Nacelunk Posted March 22, 2006 Share Posted March 22, 2006 Here is the question - How/why/when has Universe appeared? The only thing i can think about is that It has appeared from The Nothing You will say that was all about the singularity but from what, then, the singularity appeared? If our Universe appeared from nothing (and without a purpose/reason), then I can say that there are infinite number of "Universes" (in our perspective) appear every "moment" with totally different laws of nature, logic, constants etc which we are never gonna understand, because we weren't born there and having different brain. Very probably that all the universes aren't interconnected so technically we can say they all don't exist (in our perspective) therefore we don't exist for some other civilization in another "universe". What do you think about it? PS Sorry for my english - I am only 1.5 years in Canada Link to comment Share on other sites More sharing options...
Moonquake Posted March 22, 2006 Share Posted March 22, 2006 The universe need not appear from anything as the concept of 'before' and 'after' is irrelevant if you take into account that time is merely a component of the universe itself. Link to comment Share on other sites More sharing options...

Moonquake Posted March 22, 2006 Share Posted March 22, 2006 The 'beginning' is the 'act or process of bringing or being brought into being' which fundimentally requires the concept of time, yet time is part of the universe and didnt exist 'before'. as there was no 'before' as this is defined as 'earlier in time'.

Nacelunk Posted March 22, 2006 Author Share Posted March 22, 2006 You mean - if there was no "time" then nothing could be "brought into being"? Link to comment Share on other sites More sharing options...
Moonquake Posted March 22, 2006 Share Posted March 22, 2006 Basically I suppose. Link to comment Share on other sites More sharing options...
The Peon Posted March 22, 2006 Share Posted March 22, 2006 According to my understanding of string theory, universes pop into existance all the time, so our current universe was made from the string "material" that allready existed. A better question would be where did the strings come from... Link to comment Share on other sites More sharing options...

BhavinB Posted March 22, 2006 Share Posted March 22, 2006 ^^ supposedly the collision between membrane strings might have created the universe as we see it and we're in one of the membranes. But ofcourse all this is untestable. Rather there is no evidence that we can detect anything from before the 'big bang'. Link to comment Share on other sites More sharing options...
Nacelunk Posted March 22, 2006 Author Share Posted March 22, 2006 I have one more question - why is the Universe so harmonic? I mean why isn't it just a bunch of molecules located in regular intervals without any аttributes of life? That singular point must have had perfectly definite "push" to have, in result, our universe even with possible existing of life Link to comment Share on other sites More sharing options...
Nacelunk Posted March 22, 2006 Author Share Posted March 22, 2006 Basically I suppose. But how come our Universe actually exist? There was no "time" before the Universe appeared because the "time" is just one of the aspects it. Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted March 22, 2006 Share Posted March 22, 2006 I have one more question - why is the Universe so harmonic? I mean why isn't it just a bunch of molecules located in regular intervals without any аttributes of life? That singular point must have had perfectly definite "push" to have, in result, our universe even with possible existing of life When the universe was much, much smaller, and much, much denser, random movements of molecules (which always are occurring) caused some segments to be a bit more dense then others. Once the universe expanded, that effect grew, and the universe became "clumpy" as gravity pulled these areas together even more. Link to comment Share on other sites More sharing options...
Nacelunk Posted March 22, 2006 Author Share Posted March 22, 2006 random movements of molecules (which always are occurring) I thought singularity is a very little (infinitly) point which is, therefore, much more little than an ordinary atom Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted March 22, 2006 Share Posted March 22, 2006 Yes, that's the way it was in the very beginning. But as the universe expanded, bits vibrated and moved around. Link to comment Share on other sites More sharing options...
Nacelunk Posted March 22, 2006 Author Share Posted March 22, 2006 And what made that singular point expand and convert to molecules? Link to comment Share on other sites More sharing options...

Nacelunk Posted March 22, 2006 Author Share Posted March 22, 2006 OK, but how have all the galaxies, stars, quasars, black holes, etc, appeared? Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted March 22, 2006 Share Posted March 22, 2006 From those little dense areas in the gas at the start of the universe. The dense areas had more gravity, so they pulled more matter towards them, which caused them to have more gravity, and so on. Eventually (over millions/billions of years) the clumps got big enough that they formed planets and galaxies. I should point out that I'm a bit out of my area here; I'd like a physics expert to take over, please. All I know is what I read in The Elegant Universe.

Nacelunk Posted March 22, 2006 Author Share Posted March 22, 2006 If you know something about chemistry - why are there so many elements in the World? (why isn't there just one element? (in periodic table)) Link to comment Share on other sites More sharing options...
Xyph Posted March 22, 2006 Share Posted March 22, 2006 Stars create heavier elements through nuclear fusion. Link to comment Share on other sites More sharing options...
YT2095 Posted March 22, 2006 Share Posted March 22, 2006 If you know something about chemistry - why are there so many elements in the World? (why isn't there just one element? (in periodic table)) once upon a time, there WAS only one element, Hydrogen. and as Xyph said, the reaction in Stars creates others. Link to comment Share on other sites More sharing options...
Klaynos Posted March 22, 2006 Share Posted March 22, 2006 IIRC Supernovers are a big part of creating elements heavier than iron... Link to comment Share on other sites More sharing options...

[Tycho?] Posted March 22, 2006 Share Posted March 22, 2006 once upon a time' date=' there WAS only one element, Hydrogen.and as Xyph said, the reaction in Stars creates others.[/quote'] I believe when the first atoms were formed after the Big Band helium was formed along side hydrogen. There was just more hydrogen. Link to comment Share on other sites More sharing options...
