The universe may collapse, creating a new Big Bang

Many scholars argue that the universe we are seeing is just one of many different universes with its own stages of development including expanding, narrowing and appearing the Big Bang.

Scientists Maha Salah, Fayçal Hammad, Mir Faizal and Ahmed Farag Ali describe the laws of physics and the state of the universe before it was formed in a report published on August 3 on Cornell University's online library. , America. They also created a space model before the Big Bang , according to the International Business Times.

The universe can be simulated by Einstein's general theory of relativity. This theory predicts that the expanding universe and galaxies are moving farther away from us. If we go against this expansion process over time, we will come to the time when the universe began, which is the Big Bang explosion 13.7 billion years ago.

But at the time of the Big Bang, the laws of general relativity seemed to be broken. They are not able to help us understand how the Big Bang exploded.

First, the team demonstrated Einstein's equations in general relativity like thermodynamic equations. They then sought to adjust these equations based on quantum effects.

Currently, we do not have the quantum theory of gravitational fields, but there are many ways to describe gravitational interactions according to the principles of quantum mechanics, or quantum gravity . All of these approaches seem to describe indirectly about the structure of air - time is broken at small length scales. So no no - time is below this scale. Many approaches indicate that there is a maximum energy in the universe, and cannot have energy beyond the maximum energy level.

"The geometry of space-time is limited by the minimum length and maximum energy level that helps us understand the quantum gravity effect of the universe. At that time, we can study the universe first. when the Big Bang happened, " Mir Faizal, co-author of the article, said.

The research team used two input assumptions to describe thermodynamic factors in the equations of general relativity including: no - broken time at minimum length. Any object in the air - this time cannot have energy beyond a certain maximum energy level. The results show that the universe is cyclical, going through 4 separate stages.

"The equations reveal that the expansion of the universe will pause and then enter the contraction phase. The Big Bang explosion is not the beginning of the universe, it is just a transition. There is one Faizal explained, before the Big Bang, the current period and the other two periods .

Researchers face major challenges in model testing."I think it's difficult to calculate when the universe collapsed. What we can predict is that it will collapse , " Faizal said.
