To make the absolute vacuum of 0 Kelvin we need an extraordinary energy that is obviously higher than the gravity. within some time the absolut vacuum will be destroyed naturally by the gravity or maybe the Absolut vacuum would stop the gravity source from spinning and thus destroy it.
Since we detect nothing from the absolut vacuum.We can only observe the state before the absolute vacuum is made in the experiment , and the state after.
To make sure we have the absolute vacuum ,we should expose its area from one side to the most energetic radiation discovered in the nature(frequency and amplitude) and make sure from all the other sides that it disappeared. If we discover in the nature a new radiation with a higher energy than we will automatically discover the more absolute vacuum :p
The internal energy+All potential energies of a stopped material object( without a Kinetic Energy) = the energy needed to make this object lonely in the absolut vacuum of 0 Kelvin where nothing can move.
1) Kelvin is not a pressure unit, 0K is unreachable according to the Nernst-Simon statement which is a predecessor of the third law of thermodynamics.
2) Every substance has some sort of vapour pressure, so the minimum pressure that could potentially be reached technically is the vapour pressure of the chamber material at the given temperature. Realistically, the threshold with the existing pumping systems is higher, though, so probably interstellar void pressure is still the lowest pressure known to mankind.

As you know, the pressure is made by the movement of particles. However, the 0 Kelvin is the only temperature where all movements stop. Or is there other temperatures where all movements stop? Will we discover temperatures less than 0 Kelvin one day ?
Of course the absolute zero would be the point at which all motion would stop. There will not be temperatures less than 0 K because then the whole concept of temperature would stop making sense.
About the unachievability of absolute zero, there are different arguments I've heard over the years. The one I personally like the most is based on the aforementioned Nernst-Simon statement. The entropy change is calculated by the integral of c/T in which c is the heat capacity. From the development of c/T near absolute zero you can derive that the energy required to cool even further diverges, so you could draw a sluggish analogy to accelerating something to the speed of light: you can always come closer, but the energy requirement diverges.
There are also other approaches to this, but they essentially are different ways of formulating the same thing.

-1/0; to 1/0; are natural limits of values with the center omitted.
I think that the only possible absolut vacuum is the one observable in Space or near an Event Horizon. What do you think ?
No, even space vacuum has some molecules in it. It's five orders of magnitude lower than in our best vacuum chambers, but it's still a finite pressure:

Jürgen Weippert , Don't you think that in the absolute vacuum, there should be no Gravitation energy?
What does that have to do with anything discussed up to this point?
But for the sake of having given an answer: I do not see why there should be no gravity there. As long as masses exist somewhere, even remotely, gravity will also exist. There is no "gravity ether" required to "transport the force" so the lack of matter in your probed location doesn't change anything.
Jürgen Weippert ,
We could make an environment with no Gravity for astronauts training. So my proposition is to create the same environment with no Gravity before creating the vacuum and let's measure how much energy is needed for that in 0 Gravity.
What do you think ?
There may be a point in the universe at which the whole universe pulls in all directions with the same force. I'm pretty convinced that this point is not on earth, therefore this would make nice hypothetical question for an exercise sheet, but I don't see any connection to anything real that could happen on this planet.
A new experiment could make a vacuum-sealed environment of 0 Kelvin but far from Gavity. The Bose-Einstein condensate could be observed for a few time. Is it the 5th form of matter?
Here is the link of the article: https://bigthink.com/hard-science/bose-einstein-condensate-in-space/
The "first time observation" of a Bose-Einstein condensate has already happened, unless this article has been proven wrong:

PS: please finally stop using Kelvin as a vacuum unit. It's wrong, it's just wrong.
