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 Accelerator Laboratory. At the same time he admits that 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 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 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 has written a book in which he talks about four fundamental mysteries that cosmologists are currently exploding. The two greatest are the mysteries of dark matter and dark energy. Hooper argues that our knowledge of these pair of phenomena equals knowledge that people had on the air from 1850 onwards.

“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 it could help solve one of the other mysteries of modern cosmology – The ever-accelerating expansion of the universe. Physicists have found that the universe’s expansion has accelerated over the past 7 billion years. Behind this lies a hitherto unknown force, and it is believed that that force may be dark energy.

Scientists can’t find answers right now, but they seem to be hiding in the moment that happened immediately after the Big Bang. At this point, fundamental interactions that have shaped the universe as we know it today can take place. However, it all happened in a very small fraction of a second, Hooper says. These are such small numbers they are hard to imagine.

Yet these are crucial moments that can teach us about the space around us. Hooper also claims the Big Bang it didn’t have to be one. He imagines that just when our universe came into being, another big bang could have led to the creation of another universe. These universes would be in one huge space and would be separated by an impenetrable boundary.
