Today, some real history.
A while back, when Morlock Publishing’s Twitter feed was public, he retweeted a fascinating quote from someone’s book.
“The meteorite itself was so massive that it didn’t notice any atmosphere whatsoever,” said Rebolledo. “It was traveling 20 to 40 kilometers per second, 10 kilometers — probably 14 kilometers — wide, pushing the atmosphere and building such incredible pressure that the ocean in front of it just went away.”
These numbers are precise without usefully conveying the scale of the calamity. What they mean is that a rock larger than Mount Everest hit planet Earth traveling twenty times faster than a bullet. This is so fast that it would have traversed the distance from the cruising altitude of a 747 to the ground in 0.3 seconds. The asteroid itself was so large that, even at the moment of impact, the top of it might have still towered more than a mile above the cruising altitude of a 747. In its nearly instantaneous descent, it compressed the air below it so violently that it briefly became several times hotter than the surface of the sun.
That someone turned out to Peter Brannen, and his book is The Ends of the World: Volcanic Apocalypses, Lethal Oceans, and Our Quest to Understand Earth’s Past Mass Extinctions (affiliate link).
Here’s a talk at Google from 2017. He does go off into climate change about 25 minutes in, so you could maybe punch out when you’ve had enough. I think his discussion of things like Chicxulub make this worth it. (I was actually not aware that there was a controversy over whether that killed the dinosaurs: I thought the science was settled.)
Bonus: since the Ides of March have just passed, how about an episode of “Ancient Rome: The Rise and Fall Of An Empire” on Caesar?
Bonus #2: while I guess this is semi-thematically appropriate for St. Patrick’s Day, I’m bookmarking this here because of my interest in crime, law, and prison breaks.
“Unlocking the Maze”, about the escape of 38 IRA prisoners from the maximum security Long Kesh prison on September 25, 1983. Again, I am not making a political statement here: I just find prison breaks fascinating.
