The Big Bang theory tells us how the Universe began and is evolving.

In essence, it is a theory that was created to explain two facts that we know about the Universe - it is gradually expanding and cooling. In the 1920s, Edwin Hubble found that galaxies far from our own Milky Way are moving away from us.

the Big Bang, known as the cosmic microwave background [or CMB for short], which revealed that the Universe was once a very hot, hostile place. Both these discoveries led astronomers to deduce that the Universe began as an infinitely compact fireball.
The Big Bang describes how this fireball grew to form all the stars and planets we see around us now. Because of its name many people think of the Big Bang as a kind of explosion that happened at some specific point in space, but this isn't correct, as the Universe didn't spring from one central ignition point

1) There are many observations that contradict it, for example:
no reduction in the surface brightness of distant galaxies: http://www.sci-news.com/astronomy/science-universe-not-expanding-01940.html
No stretching out of quasar light curves: http://phys.org/news190027752.html
Many more deficiencies listed here: http://www.metaresearch.org/cosmology/BB-top-30.asp

2) It relies on an unproven concept from GR, i.e. that space can "warp", which is itself contradicted by multiple observations (no grav. lensing above sun's atmosphere, no stellar einstein rings, no lensing of stars passing behind Sagittarius A*). See this lecture: http://www.youtube.com/watch?v=CnvOybT2WwU

3) The 3K microwave glow that is supposedly the residual radiation from the big bang is really just the thermal radiation emitted by the Milky Way's molecular hydrogen. See my answer: https://uk.answers.yahoo.com/question/index?qid=20140820172115AAviNPQ

4) It was originally devised by the Belgian Catholic priest, Georges LeMaitre, and named the "Theory of the Primeval Atom", and gained popularity with the american scientific community of the early 20th century largely because of it's parallels with the Genesis creation myth.

5) It is completely and utterly wrong and is likely to get consigned to the history books in the coming decades, along with Einstein's Relativity theories.

1)The temperature was homogeneously ever plummeting.
2)It followed the instruction list of pi.
3)It was instantaneous even to life.I suspect buildings too.
4)The planet Jupiter is actually a pre existent Big Bang eternal universe.
5)The Big Bang is still Big Banging.

The universe was once (14 billion years or so ago) much, much smaller than it is now.

The universe was once much, much hotter than it is now.

The universe has been growing ever since then and is still growing (and cooling).

The cosmic microwave background we observe in the sky is a relic of this early universe.

Physical models of the early universe correctly predict the ratio of Hydrogen to Helium (and other light elements) in the universe, the structure of the universe, and many other things we observe today.

Bubbleshead, all the "facts" are observations which support a Theory of the Origin of the Universe, not a known or observed event.

If I presented you with the same kind of question, changing it to:

List 5 facts about the existence of God..................

So, neither of us can get out ahead of ourselves without appearing really, really presumptive.

1) There was nothing before it, not even time
2) It ws the start of the universe, all matter and energy was created then
3) It happened between 12 and 14 billion years ago
4) It created energy until it "cooled" sufficiently for matter to form
5) No-one knows what caused it
