Back in the dawn of the uncrewed space probe era, one reaction to the new model solar system was to compile "farewell" anthologies to the golden age worlds now displaced by new facts. I own FAREWELL, FANTASTIC VENUS and JUPITER but I was sure that there was one for Mars as well. Does anyone remember the title?

Date: 2006-07-09 07:28 pm (UTC)You'd think the amount of energy used to disrupt an Earth-sized planet (roughly all of the energy the Sun emits over a week) would have killed Explodie the Fifth Planet stories ages ago but I read one just a couple of years ago. OK, it _was_ a Hogan but I am pretty sure Robert Sawyer used the idea as well in END OF AN ERA.
Now, do I want to google "Tom van Flandern" and "science fiction" or would it just make me sad?
It seems to me that one of the old serials used to pad out the 1970s translations of Perry Rhodan had to do with the asteroid belt.

Date: 2006-07-16 02:02 am (UTC)I recall getting into heated exchanges with him on usenet. His idea about the source of the asteroids in a recently disrupted planet was just crackpot. An Earth-sized planet with chondritic abundances of elements would have an extremely hot interior, just as the Earth does, and for the same reason (radioactive decay). The core of the Earth is as hot as the surface of the Sun, and is kept in a liquid and/or solid state only by the enormous pressure. If you break the Earth into small pieces, decreasing that pressure, you don't get chunks of iron, you get a fiercely glowing cloud of iron vapor. Most of the mantle would also melt. The result would look nothing like the asteroid belt and meteorites we see today.
