What evidence in 1956 that supports the big bang theory?

Answer 1

1) The existence, isotropy, and spectrum of the Cosmic Microwave Background Radiation. It was predicted sixteeen years before it was detected, and has been found to be exactly as proponents of Big Bang Cosmology (BBC) say it should be. All other hypotheses are reduced to saying, "I know the CMBR is there, I just have no explanation for it."

2) The red-shift of all distant galaxies, with the size of the red shift being proportional to the galaxies' distance from us. All observations of this red shift support a Universe that was far denser about 13.7 billion years ago.

3) The ratio of hydrogen and helium in our Universe is exactly as predicted by BBC.

4) Quasars are distant from us (ie, far in our past), but none are close.

5) The ratio of isotopes with long half-lives to their decay products show none of the former existed prior to about 12 billion years ago.

6) No white dwarf stars -- which will remain stable for tens of trillions of years -- have been found older than about ten billion years.

The evidence for BBC is as strong as the evidence that our Earth goes around our Sun.

Answer 2

The Big Bang Theory perfectly predicts the Cosmic Background Radiation; no other hypothesis can even begin to do so.

Edwin Hubble, the man that invented the Hubble telescope, discovered evidence to support the big bang theory. In 1929, Edwin Hubble discovered that the distances to far away galaxies were generally proportional to their redshifts-an idea originally suggested by Lemaître in 1927. Hubble's observation was taken to indicate that all very distant galaxies and clusters have an apparent velocity directly away from our vantage point: the farther away, the higher the apparent velocity.

Answer 3

Mainly Red-shift and CMBR (Cosmic Microwave Background Radiation).

Red-shift supports the BBT alot because galaxies are move away from us at a single point. The further it moves away from us, the faster it moves so it will have a longer wave length, therefore the light is shifted at the red end of the spectrum. Also we believe that the reason why galaxies are moving away from us suggests that the universe is expanding caused by the explosion of the big bang.

For CMBR, scientists have detected low frequency electromagnetic radiation from all parts of the universe, mostly microwaves. When the universe expands and cools, the background radiation cools and drops in frequency.

Answer 4

The Cosmic Microwave Background, discovered (almost by accident) in 1964,

Answer 5

Cosmic Radio Background in the form of microwave.

Expanding Universe.

Answer 6

The redshift of distant galaxies and the cosmic microwave background are the two strongest pieces of evidence.

Answer 7

The most significant piece of evidence concerning the big bang is the remnants of cosmic background radiation left over from the big bang.

Answer 8

There is Red Shift, which indicates that all the galaxies are moving away from us and a fixed point in the universe, as our galaxy is.

Answer 9

The evidence in 1956 was the neutrinos discovery.

Answer 10

The expansion of the Universe, as can be seen by the redshift of distant galaxies; also, the cosmic background radiation. Read the Wikipedia article on "Big Bang" for more details.
