The Force of a Nuclear Weapon
The initial primary destructive force of a nuclear weapon takes place in a
milliseconds. In under a second an area with a radius of twenty or more miles can be completed devastated. People and plants alike are erased completely when they are close enough to the epicenter. Entire city blocks instantaneously turned to plasma and what it is not turned to plasma is obliterated and irradiated. A nuclear weapon crashes down on a location bringing Earth's greatest destructive forces with it. Not only is the location assaulted by immense heat, radiation, atmospheric pressure change, seismic shock, and sonic oscillations but up to decades even centuries later the weapon leaves its mark ; an impact crater and fallout. The amount of power is so massive it is measured in megatons of yield; megatons of dynamite.
The first effect of a weapon is an extremely powerful force that is released instaneously as the weapon detonates. The quickest traveling form of energy known to man, being light, is released in the form of photons and neutronic radiation. About eighty percent of the light seen from a distance is photons that have been released in tightly packed bundles. For this reason they can blind a person up to ten miles away from the outer most destructive forces of the bomb. More specifically the tight group of photons makes up a form of light that is what's referred to as a perfect energy. Unstoppable until different factors cause the group to start dispersing and taking separate paths of flight. It is this perfect energy that destroys everything in its path by destroying the bonds between the atoms that make it up. The slower neutronic radiation is a form of energy created from neutrons being forced from the nuclei and propelled at great speeds. These two energies combined literally tear apart atomic bonds and are unstoppable until they loose their cohesion. The light that at the epicenter usually is about a quadrillion times brighter than the sun per surface area unit.
The heat produced by matter being exposed to such high level of such powerful energy produces temperatures which are sixty to one hundred million degrees centigrade. This is about ten thousand times the surface temperature of the sun. Matter exposed to these temperatures is turned to plasma in a matter of one to three milliseconds. The heat also causes what is known as a flash incineration of all gases within a certain radius depending on the yield of the weapon.
About ten milliseconds after detonation is when the largest group of destructive forces are released. The flash incineration take place in a sphere that extends with the weapon's detonation point being at the center, the size of the sphere depends on the yield of the weapon. The air underneath the sphere is denser so when after the flash incineration occurs the air underneath rushes in first to replace the incinerated air. This rush of air creates an updraft which pulls everything...
