Universe

Almost all physicists who work on quantum gravity state that space-time is emergent, not fundamental. If space-time is emergent, what does it mean? Since space-time could not exist before the emergence of space-time, the emergence of space-time means that there is another layer in the universe below the layer of space-time where there is no space-time, and from which layer space-time has emerged. If two points are in the layer of the universe where space-time is real, there will be some distance between those two points.

In one YouTube comment thread, a person wrote the following:

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."

If it were possible for a human being to be simultaneously present in New York and London, then the distance between these two cities would be zero for that human being. But, for all the other human beings, this distance would remain the same as before.

Part I

Two reasons can be given as to why an entity may be spaceless and timeless:

1) Reason A: If the entity is not within any space and time, then it will naturally be spaceless and timeless. We can also say that it will be spaceless and timeless by default;

2) Reason B: If the entity is placed within some space and time, and if it is forcefully deprived of space and time, then also it will become spaceless and timeless.
