What if there was a second big bang? Here are the latest revolutionary theories

Cosmologists speculate that there may have been a second Big Bang that could explain the great abundance of dark matter in the universe

Astronomers have long tried to explain why galaxy clusters move in ways that our current standard model of physics cannot. To make matters worse, the most common explanation is that there is too much that we cannot see. Some researchers wonder whether the Second Big Bang brought so-called “dark matter” into existence shortly after ordinary matter. Which we are used to dealing with.

What is dark matter

The matter from which we are created, as well as the matter that makes up the stars, planets, and galaxies, all together, is nothing but 4.9% of the universe. However, about 26% of the universe is invisible matter, i.e. matter whose composition we do not know. The remaining 69% is dark energy, which we don’t know much about, but it exists. The fact that it is dark That doesn’t mean it’s not thereIt just means that it does not emit any type of electromagnetic radiation, neither within the visible light spectrum nor in X-rays. Although it is still a mystery, dark matter behaves exactly the same Like common materialRegarding its interaction with space-time. In practice, it dilutes when it can expand to a large size and exerts the same gravity as ordinary matter.

The “Big Dark Bang” as an explanation for dark matter

We are accustomed to believing that everything was created simultaneously in one big bang, but in reality we cannot confirm this yet. In this latest research, a team of scientists suggests that the “Big Dark Bang” may have occurred when the universe was less than a month old. It also suggests that the event may have created different types of dark matter, including so-called “darkzillas”, which are particles of enormous size. 10 trillion times the mass of a proton. These particles are not very different from those known as “weakly interacting massive particles” (WIMPs), which astronomers have hypothesized for decades to explain mysterious forces that lie outside the Standard Model of physics. Now, by analyzing gravitational waves emitted by pulsars, scientists hope to find traces of the “dark Big Bang” and better understand the first moments of the “life” of the universe. If this theory is confirmed, it will be a landmark breakthrough in understanding the universe as we know it.
