An answer to artificial gravity?
Ever heard of the Stanford Torus? Or the popular Halo game series of that ring shape world. Now lets look into physics. I know, its totally absurd or not in our technology to construct a super structure like that of the novel “RingWorld” by Larry Niven. But i’m not saying its impossible. For something “less” gigantic,lets look at the Stanford Torus. Supposedly driven round creating artificial gravity centripetal acceleration seems rather convincing that between 0.9g and 1.0g of gravity is produced. But what happens if you were to be standing on this ringworld and when its spinning you walk around it. Its no doubt he feels gravitational effect.
1) What if, he were to throw a ball up in the air? Not only throwing up but there’s wind blowing the ball forcing it backwards. The problem is that i don’t see how this ball is ever gonna come down and that gravity only functions when you are in contact with the spinning craft or object.
2) Now what if, you were to stand still on the spinning ringworld. and facing the opposite direction of the spinning ring, you throw the ball almost or about the speed of how fast the ring rotates; in the opposite direction. The ball will be floating in thin air until it comes in contact with the ringworld.
Why is that so? The “gravity” made my the ringworld is just an artifact of a rotating frame of reference. Hence, there is no force acting on anything, imagine you were to look out to the window of the spinning ringworld and not looking out. Anyway since there is no force acting, the ball will move in a straight line as the ground moves in a circular arc toward the ball so it will appear that the ball is falling but actually only staying at its rest position until it hits the ground. Even so if there were to be air in the ringworld enclosed in a dome, i doubt air would be “rotating” just like the craft.
In a nutshell, to conclude that centrifugal as a potential answer to artificial gravity. The answer is, Yes you can. But you cant simulate perfect gravity cause its not gonna be constant. XD

Hi,
We may not have to wait much longer for the answer to whether or not we can “Tame Gravity”.
In fact we may have had the unofficial-official brake through back in 1999.
If your really interested in where our planet is on “Taming Gravity” you might want to read this Popular Mechanics Oct 1999 issue on Dr. Ning Li and her “A/C Gravity”.
The article is titled “Taming Gravity” appropriately.
The article does a very good job of explaining her A/C Gravity. It is a must read for anyone interested in where our planet is on the subject of “Taming Gravity”!
It would be a shame not to include it in our discussions of “howstuffworks”!
