eventually pinning you to the walls). Once you've found one, you need a helium balloon. Any size will do. The last thing you need is a wad of chewing gum. Now this bit can be a tad fiddly, but you need to attach just enough chewing gum to the string (tied to the balloon) so that the helium balloon neither sinks to the ground, nor floats away into the atmosphere. It doesn't have to be perfect, though. It CAN sink/ float a little, as long as the rate of climb/ fall is very small, as you'll need to observe it in the next part. The Next Part: - Take your helium balloon avec gum into the gravitron ride and before the ride starts spinning, release your balloon into the middle of the room. It doesn't have to be the exact middle of the room, really, just as long as it's somewhere where the balloon will not be struck by any part of the rotating room. Observe the results. Outcome: - The spinning room fails to generate or even simulate any kind of gravitational effect on the oblivious balloon. You'll see that it doesn't matter how fast or how slow the room is spinning, the balloon will continue to float in the middle of the room, oblivious. It's remotely possible that the moving air generated by the spinning room might cause the balloon to move, but that's NOT artificial gravity through rotation. That's just wind affecting a balloon! Conclusion: - You can't expect things that work in an environment where the pull of gravity is 'countered' by the person/ the earth to work in an environment where there is no equal/ opposite reaction to gravity, ie: Microgravity or 'Zero' gravity. The balloon remains unaffected by the spinning room because there are no forces acting directly upon it. However, you can change this. On the Artificial Gravity page itself, the 2nd figure there, the moving gif one? If we assume that this is a top-down image of a rotating section of a space craft in microgravity, then once again, an astronaut floating in that room will continue to float in that room, regardless of how fast or how slow the room spins around him. He will never be pushed outwards to the rim, because there are no forces acting upon him (in that direction, or otherwise). HOWEVER, if you extend the 'spokes' in that image all the way from the hub to the rim, an astronaut floating anywhere inside will now find that once the station/ section starts rotating, while he is floating he will soon be struck by these 'spokes' and they will directly apply force to him in the direction of their travel. Of course, because the inside of a circle has a smaller circumference than the outside, these 'spokes' should be angeled to offset this (It's been many years since I did the calculations for this, but if memory serves, the optimal angle is about 13 degrees above the zero degree plane of a radian). Thus these spokes will serve as the floor, NOT the rim. Never the rim. If you find any of this confusing, just do the experiment for yourself. Once you're inside that spinning room, watching the balloon continuing to remain to be unaffected by the rotation, it should all make sense. Peace Raz
1590:(with, for instance, two spacecraft tethered together by long cables and rotating around each other, as in the 1989/90 Mars proposal) to research how the human body reacts to long periods of artificial Earth-strength gravity (and to learn about the optimum cable length, as too long is heavy and expensive, etc, and too short causes dizziness problems, etc, and what is the optimum number of cables to compensate for cable-snapping or micrometeorite-cable-cutting risks, etc) as seemingly needed for manned flights to Mars and beyond, as well as to long periods of lunar and Martian gravity as needed for prolonged work on the Moon and Mars (presumably interspersed with recuperation periods in artificial Earth-strength gravity in spacecraft or space stations orbiting the Moon or Mars). The cable-snapping or micrometeorite-cable-cutting risks would presumably be higher in a space station near Earth than in interplanetary space due Earth attracting them, and due artificial space debris orbiting Earth, etc. Do any reliable sources say any of this? 1271:
than the size of the hidden dimensions, can enter them. Producing ultra-short photons can thus manipulate gravity, with revolutionizing space travel applications such as cheap anti-gravity launches. The problem that it would require high energy can be practically solved by concentrating several laser beams on a nanoparticle, heating it to locally extreme temperatures. An Alcubierre metric can be created by ejecting multiple nanoparticles from the craft and then beam perfectly timed laser beams on them (fire at the most distant first so that they are hit simultaneously), so each nanoparticle contributes a slower than light effect but together add up to faster than light, creating no discrete event horizon and thus no Hawking radiation.
200: 2440:, a simpler and easier way to generate artificial gravity. Using circulating air, one can create constant force on the body. This doesn't create a constant and uniform force like gravity, as it just affects the surfaces, but being in a constant force will mimic/simulate gravity and mitigate health effects like bone and muscle loss. Further, it can also be used on planetary surfaces to increase the gravity to earth's. It's simple to implement and the technology already exists. It is not constrained by size like centripetal force idea and others. 2281:
this little keener is from where there are alternative mechanisms for artificial gravity which come within an observable universe's distance of being as tractable as rotation for generating gravity. Maybe this fine person would like to speak up and explain why they felt sufficiently well informed to make this comment. And no, I am by no means the person who wrote the original sentence, just a human with a working brain and a passable knowledge of physics (got a piece of paper somewhere that'll back that up).

The hypothetical "Discovery" spacecraft in "2001: A Space Odyssey" appears to represent an example of such a design. (Whereas the Russian spacecraft "Leonov" depicted in "2010: The Year We Make Contact" appears to require a pressure seal between the sections.)

I would tend to agree with you. I just removed an even more off-topic blob of prose. Have left a hidden note in that meta-subsection inviting other editors to consider whether neutral buoyancy and parabolic flight should be similarly removed. It seems off topic; but I think we need a 2021 look by
