A new wrinkle for time

Are there six dimensions to space and time? Perhaps so, according to a newly published mathematics paper mentioned at physorg.com. "Up until now," the site editor says, "most theories concerning extradimensions have dealt with space-like rather than time-like dimensions...." (my emphasis)

I'm not close to getting the math, but the article reminds me of efforts to understand cellular biology that eventually led Francis Crick to conclude that the double helix was the structural basis for DNA, or the help that topology provides in understanding the shape of the extra dimensions proposed by string theory, or, lastly, how the ancient and highly technical practice of origami might lead to medical devices that unfold inside the human body.

I just find it interesting that shape, in this case, a spinorial geometry, might also be applied to the idea of time.

Have a great weekend,
