No, you keep pontificating that energy had a beginning and then citing sources that contradict your pontifications.No. I keep proving energy had a beginning.So there was already a patch of energy before inflation! Again a patch of energy is not nothing.The increase in mass probably seems strange at first, because it sounds like a gross violation of the principle of energy conservation. Mass and energy are equivalent, so we are claiming that the energy of the matter within the patch increased by a colossal factor. The reason this is possible is that the conservation of energy has a sort of a loophole, which physicists have known at least since the 1930s,but haven't talked about very much. Energy is always conserved; there are no loopholes to that basic statement. However, we normally think of energies as always being positive. If that were true, then the large amount of energy that we see in the universe could not possibly have gotten here unless the universe started with a lot of energy. However, this is the loophole: energies are not always positive. In particular, the energy of a gravitational field is negative. This statement, that the energy of a gravitational field is negative, is true both in the context of the Newtonian theory of gravity and also in the more sophisticated context of general relativity.
So, during inflation, total energy is conserved. As more and more positive energy (or mass) appears as the patch expands at constant density, more and more negative energy is simultaneously appearing in the gravitational field that fills the region. The total energy is constant, and it remains incredibly small because the negative contribution of gravity cancels the enormous positive energy of the matter. The total energy, in fact, could very plausibly be zero. It is quite possible that there is a perfect cancellation between the negative energy of gravity and the positive energy of everything else.
Cosmic Questions - Guth: How Does Inflation Work?
You keep proving energy always existed and will always exist with your own sources!
Thank you.
Do you have any scientific background, Ed?
And yes I am a physicist. So you are trying to lie about physics to a physicist, good luck with that.
