What is the Big Bang Theory? | #aumsum

Many of us wonder how everything, that is humans, trees, planets, stars, galaxies, and even space and time came into existence. How did our universe originate? Now, there are several theories, beliefs and myths about the beginning of our universe. However, the most widely accepted explanation is the big bang theory, which scientists use to describe the initial formation of our universe. It states that our universe began from a very hot and compressed point, which is also known as a singularity. Based on estimations, it is said that approximately 13.7 or 13.8 billion years ago, the singularity violently exploded. This explosion is called the big bang. Scientists claim that from this explosion or big bang, space, time, energy, matter and then, stars, galaxies, humans, etc., came into existence. Now, you must be wondering, what happened before the big bang at singularity? It is said that at singularity, laws of physics and time did not exist. If time did not exist, then there is no reference point to determine what happened before the big bang. Also, don't forget to subscribe to our YouTube channel.
