Is the Big Bang something special, or has it happened more than once?



In recent years, scientists have made significant strides in understanding our universe and its origins, says Dan Hooper, a scientist at the Fermi National Accelerator Laboratory. At the same time, however, he admits it we have no idea what happened right after the big bang, writes the DailyGalaxy portal.

The Big Bang theory is a widely accepted theory of the origin of everything we know. If we consider the expansion of the universe, the temperature of the cosmic microwave background, or the presence of various elements, everything fits. All data suggest that the universe arose exactly as this theory predicted. From this point of view, it may seem that understanding the origin of the universe is not such a complicated process.

Hooper wrote a book in which he tells about the four basic mysteries that cosmologists are currently exploding. The two biggest are the secrets of dark matter and dark energy. Hooper argues that our knowledge of this pair of phenomena is equal to our knowledge which people have been floating in the air since 1850.

“We knew it existed, but we had no idea what it was made of,” writes Hooper.

The greatest secrets of the universe

According to him, dark energy is more interesting than dark matter. He claims that it can help solve another of the mysteries of modern cosmology – The ever-accelerating expansion of the universe. Physicists have found that the expansion of the universe has accelerated over the past 7 billion years. Behind this is a hitherto unknown force and it is assumed that it may be dark energy.

Scientists are currently unable to find the answer, but seem to be hiding in a moment that immediately followed the Big Bang. At this point, the fundamental interactions that have shaped the universe as we know it today may be taking place. However, it all happened in a very short split second, says Hooper. These are such small numbers it’s hard to imagine them.

Nevertheless, these are key moments that can teach us about the space around us. Hooper also claims the big bang it didn’t have to be just one. He imagines that just as our universe came into being, another big bang could have created another universe. These universes would be contained within one immense space and would be separated by an impenetrable boundary.
