What is a big market?
"Great RIP" is one theoretical way that the universe can end, depending on its overall density, which is difficult to determine. Observation of astronomers and physicists show that the universe, as a whole, is constantly expanding and that objects in it, such as galaxies, move away from each other at a growing speed. If this expansion and increased acceleration continued indefinitely due to insufficient space density, then all objects would eventually begin to disintegrate. In a large tearing, the galaxies, followed by stars and planets, would initially return, and atoms and other particles would tear at the end of the universe. The observations show that it is expanding that bodies in it, such as galaxies, will move away from each other. It seems that the degree of expansion is growing or accelerating, which means that something different from the initial power of the large bang must cause to speed up. This force is generally referred to as "dark energy" or "repulsive gravity".
As soon as the idea of dark energy has been set, the question was raised about how the acceleration of the universe would play over time. The answer to this question largely depends on the weight of the universe, because it determines how expansion could change in the future. If this value is high enough, above the amount referred to as "critical density", then the universe will eventually return to each other, an event called "Great Crisis".
On the other hand, if the density of the universe is too much below this value, then the acceleration does not stop. In fact, it will increase over time and over 20 billion years may occur as a "large RIP". At this point, the acceleration would be such a large Thu objects in the universe would begin to expand.
Great RIP would start with large objects; The galaxies come back and various star systems in them would spread from galactic centers. As the acceleration continues, the stellar systems would tear and the planets would leave their orbit around the stars to spreadIly to space. At some point, stars and planets will no longer be held together and these objects would be torn into particles and atoms. At the end of the large rupture, the atoms themselves would be expanded and disintegrated.
According to recent data, however, this model of the end of the universe is quite unlikely. Although the density of the universe does not seem to be sufficient for a major crisis, it is probably too high to occur a large RIP. The most popular theory concerning the end of the universe is called "Big Freeze". In this model, the death of heat occurs when the universe extends that the transmission of energy is impossible and simple freezes.
