Do you know what was the universe called before the big bang happened? Probably not. Because scientists have no proper evidence of existence before the big bang. Read More: 7 Facts You Should Know About the Universe

However, current scientific understanding tells us that the Big Bang was the origin of the universe. It means, before the big bang, there was no such universe that we can know with our senses.

Theories of physics such as cosmic inflation and the multiverse propose that our observable universe was preceded by other universes or eras, but it’s still a matter of ongoing research and debate.

It’s worth noting that pre-big bang theories or models are also a current topic of research in physics and cosmology, but it’s currently a subject of ongoing research and debate.

How big bang happened?

The Big Bang theory is the current leading explanation for the origin of the universe. According to this theory, the universe began as an incredibly hot and dense state, and has been expanding and cooling over time.

The idea of the Big Bang was first proposed by Belgian priest and scientist Georges Lemaître in 1927, but it was later developed and refined by other scientists such as Edwin Hubble and George Gamow. 

The observational evidence supporting the Big Bang includes the cosmic microwave background radiation (the afterglow of the Big Bang), the large-scale structure of the universe, and the abundance of light elements such as hydrogen and helium.

As per current understanding, the Big Bang Theory describes the universe began as a singularity, a point of infinite density and temperature, around 13.8 billion years ago. It then expanded and cooled, and the energy from this expansion caused matter and antimatter to form.

It is important to note that the Big Bang is still a topic of ongoing research and debate in the scientific community, and there are some aspects of the theory that are still not well understood.

For example, scientists are still unsure about the exact nature of the initial singularity, and about the physical processes that caused the universe to expand and cool.

Additionally, the big bang models have evolved through time, currently the most widely accepted model is known as the Lambda-CDM model (LCDM), this model describes the universe as spatially flat, homogeneous, isotropic and composed of various forms of matter, including dark matter and dark energy, this model have many observational evidence supporting it.
