The analytical structure underlying the spinorial theory can be represented visually. The structure is a Xi-transform which moves between the three spaces in the directions given by the bendings of the upper case Greek letter Xi. The distorted square ...
The analytical structure underlying the spinorial theory can be represented visually. The structure is a Xi-transform, which moves between the three spaces in the directions given by the bendings of the upper case Greek letter Xi. The distorted squares represent the wave operator. The product of a wave operator and a Xi transform, taken in any order, is zero. Image credit: Erin Sparling.

In a recent study, mathematician George Sparling of the University of Pittsburgh examines a fundamental question pondered since the time of Pythagoras, and still vexing scientists today: what is the nature of space and time? After analyzing different perspectives, Sparling offers an alternative idea: space-time may have six dimensions, with the extra two being time-like.
