Philosophy Of The Cosmos - Big Bang And Black Holes
So, I was thinking. Black holes potentially, theoretically, are able to transcend universes and dimensions, and it still makes more sense for something to come from something, rather than nothing.
So is it possible that the Big Bang actually resulted from the singularity of a black hole? The black hole breaches _something_, reaches just a single point where maybe the density is too much, and the very tip, which is so very full of matter, explodes, causing the big bang, and countless universes?
Just a thought.

Something rather similar I think was mentioned in Stephen Hawkins "A Brief History of Time", where he points out to a theory, where the idea is that we life in a universe with many parallel universes and when they colide between each other it could then have set of something like the Big Bang. But this has not been proven.

The way I've been led to understand the Big Bang in a conceptual sense goes something like this: In the beginning, the loss of supersymmetry created the heavens and the earth, and from that moment onwards, the "balance" the Universe exhibited at the "beginning" breaks down in ever greater degrees; forces break apart, symmetries are broken, and only now, through application of mathematics (or revelation of mathematical laws??) are the truly unified natures of these forces and particles understood.
Indeed, one could say that the universe was created ex nihilo: The perfect balance, or "oness" of forces and particles essentially rendered them "nothing" in that they "cancelled" each other out. The loss of this nothing, is, in a sense, the reason for our existance and the existance of the Universe. It's a kind of counterintuitive nothing, though: a potent darkness, not merely an absense but a presense. At least, that is how our human brains might conceptualise it.
A question: Where does the idea of entropy fall into all this. Has entropy got anything to do with the split, if you will, of forces?

We'll cover entropy in lectures later. The short answer is that entropy is not a fundamental concept; it's just a way of summarising other aspects of physics. Whether it has anything to say about the beginning and end of the universe is something I'll talk quite a lot about in lectures.
[[black I have a question which may be relevant to this discussion. It's seems really trivial but doesn't matter how/how much I think about it I can't quite understand it. I've been taught that the big bang was an explosion OF space, not IN space- which I find…a little bit difficult to grasp. Even if there was nothing before everything, shouldn't there be something that trigger this explosion of space? Did space just collapse on itself and became nothing then suddenly explode out into the space again? But it still nags me that SOMETHING must have caused the big bang. You can see that I'm totally confused.
Thanks for clarifying :))

That's a good question, Ly, and the answer is … we don't know! Dayal will give some speculations about this later.
