ugh; this video is terrible, wrong, and confusingwhen they say the dimensions are "small" and "tightly folded" they mean the following:consider a really skinny soda straw. to a bacterium, it feels like a sheet of paper (2-dimensional) it can traverse around the straw (one dimension) and up and down the length (the other dimension).On the other hand, if you "zoom out", the straw acts essentially like a line. Perhaps it's only a few microns wide, we couldn't very easily detect the dimension around the straw, and we are left with only one apparent dimension, the length up and down.Relating to strings, if there was a very very thing and tiny string tied around straw by the bacterium, it would certainly see it as a loop, whereas to us it would merely look like a point along the length of the straw and for most purposes of *our* scale it would act like one as well.Now rather than having something 2-dimensional, and "folding" one of the dimensions into a little (1-dimensional) circle to obtain something that *appears* to be 1 dimensional; string theorists propose that the universe is actually 10 dimensional (not counting time, it's a bit different; one-way and all..) and 6 of the dimensions are "folded" into a little 6-dimensional manifold (Calibi-Yao manifold) leaving only 3 of the dimensions visible/measurable to us. Don't try to picture it directly...Please don't listen to the crap this guy is hocking. (see my post below)
When it comes to science, I would rather have a slightly confusing explanation of reality than a crystal clear explanation of an inaccurate fantasy. At least, when you put the work into actually understanding the real explanation, you're closer to the truth rather than further from it. Thanks chjb.
Yes, string theory predicts 10 or 11 (or 26) dimensions, but there is still debate as to the *where* the dimensions are. The explanation in this video is but one of two competing theories. The other is that the other dimensions are simply too small to observe - as a three dimensional garden hose appears like a one dimensional line from fall away. The different ways the extra dimensions wrap around themselves are described by "Calabi-Yau spaces."

@mcl768Actually we see in 3 dimensions. Depth Perception from having two eyes. Aside from the fact that a 2d flatlander wouldn't be able to see at all (the "line" they see wouldn't be there at all. They couldn't see it.) If they COULD see the 1D (which is mathmatically impossible, even a line has a 2 dimensions) and they had two eyes, they would most certainly be able to see in two dimensions much the same way we see in 3D thanks two our two eyes. Someone with only one eye would be able to see in only 2D.
"But didn't they show in the BBC video how there's probably 11 dimensions and not just 10? If 10 is everything then 11 is... another everything to everything?"Dude YOU ARE BLOWING MY MIND DUDE!!!!!

I'll never understand this until I'm there. Or am I already there, except on a path folded so I think I'm in the 3rd dimmension...?
