    Hey guys this is my first post so be kind . I was thinking that is it logical to think that before the big bang i.e. "nothing" that there was infinite gravity and the lowest kind of cold temperature possible. Now i was thinking that since pressure and friction give off energy that maby something happened with the cold and gravity that gave off some kind of friction or pressure thus creating a "spark" then the big bang happens?

    I thought that but then i thought maby these specific strings rubbed against each other and created the universe but i dont know. These are all just thoughts of mine and was wondering what you guys might think. Again i dont claim to be really smart so if it comes up as laughable i apologize

    One more thing regarding that there was "nothing" before the universe. isnt nothing something? (philosophy i know)

    We don't know that there was nothing before the Big Bang. We do know that whatever there was likely differed substantially from what we know of the universe today. There are several ideas, speculations really, being thrown about. According to popular accounts some researchers seem to feel that it may eventually be possible to learn something of what preceded the BB.

    Now, why would you think it is logical that nefore the big bang there would be infinite gravity and a temperature of absolute zero? I'm not saying you might not be right (though I have no idea just what infinite gravity would actually mean), but I really don't see why those two conditions are logical.

    From where I sit these two statements are just as logical: before the big bang the universe consisted of incandescent green parakeets, swiiming in marmalade. I don't think that's likely either, but I suggest there is just as much evidence for this as for your suggestion. What is needed is evidence, or a logical argument. Can you provide either of these? I'm not looking for proof, just what led you to the thought its infinite gravity and low temperature, rather than flaming parakeets in marmalade.

    It's good to think about things like this, but the more you can find out about the details of what we currently beleive the more likely your own thoughts will be able to get closer to the truth.

    I bring in temperature because it would make sense that there is always a temperature, more cold then warm because matter/energy had to be created from in that enviroment making cold the first temp. You go out into space and it is cold out there. emagine there where no stars or a source of heat. what is keeping cold so cold? thats how i came up with my reasoning for the temperature part. As long as there is no heat there is always cold.

    The part about gravity is something i thought of when finding out that all the way down in a black hole you find all sence of reality and physics dont quite match but its been mathmatically proven (so i have hear) that until we find a better solution that it also contains infinite gravity. i like to emagine that it would be like a hard, unmovable, invisible jelly. i know thats not the case anyways but the point is i see it as something outside the universe and that if there was no universe or objects it would just be gravity, unstreatched and in its orginal elastic form.

    hmm...now i wonder how ANYTHING could have formed from such infinite gravity.

    I'm currently with Hawking's view supporting the hypothesis of there was no before the big bang and that time was inaugurated with matter 'during' the big bang- isn't it shown by derivations of Einstein's equations of GR that time cannot exist in the absence of matter? I'm not too sure on that thought, please correct me if I'm wrong.

    But, anyway, as Ophiolite stated- it is purely speculation at the moment.

    But it also depends on what you think time is. Everyone has there own sence of it. To me it is hard to picture matter or anything all happening at one point because it feels like it or whatever you may think the reason is. There had to be some kind of cause. Now it is hard for me to say that because it goes against how i see how time travel works.

    I had another thought (my mind comes up with these idea's when i think of this stuff) that the universe eats itself and digest's itself. Let me explain. A black consuming all the matter and existence takes a part of the universe creating another universe at the end of it making the universe have multiple parts of itself by having one part of the universe swallowed to be used for another and it just keeps doing that. Like the snake eating its tail.

    Let me ask you this, Xan. If the universe is comprised of absolutely all there is, then what exactly is it which was "cold" or which expressed the effects of gravity ... before ... the universe even existed?

    Don't the concepts of cold and gravity relate to matter already in existence? What was cold? Where was that gravity acting? What was it acting upon? If the universe didn't exist yet, then I'm not sure it makes sense to describe things which happen WITHIN a universe. Do you know what I mean?

    i understand what your saying. hmm...i really cant think of much to say since it involves the outside of the universe but maby that infinite gravity black hole thing is saying that the edge of the universe has infinite gravity. Gravity is the thing im trying to figure out here as im sure everybody else is lol

    p.s

    if the edge of the universe does contain all that gravity maby that is the force accelerating galaxies to spread apart faster and faster?

    Hmm... I honestly don't know. Does the universe even have an edge? I wonder...

    There is no "edge" is any accepted models. An "edge" to 4-dimensional spacetime would be some sort of 3-manifold, which makes little sense.

    See? Who ever said the Socratic method is ineffective? Thanks DrR for ensuring clarity on this point. I largely suspected exactly that.
