Bush Plans To Nuke Iran! Fooled you all, haha.
Alright, the human body deteriorates in zero-gravity so quickly that within a year a person may suffer physiological damage so bad that he must
live in space the rest of his life...which I'm guessing would be short. Zero-g is a fun place to visit, but not to live. We must live on a planet
which provides healthy gravity levels to promote longevity, or under acceleration while in space.
The Moon's gravity is not sufficient to stop the trend of deterioration, nor is Mars'. Short of some breakthrough in gravitic science, Man is
going to live in space in one of these two scenarios; under thrust to provide perceived gravity, or in a rotating space station or ship which provides
useful centripedal force.
Dang I forgot the link, but an article I just read by that guy that bashes NASA all the time, that ex-space historian guy, says that rotating space
stations that could A) keep it's occupants healthy permanently gravity-wise, and B) able to manufacture all its needs self sufficiently, would take
so many billions it'd be unspeakable to the point of impossibility for us as a race to accomplish in a long, long time. But in space, power is free,
is my point...once you get the infrastructure for power generation set up in space you can use it for umpty years...solar cells have no moving parts,
and do not wear out, do they?
Why are we flirting with the idea of a permanently-manned lunar colony? The crews would have to be rotated back every six months. There's no place
to permanently GO out there, if Mars' gravity is unhealthily weak for the lifetime of a man...unless it's either under thrust the whole way, or in a
rotating spacecraft. Flashback to that movie, uh, what was it's name...
I think the answer's neutronium, that collapsed neutron-star material. That stuff weighs twenty tons a teaspoonful. A foundation slab of that made
under a lunar colony would provide a controllable gravity, depending on the thickness.
Seems to me that the future of Man in space depends on harvesting energy for self-sufficiency, and gaining control over practical gravitics. NASA,
set up a huge solar-powered robot-run factory on the Moon, to make useful materials which don't have to be lofted out of Earth's gravity well. And
push hard to get us some of that condensed neutron-material, I can think of all sorts of uses for that.
NASA's sole and penultimate goal is to put Americans into space, permanently, so they not only survive but prosper, in the proper realization that
at some point in America's future this world will suffer major overcrowding.
Gravitic Drive Idea
In a one-gravity situation you'd be falling at 32m/s2...but you experience zero g while falling.
In a 2g situation you'd be falling twice as fast, but you'd experience zero g. You're falling.
If you were falling into a gravity well of twenty gravities, you'd be accelerating at a hellacious rate. But would you feel fine, and not all
A drive using this concept might incorporate neutron-star material.
I imagine it's pretty hard to work with. How could we harness this aspect of physics to provide accelerations to the human body (which we like to
preserve) at potentially amazing rates? I'm thinking if you could shoot gravity in a beam, that'd be nice...whether it's attraction or repulsion,
you'd still experience zero-g.
Somewhat rambling post, sorry.
