The World is Like Grains of Sand in a Vast Vacuum Ocean
(Хмельницький : ПП Заколодний М.І., 2023-12) Preigerman, Lev
The Universe is made up of stars, the distances between which are much larger than their sizes. In this sense, it resembles a gas in which all its particles (stars) and their aggregates (galaxies) are very weakly interconnected by gravity. The density of this gas is small, but it is still significantly greater than the density of vacuum, and their gradient is balanced by the average gravity. If, as a result of fluctuations, the Universe increases slightly, then the average value of gravity will decrease, and the density gradient will remain practically unchanged. This will lead to a further increase in the size of the Universe, etc. Many stars behave in exactly the same way. Our Sun, for example, in 2 billion years will expand to the current size of the Solar System. For stars with a mass of 1.4 solar masses or more, this expansion process is so intense that they explode like supernovae.
