You're like some kind of super... thing. Using the literal definitions of words is also a bad idea, as science generally defines things very precisely (something I don't think you've taken on board; anything empirically unproven is a postulate, not a theory) and the two usually don't aline in any brilliant or argument winning way. Re: the original question. I've not seen any way for two multiverses to interact after their formation, which means that, even if this is true, there is no way we can possibly measure it, so the only correct scientific thing is to assume that they don't exist. They're perfectly harmless though, so do what you like with them. They make for a decent scifi premise. Link to comment Share on other sites More sharing options...
ydoaPs Posted July 8, 2004 Share Posted July 8, 2004 how can there be more than one universe. define a universe if it isn't the extent of the four unfurled dimensions? I am not being sarcastic or anything, i just want to know. Link to comment Share on other sites More sharing options...

I am not being sarcastic or anything, i just want to know. By there being... more than one. The leap of faith (as it were) from 0 to 1 is much harder than from 1 to many.

ydoaPs Posted July 8, 2004 Share Posted July 8, 2004 i dont understand how there can be more than one everything(unless u r talking about brane theory in which there is a four dimensional "reality" less than a milimeter away separtaed from us by two dimensions) Link to comment Share on other sites More sharing options...

admiral_ju00 Posted July 8, 2004 Share Posted July 8, 2004 Speaking of which, since I'm not into physics(beyond a mild curiosity) but can you tell me what the 11 dimentions are in the superstring theory? Link to comment Share on other sites More sharing options...
ydoaPs Posted July 8, 2004 Share Posted July 8, 2004 what you are talking about is the four extended dimensions. and is that or is that not everything? therefore universe lives up to its name. there are two configurations for the dimensions. calibi-yau manifolds or brane theory. brane is separated a little bit by if u want ten or eleven dimensions. but it goes like this: there are two four-dimensional "realities" less than a milimeter apart separated by two (or three depening on the string theory) dimensions Link to comment Share on other sites More sharing options...
JaKiri Posted July 8, 2004 Share Posted July 8, 2004 Speaking of which, since I'm not into physics(beyond a mild curiosity) but can you tell me what the 11 dimentions are in the superstring theory? The 4 main ones, then 7 more. The 7 more are postulated to be as a Calibi-Yau space, which can be explained as follows. Have you heard of flatworld? The thing Einstein used to make a comparison of 4-D space? It involves little 2 dimensional beings on a 2 dimensional surface. Lets take one of these 2 dimensional beings and put it on a thin pipe. In one direction, the pipe is infinite (like our time/distance dimensions). In the other direction however, it's curled up very tightly (if you see what I mean); it's a finite dimension. You can only travel a short way in it before you come back to yourself. This dimension is like the 7 new ones postulated by several of the superstring postulates.

admiral_ju00 Posted July 8, 2004 Share Posted July 8, 2004 I though it was something like: space, time, gravity, etc Or am I way off here? Link to comment Share on other sites More sharing options...
JaKiri Posted July 8, 2004 Share Posted July 8, 2004 I though it was something like: space' date=' time, gravity, etc Or am I way off here?[/quote'] Gravity isn't a dimension, it's a force. Dimensions are distances, that's all. (Admittedly that's shoehorning 'Time' into the distance category, but that's a chance we'll just HAVE TO TAKE!)

admiral_ju00 Posted July 8, 2004 Share Posted July 8, 2004 Ok, sry about the gravity thing. But from what you guys said that these 7 extra dimentions are Calibi-Yau space, and they are all the same? Or is there (any hypothesised) variations within the Calibi-Yau space? If so, they why is there a need for 7 of the identical items, more or less?

ydoaPs Posted July 8, 2004 Share Posted July 8, 2004 there are infinite variations of calibi-yau space. it depends on the theory. it is to cancel out the tachyon frequencies Link to comment Share on other sites More sharing options...

admiral_ju00 Posted July 8, 2004 Share Posted July 8, 2004 ...and the fact that "this word means X so therefore Y can't happen" is just stupid. Uhm, I guess this was addressed to me. I was basing it on this quote: M-Theory The standard model was designed within a framework known as Quantum Field Theory (QFT), which gives us the tools to build theories consistent both with quantum mechanics and the special theory of relativity. With these tools, theories were built which describe with great success three of the four known interactions in Nature: Electromagnetism, and the Strong and Weak nuclear forces. Furthermore, a very successful unification between Electromagnetism and the Weak force was achieved (Electroweak Theory), and promising ideas put forward to try to include the Strong force. But unfortunately the fourth interaction, gravity, beautifully described by Einstein's General Relativity (GR), does not seem to fit into this scheme. Whenever one tries to apply the rules of QFT to GR one gets results which make no sense. For instance, the force between two gravitons (the particles that mediate gravitational interactions), becomes infinite and we do not know how to get rid of these infinities to get physically sensible results. http://www.damtp.cam.ac.uk/user/gr/public/qg_ss.html So in light of the above quote, is the word, idea, concept(whatever) of Infinite IS or IS NOT meaningless in Physics?

JaKiri Posted July 8, 2004 Share Posted July 8, 2004 Isn't a value that is Infinite (especially in Physics) is meaningless? Infinite variations. It's just one of them. A calibi yau space is just a term for some things grouped in a way mathematically devised by Calibi and Yau. Link to comment Share on other sites More sharing options...
