Rand Expert Says To Keep Mum About Killer Asteroids 415

Posted by timothy from the ignorance-is-the-end-of-the-world dept.
crashnbur writes "NASA is conducting a survey of the sky to find asteroids large enough that a collision with earth could 'extinction-type impact', and none studied so far will threaten us in the next 200 years. Of course, if a doomsday asteroid is discovered, the current policy is not to say a word: 'If you can't do anything about a warning, then there is no point in issuing a warning at all', says Dr. Geoffery Sommer. The issue may be making its rounds because an asteroid was discovered orbiting the sun between Venus and Earth earlier this week. Space.com presents a lengthy, four-part 'Impact Debate' (next three parts coming next three Tuesdays). Apparently we are just as likely to die by asteroid impact as in a plane crash."

Now think of those who already say to hell with the law and do whatever the heck they want. Now imagine what happens when law enforcement that CAN'T be effective anymore because the amount of crime has jumped a hundredfold and they can't cope.

      I don't think so; not yet, anyway.

      Look at it this way: If, over a 10 year period, 100 people die each year in plane crashes, then the total will be 1,000 deaths.

      However, it only takes one event for a meteor to kill as many people. Same ten year period, but no meteor deaths until the last minute of the last day in the tenth year, a meteorite strikes the earth and kills 1,000 people.

      Statistically, the odds of dying either way are the same.

      So, right now, we have lots of people dying in plane crashes, but no one dying from meteorites. But when a meteorite strikes the earth, it is estimated to kill as many people as plane crashes have.

      Very simplified. I'm sure someone will want to flame me and clean this up a bit....

        Your conclusion is roughly correct as far as the stats goes. But what I think you've really done is illustrate why statistical and probabilistic models are basically worthless in the real world, and especially at (and between) extremes. It's kind of like asking whether it's worth spending one dollar on a 6/49 lottery when the jackpot is worth 7 million versus 14 million - how much is the "dollar" worth. It's an intensely reductionist phrasing of the question that ignores the surrounding reality (in this case, that winning the lottery is winning the lottery, period).

        Losing the asteroid lottery is completely unlike losing the airplane lottery. The comparison is useless; it's really a type of argument by analogy, which is a fallacy. I realise it's someone's attempt to make things understandable to the lay media (or push an agenda there), but it does nothing besides muddy the issue.

        The truth is that people can't wrap their heads around probablistic assessments anyway, so trying to make persuasive arguments to the masses that way is folly. And making a probabalistic comparison between two such different things borders on dishonest.

      • Probably because not all asteroids would fit the profile of an inevitable extinction event. There are probably smaller ones that we can do something about,

        Dinosaur-killer sized asteroids only come around every hundred million years or so; the last I had heard we had recently acquired good orbital data (good in both the "accurate" and "not going to hit the Earth any time soon" senses) for over 90% of the asteroids with orbits crossing ours and diameters over 1 kilometer.

        The problem is that asteroid populations are disproportionately distributed among smaller sized rocks; asteroids large enough to flatten a small city or cause a small tidal wave may come along every few centuries. It would be nice to start looking for those too.

        given a fair enough lead time.

        The lead time is the important thing, isn't it? Even if there is a supermassive asteroid that is going to smash into Earth, if we found it with a few centuries lead time before impact then there are lots of options for protecting ourselves.

      [poster asks why bother searching for killer asteroids if we can't stop them]

      Because if we can detect one early enough, say a few years out from impact we might be able to do something about it.

      Remember, way back in the 60's we put men on the moon , thus jump-starting the next 50 years of technological development basically just to make an idealogical point.

      Imagine what we could do if the whole ball of wax was at stake, and where it would take us after we'd saved ourselves. It took a decade to get from simple flights just outside the atmosphere to playing golf on the moon. Given a decade to stop a dinosaur-killer from hitting us we'd probably develop fleets of single-stage-to-orbit spaceplanes, huge advances in materials and propulsion etc. Hopefully once outside Earth orbit we'd stay out there instead of pulling back like we did last time. And it'd be nice to think that after being faced - really faced - with possible extinction, there'd be even just a subtle shift in our global psychology; it brings me to mind of Reagan's famous speech where he wondered what we'd be capable of as a species if we had to band together against some outside threat...

      Though having said that my guess is we'd probably all be back to watching Springer and slaughtering each other within six months of it all being over. Granted, I say this before I've had my morning coffee so I may get a lot more optimistic once the caffine kicks in...

    • From the Near Earth Asteroid Tracking project [nasa.gov] FAQ:

      If we were to discover tomorrow that a comet or asteroid is on an Earth- intersecting path, what could we do about it? What would you recommend doing about it?

      Actually, some 100 bodies have already been discovered on orbits which take them so close to the Earth's orbit, that they could hit in the far distant future. This is because the orbits of these bodies change slowly with time. Although their orbits do not intersect Earth's orbit at present, they could hit in a few thousand years or more.

