about before the creation of the universe, (if the universe was ever created). There was only energy apparently singular. It would be impossible for anything to be added to or subtracted from all that is, so I conclude that everything is one.
Add to that the fact that Einstein as well as other prominent physicists have concluded that time and space do not exist in reality.
This can only mean that there is only HERE and NOW. There is no past or future. It also means that there is no progression of events. All events are happening now simultaneously. It also means that there is no space for events to occur.
“…for us physicists believe the separation between past, present, and future is only an illusion, although a convincing one.” Albert Einstein
It is as if a giant map exists which contains every possible event extending infinitely in all directions. We are exploring it with a hand held magnifying glass. As the hand moves the glass, new events come into play but the entire map exists always.
However, something beyond our understanding is moving the glass. We think we are in control at least to some degree but I doubt it. I do not believe any brain ever created a thought. Thoughts flow from beyond. We have no idea what will be our next thought, If we were creating them we would have to know them in advance and we would not be having those we would rather not. We think we choose to move from this chair to the other or to have tea instead of coffee but it is all simply the flow of thought. Yes, I know how chemicals or brain damage alters our thinking or abilities but such does not mean that the brain is in control but very well is merely a receiver being manipulated by the hand moving the glass.
“My brain is only a receiver, in the Universe there is a core from which we obtain knowledge, strength and inspiration. I have not penetrated into the secrets of this core, but I know that it exists.” Nikola Tesla
Einstein never claimed genius but stated that the information simply flowed through his imagination. “Imagination is more important than knowledge”. Albert Einstein
I suggest that we exist as Awareness in an eternal ever changing present moment over which we have no control as the Infinite expresses through a projected duality and we are IT..
