Frank on Science!: Black Holes

Laymen love black holes because they sound so menacing and make great plot points for cheap scifi, but most people don’t tend to understand them. First off, it’s not a hole. It’s a ton of mass crushed into a single point. Second, they’re not black; they’re turquoise. Thirdly, they don’t suck things into them anymore than anything else with mass. If the sun was suddenly replaced with a black hole of the same mass, the earth’s orbit wouldn’t be disturbed at all. It would just be dark and we’d all freeze to death, but otherwise we’d be fine.

One interesting property of a black hole is its the only thing we know of that destroys information because everything that goes into it gets collapsed into only three points of data: mass, charge, and angular momentum. Like if you had data you don’t want anyone else to obtain, run a wipe program and throw it in a black hole. It will be gone for good that way (unless you were trying to protect your data’s angular momentum from prying eyes). Hopefully someone has a sign up telling you where the event horizon is, though, because black holes can be dangerous that way.

Anyway, let black holes be a warning to you. We all love matter and use it every day, but sometimes it collapses on itself and rends space and time. That’s dangerous. If you see matter collapse on itself, get as far away as possible and contact your nearest scientist. And whatever you do when confronted with a black hole, don’t put your tongue on it.

Despite the existence of black holes having been calculated for some time, they’re still pretty much theoretical. I’m sure, though, there will eventually be a Mythbusters episode where Jamie Hyneman and Adam Savage travel to the center of the galaxy and throw a rock at one while filming the results with a high speed camera, confirming most of the theories.

  1. You miss the point of Black Hole Theory. Everyone misses it. The real point is about how to tax it so that everyone finally gets it. It’s the Anti-Cummulative Inverse to Matter. It’s a simple question, really:
    Q. “What’s the Matter?”
    A. “Nothing.”
    Political/Science! response: “He knows too much. Tax him.”

    Ah. Crap. My head just exploded, again. What were we talking about?

  2. You are so Racist! with all your talk about black holes, Frank, and your hiding behind Science! doesn’t change that one little bit! You’re just trying to make people think the Barack H. Obama is going to crush everything in the US and destroy everything except our mass, charge, and angular momentum. Racist!

  3. The sun is radiating out a lot of mass now, whereas if it was a “black hole” it would lose mass only through that very very dim turquoise radiation you mention. I think our orbit would decay if the sun was a dark turquoise hole.

    Dark turquoise holes aren’t compressed to “a single point”; they’re compressed to the radius where the escape velocity is the speed of light – the “event horizon”. You’ve mentioned the event horizon already, I’m just explaining it :^)

    We haven’t seen any dark turquoise holes, but we infer them – through gravitational lensing (which you are depicting), and also through X-rays. “But X-rays aren’t turquoise!” says the monkey. The appropriate response to that is, “shut up, monkey, it’s obvious I’m talking about the intense energy emitted by stuff going real fast toward the ‘hole”. And then duck his poo.

    One last thing – we would never observe a mass-bearing particle entering the event horizon. The closer the object gets, the SLOWER it APPEARS to the rest of the universe. So, if we put Harry Reid near a dark turquoise hole, we could come back 40 years later and he would be a little closer to the ‘horizon, but he would only have aged, maybe 10 years, or a day, depending on how close he was when he started. (And the guy is so decrepit anyway, who’d know?) So we couldn’t in practice make anything lose information this way.

  4. One interesting property of a black hole is its the only thing we know of that destroys information

    Oh, no, it isn’t. There’s the New York Times, the San Francisco Chronicle, and all them. Not to mention Harry Reid and Nancy Pelosi. And the blobfish who’s Obama’s press secretary; after much work, I’ve succeeded in forgetting his name.

  5. RACIST! Everyone knows the entire black hole theory was created by white males in the age of white supremisist oppression of all non-white peoples, and females. Not until fully half of the worlds scientists are non-white females can this card be placed back into the deck for fair play. And don’t even get me started on black matter.

  6. you don’t have to go to outer space to see a black hole. All you have to do is fly into Reagan International Airport, get on the train, go down to the Mall and look for the Crapital.

    There is it, the biggest, baddest, blackest hole ever seen.

    Too bad we can’t simply close it up and walk away.

  7. Somewhere in a universe Karl Schwarzschild is crying because he just found out black holes are turquoise. Not only is he going to have to change his name to Türkischild, he’s also going to have redo all his geometry. FrankJ, you are so cruel!

    PS: Physics! isn’t the supreme Science! because it’s susceptible to breadcrumbs. Geology! is the supreme Science! because it’s got volcanoes and earthquakes and glaciers and dirt and stuff, though the Blobfish is so cool I’m willing to give Biology! an equal share of the supreme platform for a while, too.

  8. Corona, you sly Devil you. So we should refer to Jesse Jackson and Al Sharpton as People With The Complete Absence Of Color Within The visible Spectrum? That’s a mouthful. But maybe after trying to say that, those two fat bloated race-baiting idiots would be too distracted to notice us throwing them into Black Holes.

    And Frank, what do I do if I want to keep my Angular Momentum private?
