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."
I imagine some people have, or plan to have, children which they will have some degree of fondness towards. As it may effect their children, or their children's children, it might be of some concern to you.
Also, I'm pretty sure an unusually high percentage of Slashdot readers are not planning on dying. I mean, that's pretty much what science is for, right? I'm very concerned about how this asteroid will affect my robot-body . . .

Sad reality: if the robot-body technology WAS developed within our lifetimes, the vast majority of us couldn't afford it. That's going to be the ugly truth when it gets here: "immortality" will only be for the rich. The rest of us will live and die like we always have.
That said - 500 meters? That's enough to cause some SERIOUS devastation, but it's not an extinction event impact. 6 miles wide killed the dinosaurs, but didn't wipe out EVERYTHING. This is 0.3 miles wide. As long as civilization as a whole goes on then I'm not TOO worried. Afterall, if they fail to successfully deflect it, the survivors could look at it as a learning experience.

I seriously doubt it. Humans are adaptable. Sure, we may go into another Dark Age in the next century or so, but the issues you show concern over would fall pathetically short of causing our extinction.
So, let's hear the libertarian solution:
Statistically, we've probably discovered 1% of the potentially hazardous asteroids. Now we have a data point for an interesting occurrence: one of the ones we know about has a good chance of hitting us. What about the rest of them?
How we know is more important than what we know.
More like 72 years. NASA says that they would need to start actual diversion operations 100 years in advance, which leaves 72 years to figure it out.
2182 - 2010 = 172 years
Subtract 42 ( Life the universe and everything ) And you get 130 ( Hold this thought )
In 1951, Bobby Thomson hit the "Shot heard round the world" (i.e The Asteroid)
Against the Brooklyn Dodgers...(i.e Earth trying to "dodge")
Take 1951 and turn it into a repeating Decimal .1951951951........ ( this is wrong but who cares )
Then take the above 130 and divide by the repeating decimal and you get....

Not only you. The whole human species would be extinct by then. We have global warming, pollution, fuel shortage, wars, corruption. These are enough to finish us by 2100. What happens in 2182 is irrelevant.
Dammit, and 2182 was finally going to be the year of Linux on the desktop!

A rock like this heading to our planet and we've got plenty of time to not just deflect the thing, but to move it into Earth orbit where it can be mined, turned into an outpost, and be used as a tether for a space elevator.
Sad reality: if the robot-body technology WAS developed within our lifetimes, the vast majority of us couldn't afford it.
Oh I'm sure that banks will be willing to give you a loan to purchase (or better still - rent) your immortal robot-body, after all - you are going to have hundreds of years to pay it off.
I know some executives who would salivate at the idea of having an indentured workforce like that.
You can never know everything, and part of what you do know will always be wrong. Perhaps even the most important part.
We cannot predict the course of asteroids over 200 years to within an Earth diameter. I have worked on this area, and the masses and positions of bodies (particularly all of the other asteroids) are simply not well enough known. So, it will come near the Earth, but we won't know if it is a true threat for at least a century.
But it has no torino scale entry because the torino scale is only defined for impacts in the next 100 years. Hence it is listed as n/a.
And the impact probability you cited is the cumulative probability of 8 events. There is only a probability of 5.4E-04 (1/1850) of an impact in 2182.
I don't quite get the publicity at the moment. It has been at that level for quite a while and is still at a much lower level than (99942) Apophis was (which hit 1% chance). In all likelihood new data will rule out an impact.
It would probably turn out to be a Tax dodger.
Maybe an big import tariff?
Not only you. The whole human species would be extinct by then. We have global warming, pollution, fuel shortage, wars, corruption. These are enough to finish us by 2100. What happens in 2182 is irrelevant.
Not really. The human race started off as a primitive ape like species. We managed to survive living in jungles, deserts and caves. How is "global warming, pollution, fuel shortage, wars, corruption" going to kill ~7bn people. Sure it might kill 3 billion or even 4 billion at the very worst (which is still unlikely) But there is no way any of the things you mentioned will kill every single human being.
"artificially restricting its availability to the financially privileged would cause a mass uprising among the informed."
Yes. The thread, here in Slashdot, will probably reach the 1000 comments.
Image 13 boxes each containing 13 revolvers.
One revolver has one bullet in it.
Now imagine being offered $100,000 to pick a box, and then pick a revolver and then shoot yourself with it.
That 1000:1 odds.

Freezing is not the problem, thawing is. Also, do these cryoprotectants work on cell level so the walls aren't punctured by ice crystals?
Yes, they do. This problem was solved for in the late 90s by using much more advance cryoprotectants which allow the body to vitrify at low temperatures rather than freeze. This has been true for about a decade now. Indeed, they've now successfully brought rabbit kidneys down to liquid nitrogen temperatures and brought back up, transplanted them, and had the kidneys function. See http://www.cryonics.org/reports/Scientific_Justification.pdf which includes discussion of this and other research (including direct examination of vitrified rat brains which show the cellular and synaptic structure largely intact.)
Not immediately but quite possibly it could indirectly. All the trivially accessible minerals, oil etc have been consumed. Another dark age and we're likely stuck there indefinitely, possibly forever since we wouldn't be able to boot strap through the equivalent of the 18th, 19th and 20th centuries.
Getting stuck in that state may prevent our ability to overcome the next hurdle. We're smart but we need resources.
