Question

what is the big ban theorey

Answer 1

$\huge\red{Answer\: is}$

The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today.The Big Bang is the singular cataclysmic event that started it all: the instant 13.8 billion years ago that marked the fiery birth of the universe.

The Big Bang Theory is an American television sitcom created by Chuck Lorre and Bill Prady, both of whom serve as executive producerson the series, along with Steven Molaro. All three also serve as head writers.

When the size of the universe at Big Bang is described, it refers to the size of the observable universe, and not the entire universe. Hubble's law violates the special theory of relativity: Hubble's law predicts that galaxies that are beyond Hubble Distance recede faster than the speed of light.

Answer 2

Explanation:

The Big Bang theory is a cosmological model of the observable universe from the earliest known periods through its subsequent large-scale evolution.[1][2][3] The model describes how the universe expanded from an initial state of extremely high density and high temperature,[4] and offers a comprehensive explanation for a broad range of observed phenomena, including the abundance of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure.
