I read an article once (but cant remember which one) concerning one theory of the big bang. It was around an imballance between the four forces (gravity, electromagnetism, and the strong and weak nuclear forces) as gravity became the weaker force...

Hi, my first post!

For my 2pence worth, could it be that the universe and all of space has always existed, that maybe there was no start to it?

Unlikely as this would raise problems with infinities.

i.e. if it has been around forever then everything has happened already.
In fact everything would have already happened an infinite number of times.

You could say that, because time was created with the Big Bang, the universe has been around forever.

Could we ask the question, not how the universe was created, but why?

I thought for every action there was an equal or opposite reaction, so how could the original "action" that led to creation have happened?

Never thought of it that way.....very good point.

I will be pondering the implications of that for a while .

Hi all

I remember I watched somethind (Catastrophe I think) that said we only are here because we're lucky.

Dear al(L)
I was thinking about the possibility that Astro-Pete might have been right in suggesting the Universe was created by someone switching on a big particle accelerator.
My own theory is the Universe should really be infinitely old.
However, although the particle accelerator used to create the Universe was conceived an infinite time ago unfortunately they could not get the thing actually working properly until about 13.7 billion years back.
Does anyone know if the Large Hadron Collider is working yet, or if it ain't when it will, or might be working ?
Best of luck from Cliff

It has been repaired and they are presently cooling it to get the thing going again. http://news.bbc.co.uk/2/hi/science/nature/8309875.stm

Dear Joe
Thanks for the pointer in response to my question about a possible start date for the repaired LHC.
I note that the estimate in late 2008 for the repairs was £14 million but apparently have actually cost £24 million - assuming the forthcoming tests are satisfactory.
Best of luck from Cliff

No ! ......that would be philosophy not Astrophysics.

Apparently God plays dice !

According to Quantum Theory, it is possible for this not to be true.

What created the "Big Bang"

Post by johana »

Hi,
First I would like to know if anybody believes that the big bang was actually an explosion in space. I have a lot of comments about that.
Thanks,
johana

No it wasn't. What was the explosion in? It created space, it didn't happen in an already existing space.
