Nucular WarNuclear Weapons are explosive devices made to release nuclear energy. The first atomic bomb, which was tested on July 16, 1945, at Alamogordo, New Mexico, represented a completely new type of artificial explosive. All explosives get their power from the rapid burning or decomposition of some ...

Black Holesare objects so dense that not even light can escape their gravity, and since nothing can travel faster than light, nothing can escape from inside a black hole . Loosely speaking, a black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to ...

Fission Or FusionI think that right now, fission is the only way that we can get more
energy out of a nuclear reaction than we put in. First, the energy per fission
is very large. In practical units, the fission of 1 kg (2.2 lb) of uranium-235
releases 18.7 million kilowatt-hours as heat. Second, the fission ...

The Prospect Of Cold FusionIn March of 1989, Drs. Martin Fleischmann and Stanley Pons first announced that they had discovered a way of producing heat from metals supersaturated with heavy water. Thus at the University of Utah, cold fusion was discovered. In the weeks following this announcement many other scientists tried ...

Nuclear FusionFor a fusion reaction to take place, the nuclei, which are positively charged,
must have enough kinetic energy to overcome their electrostatic force of
repulsion. This can occur either when one nucleus is accelerated to high
energies by an accelerating device, or when the energies of both nuclei ...
