Why is space three-dimensional?

If this is right then it means string theory is wrong (as it requires 10 dimensions)...man that's going to really annoy a lot of other physicists (and mathematicians)... I hope they understand the gravity of that assertion :-)

Beware the dangers of commenting without reading the article first:

The proposal still leaves room for higher dimensions to have occurred in the first fraction of a second after the big bang when the universe was even hotter than it was at the critical temperature. Extra dimensions are present in many cosmological models, most notably string theory. The new study could help explain why, in some of these models, the extra dimensions seem to have collapsed (or stayed the same size, which is very tiny), while the 3D space continued to grow into the entire observable universe.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason? Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful? --Zachris Topelius Training a telescope on one’s own belly button will only reveal lint. You like that? You go right on staring at it. I prefer looking at galaxies. -- Sarah Hoyt

I read the article but it went straight over my head - which does prove there are at the very least 3 dimensions. My post was only a vehicle to introduce a "gravity" pun.
