    If the universe started when two sub atomic particles collided, then why hasn't another universe started in the last 13 to 14 billion years? It would seem that more particles would have collided by now forming a new universe but none has done so. Where exactly did those sub atomic particles come from anyway? Did they just form on their own or ???

    What makes you think "the universe started when two sub atomic particles collided?" If you're referring to the LHC's media hype, the LHC is not going to recreate the big bang itself, but the energy that was seen a little after the big bang.

    So what do you think created the universe then, many people believe that is how it all began.

    It's not something that current theory can answer satisfactorily so what people believe is pretty much speculation. String theory is the most prominent theory of quantum gravity at the moment and there are some ideas in it that there is a "hyper-verse" that is full of branes. Every so often these collide, creating a universe. There are quite a few problems with this type of model though, and my understanding of them is far from complete. The question of what came before the BB and what caused it may be a question we can never answer, at least scientifically.

    If there are two particles and nothing else, then that's the universe.

    The question presumes that the universe 'started', i.e. it has a starting point in time. Alternatively, variants of the BB theory do not have a 'starting point', and the universe has always existed; merely evolving over time to what we now see.

    Yes and no.
    He writes that, yes. But then he goes on to say there already was something.

    No, but I do know the definition of the word 'universe'.

    I'm not sure what point you're trying to make here though.

    universe is everything.

    when there was nothing, was there still a universe?

    What do you mean 'still' ?
    And, no, nothingness is not a universe.
