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 Houer, a scientist at Fermi National Accelerator Laboratory. At the same time, however, he acknowledges this we have no idea what happened right after the big bang, writes the portal DailyGalaxy.

The big bang theory is a widely accepted theory about the origin of everything known. 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 show that the universe originated 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.

Houer has written a book in which he talks about the four main secrets that are currently exploding cosmologists. The two biggest are the secrets of dark matter and dark energy. Houer argues that our knowledge of this pair of phenomena is equal to our knowledge which people have been in the air since 1850.

“We knew it existed, but we had no idea what it consisted of,” Hoer writes.

The greatest secrets of the universe

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

Scientists are currently unable to find the answers, but they seem to be hiding at a time immediately after the big bang. At this point, a fundamental interaction could take place that formed the universe as we know it today. However, it all happened in a very small fraction of a second, says Houer. These are such small numbers that they are hard to imagine.

Nevertheless, these are crucial moments that could teach us about the space around us. Hoopers also claims a big bang it didn’t have to be just one. He imagines that as soon as our universe came into being, another great explosion could have led to the creation of another universe. These universes would be in one vast space and would be separated by an insurmountable boundary.
