![]() At a few meters above, the effect would be much smaller already. Directly on the sheet, the effect would be to cancel gravity. But that is not the case.Īs HiddenHeart mentions, the effect would only be proportional to the part of Earth hidden by the shield. For instance, if gravity comes from the center of gravity. The idea that it affects the air in a column would mean that gravity acts vertically only. It seems you could create free energy out of it. I have heard of that story before, but I never thought of what would "actually" happen. Wikipedia, Google, Mathworld, Integer sequence DB Oh, what the heck do I know can't someone just simulate what'll happen? Of course surrounding air has quite a bit of kinetic energy and would happily dart across the sheet (in nice straight lines since above it it isn't effected by gravity to curve it's path). I would guess air above the sheet would spill down from the 'gravity mountain' to the surrounding gravity sink of the earth. Some people are average, some are just mean. « Last Edit: Jan 21 st, 2008, 1:14am by HiddenHeart » OK, i think i have already talked too much Because it is attracted to the earth by itself and as it cannot create a substantial change in the pressure of the air at its space side so nothing will happen! I guess the sheet itself need not be fastened to anything. Almost(but not exactly) as the same pole of magnet repulses aside when we try to put them in contact.ĥ. He cannot actually stand on that!! I guess when he try his feet will be pulled aside. If the person is not already standing on the sheet. After that he will be pulled aside and eventually pulled down due to the Earths asymmetry & attraction.Ĥ. But he cannot go much higher, i guess just a few meters will be his range. ![]() so due to the centrifugal force he will be thrown up. Now if we don't talk about air particles and have something solid. Which depends mainly on the depth of the particle measured from the outer hemisphere (h g).ģ. The only things that keep it there is the pressure(i boldly use this term) on it from other particles. But it would not be very much because at the Earths surface level each air particle already has a high kinetic motion due to their temperature. A particle just on the sheet might have some problem. The gravitational drug on the particle towards the earth at this point is an integration of the whole earths attraction to it except the portion that is blocked by the sheet which is ignorable.Ģ. ![]() At the out-most sphere the air particles just on the sheet would stay where it is! because the minute fraction of gravitational wave that reaches to it through the sheet doesn't count there. If the sheet is fastened down and unmoving and if any gravitational wave cannot pass through it then these might happen:ġ. When their digits are reversed? " - Anonymous So my question is: If such a material were possible, what really would happen if it were created in a horizontal sheet of a few meters width and length? Assume that the sheet is fastened down and unmoving. While a good story, this doesn't strike me as good science, even by the standards of the late 19th century when Wells wrote it. Fortunately, the resulting maelstrom catches the sheet itself up and hurls it into space, thus narrowly avoiding the complete removal of Earth's atmosphere. The air rushing in also suddenly becomes weightless and is pushed up as well in a great fountain spewing air into space. Wells describes that the air above the sheet suddenly became weightless and is pushed up the pressure of the surrounding air, which then rushes in to fill the void. In the story, cavorite is accidentally first created as a horizontal sheet. In this story, the characters are able to travel into space by means of a newly created alloy called "Cavorite", which is able to block all gravitational attraction. Wells, and finally have the opportunity to read The First Men in the Moon. I recently obtained a collection of several stories by H.G.
