[edit] The Halo in the Halo series of videogames

Somebody should add the halo's in the videogames Halo and Halo 2. I'm too tired as of the now. :\

[edit] Field generator is not not only fiction anymore

someone should add the recent discovery made at the ESA (see www.esa.int/SPECIALS/GSP/SEM0L6OVGJE_0.html ). I'm not qualified enough to do so, so someone else should probably do. >_>

[edit] fomulae for rotation

Can someone add formulae regarding the numbers that are in the rotation section? The numbers that I get by using the formulae at centrifugal force give me a smaller necessary radius. Rusco 14:09, 25 July 2006 (UTC)

I just checked it; 224m at 2rpm that means:

r=224 w=0.209 radians per second

rw^2 = 9.826 m/s^2 WolfKeeper 20:54, 25 July 2006 (UTC)


THERE IS NO SUCH THING AS CENTRIFUGAL FORCE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

There is centrifugal force in a rotating reference frame, as well as coriolis force.WolfKeeper 02:45, 9 August 2006 (UTC)

There is also Centrifugal force in a stationary reference frame in ideal circular motion. However instead of the object having centrifugal force exerted on it, it would be exerting centrifugal force on the circe. I.e on a merry-go-round or somesuch. —Preceding unsigned comment added by 134.226.1.234 (talk) 12:40, 17 September 2007 (UTC)

[edit] Simulations

If anyone is interested, I wrote a Java applet to simulate rotational gravity in a space station.

I think it's kinda fun, YMMV.WolfKeeper 04:23, 17 October 2006 (UTC)

[edit] lol rly funni quote whoever edited this

"The Mars Gravity Biosatellite will study the effect of artificial gravity on mammals. An artificial gravity field of 0.38g (Mars gravity) will be produced by rotation (34 rpm, radius of ca. 30 cm). Fifteen mice will orbit Earth for five weeks and land alive. Just kidding..."

lolol 30 cm radius thats pretty cramp living quarter for 15 mice

lolol 34 rpm so fast, mice will be back on earth ALIVE after 5 weeks?

if those are true those ppl should b arrested for animal abuse! jk

-Will Suh-

Animal's can't be abused. They aren't people and have no rights.

[edit] Magnetic boots

Hey, there is no mention of magnetic boots! There's a redirect page "Magnetic boots" to Artificial gravity, but it's not mentioned... SuperMidget 16:34, 8 July 2007 (UTC)

[edit] x in the formula indicates crossproduct?

If I understand this formula properly, this \times is used as a multiplication sign. Does someone know why the usual sign \cdot isn't used?


g = \frac{R(\frac{\pi \times rpm}{30})^2}{9.81}
Where:
g = Decimal fraction of Earth gravity
R = Radius from center of rotation in meters
π = 3.14159
rpm = revolutions per minute

The dot isn't usual in my experience. Usually, multiplication is represented by simply juxtaposition. For example e = mc2, where the m and the c2 are multiplied with no explicit operator. In my experience, when an operator is used for multiplying numbers, it is more often the cross than the dot, and in this case we need an operator or else rpm will look like three variables being multiplied together. A better solution might be to reduce rpm to a single letter, then use juxtaposition. -- Lilwik 19:30, 11 July 2007 (UTC)

[edit] Broken Link

The link to "http://users.wpi.edu/~rcaron/mars/gravity.shtml" brings up a 404 error. If anyone can update the link, please do so. —Preceding unsigned comment added by Tuki (talk • contribs) 19:14, 6 November 2007 (UTC)


[edit] Corkscrew Pattern

What about this - a spaceship moving in a spiral or corkscrew pattern, whith a constatnt velocity along the axis of the corkscrew and the proper diameter and velocity around the circumference of the corkscrew, would move through space at whatever speed desired and provide constant gravity. Essentially you would need to provide thrust of 1g with a vector directly into the center of the corkscrew and then rotate the ship so that "up" is always facing the center. How about it?

No known propulsion system can work for long enough to make this worthwhile; it uses either obscene amounts of propellant, and/or obscene amounts of energy.WolfKeeper 23:21, 6 November 2007 (UTC)
