Ideas without referent or substance: indeed, you could say
that of any particle, so that's pointless, in fact rather
missing the point of *a* geometry, not any.

That said, I do strongly "sympathise" with the it's all fields
approach, but 1) unless we include the boundary at infinity,
it's just broken, and 2) does it really and fully work?  And
I haven't yet found a clear answer to that last one: but, if
the problem is just "time", that's the bit we have now solved.

Sometimes I think I am talking to a rubber wall.
