(ORDO NEWS) — The researchers said that time has a definite beginning. At the same time, it is not known whether it will have an end, because everything depends solely on the nature of dark energy. Most people are convinced that time can move exclusively forward, but physicists have a slightly different opinion on this matter.
It is worth noting that many laws of physics will still apply, even if time starts to go back. This is reported by Focus.
For a long time, experts were convinced that the universe was infinite and static. Studies have shown that it is expanding rather quickly. This suggests that it arose from a compressed state or as a result of the Big Bang. Accordingly, time actually has a beginning.
In absolutely all directions, the Universe will look almost the same, which indicates the existence of cosmic time. In order to be able to measure it, you will need to first measure a special microwave background. Due to this, specialists were able to determine the approximate age of the Universe, which reaches almost 13, 799 billion years.
The process of entropy that occurs in nature will help explain why time only moves forward. Its essence lies in the fact that over time, everything will become less orderly. As the development of the universe proceeds, the total entropy begins to increase.
