What was there before the BIG BANG?

Devil's advocate here, but;

(and I'm not some hippy, more of a philosophiserer)

How can you be sure that a physical universe exists? If 'something', essentially being created from 'nothing' seem implausible, then why can't it be that the whole universe and existence is a subjective view, and that actually 'reality' is a construction of our psyche and subconscious mind?

Wow, deep for this time of night. :p
 
I think the most widely accepted theorem is that before the big bang there was one ray of light/superstring, that wobbled out of time. This then caused a singularity, which, due to the apparent lack of gravity before the big bang, expanded. Massively.

This ultra tiny ball of energy then continued to expand, and the energy warped the spacetime around it, forming gravity. The gravity coalesced two types of substance together - Matter and antimatter. Except the antimatter didn't coalesce properly, as rather than exuding gravitational fields when formed exuded antigravitational fields.

It has been been hypothesised that maybe there was a very tiny amount more of matter than antimatter (or something to that extent) which meant that even though as matter and antimatter collided (causing annhialation - a release of pure energy [which seems to support the idea of matter and antimatter being at base the same thing]) the matter won out.

Of course it isn't that simple, as antimatter obviously still exists (A-level physics whooo :D) but as I said it is a theorem.

Now I could have gone into a lot more detail, and used equations and more long words and shizzle but that would be no fun, hey :p

/Physics lecture ;)

Your subjective view and mine are not the same, we are both however observing something. That something does certainly exist. The internal view we create ourselves in order interact and thus operate within the universe, and actual reality are not the same thing. Don't confuse them.
 
I remember watching a documentary a few years ago that refered to it being the result of multiverse theory.... If I remember correctly something about to other universes coliding an forming ours

Not a hippy view at all - in fact one of the major theories in Philosophy. It's called Idealism and it states that everything we perceive depends the mind for its existence and so we can never be totally sure that reality exists independently of the mind, or at least that reality in its "pure form" might not be what the mind makes it out to be.

As for the Big Bang, I have no knowledge about it I'm afraid.
 
This was talked about on Dr Michio Katu blog late last year they were on about Can a Universe Create Itself Out of Nothing?

some dude says Creation from nothing is illogical.

I said how is it,this is the reply he gave me lol..:confused:

The transmutation of an already present form ..such as energy...not as currently understood ... but existing beyond measure...Our Universe is I believe very infinitely small as compared to the expanse of the vast void that makes up th...e extended cosmos...Imagine a single grain of sand in our known universe as a comparison & that is probably not even close to a real actual reality for size...We are currently looking at the universe as formed...Galaxies full of stars..planets & moons. Gasses, dust, radiation of all types gamma. microwaves, x-ray, UV, inferred & all light spectrums...etc. What would it be without all these properties? What would it look like? If devoid of all these things! Measures we now take are only of that which we are surrounded by & within those property margins. The Fabric of space & time...before both? A void infinite and devoid. Cold...beyond the measure we could ascribe as cold. MIT did some experiments where they attempted to reach Absolute Zero in a Universe where there is temperature and noted the effects on matter...Matter seemed to deform and break down as temps dropped... a hypothesized wave form for energy as is thought of as basic String Theory...
So now Imagine Infinite Zero...the absence of all the above aforementioned...what would that energy be? I believe that this is the all the matter and fabric of our Universe in it's most ...and for lack of a word... primordial state. Energy has polarity and by this mechanism I hypothesize is The Origin of the Big Bang and our Physical Universe.
However the vast amount is still in flux and yet uneffected...this may be what is responcible for the continued spatial expansion and the illusive source of Dark Matter it is the pre flux matrices itself.:

The universe is just another layer of container that lies inside another container, and that which lies inside an even bigger container. Go the other way and look at the inner space, we are looking for smaller and smaller particles.

Everything is just a container for something else.

so the Doppler effect has kinda proved the universe is expanding like a baloon - which is great, but rewind about a trillion years until it was the size of a pin head, and then a few more years..... there would be nothing...... no elements....no light....no darkness..... no time............nothing........literally nothing.............. it does not compute.

but then how could there be nothing? because even an absence of something is.....well something.

anyone got a spin on this?
