Interesting. Forgive my falling back on things I'm familiar with ... but doesn't the idea of "matter arising from 5D geometry" remind you somewhat of how sinusoidal motion on the "real" axis, is a reflection of circular motion in the complex plane?

Perhaps there's even a connection -- maybe that 5th dimension has some correspondence to an "imaginary" time axis, as opposed to the "real" time we experience.

Thank you so much for your excellent post, r9etb!

Indeed. For Lurkers: Comparing Circular and Sinusoidal Motion

Perhaps there's even a connection -- maybe that 5th dimension has some correspondence to an "imaginary" time axis, as opposed to the "real" time we experience.

That appears to be the focus of this article from the same group:

betty boop, you might be interested in the above article also.
