I am a bit confused about big bang. Is the big bang referred to as the expansion of universe from singularity or not. Sorry if i have posted it in wrong section
That, sir, is an excellent question.Nstraw said:So if i am correct than the main question arises why universe was in the hot and dense state in the first place right?
Nstraw said:So are there any theories yet which suggest why
The Big Bang Singularity is a theoretical moment in the history of the universe, often referred to as the "beginning" of the universe. It is the point at which all matter and energy in the universe was compressed into an infinitely small and dense singularity.
The exact cause of the Big Bang Singularity is still unknown, but it is believed to have originated from a rapid expansion of space and time, known as inflation. This expansion caused the singularity to cool and expand, leading to the formation of the universe.
The main evidence for the Big Bang Singularity comes from observations of the cosmic microwave background radiation, which is believed to be leftover radiation from the initial explosion. Additionally, the expansion of the universe and the abundance of light elements also support the theory of the Big Bang Singularity.
No, there are other theories such as the Steady State theory and the Oscillating Universe theory. However, the Big Bang Singularity is the most widely accepted and supported theory among scientists.
After the initial explosion, the universe continued to expand and cool, allowing matter and energy to form into galaxies, stars, and planets. The expansion of the universe is still ongoing and is currently believed to be accelerating.