      The scenario you have in mind is most likely to unfold as follows. In the course of our search for Earth-crossing asteroids, we could find one that will hit not in the next year, or even in the next ten years, but might hit in the next hundred years. We believe that the chance that we will find such an object is only 1 in 1,000, even after a complete search. If we do find such an object, we will have plenty of time to track it, measure its orbit more precisely, and plan a system for deflecting it from its current orbit (hopefully away from the Earth's). There will be no great hurry, and no great panic. It would be a project for all the world's nations to take part in. It could be a globally unifying event. Because we will have found it long before it actually hits the Earth, it probably would take only a small impulse (chemical rockets, or perhaps mass drivers) to divert it from a threatening path.

      There is a much smaller chance that we would find one that could impact in the next 10 years. The chance of that happening is 1 in 10,000. If this were to happen, we would probably still have time to launch a crash program of scientific and technological research, with the goal of characterizing both the structure of the menacing asteroid, and the best means for diverting its orbit.

      The least likely scenario is that we would find one that could hit in the next year. The chance is 1 in 100,000. In that case, there is probably little that we could do to divert it.

    • How about: we can't do anything about it right now because people aren't willing to invest in a project that researches ways of moving asteroids. Spotting an asteroid years before it hits us gives the chance for the world to work together to work on a plan to get rid of it and try several times. Giving it a nudge while its still years away its more likely to affect its path near Earth then it is to hit it a bit when its right near us.

    Except one of the situations happens often enough to make headlines multiple times every year...and the other doesn't. So why are they listed as the same?

    My guess is that somebody was considering that a great number of people would die as a result of a large meteorite impact. Taking this into consideration, then over a long period of time (long enough to include one or two significant meteorite impacts), then yes. If you counted the number of people that die from meteorite impacts and those that die from the sum total of all plane crashes, then they might be equal. But this is statistics, not probability. The probability of being killed by a meteorite would be much much lower.

    The same thing is seen in a coin toss. For instance, say that you have flipped a coin six times, and each time it has landed on 'heads'. Statistically, you know that only 50% of flips will result in 'heads', so you might think that the odds are very low for the coin to land on 'heads' a seventh time -- 1 in 32 or so. BUT the seventh flip has the same 50/50 chance of landing on heads that any other flip had. That's probability.

    • Uh, no.

      If, on average, a certain even over the course of a long time has some chance of happening, like, say, a plane crash or an asteroid hitting, then it's reasonable to compare them. If an asteroid hits, a ton of people are going to die, but it's unlikely. If a plane crashes, relatively few people are going to die, but it's much more likely.

      The thing that isn't being taken into account is variance. Asteroid impacts are low-probability, high-variance events, kind of like winning the lottery in a really bad way. But, like the lottery, when it hits it has a much bigger impact.

      So if I bet a dollar, and half the time I lose my dollar, and half the time I get back my dollar plus another 50 cents, I would expect to win as much money on average as if I bought a lottery ticket. The money won, on average, is the same. It's the same concept, except instead of dollars won in this case, you're picking people from the population to die. Grim, I know.

      It seems to me that in a world of restricted resources, you should tend to put those resources not necessarily in the place that has the highest number of expected deaths, but rather in the place that will lower the number of expected deaths the most. So I think it's reasonable that we spend more money on airplane safety than on asteroid detection.

        except if the 'long time' in which the certainty needs to happen exceeds a person's lifespan. that is why I bring up statistics vs. probability. statistically, over this 'long time' there might be as many people die from planes as meteorites.

        but, that 'long time' is almost definately much much longer than your lifespan or mine. therefore the probability of me dying from a plane crash is much greater than my probability of dying from a meteorite.

        now I'm no math expert, this is just my opinion generated from my limited knowledge. But probability is what defines every instance, versus statistics which are used to find out general patterns. This is where my coin analogy came from.

        To look at this with another example, take the Black Death. It was a significant event, with large variance. Lots of people died. So, the history of the last 1000 years might show that 1 in 400,000 people die of the black plague. So does that mean that my odds are 1/400,000 in dying of the black plague? No, the probability is much smaller than that because probability must look at my lifespan, and events happening in my lifespan. Things that happened 700 years ago are as unconsequential to my lifespace as things that will happen 700 years in the future.

        though you do bring up good points :) especially the fact of variance

      The analysis is the same if you want to discuss probability of dying in either event. There is a very good chance that there will be a plane crash (several, in fact) during your lifetime, but a relatively poor chance that you will be on one of the crashed planes. On the other hand, there is a very low likelihood that an asteroid will hit the earth, but if it does, there is a very good chance that you will be killed by it. This is why statistics and probability are very closely related, since the number of people killed in an event affects your probability of being one of those people (the more people killed, the more likely you are to be one of them, all other things being equal).

    statistics comes in handy.

