1. I'm just wondering if time and space are realy two aspects of the same
thing, prhaps on the string level, each can be partially deformed, more or
less, into the other? Since they're basically the same generically. So there
might be some kind of meaning in talking about at least three dimensions of
time,i.e. 1-D might be duration, 2-D might be wider duration, 3-D might be
deeper duration.
If time and space are somehow convertible, that might explain some
anomalies, such as modern coins being found in carboniferous strata, etc

2. String theory apparently assumes there are 10 or maybe 11 spatial
dimensions, and 1 temporal dimension. It also seems toassume that gravity is
the same force through all dimensions. Since these dimensions are originally
are curled up, I am going to assume that every object exhibits at least one
higher, and maybe every higher, and maybe lower dimension.

If a straight line deformed into a circle, a 1-d observer would see less
of it. The line would appear to shrink. If the line was massive enough, the
pull of gravity would be deflected from the observer. If a circle deformed
into a sphere, the circle would also appear to shrink to a 2-D observer, and
the horizontal gravitatational pull would decrease as a vertical pull
manifested itself, if the sphere was quite a bit larger than the observer.
The 2-D guy would feel a strange tug 'upward,' which would be eerie. If a
sphere deformed into a hypersphere, the sphere would appear to shink. The
hypersphere would not necessarily enclose the observer; it might still be in
front of him, I guess. If it was massive enough, and large enough, he would
feel a strange tug, but I can't even imagine it. By analogy, the forces of
horizontal and upward gravitational pull would lessen. and a new kind of
pull would increase, which would be eerie too.

If time and space are two aspects of the same thing, then thinking just in
terms of higher spatial dimensions might be misleading.

3. I am wondering if sound can unite or penetrate all the dimensions?
Could a 4-D person talk to a 3-D person without being seen? I am not sure if
electromagnetic waves would. Sound just induces a resonance. But apparently
gravity can penetrate all the dimensions too, so I wonder if there is any
connection between gravity and sympathetic resonance? They seem totally
different. OM! (Nothing happened.)

4. Finally, and irrelevantly, in Brian Greene's book The Elegant Universe
(Cloth, 1999), p. 197, Einsteain developed a more congenial attitude toward
Kaluza's idea of a 4th dimensional space that unfied gravitation and
electricity. Did the alleged 'Philadelphia Experiement,' on which Einstein
and Tesla are supposed to have worked, occur in that time frame? Apparently,
the idea was to use powerful rotating magnetic fields to produce
invisibility; maybe this has something to do with photons carrying
electromagnetic charge, and producing cancellations in the photon fields.
But apparently time and space went crazy.. Oh well. Stuff happens.
