what caused the big bang? how?

Answer 1

We don't know.

The best guess is that it was a knot of curved space that unkinked itself. There was no matter as we know this term that was present at the time. Just some kind of pure gravitational field with an enormous density of energy and curvature.

Answer 2

Well I have heard at the ten to the minus 43 seconds of the bang
matter and energy split.........or something.

Whats that mean?

I dont know, that is sorta something Steven Hawking said.

No, that's more than likely not what he said, it was MY take on what he said it was.

Here is my very low opinion of the big bang.

There are at least 2 universes.

Like a spring, matter and energy "spring" back and forth between these universes.

The "bang" part is when your "spring" is streaching INTO your universe.

The "LAST black hole" is when your univese is at an end.

Your spring is compressed. (therefore springing into another universe)

Matter and energy cannot be destroyed, only changed.

So, they switch from universe to universe

Like a AC wave, there is a positive side, and a negative side.

the BIG BANG is:

the BANG the positive side..

the Black hole, the negative side.

The universe was created instantly.....BANG!!!!!!!!!!!!!!!

The opposite reaction was much slower...Many balck holes.
over time.

How many parties have you been to that had a big bang, and the next day had many hours of clean up.

Bang! Quick and easy...expelling matter and energy into this universe.

Even in biology....life starts with a violent crash!

Sperm enters egg..then slowly things develop.


Now, I will say, that I have no Idea how things really work.

I am a welder for a living so astrophysics is pretty low on my education level.

Hey? how about you get Hawking or some other really smart person to tell you just how friggin really stupid my theroy is?

I'm just curious how far off my idea is!

Answer 3

n physical cosmology, the Big Bang is the scientific theory that the universe emerged from a tremendously dense and hot state about 13.7 billion years ago. The theory is based on the observations indicating the expansion of space in accord with the Robertson-Walker model of general relativity, as indicated by the Hubble redshift of distant galaxies taken together with the cosmological principle.

Extrapolated into the past, these observations show that the universe has expanded from a state in which all the matter and energy in the universe was at an immense temperature and density. Physicists do not widely agree on what happened before this, although general relativity predicts a gravitational singularity.

The term Big Bang is used both in a narrow sense to refer to a point in time when the observed expansion of the universe (Hubble's law) began — calculated to be 13.7 billion (1.37 × 1010) years ago (±2%) — and in a more general sense to refer to the prevailing cosmological paradigm explaining the origin and expansion of the universe, as well as the composition of primordial matter through nucleosynthesis as predicted by the Alpher-Bethe-Gamow theory.[1]

From this model, George Gamow was able to predict in 1948 the existence of cosmic microwave background radiation (CMB).[2] The CMB was discovered in 1964[3] and corroborated the Big Bang theory, giving it more credence over its chief rival, the steady state theory.[4]

Answer 4

We can only theorize about it but before it started there was nothing.
There are two types of nothing.
When something begins and ends ,the end must be a state of eternal non existence,an incident that comes and goes.
..When the universe ends it will never happen again.
Before it started there was nothing,but there had to be a potential and the potential had to be finite or nothing could have happened.
In some way a single space-time pulse was initiated.
This single space-time pulse evolved into a universe and us.

Answer 5

1. Doesn't matter; I bet nobody heard it! If no important people heard it, it was no big (bang) deal!

2 .. but is likely "the damn kids next door", as one of the good answers here.
The credit is all his/her! I am only subscribing to this!

Answer 6

Probably some physical interaction within the meta-universe.

Answer 7

Its just a theory. No particular proofs and scientific evidences.

Answer 8

Those damn neighborhood kids and their fire works again.
