Yes, If it was carried into the ozone layer by a space ship and then detonated, then we would be in trouble. :D
The power of a nuclear bomb is a very tiny fraction of the power of the sun.
Build a missile for launching satellites into orbit. Build a nuclear bomb. Replace the satellite payload of your missile with that nuclear bomb. Adjust the missile guidance system to drop the bomb on a selected target instead of injecting it into orbit. Simple?
It is possible to test a nuclear weapon in space, but it is banned. Nuclear weapons have been exploded in space. In 1962 starfish prime test exploded a 1.4 megaton bomb (~100 times bigger than the Hiroshima bomb) was detonated 400 km over the central pacific. The electromagmetic pulse (called an EMP) damaged communications and electronics from Hawaii to New Zealand (a distance of 7000 km). If this was done today it would cause billions of dollars in damages by wiping out computer systems and satellites over an area of millions of square kilometers. The gamma energy of a nuclear weapon is normally turned into heat when exploded in the atmosphere but in space there is no atmosphere to heat up so all the gamma energy is turned into an EMP that fries electronics. Just one bomb exploded over the United states at 500 km would destroy all computers and electronics that were turned on at the time in the entire country. Military electronics are hardened against this.
Human activities can have significant negative impacts on the atmosphere, such as air pollution and greenhouse gas emissions that contribute to climate change. While humans have the ability to degrade the quality of the atmosphere, it is unlikely that we can completely destroy it. However, it is essential to take action to mitigate harmful effects to ensure a sustainable future.
The treaty that stopped nuclear testing in the atmosphere was the Partial Nuclear Test Ban Treaty, signed in 1963 by the United States, the Soviet Union, and the United Kingdom. This treaty prohibited nuclear testing in the atmosphere, underwater, and in space, helping to reduce the environmental and health risks associated with nuclear weapons testing.
No.
no
Theoretically, yes. Practically, no, nobody has ever built a single bomb of high enough yield to destroy an entire country in one shot; also any such bomb would waste most of its yield in simply blowing off the top of the atmosphere into space. It just isn't practical with a single bomb.
A neclear bomb could completly destroy a building :)
yes he has a nuclear bomb which is the most powerful bomb in the world and can destroy the whole of England. apparently there is only 1 in the world now
No!
There are currently no nuclear weapons big enough that just one could destroy the US. It is possible that enough of them could pretty much destroy our way of life for decades to come.
Nobody has a bomb big enough to destroy the earth. The problem is, if one person detonates a nuke, there will be retaliation by other countries. This will lead to nuclear war, and ultimately the extinction of the human race and most other species of animals.
The size of the area destroyed by a nuclear bomb depends on its yield. A small nuclear bomb with a yield of 1 kiloton could destroy buildings within a few city blocks, while a larger bomb with a yield of 1 megaton could impact several square miles. The damage would also vary based on the bomb's design, height of detonation, and local geography.
If you want to destroy a city and kill thousands of people, it is the quickest way of doing so.
To destroy large areas of land. Is one answer. The other is to blackmail other countries into submitting to you.
That would depend on yield and height/depth of burst.
