Daily asking questions about astronomy and cosmology
How much big bang theory is correct?
General thoughs...
How did the universe begin, if you talk to any person about this, then it is obvious that a few questions will arise in his mind...
Were you there when the universe was being created?
So our answer will be no, i was not there! ... then he will ask how do you know how this universe began?
But for those who know, believe and understand science,on the basis of some evidence some theories have been presented by scientists and these theories were presented at different times under different evidence. One of the most popular theory is Big bang.
Introduction of Big bang!
Big bang theory is related to the beginning of the universe, purposed by Georges Lemaître
The Big Bang Theory is a widely accepted scientific explanation for the origin and evolution of the universe. It is supported by a large body of evidence from various fields of science such as astronomy, physics and chemistry. Like all scientific theories, it is subject to further testing and refinement as new evidence emerges over time.
Evidence for the correction of Big bang:
There is significant evidence that the universe began with one such event, the "Big Bang". Three main pieces of observational evidence support the Big Bang theory:
Measured abundance of elements,
The observed expansion of space,
the discovery of the Cosmic Microwave (CMB).
A wide range of experimental evidence strongly supports the Big Bang event. , which is now basically universally accepted
. Detailed measurements of the universe's expansion rate place the Big Bang singularity at an estimated 13.78 billion years ago, which is considered the age of the universe.
