Official Antigravity

 
I have said many times that the government are suppressing science and engineering that produces antigravity, a phenomenon that frees a place or object from the force of gravity within a gravitational field. For examples see the background links below. Therefore I was surprised when I saw the YouTuber "Cool Worlds" upload a video called Artificial Gravity. The channel tends to be very skeptical and has made videos debunking alien life and UFO's. They have even allowed Mick West to deliver his usual nonsense about seagulls and airliners. Artificial gravity means the generation of a gravitational field by non-natural means. Artificial gravity is directly connected to antigravity because it is a hypothetical method for antigravity. Creating an artificial field with an inverted pole of attraction to the natural one would cancel it out. Any object under the influence of both gravitational fields would be in the same state as an object in a zero gravity environment. However, when I watched the video I was disappointed. Actual true antigravity is not even mentioned in this upload. Instead it focuses on pseudogravity. This refers to systems being suggested by spacecraft designers to mimic the effects of gravity through constant acceleration or rotation. In the first example, the spacecraft would be continuously accelerating and the inertia resulting would feel exactly like gravity to anybody inside. This was the system used by the nuclear powered moon rocket in the comic series Hergé's Adventures of Tintin, see: https://blackwells.co.uk/bookshop/product/9781405295901. However, far more popular and practical is rotation. When an object is rotated it produces the centrifugal effect or "G-force". You can easily experience this yourself by sitting on a fairground carrousel. If you build a spacecraft that rotates, or even has a module that rotates, inside that structure the astronauts would experience this simulated gravity effect. There are many designs, such as the giant space colonies proposed by Gerard O'Neil. This would be a huge cylinder in earth orbit that would roll so that people could walk on the inside of it. There is a smaller design by NASA and Stanford University which is shaped like a wheel which works on the same principle. This is the space station depicted in the book and film 2001- a Space Odyssey, see: https://www.youtube.com/watch?v=0ZoSYsNADtY. On such a space station, it would feel relatively normal. You could stay up in space for much longer, not suffering the health problems people get when spending a long time in the microgravity of the existing orbiting space stations.
 
There are problems with rotational pseudogravity though. Constructing the rotating module would be complicated and very expensive. There is an experimental model planned to be attached to the International Space Station at some point, called Nautilus X, but it hasn't been built yet. The rotation would be difficult to control. In fact O'Neil's design would need two cylinders connected and spinning in opposite directions. Each would act as a gyroscopic balance to the other to prevent them both tumbling and wheeling chaotically. There is also an annoying obstacle known as the Coriolis effect. An astronaut in a rotating structure, a centrifuge, would be fine so long as they were sitting still or lying in bed, but once they started moving around all kinds of strange things would begin to happen. For example, in the 2001 film there is a scene where an astronaut is running around the cabin in multiple circuits. If he ran in the direction of the compartment's rotation then he would feel himself getting much heavier. If he reversed direction he would feel himself getting much lighter; in fact if he ran fast enough he may even lose all his weight and find himself floating freely like an astronaut on the ISS does in real life. In the spacecraft in the film, called Discovery, the centrifuge is accessed by a ladder leading down from a separate compartment in the axle. In this axle you would feel completely weightless. As you descended the ladder you would get heavier and heavier as you climbed closer to the rotating rim, the floor of the cabin; but it's not as simple as that. You would also feel another force square to the rotation, as if something were trying to tug you sideways off the ladder. It would take a lot of training to get used to the Coriolis effect and on long space missions it could be very disorienting. Source: https://www.youtube.com/watch?v=b3D7QlMVa5s. It would be far easier and simpler just to declassify true artificial gravity engineering. Spacecraft using it would not need to spin or constantly accelerate. They could look and behave exactly as conventional spacecraft do, except that inside them the astronauts could enjoy a gravitational field exactly like the one they left behind on earth. Yet, there is more. The same means to generate a force that could hold everything down inside the spaceship could also be a method of propulsion, eliminating the need for rockets, with their very limited range; not to mention all their lack of availability, waste, expense and danger. It would revolutionize space exploration... And maybe it already has, in the secret space programme.
