Here it is necessary to clarify one thing - matter itself occupies physical space, but energy does not. We usually perceive energy through its impact on the environment. For example, we know that photons carry energy. However, at the moment to which this question refers, the photon does not yet exist. There were no electrons, no protons, not even subatomic particles.
In this case, we are talking about pure energy before the advent of any physical matter. Forces such as gravitational force, strong nuclear force, weak nuclear force, electromagnetic force, etc., did not exist at that time. The forces of nature are just one of those abstract concepts that are unimaginable in physics. There weren't quarks, gluons, leptons, or anything else then.
There is nothing to prevent the presence of energy in the v=0 state. Not only are electrons, protons, and quarks with positive and negative charges absent here, but there is also no electromagnetic force that determines these charges. Therefore, there is no rule on how these fees should interact with each other.
There is no matter or antimatter, and nothing requires a certain distance between them. No stars, no planets, no gravity. This is an astonishing event that is puzzling and difficult to fully comprehend.
In the embryo of the universe, i.e. only 10 -35 seconds after the big **, we have no connection to the known laws of physics. The energy levels are so high and the temperatures are so extreme that all the laws of physics have lost their normal meaning. Therefore, it is no problem to fit the entire universe into a tiny space or even a total volume of 0 because nothing can occupy the physical space. And space itself, in the form we know it, does not exist.
It is necessary to realize that in the moments after the big **, a unique event occurred that cannot be repeated at the moment. However, until the ** itself, when all energy is concentrated in an infinitesimal space (according to our most perfect theory), nothing occupies physical space, nothing keeps objects at a distance from each other, and nothing keeps objects at a distance from each other. May cause rejection.
Inevitably, we must talk about really unusual initial conditions that have nothing to do with our usual view of the universe or physics. This combination of extreme cases is so amazing that it's hard to imagine what it all looks like.
We can judge the temperature to be 100,000,000,000,000,000,000,000,000,000,000,000 degrees. This number says it all: "Forget everything you know about the physics of room temperature up to a few million degrees." Everything is completely different here. So you can't live by the standards that we think of today, because that's a completely different situation.
There is no doubt that there is only one way to explain this phenomenon: matter does not exist, and the laws of physics and the fundamental forces of nature do not manifest themselves in the way they are now. The more you understand this truth, the more amazing it becomes.
