Big Crunch

The Big Crunch is a hypothetical scenario for the ultimate fate of the universe that is the complete opposite of the well-known Big Bang theory. According to this concept, the universe may significantly expand, thus launching the process of disappearance. This process will be accelerated by the increasing gravity. However, this cannot last forever, and the expansion will end. When the universe reaches its limits, the opposite process will begin. In other words, contraction will replace expansion. It means that all the celestial bodies (meteorites, comets, planets, stars, black holes, etc.) will converge into a single point. Scientists believe that this point could be very dense (extremely compressed).

Heat death of universe

According to the second theory of the disappearance of the space-time continuum, a constant and strong thermal impact will destroy most of the planets. The universe will begin to expand, experiencing relentless gravitational pressure. This will lead to the mass death of stars and planets, which will begin to go out. There will not be enough energy for the birth of new celestial bodies. Moreover, matter will remain only in the form of elementary particles that move chaotically in space. Of course, these particles will collide from time to time, but they will not exchange their energy. Scientists have summed up that all living beings will turn into such particles.

Black hole influence

Scientists believe that all types of matter that exist in the universe revolve in the orbit of black holes. These are the oldest cosmic formations, specific regions of the universe that are controlled by a powerful gravitational pull. It is almost impossible to resist this pull: it attracts any object in the vicinity. The giant pull of black holes is a "vacuum cleaner" that sucks interstellar matter and all kinds of radiation. If a celestial body enters the black hole orbit, it and its cluster disappear without a trace. In the future, these holes will absorb not only the matter around it, but also each other.

Disappearance of time

The possible disappearance of time is the most mysterious theory of the death of the universe. This is very difficult to comprehend, since humanity does not imagine itself outside the time. Our whole life, from birth to death, is connected with the concept of time. It is hard to imagine that time can suddenly stop. In our understanding, it is constant and cannot disappear into thin air. Therefore, it is difficult to assume that time can freeze in one moment. There would be neither past nor future. There will be just one infinite moment. According to scientists, in this case, time will freeze forever, stopping in a single moment like an image in a photo.
