Does Betsey Johnson Make Diaper Bags
scented balls away and moved Antigravity
Flying Saucer One of the handiest items in the science fiction literature is called antigravity. Its effects vary from one author to another, for some isolates the field of gravitational effects as cavorita of Wells, for others it exerts a repulsive force like the force of gravity, which is what allows flying saucers stand on our heads as we abduct for complicated rectal exams.
But antigravity has trancendido thresholds
science fiction become one of the areas of interest for physics. To understand the antigravity must resort to a completely intituitivo mass is negative. If the mass that we know generates, according to current theories of gravity, the warping of space-time surrounding that produces the gravitational attraction between the various objects, produce negative mass repulsion effect on the surrounding objects of equal magnitude to that exerted by gravity. This negative mass is theorized as is given to call antimatter. Antimatter is just like the matter unless he has the electric charge of equal strength but opposite sign to the electron positron exists for the neutron there antineutron for the proton and antiproton exists. All these particles have been discovered and produced in particle accelerators like CERN, but so far not been able to verify whether or not there are particles of antimatter. Experiments have been conducted on a small scale as those by Bill Fairbank, Stanford, that failed due to the inability to build enough straight pipe to be able to isolate them from external magnetic fields.
Experiment Eugene Podkletnov
Antigravity
is also closely related to the high temperature superconductors. Superconductors are materials that are capable of carrying electrical currents with a minimum loss of energy. It all started at the University of Tampere in Finland, where Eugene Podkletnov was working with some ceramic disks by rotating them quickly. During one of his tests found if you put a body on one of these pieces of pottery, and while spinning, weight decreased by 2 percent. After controlling for all conditions which may interfere with the experiment, returned to repeat with identical results. A year earlier had already made some discoveries in this field, when two scientists from Tohoku University in Japan found that a gyroscope spinning at speeds high enough, its weight decreased to 0.001. All this evidence were taken with suspicion within the scientific community, but over time these have been gaining strength, until the point that Eugene has joined a team from NASA to develop rockets antigravity. In addition, all suggests the creation of medium-term gravitational shields.
