Piggybacking on this question
If you blow up a nuke inside a lead cube thick enough so that it doesn't crack, what happens to all the energy? If I opened the cube years later, would it be explosive?
I tried out some math with this, and assuming the lead is room temperature, the bomb is placed in the center, the lead cube is perfectly cubic, and all energy is released equally into the surrounding lead in the form of heat, in order for any of the energy to escape the lead cube, the nuclear bomb would have to give off at the absolute least 237,654,415,700,000,000 Joules of Energy, or about the equivalent of 56700 Kilotons of TNT. The only nuclear bomb ever created that could even get close to that power would be the Tsar Bomba, which could release around 200,000,000,000,000,000 Joules of energy.
I should clarify, it's not that no energy will escape the cube, it's that there would be no outward indication of damage (no melted/boiled/damaged lead on the outside of the cube.)
As other anons have already said, it would be more than capable of absorbing the energy from a standard nuke, nothing visible would happen to the cube.
The cube would weigh over 11 billion metric tons, for comparison Mt. Everest weighs approx ~170 billion metric tons. If you live in an area where the bedrock is very deep down then you might be in trouble.
It would be very painful
for you
How big is the nuke? fission or fusion bomb?
This. Not sure where you would get a 1km cube of lead to begin with, but that much mass would take a lot of kilotons of TNT to move.
that much mass would sink into the earths crust and just disappear in the magma. we are talking about 11.342.000.000 tons
just attach some balloons to it
What if you put it in orbit instead? Probably easier to work with.
Borg cube
The CIA will come and drink your milk
First off you would probably be arrested
SHALL. NOT. BE. INFRINGED.
A. WELL. REGULATED. MILITIA.
that's a lot of lead my man
>that's a lot of lead my man
How much room in the empty void?
Major fallout.
Cobalt would be much worse.
Cavitation and possibly spallation depending on the megatons. If the bomb was big enough, the cube would blow up.
put your ear against the cube's surface and listen
I don’t know, but let me know when you figure it out - I’ve been looking for a way to deorbit Phobos

Have you taken thermodynamics? It will just heat the lead until there is no more heat to distribute
No more heat flow to distribute *
Corrected it for you.
your lead cube would sink into the earth's mantle.

the lead would absorb all of the energy by plastic deformation
You'd get a lead ball, 1 kilometre thick
