About Euclidean’s space and Vacuum’s space.
Everybody knows what Euclidean’s space is.
Question: what is Vacuum?
“Remember gentlemen, we have not proven
the aether does not exist, we have only proven we do not
need it (for mathematical purposes)”…
/ Einstein’s famous University of Leyden lecture
of May 5, 1920./
" The problem of the exact description of vacuum, in my opinion,
is the basic problem now before physics. Really, if you can’t correctly
describe the vacuum, how it is possible to expect a correct description
of something more complex? "
/ Paul Dirac ./
Herman Minkowski said about his minus 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.”
Question. What is the “a kind of union of the two “?
Nobody knows what really Minkowski space is .
In Wikipedia we can read:
“ Unfortunately neither the concept of space nor of time is well defined,
resulting in a dilemma. If we don’t know the character of time nor of space,
how can we characterize either? “

“Now we know that the vacuum can have all sorts of wonderful effects
over an enormous range of scales, from the microscopic to the cosmic,”
said Peter Milonni
from the Los Alamos National Laboratory in New Mexico.
