One of the most important events that happened in the cosmos was that of inflation, that time after the Big Bang explosion sent the universe into a period of expansion.
By the time inflation ended, the quantum fields that drove this event weakened, transforming into millions of particles and radiation that remain to this day.
When the universe was less than 20 minutes old, those particles began to assemble into the first protons and neutrons during what is known as big bang nucleosynthesis .
These findings allow us to know a large part of the universe, but scientists have not yet been able to verify the origin of dark matter, which, according to the European Organization for Nuclear Research, occupies 27% of the cosmos.
Some models of the Big Bang suggest that any process that generated particles and radiation also created dark matter.
But University of Austin scientists Katherine Freese and Martin Wolfgang Winkler have published a new theory proposing a second explosion that created dark matter. It is the “Dark Big Bang”.
