According to a new research study, there may have been two Big Bangs that created the universe billions of years ago.
According to a group of scientists, after the first Big Bang, another transformative event occurred that flooded the universe with mysterious dark matter. It’s been dubbed the “Dark Big Bang” by astronomers.
Dark matter is a hypothetical component of the universe whose existence is determined by gravitational attraction rather than luminosity.
It has no interaction with light or electromagnetic fields and accounts for 30.1 percent of the known universe. The reset is made up of dark energy (69.4%) and “ordinary” visible matter (0.5%).
The scientists propose that a “Dark Big Bang” may have “occurred when the universe was less than one month old
Since Swiss-American astronomer Fritz Zwicky proposed the theory in 1933, astronomers have been unable to explain why clusters of galaxies move in ways that our current standard model of physics cannot account for.
The scientists propose that a “Dark Big Bang” may have “occurred when the universe was less than one month old” in a yet-to-be-peer-reviewed paper on the preprint database arXiv.
“People always assume everything is created at the same time in a single big bang, but who really knows?” Katherine Freese, a physics professor at the University of Texas at Austin who co-authored the paper, told New Scientist.
According to the team, the event could have triggered several types of dark matter, including “darkzillas” (a reference to “Godzilla”), which are monstrously sized particles 10 trillion times the mass of a single proton.
The scientists claim that current gravitational wave experiments are incapable of detecting signatures of the Dark Big Bang, but they are hopeful that another gravitational wave probe using distances to distant pulsars, known as Pulsar Timing Arrays, such as the NANOGrav experiment, may be able to do so.
