Matter

1) Physicists have shown that the total energy of the universe is zero.
2) SR has shown that mass and energy are equivalent.
3) Again GR has shown that space, time, and matter are so interlinked that there cannot be any spacetime without matter; similarly, there cannot be any matter without spacetime. There is a saying of Einstein on this: "When forced to summarize the general theory of relativity in one sentence: Time and space and gravitation have no separate existence from matter."

In an earlier article ‘Is the total energy of the universe zero?’1 I have already shown as to why the total energy of the universe would be zero. But there is one deep metaphysical reason that surpasses all the earlier reasons, as to why this total energy can never be other than zero.

In another article ‘Existence of anything can ultimately point to God’2 I have also shown that if anything exists at all then ultimately there would have to be something that would be neither in space nor in time, as otherwise there would be an infinite regress.

Scientists have found that the total energy of the universe is zero. From there they have argued that the universe might have originated from nothing due to quantum energy fluctuation in a void, no God being needed for its creation. But I think zero-energy universe gives us one more reason for believing in the existence of God.

Recently I have some communications with an atheist.

He has written that there is a magic leprechaun who created the universe. He has also written that he has evidence for it, because he has a book which says so.

So I have to ask him as to whether his magic leprechaun is spaceless, timeless and immaterial, because otherwise his magic leprechaun cannot be the creator of the universe because of the following reason:

It can be shown that the total energy of the universe would also be zero if it is created by some supernatural agent. Let us say that this supernatural agent is God. Now what does it mean that the universe has been created by God? As universe primarily means its space, time, matter and energy, so universe created by God will mean its space, time, matter and energy have been created by God. That will further mean that before creation by God there was no space, no time, no matter and no energy.
