Big Bang Cosmology is supported by all available evidence, and has been repeatedly tested and shown to conform to observations. All other possibilities have been shown to be counter to evidence, except perhaps the idea that someone is magically manipulating our observations so that they LOOK like a Big Bang.
The question is akin to asking, "Is a helio-centric system real or faked?"
no the no. of stars in the milky way is not the evidence in support of the big bang cosmology.
Scientists who study Big Bang Cosmology are (generally) referred to as cosmologists.
The big bang theory is a model of cosmology it does not have any relation with earth's creation .
Big Bang Cosmology deals with the start (not necessary a creation) of our Universe as a whole, not with our Earth.
About 378,000 years after the Big Bang. For more details, check the Wikipedia article on "Recombination (cosmology)".
The history of the Big Bang theory began with the Big Bang's development from observations and theoretical considerations. Much of the theoretical work in cosmology now involves extensions and refinements to the basic Big Bang model.
Yes
All people who believe in the value of observational evidence accept Big Bang Cosmology, just like they accept a heliocentric solar system. In both cases, no other proposal matches what we see, and every significant alternative has been falsified. There are some people who oppose Big Bang Cosmology based solely on their initial presumption of reality: that our entire Universe is significantly younger than 100,000 years. If you START with that presumption, Big Bang Cosmology is, of course, false. The problem is that no observational evidence whatsoever supports that presumption.
He didn't. Although Hawking has done an immense amount of theoretical work on black holes, as well as the topology of our Universe, he has always taken Big Bang Cosmology as his starting point. That's because, by the time he got his PhD in 1966, observational evidence had pretty much ruled out any cosmology but Big Bang. Hawking has simply improved our mathematical understanding of BBC.
It accounts for the beginnings of both space and time in the universe.
Key figures associated with the cosmology of the Big Bang theory include George Lemaitre, a Belgian physicist and Catholic priest who first proposed the theory, and Edwin Hubble, an American astronomer whose observations supported the expanding universe predicted by the Big Bang. Other notable contributors include Alan Guth, Andrei Linde, and Stephen Hawking.
The theory that suggests for every big bang there is a crunch is known as the "Big Crunch" theory. It proposes that the expansion of the universe will eventually stop and reverse, leading to a contraction of the universe back to a singular point, followed by another big bang.
