00:05 Does that sound like a coincidence?
00:06 It does not.
00:07 Yep.
00:08 That's what I think.
00:10 So, so did we do it? Did we just solve string theory?
00:14 Oh, I appreciate your enthusiasm,
00:18 but this is not the sort of thing we can figure out in a night.
00:20 People have been stuck on this for decades.
00:23 What? Decades? Really? It's a string. How hard can it be?
00:28 It's straight, it's in a loop, it gets knotted up with other strings.
00:31 Well, actually, there are no knots in anything greater than four dimensions.
00:35 Unless...
00:38 we get around that by considering them as sheets.
00:42 You know, topologically speaking, that has a lot of interesting possibilities.
00:47 See? How long did that take me? Like a minute.
