There is probably another universe beyond our universe.
While many of us can’t even imagine what the universe is like in its infinity, scientists think they already know what happened before. They allegedly found the answer to the question of what it was like before the big bang. And their findings are clearer than one might think: the unscientific versions of the answer to this question have essentially been the basis of all religions and most philosophies. What do we mean?
“The last star will slowly cool down and die. With its disappearance, the universe will once again become a void, devoid of light, life and meaning.” So the physicist warned Brian Cox in the BBC Space series.
Have you ever wondered what existed before the universe began? And do we really know where we are in the universe? It is impossible to know what existed before the creation of the universe. At least many physicists consider this question meaningless and argue that the big bang that created the universe was actually the beginning of time.
The universe may be finite, but even if it were, it is currently impossible to observe what lies beyond it, or to place it in a larger system. However, a new theory points the way.
The cyclic universe is the answer
Until now, we thought the universe started with a big bang. But a team of mathematicians from Canada and Egypt refutes this hypothesis in a new study that uses cutting-edge scientific theories and a huge set of equations to prove that the universe didn’t start with a big bang. To defend their opinion, scientists used theories from the world of quantum mechanics.

The phases of space as states of water
The universe basically goes through four different stages, according to a new study. And what we imagine under the word universe is just another “cosmological phase” of ourselves, that is, the universe. Precisely because the universe is infinitely large, it is cyclical and has always existed in one of the four phases.
So even as the universe is expanding, some changes caused by quantum mechanics will eventually stop the expansion. Everything will return to a point near infinity and then the universe will begin to expand again. Doesn’t that make you wise?
“In our cosmological model, the universe didn’t start with a big bang, but there was a phase transition from one phase of the universe to another.” explains the professor Mr. Faisalwhich compares the four different phases of the universe with the three different phases, or better states, of water. “Just as we can learn about the properties of ice by studying the water that formed from it, we can learn about pre-big bang cosmology by studying the physics of this universe.”
Does the universe have borders?
Cosmological model
The expansion of the universe stops at some point and is immediately followed by a phase of contraction. “The new cosmological model eliminates the places where the laws of physics are violated. Therefore, even the singularity of the big bang can be avoided”, Faisal says.
In the cosmological model of scientists, the cyclic nature of the universe arises as a result of adding quantum effects to the cosmological model of the universe. Although there are many different approaches to quantum gravity, what most of these different approaches have in common is that there is a minimum length below which space does not exist. Likewise, there is also a maximum energy and no object in the universe can have an energy greater than this maximum energy.
The research team incorporated the effect of minimum length and maximum energy into a cosmological model and created a cyclic universe.
What’s beyond the limit of the visible universe? Maybe something completely different from what we know

To say that the universe was invented or created is to make a hypothesis that few physicists make. On the question of what existed before the creation of the universe, those who address the question are divided not into alternative explanations, but between those who say that the question means something and those who consider it completely meaningless.
Before the universe, there was only the universe again, just in a different phase. This is the ultimate knowledge.
