Explanation:
According to the Big Bang theory , the universe was shrunk about 13.4 billion years ago (13.8 Billion year ago) . [1] Due to an explosion in it, every single particle was spread in it, which resulted in the creation of the universe. This expansion continues even today, due to which the universe is still spreading today. [2] This explosion emitted excessive energy . This energy was so high that the effect of the universe continues to spread till date. All physical beliefs are defined by a single phenomenon called the Big Bang Theory. The current beliefs of time, space had come into existence after a mere 1.83 second interval of the explosion of this great blast called Mahavistop . Laws of physicsStarted being implemented. In 1.34th second, the universe had spread 10 30 times and had become a hot substance of quarks , leptons and photons . At 1.4 seconds, quarks started forming protons and neutrons together and the universe had cooled down a bit. The existence of hydrogen , helium, etc. began to form and other physical elements began to form.
Answer:
The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now—and it is still stretching!
