I personally think that the split-octonions[1] hold promise for physics. The subset of the split-octonions where the i, j, k, and l components are 0 have a metric that is similar to that of Minkowski space[2]. (t + xli + ylj + zlk) * (t - xli - ylj - zlk) = t^2 - x^2 - y^2 - z^2 [1] https://en.wikipedia.org/wiki/Split-octonion https://en.wikipedia.org/wiki/Split-octonion [2] https://en.wikipedia.org/wiki/Minkowski_space https://en.wikipedia.org/wiki/Minkowski_space
