Nothing that I'm aware of. I've heard of a gravity experiment done on a nanoscopic scale a year or two ago, searching for gravity "leaking" into higher dimensions. No variance from expected gravity was found. Since then, I've not heard of any new developments.
No, just a whole lot of criticism. It's not falsifiable, empirical, or anything that makes a valid scientific theory, really. It has about as much scientific relevance as banana pudding.
It's a 20 minute long video that I think I linked you to a while back, but I don't remember if it was you or someone else. It's an interesting video, if not three years old. >_>
I love this stuff. The idea that we may be able to use gravitons to comunicate with other universe. Or the cause of the big bang being the collision of 2 strings that expanded along an 11th demension. I am pretty sure that's what they meant. It is hard to understand.
Last time I researched (2 days ago) the string theory is actually....five different theories. Each equally credible. Hence the reason you hear it being called the "Super String Theory" sometimes. Considering there is no possible way to test the string theory, those five valid string theories just linger there. They all require different conditions (hypothetical particles, numbers of dimensions, etc.,), but there is no way of finding out which one is right. Unless someone can think up and ingenious experiment to rule out 4 of the 5 theories.
So all in all, I don't think the string theory will be moving anywhere sometime soon.
Thanks Zatch! My sophomore ears had never even touched this subject and now I'm going to be up until four in the morning reading, watching videos, and thinking about this theory...
Michio Kaku talks a lot about the string theory in his new book, the Physics of the impossible, i think you would like the book. you should check it out.
I don't suppose anyone has read (or at least heard of) "Ten Luminous Emanations" by Yehuda Ashlag? He deals with the ten compartments, veils, dimensions, whatever you want to call them, which as far as I understand are the basis for the String Theory. correct me if I'm wrong. I believe it's a set of seven books. Then again, considering they're all in Hebrew... I doubt anyone actually has.
Since this is the "General Discussion Forum", you should have talked about generals, or GE or something relating to what's general or not general. At least, that's what I think.
@ khurram_89 Yeah, I'm reading through "The Elegant Universe" right now. It's pretty interesting stuff. The guy is a great writer, and he makes everything relatively easy to understand if you have a basic knowledge of physics.