    I've known several people who have died in plane crashes ( one of whom ended his life against the World Trade Center). I've never known anybody killed by an asteroid. Neither have you, or your parents, or *their* parents.

    This statistic is derived because relatively few people die in plane crashes, whereas *IF* an asteroid hits a great many people will die.

    Technically, mathmatically, the statement is correct, but really has nothing to do with whether or not *you* will die by being hit with an asteroid.

    It's this same misunderstanding that leads people to believe there were no old people 200 years ago, because the *average* age was low. Whereas a quick study of the death age of America's founding fathers would put the lie to that idea.

    The low *average* age is heavily weighted because so many people died before they were two. . .days old. The so called "Life Expectency" has absolutely *nothing* to do with how old any particualar person might be at their time of death.

    So don't bother spending the rest of your life looking over your shoulder for asteroids. *You* are far more likely to die by having a plane fall on you.

They won't keep it quiet. So, if there is such an asteroid on a collision course with earth (which there is, somewhere), the odds highly favor it being discovered by an amateur astronomer who will immediately tell everyone which makes this entire thread moot.

    It's been something like 200 million years since the last "extinction level event". If they happen statistically at random this suggests that the chances of one happening in the next 200 years is only one in a million. Not one in a million per year, or per rock, or per observation - one in a million total over the next 200 years. And that's assuming that we can't or don't do anything to improve the odds.

The idea has been defunct in the medical world for many years. In the US it is extremely unethical to do this, though I am sure in some countries it goes on. The reason is quite simple - with a limited time left on the world, there are likely many things the cancer patient would like to do before he dies, e.g. apologize to that guy he was a dick to at work, tell some girl he loved her, beat civ3 on the hardest level.

    On top of that, it is just plain dishonest. Not to mention that in the case of an asteroid, someone somewhere might have a bright idea that would avert disaster or extend human survival.

    Look, if there's a killer asteroid on its way, there will be no way to keep that quiet. At the very least, people will begin to wonder why astronomers all over the world are suddenly entering seminaries in droves, engaging in bacchanalia, and living lives of extreme hedonism.

    Nor should there be any reason to fear a so-called "killer asteroid." There have got to be ways to fight back. Here is my own, back-of-a-napkin plan.

    1. Calculate when the killer asteroid will hit. Because it's big, it will most likely be spotted years, if not decades in advance. The more time, the better.
    2. Locate many large, nearby, non-killer asteroids.
    3. Build many nuclear warhead-tipped rockets.
    4. Fire the rockets at the smaller asteroids at such angles as to cause these smaller asteroids to deflect into the orbital path of the killer asteroid. Focus on hitting the killer asteroid on its dark side, again and again, so as to move it closer to the sun, to take advantage of the sun's gravity.
    5. The killer asteroid should just miss the Earth on the side closest to the sun.
    6. If successful, make a dramatic motion picture of the event. (Optional)

    Of course, there is no need to actually send the killer asteroid into the sun.

    Surely improvements could be made. The point is, we can indeed fight back. It would be stupid and cowardly to not try.

    In any case, we should bear in mind that it is extremely improbable that a killer asteroid will hit in our lifetimes.

    When a large enough asteroid hits, it will scorch a significant percentage of the planet's surface, and black out the sky for many years, throwing the planet into an ice age. As a result, most life on the planet will die. This has happened many times before.

    Yet something survived. Something was able to withstand the ice age until it receeded, and it was enough to maintain the ecosystem, so both animal AND plant life persevered. Somehow. That means, despite how horrible it would be, there would be a CHANCE that humans could survive. Granted, life as we know it would be over, but we could find a way to hold out, hundreds of years if we had to.

    The chances of any of this being possible relies upon the amount of time we've had to prepare. If we have minutes, then yes, there's little we could do. But if we have years, months, even days, there's plenty that could be done. The impact area would be known far enough in advance that it could be completely evacuated. Deep caves could be built to house the population of the world. Lord only knows, if we REALLY wanted to, we might find a way to push that asteroid out of the way in time.

    And besides, how exactly would you keep it a secret? Half the space objects discovered are done so by people and equipment not under control by the government. Remember the 1 mile asteroid discovered a few years ago with a SLIGHT chance of hitting Earth? Even before they knew for sure that it wouldn't, it was on the front page of the newspapers. It was the effort to notify other scientists for peer review on the projected orbit that the press got wind of. There is no effort to keep these things secret, so how would you suddenly shut everyone up once several hundred people were aware of it?

    The smaller asteroids can be just as dangerous. Something 50 to 100 meters wide, similar to what hit siberia in the early 1900's had a devastating effect locally, but today, if people didn't have advance warning, you better hope people figure out what it was before they start launching retalliation nuclear strikes.
