Stephen Hawking was right? Evidence of the existence of a previous universe

New data indicate that cosmologist Stephen Hawking’s ideas about the origin of the universe may have turned out to be a reality.

Recently, scientists have found something that may indicate signs of long-dead black holes. This alludes to the extinct Universe. Modern scientific concepts of space are based on the idea that the Universe came from one event - the Big Bang. But what came before this remains the greatest enigma with serious consequences.

We know that space is expanding. Scientists see galaxies moving outwards. But how far does it spread and how will it end? Will the universe just turn into emptiness? Or will it reach a certain turning point where space will begin to shrink? The late Stephen Hawking had a certain idea. Now, astronomers could, perhaps, prove that his views were correct.

Space inflation

The leading theory of the birth of space faces a problem: the evidence does not support it. It is based on the idea that one quantum speck of infinite gravity and density, like the singularity in the core of a black hole, suddenly awoke. Then it exploded and began to swell into the infant Universe in a split second.

It seems to be appropriate, as it is considered a convenient solution for many astronomical events. But such an event should have left visible signs. The way the universe woke up can show where it came from. There should be regular and predictable gravitational waves pulsating in space. But we did not fix them. Then the question of entropy arises (the tendency of things to behave erratically over time). Why did the universe not become a bubbling cauldron of disorganized subatomic particles scattered in a uniform layer? How do subatomic particles bind to atoms, molecules, gas, dust, and stars? Physics reports that for this the early Universe must have a lower entropy than it does now. But how?

Black holes remain the center of cosmic admiration. Whatever their role, they play the most important role in the universal destiny

Cyclic Cosmology

Black holes are so large and infinitely bizarre that their tracks can survive even the end of the Universe. At least, representatives of Oxford University, Warsaw University and New York Maritime College say so. Of course, such an extraordinary idea needs strong cosmological arguments.

Hawking's theory is the idea of ​​a conformal cyclic cosmology, where it says that our Universe was not the first and ... not the last! That is, in the world there is no end and beginning, and the Big Bangs continue to occur. This event is followed by the creation of space known to us. Gradually everything cools down, galaxies fly apart, stars die, the Universe becomes empty and only black holes survive.

But, if the universe continues, and black holes absorb everything, then in the end we should have only black holes. Hawking believed that black holes actually eject mass and energy, releasing gravitons and photons. This is called Hawking radiation. What remains? Nothing! In this time interval, massless gravitons and photons do not possess time and space. And it all starts again.

The search for shapes and patterns among cosmic clouds is as dangerous as looking at earthly clouds. This was reported by Stephen Hawking, when he noticed his own initials, printed against the background of cosmic radiation

Take a look at the sky

The main clue left over from the quantum soup that formed the first moments of our Universe is the radiation from the Big Bang (relic radiation). It still retains the templates printed at the very beginning, which is capable of including the influence of previous times - the Universe before ours. Bright traces can be obtained by Hawking concentrated radiation from the last dying black holes, which are called Hawking Points.

Now researchers believe they have found several such events. Relic radiation was mapped, but everything looks too erratic. The study resembles a search for figures in the clouds. It's about the point that Hawking jokingly called his own initials. Scientists have begun to create a model of the universe, which would reveal a larger model within itself.

Our relic radiation images are weak, but a third of the night sky remains relatively clear. The researchers figured out what they could find with Hawking Points and tried to compare them with the information we know. The data were then compared with 8,000 different simulated universes. Thus, we managed to find 20 “bright” spots. But these are not the ancient black holes themselves. Think of them as matching the notion that Hawking's huge clouds of radiation from dying black holes were transferred from one Universe to another.

Researchers believe black circular spots are Hawking Points (ghosts of black holes from the previous Universe)

New Horizon

Obvious bubbles against the background of relic radiation seem attractive, but there is no exact certainty of their nature. Some physicists believe that researchers have not sufficiently eliminated the prospect of random scattering. Others believe that if cyclic cosmology turned out to be true, then tens of thousands of Hawking Points should appear in the sky. And such flashes could indicate various events, such as a collision with a parallel universe.

There is one more inexplicable moment in the logic of the theory: how can a cold and empty universe suddenly burst into a new and high-energy one? But the authors of the study continue to study the issue, convinced that they are right. They even believe that the next Universe in general will resemble ours.
