Something from Nothing

When people like Krauss and Hawking talk about a universe from nothing or it makes no sense to talk about before the Big Bang they are being a bit deceitful. They are being deceitful because while they believe it is possible maybe even probable that our particular X, Y, Z, + T observable universe began with the Big Bang they also believe there was probably a background something that it came from.

String Theory is currently the leading theory on what that something is. Krauss even believes that if String Theory is true then a multiverse is probable. If a multiverse is true then there are other spacetime universes besides ours.

String Theory isn’t the only possibility though, and the Big Bang is far from confirmed. Other possibilities include our universe is cyclic. expanding and collapsing over and over again. Another possibility is it could be the result of the collapse of the false vacuum of a previous higher energy vacuum.

Krauss himself talks about some of this in this short article about the limits of knowledge.

String theory appealed to me when I first read it. I like aspects of all the main theories, and see plenty of overlapping.

Science wants to have a formula that accounts for matter which only considers what is observable or measureable, even if only in theory.
Which is somewhat consistent with the practice and application of scientific thinking.
While one theory will account for one phenomenon, it will fail where another doesn't. You would think that if we picked the best of each theory we'd have a better picture.

Explain how god created the universe without quoting the Bible.

Good question, but we are discussing the treatment of the topic by the scientific and philosophical communities.

I know some people have fearfully belched out "sky god," so I'll wait until their fever dies down and they start communicating without being so immotive.

My response to your question belongs in the religious section, because I go by what the Bible contains.
But in this section, I am willing to explore the way people handle these topics, which they have pretty much covered.

emotive.     There are some grammar ninjas in here.  (Some people use grammar nazi but I'm not any kind of nazi.)
"sky god" is belching out emotion?  LOL.  Hey at least they used the term god.  I tend to think "imaginary friend" is much better.
But if you want emotive, then I can wrap "imaginary friend" in a whole bunch of other fun and appropriate adjectives.  
If you start a discussion about the big bang, origin of the universe, and general physics, (cool!) the silly old book of ignorant fairy tales 
has no relevance or place. 

But continue.  This is fun reading.  At least you haven't been calling people stupid and claiming that they deserve eternal torture and crap like that.  You're improving.
