A layman's questions about universes

I am just wondering if there is a possibility of an infinite universe? What does science say? I really don't know much about this, and doubt I can grasp any technical input.I am guessing most would agree that this is a finite universe? Big Bang and all. Don't laugh.Q1. Could this universe ever become infinite? (Your laughing again.) I heard something about an implosion once? Or something about losing gravity??...Q2. If other possible universes existed with a Big Bang beginning, does that mean there would be no infinite universes?Q3. If there is possibly an infinite universe, would our universe reside inside that infinite universe?Q4. If these continuous Big Bangs happened, where would they be happening? Would they be happening in another infinite universe, or would they be coming from "nothingness"? How could nothingness be "outside" an infinite universe?Q5. Would nothingness be infinite? Could our universe reside "inside" another universe?You may answer any question/ no questions.

To be honest I have no conclusions whatsoever yet Jar. Just questions. Oh yeah, I never thought of that. Clever boy. I am wondering though, if there are "other universes", then are we in an infinite one? Can't wrap my brain around it you see.

I'm glad you said that. You answered it though. Here's what I meant; I was referring to "nothingness" - as being the "place" where the Big Bang came from, a "larger structure" I suppose. So please DON"T give no mathematics. Yet how can a larger structure exist outside a boundless infinite universe? That puzzles me. Maybe my mind simply can't cope with that thought. I suppose I meant the universe with no boundary. Infinite without one. You see, I asked too many questions int the OP. Yet you have shown that this is far from simple.I thought that if another universe was infinite (no boundary), then our universe must exist inside it. Afterall, if it's literally forever, then can our universe exist outside of something which is boundary-less. I suppose that you have shown that correct with the example of 0 -1. Infinite stuff inside, yet a boundary.Now let's imagine a Big Bang happens inside the "larger structure", surely a Big Bang can only create an finite universe? As I remember, the Big Bang was an explosion of space/time? Therefore it grows. Jar said that a "growing" universe can never be "infinite" yet could grow infinitely. Is there a possibility of an infinite (bound) universe when a Big Bang occurs? Because if Jar is right, then surely it cannot ever achieve "infinite" stuff inside?I suppose I could pedal infinitely on a bike, yet I will never achieve infinite pedalling. My pedal tally would grow and grow, and if I was immortal I could lterally pedal forever, yet I suppose my number of pedals would never achieve infinity.Thanks for the reply anyway Rrhain, sorry for my late response.This message has been edited by mike the wiz, 06-21-2004 04:14 PM

Fair enough. I doubt I'd understand the mathematics anyway. Didn't Eta say that Big Bangs can't create infinite universes? Maybe I am wrong, but there seems to be some conflicting opinions. Am I then right in assuming that scientists could also disagree with one another concerning this issue?Being a layman on this whole thing, I'm unlikely to get this stuff. I suppose this debate is speculation really. As surely there is only evidence of this universe. The "bigger structure" and multiple Big Bang's, I'm guessing there's no evidence for.So basically I'm going to now just read this topic and see what happens with Buz and the others.Thanks for the replies. I now understand that this is a complex thing.

I agree, it is nonsensical and meaningless to say "you idiot" rather than supplying a refutation.As for your post to me, I am sorry I've been "over-posting" in numerous topics, but I do like your idea that the universe is "everything" in that, there is only evidence for one fine tuned universe which contains well, everything.Regards, Mike.This message has been edited by mike the wiz, 06-22-2004 09:47 AM

It means words are the things that get in the way of what I want to say. Lol. That's all I mean really, that basically we only have evidence for this universe. I know Buz is getting a lot of flack but really, all he's saying is that there is only one universe - this one, which is also scientifically sound.So these multiple Big Bang's seem to be a bit speculative. Even if I am the one causing this induced speculation infiltration relation particle process of excess. Now let me lurk.
