Wave Function

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."
