At least according to scientists, whom I never question. Even when they insist that canals exist on Mars, draining blood can cure illnesses or that a walk is as good as a hit. If they weren't smarter than me, they wouldn't be allowed to wear those white jackets, right?
Anyway, a couple of astronomers (which I'm told are different from astrologers) published a paper this week in the Proceedings of the National Academy of Sciences. It's one of several magazines to which I subscribe, arriving Tuesday along with Grit and Cracked and a few days before The Saturday Evening Post. The astronomers say that our inner solar system once had a bunch of what they call "super-Earths." Those are planets larger than ours, but not as big as Neptune.
(Neptune is really big. When it sits around the sun, it really sits around the sun! When Neptune steps on the planetary scale, the scale says "one at a time please!" Am I right? Neptune is big!)
The point of the article was that at some point in ancient history (probably before the American Revolution and maybe before the invention of the fork) Jupiter bulldozed in and smashed those "super-Earth" planets into the sun, which laid the foundation for the creation of the Earth and other smaller planets . . . wait . . .
Did they really say creation of the Earth? Scientists said that?
Nevermind. I don't want to get sidetracked. But the Earth was created? Hmm.
Anyway, the idea is that Jupiter pushed toward the sun, smashed those would-be planets into the sun, then returned to its normal rotation – presumably with its hands in its pockets, whistling and hoping that nobody noticed.
The best parallel – and I'm sure you're already thinking this – is roller derby.
Jupiter played the role of the "jammer," who smashes skaters out of the way so that the "pivot" can skate ahead and score points. In this case (to use a 50-year-old metaphor), Jupiter was Charlie O'Connell and the Earth was Joanie Weston, both of the Bay Area Bombers.
Got it? Much easier to understand now, right?
Another interesting part of the theory, which is known as the Grand Tack scenario (because the "Gran Torino scenario" involves a racist character played by Clint Eastwood), is that Neptune was drawn toward the sun because of its huge mass. The only thing that stopped it was Saturn, which entered a "planetary dance" with it due to both planets' large mass, a dance that sent both farther into the solar system.
That's ironic, because I owned a Saturn for several years and find it unlikely it could travel anywhere without some sort of maintenance. Although perhaps the "planetary dance" would have been a better excuse for when my side-view mirror came off than the truth: I backed into the side of the garage.
But enough of that. Why do you keep side-tracking me?
My point is that Jupiter should be appreciated. After all, most of us have some love for Mars (great candy bar!), Pluto (cute dog, even if it's not a "planet" anymore), Venus (cool songs, one version by Frankie Avalon and another by Shocking Blue and Bananarama) and even Saturn (affordable car, even though the side-view mirrors seem defective).
Jupiter? Other than an occasional song mention (which prompts my first-ever mention of San Francisco-based band Train), it doesn't get much love.
But Jupiter made it possible for Earth to be created, according to scientists. Three cheers for Jupiter!
And roller derby, which made this science lesson understandable.
