Feels like a proper movie that political boundaries like state lines would be significant for all concerned. One meteor for Rhode Island, one for Texas... Any questions? (Asks the alien overlord of his minions in his crisp British accent)

The rest of the world, if they’re even mentioned in the plot, get one per country at most.

"230 tons of TNT" I hate units of TNT. Ill do psi. Love the foot. The calorie is metric! But what on planet earth is "ton of TNT"? The energy that was dissipated (using 0.5 mv^2) was 1TJ, or the 280 000 kWh.

Just to add to the confusion, that's metric tonnes, so it should be "tonnes" or "metric tons", but not "tons"

I think "tons of TNT" make sense for an explosion? At least it works for A-Bomb equivalents, in this case it was like, huh, ~1/50th of Little Boy.

The day was somewhat stormy. I was in my kitchen in my north-suburban-Boston house, when I suddenly heard a BOOM. I thought it was a very large branch falling on my house, so I ran outside to check out the roof. Saw nothing, and only later heard about the meteor.

A few years ago I heard a bang and my whole house shook. My roommate and I both thought a car had hit the house. Never did find out what caused it, I think it must have been a sonic boom, most likely a military aircraft. The way it shook the house though, it was hard to believe that something didn't hit the building.

That’s what a small earthquake with a nearby epicenter feels like. The first time it happened to me it felt like a tree hitting the house. (“Small” is circa 3.0 magnitude.)

Meh, a metric ton is 0.9 of a US ton, well within the error bars for this sort of thing.

Your statement is not supported by, and is somewhat at odds with, physics. As described in this source, observed terminal brightening/"burst" of a bolide is tied to the body's material behavior (fragmentation, rapid lateral expansion, ablation), and not to a free-standing "deceleration shockwave" that exists independently of the body breaking up. https://adsabs.harvard.edu/full/2001ESASP.495..491R

Some meteors really explode, because water and other volatile substances contained in them transform from solids into high temperature gases that expand quickly and cause the explosion of the body. This is the same like how many kinds of water containing things, e.g. raw meat, eggs, fruits, can explode in a microwave oven if the microwave power is too high. The meteor bodies belong to several classes of chemical comp…

You forgot the fact it will hit something! Craters are not made silently! https://en.wikipedia.org/wiki/Meteor_Crater#Formation

You're being excessively argumentative. I didn't state that the shockwave is independent of whether or not the body breaks up, I wrote, emphasised, "Expanding the diameter of that particle field will increase the size of the resultant shockwave, whether the particle separation itself is "explosive" or not." Which your article (partially read, sorry, incredibly shitty reader) largely substantiates, largely in the item…

You're defending idiocy. The PSA is false. There is science behind it. There is little nuance to salvage in any of it.

Apparently it fell into the water. Maybe it can be recovered and made into the second coolest rock exhibit in Massachusetts (first is Plymouth Rock obviously).

This time Malcolm X’s line about “Plymouth Rock landed on us” would apply to everyone. And Plymouth Rock is very much not cool. It’s the anticlimax of a million school field trips.

Plymouth Pebble.
