    This should be called a "darkhole" if anything, rather than a blackhole. Also, the people who call it a "blackhole" shall be labeled as "assholes" from now on.

    The great Psychonaut has spoken. All things extant in this world, Gods of Heaven Gods of Earth, let everything be as it should be. So mote it be.

    @psychonaut2021: Agreed, calling this device a black hole isn't just highly disingenuous, it's utterly wrong.

    This device simply traps light, and by means of its design, disallows the electromagnetic wave from being released, forcing it to be converted directly into heat energy once it reaches the center. #tabletopblackhole

    Even if it was a real black hole, it would not necessarily mean the end of the world as some think. A black hole is after all made from atoms. They are just very compressed. A black hole made from 2 (e.g.) hydrogen atmos, would still only weigh as much as two hydrogen atoms and have the same gravitational pull as those two atoms have.
    If it was one gram of hydrogen, the black hole would "weigh" one gram and it would "have the same gravity". It would just be in a very small spot. Which is good, because it means that it would probably never get to "eat" anything ;).
    Now that does not sound that scary anymore after all, does it?
    Also, small black holes tend to evaporate really quickly.

    It's a trap, not a black hole in the classical sense (since gravity is not involved in any way).

    If it were a real black hole with gravity so strong that it sucks up everything, we wouldn't be having this conversation. Unless the black holes don't work that way... Or something.

    @Mr. Damage: If the sun were to turn into a black hole today, skipping that whole blowing off the outer part bit, the only difference we'd see from here is it would get dark really quick. It wouldn't suck in the solar system, it wouldn't even suck in Mercury.

    @Barry99705: Not right away. Still, if you're not sucked in right away, there's other issues.

    But to point at hand, this isn't black hole since gravity ain't involved. #tabletopblackhole

    For those baffled, it's from Isaac Asimov's amazing short story, The Last Question. Which pertains to entropy and curiosity as to the means of reversal thereof, and is definitely worth a read.

    Maximum entropy is not about molecular motion, it's about energy distribution; basically, all the energy in the universe will eventually become heat, making it a very warm, very dead place.

    @QuarterToTomorrow: wrong, it will become colder. It will be a cold, dead place. There was something in the article that mixed heat death and entropy, but I am too tired to figure out what went wrong there...

    @yogibimbi: As I understand it, the universe will get warmer on average, which will leave it still a very cold place.

    Most of the universe, now, is really, really cold. We happen to be on a bit that's not. In the entropic death of the universe, all energy would be heat, pretty much evenly distributed. The average would be higher than it is now (but still near 0 Kelvin), but there would be no hot spots like us up at 310 K or wherever we are.

    So, yeah, it'll be cold and dead. Dead, because life requires an imbalance in energy distribution to drive it; cold, because it will be only a bit warmer overall than the near-absolute-zero it is now.
