Anti gravity

1. Anti-gravity

2. Anti-gravity : Anti-gravity is an idea of creating a place or object that is free from the force of gravity. It does not refer to the lack of weight under gravity experienced in free fall or orbit, or to balancing the force of gravity with some other force, such as electromagnetism or aerodynamic lift. Anti-gravity is a recurring concept in science fiction, particularly in the context of spacecraft propulsion.

3. Like most people, you probably took gravity for granted before space flights began . You know Earth's normal gravitational pull holds you to the seat of your chair-and more importantly keeps you from being tossed into the air by the Earth's rotation.   But gravity causes a lot of trouble and expense we seldom think about. Aircraft and rocket builders have to provide heavy engines and huge weights of fuel, just to offset gravity. In construction of buildings, bridges and in a hundred other ways g ravity affects our lives and adds billions to the cost of work. Gravity control could reduce or end many of these problems. Why we need anti gravity:

4. Global Warming obviously now affecting us, in the next 20 or 30 years or so when our planet will be too hot to live in, we could use anti gravity technology and anti gravity propulsion to explore space much more adequately and find suitable planets to migrate. Continue:

5. Newton's theory of general relativity: In Newton's law of universal gravitation, gravity was an external force transmitted by unknown means. In the 20th century, Newton's model was replaced by general relativity where gravity is not a force but the result of the geometry of space-time. Under general relativity, anti-gravity is impossible except under contrived circumstances.

6. How to produce anti-gravity: One easiest way to produce anti-gravity is described by sir Hermann Bond using negative mass. Sir Hermann Bond proposed in 1957 that negative gravitational mass, combined with negative inertial mass, would comply with the strong equivalence principle of general relativity theory.

7. Sir Hermann Bond pointed out that a negative mass will fall toward (and not away from) the matter, since although the gravitational force is repulsive, on the other hand, normal mass will fall away from the matter. The negative mass (according to Newton's law, F=ma) responds by accelerating in the opposite of the direction of the force. He noted that two identical masses, one positive and one negative, placed near each other will therefore self-accelerate in the direction of the line between them, then the negative mass chasing after the positive mass. So negative mass will show the anti-gravity effect.

8. In theoretical physics, negative mass is a hypothetical concept of matter whose mass is of opposite sign to the mass of normal matter, e.g. −2 kg. Such matter would violate one or more energy conditions and show some strange properties. Negative mass:

9. Anti-gravity devices: Anti-gravity devices produce a force when twisted that operates "out of plane" and can appear to lift themselves against gravity. A device is shown invented by Henry Wallace. His device is consists of super conducting ceramic ring and solenoids. He claimed that by passing current through solenoid results in creating a "gravitomagnetic" field which shows anti gravity effect.

10. NASA researchers hope to conduct an experiment that could determine if the force of gravity might someday be adjusted, like the volume of a radio. "In 1992, Dr. Eugene published the results of his experiment with high-temperature ceramic superconductors,” "He devised an experiment in which a disc of superconducting material was magnetically levitated and rotated at high speed, up to several thousand rpm, in the presence of an external magnetic field. NASA a ntigravity m achine :
