There are more than just four observations that Big Bang Cosmology easily explains, but alternatives to BBC completely fail to do so.
1) Hubble Red Shift
2) The existence, isotropy, and spectrum of the Cosmic Microwave Background Radiation.
3) The ratio of hydrogen to helium in all parts of our Universe.
4) The ratio of long-lived isotopes to their decay products do not allow any of the former to have existed more than 10 billion years ago.
5) No white dwarf stars have been found older than 10 billion years.
6) Quasars are observed far from us, but none are close.
No
Scientists who study Big Bang Cosmology are (generally) referred to as cosmologists.
Scientists believe that several key pieces of evidence support the Big Bang theory, including the observed expansion of the universe, cosmic microwave background radiation, and the abundance of light elements like hydrogen and helium. The redshift of distant galaxies indicates that the universe is expanding, while the cosmic microwave background radiation is thought to be the afterglow of the initial explosion. Additionally, the proportions of light elements align with predictions made by Big Bang nucleosynthesis. Together, these observations provide strong support for the theory.
Real scientists do not "gather evidence in support of" any theory. The technical term for that kind of thing is "cherry-picking". Real scientists build a theory to explain the evidence that they have already gathered, and then test the theory to see whether it holds water. The easiest, fastest way to make sure that you are regarded as a wingnut by real scientists is to adopt or invent a theory, and then spend your time trying to prove it.
It depends, because some might say 'scientists'. But not all scientists believe in this theory. Also, there are those who believe in a similar idea to the Big Bang, but it is not refered to as 'The Big Band Theory.'
Discard it all.
The Doppler effect and background cosmic radiation are the big ones.
the big bang theory
Before the Big Bang theory, many scientists believed that the universe was static, or infinitely unchanging.
The Big Bang theory isn't a mystery: the scientists working on it know exactly what they mean by what they say.
Answer: Certainly not.
The Big Bang Theory
No
The Big Bang Theory
Scientists do not widely accept the steady state theory because it does not align with observed evidence such as the cosmic microwave background radiation and the Hubble expansion of the universe. These observations strongly support the Big Bang theory, which is the prevailing cosmological model.
It is a theory, therefore it was not discovered. It was thought up by scientists and philosophers.
Still now the most acceptable theory on the origin of universe has been the big bang theory. you can get more info on big bang theory from wikipedia.
