There are new rocks created on Earth every day, whereas some meteorites are the same material that went into planetary formation. I’d be impressed by the age of such a lump too.
Hamilton says that her insurance company will be doing a walk-through to see if roof holes cause by space debris are covered. Evidently, the company has never had a claim filed quite like this before.

As for Hamilton, she has no plans to take up astrology or stargazing after her encounter.
Pleasantly down-to-earth.

I would like us to contemplate, for a moment, the staggering cosmic scale of this saga that has concluded with a sentient, self-aware observer narrowly avoiding the premature end of their sentience by random space rock, delivered while they were unconscious of their self-awareness. This is, without exaggeration, an insanely complicated story billions of years in the making.

The forces that caused that meteor to land on that person's pillow and nott their heads are older than the person, older than the idea of pillows, and are likely older than life on earth.

Oldest dated rocks on Earth. The average age of Earth's crust has been estimated at about 2 billion years. I believe most meteorites originated as asteroids and comets formed along with the rest of the solar system, about 4.5 billion years ago. The oldest known meteorite is the Murchison meteorite, dated to 7 billion years old and predating the formation of our solar system by 2.5 billion years.

Meteorites aren't especially rare, but ones collected from observed falls are somewhat more rare. As of August 2021, the Meteoritical Bulletin Database recorded 1211 observed falls. If this particular meteorite is valuable, it will probably be because of the unusual story of its fall.

Not only would it be a space rock, it'd probably be a piece of Halley's Comet, since we are in the midst of the Orionids, which happen every year about this time as we pass through the comet's debris-filled orbit.

The Orionids are not the most abundant of showers, but at ~148,000 mph, they are the speediest.

Some of the components of Halley are like carbonaceous chondrites, which are old because they condensed out of the rotating nebula which became the solar system very early, and some are even pre-solar, such as the Murchison meteorite mentioned by biogeo.

But I couldn’t find anything which specified the age of Halley's constituents directly.

A rock floats alone in space for billions of years, and then in a moment of a moment of a moment it somehow finds itself in a gravity well that takes it to a soft pillow.

My understanding is that by the time most meteors reach the surface, they've bled off enough energy to friction that they will be travelling at or near their terminal velocity in atmosphere, not the incredibly high speeds they're moving relative to Earth when they first enter the atmosphere. And while the exterior of the meteor can reach very high temperatures due to that friction, much of the exterior layer can actually ablate off and carry that heat away with it. Furthermore since the meteor starts out in thermal equilibrium with space (and is thus very cold), its thermal mass means that even with quite a lot of surface heating, its temperature by the time it lands as a meteorite is still quite cold even with all the heating from air friction. I'm not enough of an expert on these things to be sure that I haven't been misinformed on this, but it's what I recall learning, and I think it makes sense to me at least.

None of which is to say this couldn't be a Jesus-on-toast sort of situation, just that I don't think the facts about the speed and temperature of the meteorite are necessarily inconsistent. This is certainly a pretty improbable event and it would be more likely to occur due to some human contrivance. However, very improbable things are highly probable to occur, as long as we don't specify which improbable things a priori.

I believe the vast majority of heat during entry is produced by air compression, not friction.

From a follow-up article:
[Peter] Brown is Canada Research Chair at Ontario’s Western University and has been a researcher in this field for 30 years. He said an opportunity like the one in Golden only presents itself so often.

'When we first heard this story we were pretty surprised, but also pretty convinced that it was a meteorite and we certainly had a pretty good idea of the fireball that was related to it,' he said.

[…] Brown says it’s also not a shock that the rock did not burn the bed when it landed, as meteors stop being luminous at about 18 to 20 kilometres of altitude, giving them plenty of time to cool off in the chilly upper atmosphere.

What are the chances of being brained by a second space-rock after being narrowly missed by the first? By this logic crossing a street should absolutely terrify you.

Exactly the same as the chances of being brained by a space-rock generally.

I think the Bayesian probability might be a little different:

P(brained by space rock)|(already brained once by space rock) << P(brained by space rock)|(not yet brained by space rock)

However,

P(almost brained by space rock)|(already almost brained by space rock) ~= P(almost brained by space rock)|(no prior)

This may have changed. Meteors are quite expensive on open market these days, there's a lot more science and space nerds out there willing to pay relatively high prices for confirmed meteorites, especially largish ones any bigger than about the size of a pebble or plum.

And anything with a story like this probably commands a premium.

Hang on, scoping out eBay.

Oh, I guess not. No, you're right. It looks like you can't pay for a new roof with the meteor that wrecked it unless it's a really big one, and, well, then you'd be looking for a whole new house or even neighborhood.

Even the auctions that look legit and verified are going for only a few hundred to thousand per kilo, but the really big ones rapidly climb into the tens and hundreds of thousands.

It looks like there's a few auctions where they've been witnessed or have a story have some crazy high prices per kilo but that doesn't mean they will actually sell and the auctions for those look... ah, kooky.

Well, from a frequentist perspective I'd argue that if P(brained by space rock within time interval T) is independent and identically distributed for any T, then the relevant probability isn't conditional but joint.

