What if The Universe Started With a Dark Big Bang?

There might have been more than one Great Bang. Another Big Bang that filled our universe with dark matter particles may have occurred at the same time as the emergence of all the particles and radiation in the cosmos. And perhaps we can find it.

According to the conventional cosmological theory, the early cosmos was a very strange world. The event of inflation, which occurred very soon after the Big Bang and caused our universe to experience an era of highly rapid growth, was perhaps the most significant thing to occur in our universe.

When inflation came to an end, the exotic quantum fields that were responsible for it decayed, changing into the current deluge of particles and radiation.

These electrons started to put themselves together into the first protons and neutrons less than 20 minutes after the Big Bang, a process known as Big Bang Nucleosynthesis.

Large Explosion The equations underlying nuclear synthesis are a cornerstone of contemporary cosmology because they reliably forecast the quantity of hydrogen and helium in the universe.

We still don't comprehend dark matter, the enigmatic and invisible form of matter that makes up the overwhelming bulk of the universe's mass, despite the success of our model of the early universe.

In Big Bang theories, it is generally accepted that the same process that produced electrons and radiation also produced dark matter. The dark matter then continued to linger, oblivious to everyone else.

However, a group of experts have put forth a novel concept. They contend that the Great Bang and inflationary periods weren't unique.

It's possible that the evolution of dark matter took a totally different path. In this situation, even after inflation stopped, the cosmos was still flooded with radiation and particles. Dark matter, however, not. Instead, a portion of the quantum field persisted and did not vanish.

That additional quantum field ultimately underwent a transformation that led to the creation of dark matter as the universe cooled and expanded.

This method has the benefit of separating the development of dark matter from that of ordinary matter, allowing us to continue understanding the Big Bang Nucleosynthesis while dark matter develops on a different path.

This method also makes it possible to investigate a wide range of theoretical models of dark matter because it is now simpler to keep track of in computations to see how it might relate to data because it has a distinct evolving trajectory.

For instance, the authors of the article were able to conclude that the so-called Dark Big Bang, if it occurred, must have occurred when our universe was only a few days old.

The study also discovered that the emergence of a "Dark Big Bang" produced a very distinctive trace of powerful gravity waves that would last into the universe as it exists today. If these gravity waves exist, they should be able to be found by current studies like pulsar timing arrays.

Although the existence of a Black Big Bang is still unknown, this study provides a direct route for investigating the theory.
