I know I’m a few years behind, but I just checked out a copy of LONELY PLANETS: The Natural Philosophy of Alien Life (2003) by David Grinspoon. He does, of course, have a “doctor” in front of his name, but it appears that he doesn’t use it very often. He also has the endorsement of Neil deGrasse Tyson – the quintessential new face of astronomy and the immediate successor to Carl Sagan.
Tyson said of Grinspoon’s book “…brings together what has never before been synthesized…he is a planetary scientist as well as dreamer, born of the space age.”
As is apparent to anyone who reads my blog, I LOVE aliens! I write about aliens! I do (guardedly) believe that there is intelligent life “out there, somewhere” – HOWEVER, I don’t believe that we have any real proof yet and that it is, at this point, an intellectual and philosophical exercise.
Be that as it may, I’ve only read the first 20 or so pages of Grinspoon’s book and skimmed his website (http://funkyscience.net/), but I find myself looking forward to following this guy for some time to come!
I’m a bit over halfway through the book now (page 198) and I’ve placed an order for my own copy through a Half-Price Books near me. I’m even (*gasp*) dog-earing my Library copy for later transfer to the book when I get it.
Couple of things I noticed thus far: the book is old. Published in 2003, it was most likely written in 2002. This was substantially BEFORE the Kepler Telescope was launched into an Earth-trailing heliocentric orbit in 2009. Six years later, Kepler celebrated the discovery of its 1000th confirmed exoplanet. Another three years followed Kepler sweeping more and more prizes into its discovery bin. Then “On October 30, 2018, after the spacecraft ran out of fuel, NASA announced that the telescope would be retired. The telescope was shut down the same day, bringing an end to its nine-year service. Kepler observed 530,506 stars and discovered 2,662 exoplanets over its lifetime…” (Anyone else hear a faint echo of “…its five year mission, to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no [one] has gone before!”?)
Despite the age of the book and now that I’ve read half of its 416 pages, I’m puzzled by Grinspoon’s not mentioning “hot Jupiters”. With statements like: “In the hot regions near the Sun, it snowed flakes of metal and rock. Farther out, around the present orbit of Jupiter, it was cold enough for ices to form: both the familiar snowflakes of water ice that adorn winter on Earth and more exotic snow of frozen methane and ammonia.” (page 82); and “The initial segregation of material by temperature, which made metal and rock near the Sun, and ice farther out, has been preserved.” (page 83).
Why is that? He DOES mention the discovery that the star 51 Pegasi had a planetary companion. That happened in 1995 (embarrassingly, this story doesn’t start until page 209 and as I mentioned, I’ve only just today reached page 198!). After this account, Grinspoon goes on to marvel at the discovery of some hundreds of extrasolar planets (!), having only a faint idea that Kepler would soon blow that number out of the water.
My other trouble is that when discussing Venus, he makes virtually no mention of the fact that it has a retrograde rotation when compared to the rest of the planets (I don’t count Uranus among those having a retrograde rotation. That gas giant’s rotation is retrograde only because its “north” pole is actually south of its “equator” (the Solar Equator, if you will. That is, the planets and minor planets orbit the Sun orbit in the same direction on pretty much the same plane. Confused? OK, this is how I explain it to my astronomy classes. Imagine your head is the Sun. If you stick your arms out and start to torn slowly in (ignoring the direction at this time) and stuck ball bearings of increasing sizes on your arms with duct tape at increasing distances from your head, you would have a basic illustration of the Solar System as it turns in space. Imagine then, that each of the ball bearings are turning the same direction: except for Venus. It rotates in the opposite direction of everyone else – and it turns VERY, VERY slowly. When you reach Uranus, let it keep spinning in the same direction, but tip its north pole 98 degrees (90 degrees is like a “90 degree angle” or as you may remember from geometry or trigonometry, a “right angle”.) Uranus is tipped MORE than that…but it’s still rotating the same direction as it did when it was upright…but now it’s spin, relative to the other planets, is backwards (aka “retrograde”).
At any rate, Dr. Grinspoon talks about what it is that has created Venus’ hellish conditions and while he does include its location (closer to the Sun than Earth), the fact that the Sun is brighter and hotter today than it was when the Solar system formed), and a peculiar venology (it can’t be “geology” and “aphrodology” just sounds weird…) that includes a sort of cyclical disruptive plate tectonics (pages 171-173); he doesn’t mention the slow, retrograde rotation. By slow, I mean that a “day” on Venus is 243 Earth days; and the Sun would rise in the west and set in the east…eventually.

It could be that I haven’t reached those pages yet, so we’ll see.
Perhaps the biggest “kick-in-the-teeth” is that he clearly lays out what happened to alter our Solar system longer ago than 65,000,000 years: “As the planets approached their final sizes, giant also-rans, the contenders that could have been planets, came hurtling down to Earth (and Mercury, Venus, etc.) at speeds of tens of thousands of miles per hour. These final giant impactors left a trail of destruction throughout the solar system, stripping Mercury of its outer rock mantle, leaving Venus spinning backward, and knocking Uranus on its side And in an event as propitious for us as it was random, a Mars-size protoplanet smacked into the young, still-forming Earth, splashing a massive ring of vaporized rock into Earth orbit, which quickly condensed to make out singular, giant Moon.” (page 82)
If any of you ever read the first book of my proposed series HEIRS OF THE SHATTERED SPHERES: Emerald of Earth (which might be serialized here https://stupefyingstories.blogspot.com/ starting in January or so…), I have a slightly more fantastic explanation for the current state of the Solar system. Emerald Marcillon’s mother, Nhia Okon, explains to a group of high-ranking military brass:
“The evidence we’ve gathered so far clearly indicates that a massive object, probably a microscopic black hole, grazed Uranus and tipped it on its side….A fleet of invading interstellar warships, using black-hole-energy technology probably experienced a disastrous explosion shortly thereafter. Debris swept through the solar system, probably missing Saturn but raining down on Jupiter and setting off the Great Red Spot hurricane…The worst was yet to happen…Mars had shallow oceans that teemed with microscopic life forms. A large rock, possibly an asteroid knocked from a stable orbit and carried on the shockwave of the explosion, slammed into the planet, blowing away much of its air allowing the oceans to boil away under low pressure…Another asteroid carried on the shockwave struck off the coast of what would one day be the Yucatan Peninsula. The dinosaurs and thousands of other life forms, already environmentally and genetically stressed, were launched into extinction…This is the world of an alien, probably sauroid intelligence native to the planet we now call Venus. They were aggressive and powerful. Spreading through our solar system, we have evidence that they conquered beyond it. The invasion fleet had come to put a stop to it….But the accident that destroyed the fleet and saved the sauroids from certain invasion, next threatened them with the mindless destruction of chance…An object nearly large enough to split Venus in half hit the sauroid moon, knocking it cleanly out of Venus’ orbit, where it drifted until the sun captured it again, the molten scar on its surface glowing red hot for nearly a century. The world we call Venus was pounded by meteorites sleeting through the vacuum of space. A second monstrous object was large enough to reverse Venus’ rotation…The solar system had been reshaped and the intelligences on the new, second planet of the shattered star system were extinct. We are the heirs of those shattered spheres. We are the ones who must piece together the details. We are the ones who must find the bits of technology that we can use to go to the stars...”
I’ll leave you with this, and I’ll continue next time, hopefully I’ll have finished the book!
