Is there any scientific invention on antigravity space craft?

Question

i already heard about elctro magnatic vehicle like ufo. computer within 5 years has been so much advanced. but

nasa using same rocket 50 years. is science stoped?

Answer 1

maybe not stopped but reversed? i heard the improvements had exceeded the capabilities,...

Answer 2

The short answer is no. NASA is not actively working on an anti-gravity spaceship. However, there is a lot of interest in space elevators, a sort of tube that hangs from a satellite to earth. People and cargo would then ride inside this tube into space then. Theory suggests that this is viable technology as soon as we can develop the lightweight but strong materials to make up the "elevator". Carbon nanotubes are being seriously looked at for this technology. Stay tuned.

Answer 3

No, that's not possible now or ever, unless you fill the tanks with Dark Energy.

Answer 4

Study very hard and U may be able to teach NASA..

Answer 5

There are a couple of uncredentialed quacks who claim they have demonstrated anti-gravity.  Of course, one of the main ones says his proof was stolen by the government.  Go figure.

I doubt that there is any legitimate scientific work being done on anti-gravity.  The people who would be doing something like that  already realize how utterly unavoidable gravity is.

Answer 6

I always thought the Orion nuclear propulsion was a fantastic idea, but it got shot down by politics

Answer 7

There's a theory called Heim theory that has a countergravitational force. However, Heim published outside of the scientific community and most of his work hasn't been submitted to peer review, and therefore hasn't been verified for accuracy in his observations, measurements, and calculations -- let alone verified in any laboratories.

Despite that, some have used the preliminary translations of Heim's work to investigate the possibility of the antigravitational effect by spinning special electromagnets at high speeds. They found that if the effect does exist that it must be several orders of magnitude smaller than they were able to deduce Heim's theory predicts.

On top of that, another group of researchers hypothesizes that Heim's antigravity breaks symmetry; i.e. the effect would be different depending on whether you spun the device clockewise or counterclockwise. Still no positve results however.

In short: Heim is probably wrong, no matter how interesting his ideas are. His calculus (called selector calculus) is very difficult to comprehend because he uses archaic syntax, some of which he invented in isolation from the rest of the mathematical community.

I wouldn't hold my breath, basically.

Answer 8

Ion drives have been working for nearly 50 years, and concepts go back to 1929.  Of late, you hear that they provide the thrust force of about the weight of a piece of paper.  But a prototype that could hover was demonstrated in 1959.  The reason that they're good is that they provide good specific impulse.  That is, for a given amount of reaction mass, they are efficient at producing thrust.  But you need to provide the energy, which in the demo, was provided over the tether.

There is no known field that can negate gravity.  However, Dark Energy seems to be able to stretch the fabric of space itself, with a sort of anti-gravity effect. Don't expect any sort of usable anti-gravity effect from this little understood phenomenon any time soon, if ever.

However, there is a wizard in Nepal that is working on gravity resistant trees.

Answer 9

No, and it's safe to say there never will be.  An anti-gravity device would allow us to build a perpetual motion machine, and that violates the basic laws of thermodynamics - you can't get something for nothing.
