1.the observed wavelength of the
dark line from the distant galaxy
has increased
2.therefore the distant galaxy must
be moving away from the Earth
suggesting the Universe is
3.expanding outwards from a small
initial point
The big band theory
That would be the Big Bang theory.
What is known as the Big Bang Theory is the currently recognized model of how the universe began.
The Big Bang theory. The coining of this term is attributed to Fred Hoyle.
The CMBR did not reveal anything DIRECTLY about the age of our Universe. However, its spectrum and isotropy are almost perfectly as predicted by a Universe that began to expand about thirteen billion years ago -- a timeline given by the Hubble Constant. As such, it gives extremely strong support to that timeline.
'Singularity' ; a moment when energy exploded and matter was created.

The Big Bang.
That is, more or less, the description of the Big Bang.

The big band theory
The big band theory
The big bang theory which is a theory of cosmology holding that the expansion of the universe began with a gigantic explosion between 12 and 20 billion years ago
That would be the Big Bang theory.
The universe began approximately 13.7 billion years ago. The big bang theory describes how the universe was created, and began to expand rather rapidly.
The origin of the universe is just that - a theory. We can only speculate how universe began - based on the knowledge we have up to now. There may be other factors - that could change our perspective on how the universe began - yet to be discovered !
