As I understand it a vacuum is space that doesn't contain matter, however is it possible to have space that is a vacuum that also doesn't have any energy?
No, there is a non-zero vacuum energy in empty space.dshea said:As I understand it a vacuum is space that doesn't contain matter, however is it possible to have space that is a vacuum that also doesn't have any energy?

The fact of the matter is is that an understanding of quantum simply cannot be conveyed in a qualitative manner of analogy and diagrams. It is a very complex theory expressed mathematically.

In addition, because of Heisenberg's Uncertainty, depending on what you're doing/looking at it can be said that there are virtual particle pairs being created and annihilated constantly thus one could say there is also mass.

The answer to this question is not a simple yes or no. According to Einstein's theory of relativity, spacetime is a single entity that is formed by the combination of space and time. However, energy is what causes spacetime to curve and bend, creating the phenomenon of gravity. So while spacetime can exist without energy, it would not have the same properties and characteristics as we know it.
Energy and spacetime are closely related in the sense that energy is what causes spacetime to curve and bend, creating the phenomenon of gravity. In Einstein's theory of relativity, the presence of matter and energy warps the fabric of spacetime, causing objects to move along curved paths. This relationship between energy and spacetime is essential in understanding the behavior of the universe.
No, energy is not the only factor that affects spacetime. In addition to energy, the mass and velocity of objects also play a role in shaping the fabric of spacetime. Mass and energy are interchangeable according to Einstein's famous equation, E=mc^2, meaning that they both have an impact on the curvature of spacetime.
If there was no energy in the universe, there would be no gravity and therefore no spacetime as we know it. The universe would be a flat, empty void without any matter or motion. It is believed that the Big Bang, which is thought to have created the universe, was a result of a sudden burst of energy that caused spacetime to expand and form the structure of the universe.
The concept of other dimensions is still a theory and has not been proven. However, if we consider the possibility of other dimensions, it is likely that the laws of physics, including the relationship between energy and spacetime, would still apply. Without energy, it is difficult to imagine the existence of spacetime in any form.
