Who has the biggest nuclear bomb in the world?
The Soviet Union also tested the most powerful explosive ever detonated by humans, (“Tsar Bomba”), with a theoretical yield of 100 megatons, intentionally reduced to 50 when detonated. After its dissolution in 1991, the Soviet weapons entered officially into the possession of the Russian Federation.

What makes nuclear bombs so powerful?
This is known as a chain reaction and is what causes an atomic explosion. When a uranium-235 atom absorbs a neutron and fissions into two new atoms, it releases three new neutrons and some binding energy. Two neutrons do not continue the reaction because they are lost or absorbed by a uranium-238 atom.
How many H Bombs does the US have?
The U.S. and Russia possess comparable numbers of nuclear warheads; together, these two nations possess more than 90% of the world’s nuclear warheads. As of 2017, the U.S. has an inventory of 6,800 nuclear warheads; of these, 2,800 are retired and awaiting dismantlement and 4,018 are part of the U.S. stockpile.

How did Pakistan get nukes?
Pakistan conducted peaceful nuclear research from the time of its independence but began a nuclear weapons program in earnest only after its defeat by India in 1971. Pakistan’s nuclear weapons program began in 1972 under Prime Minister Zulfikar Ali Bhutto, who had always been a proponent of going nuclear.
How many nuclear bombs have been detonated?

What is the blast radius of a nuke?
Death is highly likely and radiation poisoning is almost certain if one is caught in the open with no terrain or building masking effects within a radius of 0–3 km from a 1 megaton airburst, and the 50% chance of death from the blast extends out to ~8 km from the same 1 megaton atmospheric explosion.
Does Canada have nukes?
Canada has not officially maintained and possessed weapons of mass destruction since 1984 and, as of 1998, has signed treaties repudiating possession of them. Canada ratified the Geneva Protocol in 1930 and the Nuclear Non-proliferation Treaty in 1970, but still sanctions contributions to American military programs.

According to Linus Pauling, Einstein later regretted signing the letter because it led to the development and use of the atomic bomb in combat, adding that Einstein had justified his decision because of the greater danger that Nazi Germany would develop the bomb first.
Can antimatter be used as a weapon?
An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon. Annihilation requires and converts exactly equal masses of antimatter and matter by the collision which releases the entire mass-energy of both, which for 1 gram is ~1.8×1014 joules.
Does Japan have nuclear weapons?
Since the bombing of Hiroshima and Nagasaki, Japan has been a staunch upholder of antinuclear sentiments.
