Is the big bang something unique, or could it have happened more than once?


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

The Big Bang theory is a widely accepted theory from the origins 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 different elements, it all fits. All data suggest that the universe came into existence just as this theory predicted. From this perspective, understanding the origins of the universe may seem less complicated.

Hooper has written a book in which he talks about four fundamental mysteries that are currently exploding cosmologists. The two biggest are the mysteries of dark matter and dark energy. Hooper argues that our knowledge of this pair of phenomena is equal to that of knowledge which people had in the air from 1850.

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

The greatest mysteries of the universe

According to him, dark energy is more interesting than dark matter. He claims he could help solve another of the mysteries of modern cosmology – Faster expansion of the universe. Physicists have discovered that the expansion of the universe has been accelerating over the last 7 billion years. Behind this is an unknown force as yet and it is assumed that that force may be dark energy.

Scientists are currently unable to find answers, but appear to be hiding in the moment that happened immediately after the big bang. At the moment, there could be a fundamental interaction that shaped the universe as we know it today. However, it all happened in a very small fraction of a second, Hooper said. These are such small numbers they are hard to imagine.

Nevertheless, these are crucial moments that could 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 led to the creation of another universe. These worlds would be located in one vast space and would be separated by an impermeable border.
