From a daily new bulletin I receive:
"Superstring theory (sometimes just called string theory) has as its
basic premise the belief that the four fundamental forces of nature
(gravity, electromagnetism, and strong and weak nuclear forces),
as well as all matter are simply different manifestations of a single
essence. This essence, the material making up all energy and matter,
is thought to consist of tiny (a hundred billion billion times smaller
than the nucleus of an atom) vibrating strings that exist in a multi-
dimensional (10 or 26 dimensions) hyperspace. The extra dimensions
(beyond the ones we recognize: three spatial dimensions and time) are
thought to be
compactified, or curled up, into
tiny pockets inside observable space. The particular vibrations of the
strings within this multidimensional hyperspace are thought to
correspond to particles that form the basis of everything - all matter
and energy - in existence."
What, may I ask, is wrong with "compressed" or even "compacted"?
