What different forms of evidence support the Big Bang Theory?

Answer 1

Bones gives you the best answer. The hot big bang would create hydrogen, helium, lithium, and trace amounts of beryllium. These are the first four elements of the periodic table.

Bones is correct: Spectroscopic analysis of the light from the most distant galaxies (ten billion light years from us) reveal ratios of these elements in close agreement with the values predicted by the big bang. Stellar nucleosynthesis--the forging of heavier elements in the hearts of stars--accounts for the difference, as does production of elements heavier than iron in supernova.

Another fact: The natural abundances of elements parallels their expected stellar nucleosynthesis and supernova production values. Coincidence? Of course, this in itself is not necessarily evidence for the big bang.

The expansion of the universe (galactic redshift) indicates either the big bang or steady state models. However, the steady state has difficulty accounting for the cosmic background radiation--the "echo" of the big bang. This is probably the strongest piece of evidence in favor of the big bang model.

The distribution and evolution of the galaxies also fits very well the inflationary hot big bang model.

One piece of evidence that argues against the inflationary hot big bang model is baryon assymetry. Baryons are particles comprised of three quarks, such as the proton. The assymetry lies in the fact all the protons we see are positive. The big bang model predicts there should have been a much more equal production of matter and antimatter. Somehow there came to be a big imbalance.

No competing cosmology addresses this imbalance any better than does the inflationary hot big bang model.

Answer 2

the most convincing evidence comes from the cosmic microwave background, also the fact that the universe is expanding, another good argument for the big bang is that the theory predicts what types of element should be found in space and how much of those elements are present. the cool thing is, is that this is exactly what scientists have found.

Answer 3

a million. distant galaxies teach a pink shift of their spectrum. the quantity of shift is larger for more advantageous distant galaxies. 2. The abundance of sunshine factors (hydrogen, helium, lithium) tournament those envisioned from modeling the nice and cozy enormous Bang. 3. The cosmic historic past radiation suits that of a black body to an quite extreme precision. No concept with no warm enormous Bang provides this. 4. The fluctuations in the historic past radiation tournament those envisioned from inflationary fashions. 5. Galaxies that are more advantageous distant have different characteristics than those interior sight: the farther ones emitted their life in the route of the tremendous Bang and teach how galaxies change via the years.

Answer 4

Well we do know the universe is expanding outward so its elementary to deduct that the matter now expanding was once at one central point.

Galaxies are all flowing outward from one central point. The distance between them is getting larger.

When the universe was young there were Super Suns. Those were the biggest stars. They were the first. They burned up fast and exploded and formed smaller suns. And then smaller suns.

Look up super suns. In fact I think I will too. It sounds really interesting. I read about them is Carl Sagan's book.

Answer 5

Both the fact that everything seems to be moving away from everything else and the 'background radiation' that fills the Universe which is the faint 'echo' of the Big Bang.

Answer 6

Welcome to whats gonna happen again.. soon..BOOM Krakatoa..wow man yellowstone.just think it could go boom just like krakatoa did,farout manGod is lettin use know he is on the way,
this old world has had enough man.
Mankind has killded her,poisons, gases, smoke from factruies,All good things must come to a end..same as the wildwood weed.

Answer 7

its mostly astronomical evidence that we have using space telescopes, and the inferences made on the current theories that we have.

Answer 8

the expanding universe all from a nucleus
