    Eh. So they created something "like a black hole" for electrons. So is my 6 year old when it comes to food (specifically anything made out of carbohydrates.)

    beware carbohydrate addiction.
    (they do not get addicted to the carbs, they get addicted to the endorphines that are released by the brain from eating lots of carbs, which then makes them vastly more prone to addictive disorders)

    allowing children to eat lots of carbs unchecked while not exercising at least 10 hours a week on top of normal activity will lead to big issues.

    That the molecule blew up is not interesting to anybody , seems odd .

    = entropy ?

    So what ? Continue

    Why would entropy leed to an explosion of the molecule ?

    Yes this breathless report seems utterly unremarkable.

    X-rays excite core electrons and with the right frequency can ionise them, leaving a vacancy in an orbital in the core, which will be filled by a electron dropping down from a higher energy orbital. What they did was ionise all the electrons in the core, so there was then a huge cascade, which (obviously) would involve those electrons in the valence shell that are involved in bonding. These electrons are in molecular, rather than atomic, orbitals,which are populated with electrons from both the atom being irradiated and the ones it is bonded to. So those electrons too will get involved in the cascade process.

    This, equally obviously, will break bonds and make the molecule disintegrate. All this crap about "black holes" and molecules "blowing up" looks like ridiculous hyperbole to make something totally predictable seem like a new discovery.

    The burning question this would appear to raise is, "So what?"