P(brained by space rock | almost brained by space rock) = P(brained by space rock), because "brained by space rock" and "almost brained by space rock" are independent events.

However, P(brained by space rock AND almost brained by space rock) ~= P(brained by space rock)^2 << P(brained by space rock).

So it's a matter of perspective. If you ask a priori what the probability of being almost brained by a space rock and then being brained by a space rock, this is indeed much less probable than just being brained by a space rock in general. But if you ask, having already been almost brained by a space rock, what the conditional probability of then being brained by a space rock is, that's unaffected.

However, from a Bayesian perspective, we ought to use the information about being almost brained by a space rock to update our estimate of the overall probability of being brained by a space rock. However unlikely we think being brained by a space rock is, having observed it to almost happen once we should increase our estimate of how likely it is. That is,

P(brained by a space rock | almost brained by a space rock) = P(brained by a space rock) * P(almost brained by a space rock | brained by a space rock) /P(almost brained by a space rock).

If we think that P(almost brained by a space rock | brained by a space rock) ~= P(brained by a space rock | almost brained by a space rock), which I would argue is a reasonable guess, then because P(almost brained by a space rock) < 1, P(brained by a space rock | almost brained by a space rock) > P(brained by a space rock). Not however that the Bayesian interpretation of this isn't that almost getting brained by a space rock actually increases your chances of getting brained by a space rock, but rather that our estimate of the probability of being brained by a space rock increases following the information that one has been almost brained by a space rock.

Thanks for the opportunity to type the phrase "brained by a space rock" so many times. I was tempted to insert variables but typing "brained by a space rock" was too much fun.

It is a much, much smaller and possibly more romantic and interesting probability to talk about that this space rock would land on a soft pillow, than in someone's brain.

For one, there are many-fold more humans than pillows with which to collide.

Further, human targets are much more even distributed across the planet than pillows, and also have greater aggregate mass and gravitational pull. /science

Yeah, confirming what biogeo said above. There's a lot of reports of fresh but small meteorites being extremely cold if not solidly frozen to the touch on landing.

In the incandescent phase in the sky they're basically acting like ablative aerobrakes and the heat is being carried away by the plasma and material, then they reach terminal velocity and fall out of the sky like any normal rock would, and there's a ton of thermal mass in a cold iron-nickle rock the same way that metal out of the freezer would react, say, metal whiskey stones, or a frozen ice cream maker barrel.

Another way to think about this is in relation to the re-entry shields or the tiles of the Space Shuttle or similar aerospace technology. The only real reason why they need lightweight exotic materials for those ablative aerobraking and shielding is because of weight to orbit fuel and payload costs. There's no reason why you couldn't use a few tons of plain old iron slab for a heat shield and aerobrake instead of composite materials or ceramics besides the fact that it's extremely costly in the balance of vehicle weight to delta V and all of that fiddly cost per pound to orbit math.

A solid, roughly spherical chunk of iron-nickle alloy has a lot more thermal mass and general mass with the least surface area of any of the exotic materials and shapes used for aerospace re-entry systems, and paradoxically the fact that it enters the atmosphere at higher speeds and transitions to terminal velocity faster than spacecraft means that it has more insulation and a bow shockwave and plasma bubble happening, more material mass being removed per velocity/mass to carry away heat - as well as less time for atmospheric friction and heating to transfer to the core of the meteor.

I have no idea what size or mass of meteorite you would have to have for it to still be heating up on the surface by the time it reached the ground, but it would have to be catastrophically large.

Somewhere between the size of "reaches terminal velocity then falls out of the sky" and "So large it hits the ground at hypersonic speeds still producing plasma and causing an impact event" there's a wide middle ground of meteor sizes and velocities that mean "causes a minor to major bolide explosion and airburst event when it reaches thicker atmosphere, then rains down smaller parts and dust at terminal velocity" and even then parts of a bolide will likely be still cold after contact with the ground, because all of the heat got carried away in the ablative action and/or bolide airburst.

By the way - our atmosphere is basically constantly raining meteor dust. I can't remember the estimate but it's some impressively large number of tons per day or something like that.

You can try to collect it by placing a rare earth magnet, ideally somewhere high up like a roof and in the clear away from trees or blowing dust and leaving it alone for a while. Eventually it will start picking up dust and grains of ferromagnetic iron and iron alloys FROM SPAAAACE and this is a fun experiment to do with kids.

Some major percentage of it will be terrestrial airborne dust or mineral dust from rain, and some other major portion of it will be terrestrial magnetite, some percentage of it will be meteor dust either already landed and airborne - and then some smaller percentage will eventually be direct or nearly direct fall from space.

Another way to hunt for fresh meteorites is to go look for them in fresh or untrod snow and use a metal detector - or put together a strong magnet on a stick and sort of sweep the surface of a large snow field or probe the magnet into fresh holes in the snow.

If you find anything in/on top of the fresh snow bigger than about the pea to pebble size range it has a better than average chance to be a meteorite compared to rocks found on the ground because it's generally too big to be blown up in the air as dust or sand or terrestrial magnetite or iron ore.

There were scientists and meteor hunters and collectors that used this technique to find fragments of the Chelyabinks superbolide event since the region was well covered in snow in many places.
