What’s String Theory you ask? What’s it all about?
I don’t know what it is, really. You can read a lot about it on Wikipedia, or watch a lot about it on TV or the internet.
It’s beautiful, but you can’t test it, see. It ain’t a “theory” yet, because of that, just mathematical masturbation (not my words!). Then, that’s what they probably thought Newton was doing in his attic, too, at the time. Look at him now, will you, explaining the universe and everything even though he’s long gone!
So, yeah, I mean, no, I dunno.
