Sadly, what I hopes would be the final technical tweak turned out to be problematic. I want your account pages to display all your comments in a tab. This should be a simple task. There are clear directions for it. But they don’t work in my case (although they do in other, seemingly identical cases of tabs).
I really want to be a blogger. I am so done with being a site builder [snarl].
“The Moon’s Mysterious Origins Still Stump Astronomers” [Science Alert]:
A half century after NASA’s Apollo 17 lunar module lifted off the Moon’s northeastern near side quadrant, planetary scientists still don’t completely understand when or how our Moon first formed.
They do agree that it involved a major impactor – an object dubbed Theia by lunar scientists – that likely struck our Earth some 4.51 billion years ago.
But the estimated size of Theia now ranges from a proto-Mercury-sized object all the way up to an object that was about half the size of present-day Earth.
What would cause the Moon to be mostly made up of Earth type material?
To make the Moon in a classic giant impact, Theia needs to hit Earth with a sort of glancing blow, where half of Theia misses the Earth, says van Westrenen.
Half crashes into the side of the Earth while the other half sort of moves past and then goes into orbit around the proto-Earth which forms the Moon, he says.
But in this scenario, the Moon should be mostly made up of rocks from the Theia impactor. But that’s not what geologists see.
