Ever since the Big Bang of about 13.7 billion years ago, all matter has been moving apart from each other. Fortunately, this tendency for matter to fly apart is more than counter-acted by the force of gravity -- at least over "short" distances (like the size of a galaxy).
Why our Universe is composed almost entirely of matter, with almost no anti-matter in it.
All matter. All the matter that exists emerged from the primordial cosmological state that we call the 'Big Bang'.
According to the big bang theory the universe began about?
creation of the universe and all matter
There are various scientific theories about the origins of matter, but the Big Bang theory is the most widely accepted explanation for the early moments of the universe. If the Big Bang theory were to be proven false, it would require a new, evidence-based theory to explain the creation of matter. However, as of now, the Big Bang theory remains the prevailing scientific understanding of the universe's origins.
the big bang theory
the "big bang" theory, is a theory as to how the universe was created from the explosion of a single, very large, very dense, body of matter. so in "theory" the people or earth only exist because of the big bang
Hello i am minakshi answer is that the big bang theory is an example of old scientific theory as big bang theory explains that there was an explosion but the isotropy and the homogenity of the universe is not explained by big bang theory to explain his we connect inflatation theory with big bang theory to explain it so the big bang theory is also an example of old scientific theory.
The big bang happened something like 14 billion years ago. As an instant in time that is true, as a process it is still happening at every point in space as that point expands into a finite volume and drags matter and energy with it.
The best theory is that all matter was created at the Big Bang
There are two questions commonly asked:1. Is it real, or did God create the universe ex nihilo?2. Did the Big Bang create more than one universe?3. How can the big bang account for dark matter and dark energy?
You are giving the definition for the Big Bang Theory.
