Re: The Double Universe.

The Double Universe. More details.
e)
Herman Minkowski said about ( -4D ) spacetime continuum:
“ Henceforth, space by itself, and time by itself,
are doomed to fade away into mere shadows,
and only a kind of union of the two will
preserve an independent reality.”

It means that the Universe as whole is Two - Measured World.
One world is Minkowski union of spacetime continuum.
Another world is shadow of it because the time and space
are different conceptions.
