Question

What is proposed as evidence that supports the Big Bang Theory?

Answer 1

Evidence that shows that the observed universe is expanding

The red move saw known to man was one of the primary types of proof for the Enormous detonation. The red move or doppler impact gives proof that the watched items known to mankind are moving far from one another. On the off chance that the items known to man are moving far from one another, the universe is extending.

The rationale is if the universe is growing now it probably been littler at one time. Extrapolating in reverse the universe is proposed to have been at one time a superdense wad of issue.

Such a superdense wad of issue would have been shaky. The Huge explosion recommends that this superdense ball detonated.

The possibility of the universe starting with a touchy extension predicts that there ought to be foundation radiation. This anticipated foundation radiation was found giving additional proof to the Theory of how things came to be.

The Theory of how things came to be was opposed in light of the fact that researchers used to trust that the universe was everlasting and existed in a relentless state. The predominant logical rationality of material authenticity ordered that issue and vitality are on the whole that there is and in this manner must be everlasting. Proof that the development of the universe is expanding in rate demonstrates that the present universe had a start as well as have a consummation.

Answer 2

That's not the way it works.

Real scientists don't gather evidence to support a theory that they made up.

Real scientists build a theory to explain the evidence that they observed.

The so-called "Big Bang" theory is the best explanation ... so far ... of:

-- the observed Cosmic Background radiation,

-- the observed probable expansion of the universe (not "proved"),

-- the observed probable existence of "dark matter" (not "proved"),

-- the observed success of predictions that come from standard theories of fundamental particles, and

-- the observed success of predictions (like GPS) that come from Einstein's general theory of relativity.  

BUT ! If you come up with a better explanation tomorrow ... one that explains the observed evidence more accurately, and makes more accurate predictions of things that we can observe or test ... then the "Big Bang" theory will go out the window, and the scientific world will adopt the "Sid4067" theory for the same evidence that we already have.
