Can we assume that the Universe has existed forever? If the answer is yes, then it can endure an endless cycle of constant explosions, where all matter is subject to changes due to the signature. The explosions are followed by the phenomena when the entire space of the Universe is absorbed, forming a dense point, and from it the Universe is reborn. And such a cycle can be repeated endlessly.
However, the theory has never provided any evidence to prove whether the Universe is cyclic or whether it has only one beginning and only one end. A group of researchers decided to use the power of string theory to solve some of the fundamental mysteries of the early Universe.
The result of these studies can become the impetus in the theory that is necessary for the Universe to be recreated from the scratch, thereby repeating its cyclicity. A science established that the Universe is constantly expanding. It contains Galaxies and stars, they move away with increasing speed. The scientists believe they can use several methods to measure the removal rate of Galaxies.
The astronomers have images of the Universe when it was 380,000 years old, and it is considered as a "baby" because the Universe is now 13.8 billion years old. The Big Bang lasted for a few moments, but it made space much larger by accepting quantum differences and increasing them in the process. These differences grew and widened, because in certain areas with increased density they had more gravity.
Over time, the differences became so significant that they were able to capture themselves on a conditional map of the Universe. The first periods of the existence of the Universe were marked by the difference in density, pressure, temperature. It influenced the development of alternative cosmologies and various ideas that suggested the existence of another Big Bang, it could form the Ekpyrotic Universe.
Translated from Greek, ekpyrotic means fire, and in ancient philosophy it means the idea of a constantly repeating Universe. According to that philosophy, an outer space is constantly repeating itself, being in an explosion phase that slows down in a strange way, returning to previous readings of temperatures and pressures.
Then another round of changes takes place and the Universe again plunges into a phase close to the Big Bang. The scientists' assumptions are based on the fact that the Universe is still not infinite. And there are processes the science knows nothing, and therefore it cannot be sure, whether the Universe is eternal or an inevitable end awaits it soon.
