What Caused The Big Bang?

Did you know anything about the Big Bang theory? Wondering what it is? It’s actually the scientific explanation of our Universe’s history. By hearing the name, you might be wondering that it begins with the explosion but that’s not true instead it starts with the expansion. 

As per the theory of the Big Bang, the universe was smaller than the atom once. All the matter in a universe was concentrated within a small point with a massive mass and this point was known as singularity. Approximately 13.8 billion years ago, that minute point started to expand quickly. It kept on growing and growing. After the Big Bang, light was not possible since the universe was extremely hot. Can you believe that? No light was there at any point. As matter began to cool slowly, stars formed and began emitting light. Also, other matters formed into the planets, asteroids, comets etc. in our universe. 

The Big Bang cause; which marked the universe’s beginning remains an unanswered interrogation in cosmology. The theory of the Big Bang describes the expansion as well as the Universe’s evolution from a hot and solid-state about 13.8 billion years ago. But it doesn’t give the explanation for the cause of the initial singularity; the minute our universe began. 

Numerous theoretical concepts have been planned for exploring the Big Bang cause however these are hypothetical and also have not been conclusively proven. Below given are a few key concepts:

• Quantum Fluctuations: Few theories suggest that quantum fluctuations may have triggered the Big Bang in the pre-existing space. These fluctuations might result in the expansion of the universe from an extremely small and hot state. 
• Multiverse Hypothesis: Few cosmological theories suggest the presence of the multiverse; where the universe is merely one of the numerous universes with distinct physical properties. Within this framework, the Big Bang cause in our universe might be connected to processes within an extensive multiverse context. 
• Quantum Cosmology: Quantum cosmology endeavors to apply the quantum mechanics principles to the complete universe including its inception. Few models of quantum cosmology suggested that the universe came into existence through a process similar to tunneling from the quantum state. 

It’s vital to emphasize that all these concepts are deeply theoretical as well as depend on intricate mathematical as well as physical concepts. Also, they are the subject of endless research and discussion in the scientific community. 

We lack conclusive observations that enable us to identify the exact Big Bang cause. The conditions at or simply before the Big Bang moment are pretty challenging because our present physical theories including general relativity as well as quantum mechanics become scarce under such thrilling and extreme conditions.
