    Undestructable

    Couple of my friends were talking about motorcycles and a random though hit me...

    What if yuo made a sphere of undestructable material..i dont know what material that is or if it exists...and you put an explosive with a timer in it(plutionium or whatever) and it explodes and has no chance of escaping the sphere...now i know the mass doesnt change when something goes from liquid to gas or whatever. But what if the mass does change(yet again i dont know if there are elements when comibed create a new one and change the overall mass but i think there is because i remember science class and there was something about that i think. So If the mass changes so much that it can't fit inside the sphere but also has no chance of penetrating the walls to get outside, what would happen ?

    I was using gas for example...let's say it's water or metal or something....

    in physics, if an unstoppable force [the explosion] meets an immovable object [your containment] then total annhilation is the answer ...........

    You might like to read up a bit on "black holes", they are the compression of matter to the extreme.

    AFAIK nothing can escape from a black hole, not even light..............that sounds a bit like your sphere?

    Ack pht Nihil you're too fast on the keys

    If you jam enough mass in a small enough space you'll up the density to a point where you'll make a black hole. Every explosion has a corresponding implosion at it's centre, thats how nuclear bombs are set off. So you could sqeeze your mass down pretty small (see someones previous post regarding 4th gen nukes, laser compression etc).
    Unless you are using solar system sized amounts of mass the black hole would be increadibly tiny, probably much smaller than an electron. It could evaporate via Hawking radiation very quickly (instantly? Femptoseconds?) leading to Foxy's annhilation.

    Thanks guys, that explains it...i'll come up with a another random thought soon.... much much worse then the circular mirror or this one....

    so ... a black hole of an electron size, while disappearing, will destroy the universe.

    are you serious

    will destroy the universe.
    Who said that, as i figure they mean total annihilation inside the sphere, as in all the mass would destroy one another and form a form of energy....

    If the sphere was truly indestructible, the reaction inside would be
    prevented from expanding, and would be snuffed out or prevented
    altogether.
    I came in to the world with nothing. I still have most of it.
