This theory joins many of the theories put forward by scientists to solve the mystery of the origin of the universe. However, it is unlikely that we will be able to pinpoint what really happened billions of years ago.

What does the theory say?

According to the standard cosmological picture, the early universe is a very exotic place. The most important event in our space, Inflation is the extremely rapid expansion of the universe shortly after the Big Bang. When the inflation ceased, the exotic quantum fields that caused the event disintegrated into the stream of particles and radiation that still exists today. When our universe was less than 20 minutes old, these particles started coming together to form the first protons and neutrons – this is called Big Bang nucleosynthesis. It is considered a pillar of modern cosmology because the calculations underlying it accurately predict the amount of hydrogen and helium in space.

However, despite the success of the modern picture of the early universe, many mysteries remain. Example, Science still doesn’t really understand dark matter, the mysterious and invisible form of matter that makes up most of the cosmos’s mass.. The conventional view is that whatever process creates the particles and radiation, it also creates dark matter. And after that, dark matter was around, ignoring everything else.

But a group of researchers suggested an unexpected new idea. They argue that the Big Bang’s era of inflation and nucleosynthesis was more than one.

• Dark matter can evolve in an entirely separate orbit.
• In this scenario, when inflation ended, it filled the universe with particles and radiation, but not dark matter.
• Instead, some quantum field is left that has not disappeared.
• As the universe expanded and cooled, this additional quantum field eventually transformed, causing the formation of dark matter.
• The advantage of this approach is that it separates the evolution of dark matter from ordinary matter.

It also offers opportunities to explore a wide variety of theoretical models of dark matter because now that it has its own evolutionary path, it’s easier to follow the calculations to see how they might relate to observations. For example, the authors of the article were able to identify: If the so-called Dark Big Bang did occur, it must have happened when our universe was less than a month old..

Calculations also showed that the Dark Big Bang released a unique signature of the powerful gravitational waves that persist in the modern universe. Existing information, such as pulsar synchronization sequences, can detect these gravitational waves, if any.
