Is the big bang something unique, or could it have 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 Launcher Laboratory. At the same time, however, he acknowledges that we have no idea what happened immediately after the big shock, writes the Daily Galaxy portal.

The Big Bang Theory is a widely accepted theory of the origin of everything we know. If we take into account 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 came into being exactly as predicted by this theory. From this point of view, understanding the origin of the universe may seem like a complicated process.

Hooper wrote a book about the four basic mysteries that cosmologists are currently exploding. The two greatest are the mysteries of dark matter and dark energy. Hooper argues that our knowledge of this pair of phenomena is equal to knowledge which humans have had in the air since 1850.

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

The greatest mysteries of the universe

According to him, dark energy is more interesting than dark matter. He argues that this could help solve another of the mysteries of modern cosmology – The ever-accelerating expansion of the universe. Physicists have discovered that the expansion of the universe is accelerating in the last 7 billion years. Behind this hides a hitherto unknown force and it is assumed that that force can only be dark energy.

Scientists can not find answers at the moment, but they seem to be hiding in the moment that happened immediately after the big shock. At this point, fundamental interactions could take shape that shaped the universe as we know it today. However, it all happened in a very small fraction of a second, says Hooper. These are such small numbers that it is difficult to imagine.

However, these are key moments that can teach us about the space around us. Hooper also claims a big bang did not have to be just one. He imagines that just as our universe came into being, another great blow could lead to the creation of another universe. These universes would be housed in a vast space and separated by an impenetrable boundary.
