Ranting about: The end of the world

No not the song

Anyone else is getting annoy with this.

1. Telling everyone = Panic = no fun.

2. No Proof.

Yes the calendar will end but is their really infinite calendars.

3. Everyday is the end.

The world end today no tomorrow no a week no a month no a year. Wrong! The world will end when the sun dies and that's a very long wait.

4. End

Why is it the end of the world its the end of life on planet earth.

Again

This Month

Black hole

Ok but we are still alive the last time.

A nuclear weapon is an explosive device that derives its destructive force from the nuclear reaction of fission or from a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter; a modern thermonuclear weapon weighing little more than a ton can produce an explosion comparable to the detonation of more than a billion kilograms of conventional high explosive. Even small nuclear devices with yields equivalent to only a few thousand tons of TNT can devastate a city. Nuclear weapons are considered weapons of mass destruction.

In the history of warfare, only two nuclear weapons have been detonated offensively, both by the United States of America during the closing days of World War II. The first was detonated on the morning of 6 August 1945, when the United States dropped a (uranium) gun-type device code-named "Little Boy" on the Japanese city of Hiroshima. The second was detonated three days later when the United States dropped a plutonium implosion-type device code-named "Fat Man" on the city of Nagasaki. These bombings resulted in the immediate deaths of around 120,000 people from injuries sustained from the explosion and acute radiation sickness, and even more deaths over time from long-term effects of (ionizing) radiation. The use of these weapons was and remains controversial. (See Atomic bombings of Hiroshima and Nagasaki for a full discussion.)

Since the Hiroshima and Nagasaki bombings, nuclear weapons have been detonated on over two thousand occasions for testing purposes and demonstration purposes. The only countries known to have detonated nuclear weapons - and that acknowledge possessing such weapons - are (chronologically) the United States, the Soviet Union (succeeded as a nuclear power by Russia), the United Kingdom, France, the People's Republic of China, India, Pakistan, and North Korea. Israel is also widely believed to possess nuclear weapons, though it does not acknowledge having them. For more information on these states' nuclear programs, as well as other states that formerly possessed nuclear weapons or are suspected of seeking nuclear weapons, see List of states with nuclear weapons.

Apart from their use as weapons, nuclear explosives have been tested and used for various non-military uses. Synthetic elements, such as einsteinium and fermium, created by neutron bombardment of uranium and plutonium during thermonuclear explosions, were discovered in the aftermath of the first thermonuclear bomb test.
