Not possible. Even if you crushed all the mass in the solar system together it couldn't become a black hole.
An underground nuclear blast is referred to as an underground nuclear test. It involves detonating a nuclear weapon below the surface of the Earth, effectively containing the explosion underground. This type of blast generates seismic waves that can be detected and analyzed for various purposes, including testing nuclear weapons technology.
There will be an earth shattering kaboom
Because the Blast and radiation are considered harmful to all lifeforms on the Earth.
Not anything of any size that we're capable of building now or in the foreseeable future. But give us time.And it's "nuclear", not "nucular".
the earth will blast when wedo bad things
Nothing. It cannot happen.
no
They can blow up earth.Think about Herishima.Similar thing will going to happen if the nuclear weapons are usedNo one has built or will build a nuclear weapon or enough nuclear weapons to "blow up the earth", it would have no military value. However the collateral damage in fallout from any major attack would likely kill far more people than the attack itself, and those results are unpredictable.
earth is going to demolish in 3,456,537,289
Well that's a very simple answer.Earth can not become a Black Hole because we live on Earth as you know.
No. A nuclear winter (by its name) is a cold period brought on by dust and debris in the atmosphere blocking out the sun after a nuclear explosion. This lack of sun would cause the earth to cool dramatically depending on the size of the blast. If a nuclear winter occurred we would be heading into another ice age rather than away from it.
Whether lead could protect you from a nuclear blast or not depends on how far from the centre of the blast you are, how thick the lead is and how powerful the blast is. Lead alone would only really protect you from the ionising radiation given off by the blast; provided that the lead is thick enough and that you were far enough away from the blast itself. If you were quite close to the blast then the explosion itself is the biggest danger to you as it is powerful enough to flatten buildings and reaches temperatures of tens of millions of degrees. A hiroshima-sized blast would vapourise almost everything within at least a 1 mile radius and would make short work of lead (which has a boiling point of only 1749 degrees.) Lead is only used to shield from ionising radiation because it is very dense and so a thinner layer of it can absorb the same amount of radiation as a much thicker layer of a less dense material. This means that, while lead alone would not make much difference close to the blast, if you were further away (preferably in a bunker) then the lead (if thick enough) would be useful to absorb most of the ionising radiation given off by the blast A better solution for protection from radiation and the blast is earth and rock. However more radiation is absorbed by smaller thicknesses of denser materials so you would need much more material between you and the blast then if you used lead. However the larger thickness of material may protect you from the blast and thermal radiation effects.
