What is a big crisis?
The Great Crisis is a hypothetical cosmological event, when the entire universe collapses under its own gravity and ends with the singularity of the black hole. The great crisis is a possible scenario for the final fate of the universe, along with others, such as indefinite expansion (great tearing or death of heat), and a great reflection where the universe would collapse, but then unpacked again. Many cosmologists considered a great crisis as a credible result far -reaching for the universe until 1998, when the dark energy was discovered, the mysterious force causing the expansion of the universe that has been discovered by an indefinite extrasement that is currently currently that is currently that is currently. It is currently in its present form, in the course of a current delated that is currently believed in the course of the current delays. billion years ago. After the theory of the Great TThe Řeska became well established and supported by many series of evidence, scientists began to say, "We have a good model to start the universe - what its end?" General relativity, theory was invented by Albert Einstein in 1916, gave cosmologists a mathematical tool for exploring possible end -states of the universe.
The most important variable in the question of the end of the universe and the possibility of a large brunch is the omega (Ω) value, which is defined as the average density of the matter of the universe divided by the critical value of this density. If Ω is greater than 1, then the universe is closed, which means that space geometry can be compared to the inner surface of the ball. If Ω is greater than 1, as V, the space is filled with sufficient amount of mass, then the great crisis is ultimately inevitable. If Ω is less than 1, then the universe is open and will not expand to indefinitely. Recent observations suggest that Ω is less than 1, but this could always changeT with other knowledge.
is a known fact that the universe is expanding. In a large crunch scenario, this expansion would eventually stop, then turned, and the galaxies approached and closer to each other. After a few decades of billions, the galaxy would eventually get so close that the individual supercasters of galaxies would no longer be clusters, and instead they would become a super galaxies. The center of these galaxies would contain massive stars, similar to the population that I existed at the dawn of the universe.
These stars would be so massive that they would drop in less than a million years; A typical life of a star like the sun is more like 10 billion years. In the end, all the matter would be so compressed that it would stop all their lives, and everything in space would be consumed by a massive black hole. Fortunately for our descendants, such an event now seems unlikely.
