1-in-1,000 Chance of Asteroid Impact In ... 2182?

astroengine writes "Sure, we're looking 172 years into the future, but an international collaboration of scientists have developed two mathematical models to help predict when a potentially hazardous asteroid (or PHA) may hit us, not in this century, but the next. The rationale is that to stand any hope in deflecting a civilization-ending or extinction-level impact, we need as much time as possible to deal with the threatening space rock. (Asteroid deflection can be a time-consuming venture, after all.) Enter '(101955) 1999 RQ36' — an Apollo class, Earth-crossing, 500 meter-wide space rock. The prediction is that 1999 RQ36 has a 1-in-1,000 chance of hitting us in the future, and according to one of the study's scientists, María Eugenia Sansaturio, half of those odds fall squarely on the year 2182."

      Simply making a comparison to a cargo cult might be rhetorically fun but it doesn't actually help. First, almost no one is claiming that they have high confidence in cryonics. Indeed, most proponents of cryonics estimate fairly low chances of it working. For example, Robin Hanson estimates around a 5% chance that cryonics will actually work http://www.overcomingbias.com/2009/03/break-cryonics-down.html. Indeed, when proponents have low confidence like this, claiming that there's a cargo cult mentality fails pretty miserably. Note that just because part of a technology hasn't been fully developed doesn't mean we can't make estimates about the technologies viability in the future. To use a fairly silly example, the largest hard drives today are a few terabytes. I can confidently predict that there will be 40 terabyte hard drives even though no one has made them yet. Note that cryonics proponents aren't claiming that we are anywhere near the tech level we need today. The primary claim is that from what we understand of the brain, the relevant information is preserved close to completely intact in cryonic preservation. That's the central claim. If one agrees that that is likely, it becomes highly likely that we'll eventually reach the tech level to be able to repair that functionality.

Another impact candidate is 1950 DA, which has a 1/300 chance of hitting Earth on March 16, 2880.
