Can space/time exist without matter?

No. General relativity tells us that what we call space is just another feature of the gravitational field of the universe, so space and space-time can and do not exist apart from the matter and energy that creates the gravitational field. …

Does time exist within space?

Einstein showed that time and space are intimately linked and that the progression of time is relative, not absolute. Although there is nothing in physics that says time must flow in a certain direction, scientists generally agree that time is a very real property of the Universe.

Does space and time matter?

Space and time don’t exist obviously without matter. But nowhere in universe you can find the same conditions or properties for the space and nowhere is a clock that shows an universe-time. If you could leave the earth, space and time would modify and you couldn’t perceive because you take part on the changes.

What do you call the space without matter?

A vacuum is an empty place, which space nearly achieves. But the vacuum of space is the opposite. By definition, a vacuum is devoid of matter. Space is almost an absolute vacuum, not because of suction but because it’s nearly empty.

What is a space without matter?

Is there any energy in empty space?

So, yes or no, depending on how you prefer to look at it. However what about empty space – it certainly exists. Then there is no matter and hence no energy, and since also there is no matter space cannot be curved so energy can’t be stored in the curvature of space.

Can energy be incarnated as matter?

Einstein showed that energy is matter; for something to exist in a physical sense it must be incarnated as matter. So on the face of it – it seems that the answer should be no.

Does the universe exist if it only contains one electron?

From a scientific standpoint the answer is clearly no. But there are caveats. The whole universe would still exist if it contained only a single electron. But it may not exist (as we know it), if it contained only photons, since photons don’t interact with time.
