Because Einstine and Minkowski showed that space and time were four dimensions. String Theort has extended from this original conlcusion, therefor, STRING THEORY DOES NOT WORK IN THE ORGINAL FOUR DIMENSIONS OF RELATIVITY, BUT RATHER THAT THEY NEED AND REQUIRE MUCH MORE.
This is absolutely not true. General Relativity is consistent in ANY number of space and ANY number of time dimensions.
I'll explain this ONE MORE TIME Ben before i go, then after this, make a final comment and lock the thread. You said... ''This is absolutely not true. General Relativity is consistent in ANY number of space and ANY number of time dimensions.'' YBut my point was, and hence the CON, string theory cannot. Therego, string theory works only in dimensions extended of relativity. It is inconsistant in the original four alone. Why can't you understand this>?
How many master's theses have you written on String Theory? I've written one Please Register or Log in to view the hidden image! Look, the fact that string theory requires extra dimensions beyond four is, in and of itself, a con. String theory PREDICTS the dimension of space-time, which is more than you can say about general relativity. Ten/eleven dimensions can be taken as a firm prediction of string/M theory. GR makes no similar prediction.
Nope. Written none. To be quite frank, i wouldn't waste my time. I'd rather write a book on Aether Wave Theory Please Register or Log in to view the hidden image!:bugeye: But as for the rest, yep... no probs.
No... what i do agree with is that we had crossed wires, for when you said, ''Look, the fact that string theory requires extra dimensions beyond four is, in and of itself, a con,' is more or less a much more coherent configuration than what i was letting on. As for you latter comment there: ''is not true, and moreover string theory is actually better than GR in this regard?'' Why do you say this... Its not that i am arguing, just interested.
I should have said (and thought I did) this: String theory PREDICTS that space-time should have ten or eleven dimensions. Well, like I said, string theory PREDICTS that space-time should be four or five dimensional... GR doesn't do this---it is consistent in ANY number of space and time dimensions.
String theory predicts that spacetime if 'FOUR,' or five... Sorry... I thought string spacetime needed to be ATLEAST, five. Wouldfour be inediqaute, or, is it that one of the theories predicts no time dimension and four space?
No---string theory predicts a ten or eleven dimensional space-time. The fact that we observe four dimensions means that six or seven of the dimensions must be compact.
Was this just wee typo then? ''Well, like I said, string theory PREDICTS that space-time should be four or five dimensional... '' As for the compactness, i think currently we can probe spacetime to 100 micrometers, and i think the theory predicts a visible dimension at 200...
ummm, can you link to the thread, because I can't find it... Either way, if I did say this, then it is a typo.
Its alight. We all make mistakes. Me especially... Please Register or Log in to view the hidden image!Please Register or Log in to view the hidden image!
So, back to the point: String theory predicts a dimension for space-time, which GR doesn't. You may hate the fact that that prediction isn't four, and many people do. But string theory predicts something, where GR doesn't.
