A Quantum Bomb

  1. Jul 1, 2005 #1
    I propse a new scalable weapon of mass destruction with
    potentially unlimited destructive power. I call it the Quantum Bomb.

    It consists of a 1000 Kg Bose-Einstein condensate. Pick your
    favorite atom. Hydrogen perhaps for a big fusion explosion?

    To explode the bomb, you let it "warm up" and watch it go :surprised Boom.

    The power of Pauli's "Extermination" Principle ? :eek:

    Ack. That's a horrible proposal! Why would you want to propose such a thing?

    Scientists should be fostering the good in humanity, helping it through innovative technology (which can be used to save lives), not blasting it to smithereens.

    Save lives? nooo. We don't want to over-populate the earth even more with humans.

    I think we've reached a point where we're rather good at blowing things up on massive scales. I dont think we need any new innovations in that field.

    An antimatter bomb must be near the theoretical limit for maximum explosive power per kg. Not only is the entire mass converted to energy but also an equal mass of it's surroundings!

    Only an idiot would try and make one tho'.

    One of my physics proffessors went crazy this past semester. One of the ideas he ranted at us about (when he was still holding lectures) was the "quark bomb", which of course would release quite the amount of energy!

    Since this is a "science" thread, would you please explain the science behind this ?

    What problems could be solved by using a bomb with "potentially unlimited destructive power?" A means of mass-suicide?

    Well, Venus is getting rather annoying as of late....

    I presumed he was referring to some recent reports where fermions teamed
    up in pairs at ultra-low temperatures to become a BEC. Such a condensate
    is highly compressible. At slightly higher temperatures however the pairs would
    become unstable and Pauli's Exclusion Principle would kick in...

    Regards, Hans

    Hans, I get that part.

    This, I don't :

    He might see this as just as a side effect, (H-bombs need an ignition source)

    One can wonder about the peaceful use of such an idea of bosonic compression
    followed by fermionic expansion. :tongue: So where would the energy come from?...

    Regards, Hans

    would such a thing be "charged" by absorption of photons?

    (I've been away for the Holiday)

    Yes, Hans has expressed what I was thinking.

    Interestingly this thread has taken a political turn which I was not
    intending but was half expecting.

    People who will (or are) persuing a career in Physics have a responsibility
    to advance science. There is no way to prevent the ill-intentioned from
    using new ideas for weapons and (in my opinion) we should not censor
    our ideas because they have weapons potential.

    The ancient scientist who invented the club probably used it to survive
    but he or she may have used to it dominate their fellow men. Inventing
    it was not evil. Clubbing their fellow man over the head probably was
    (unless it was a case of self defense.)

    The important question for us is, who should get the first crack at your
    weapons ideas? The good, or the evil? And then you have to decide how
    best to identify who is who.

    Still, this happens ALL THE TIME in a superconductor when you warm it up above Tc, yet you see zero explosion of any kind. And unless I missed it, Deborah Jin and her colleagues at JILA are still alive after doing the same thing with their fermionic condensates.

    So what's the "explosion mechanism" here? It's obvious from experiments already that the "rapid expansion" isn't THAT rapid.

    This may be hopelessly naive, but couldn't a formidible nuclear fusion reaction
    take place if you had a few thousand kilograms of alpha particles occupying
    the space of only one?

    And how would you propose to do that?

    I don't know about the alkali atoms, but the highest BEC densities achieved in He4 are of the order of 1014/cc, I think. This is 8 or 9 orders of magnitude less dense than a piece of steel.

    Exactly!

    I think people are confusing the BE scenario of condensation to the same "state" as meaning being in the SAME location. The latter isn't necessary for a BE condensate anymore than for fermions.
