…Namely, the remains of exploded planets in the solar system. So says rogue astronomer Tom Van Flandern and it seems like every new finding supports his theory, yet he still gets no respect from the establishment. Hm. Like these bits about how comets and asteroids are so similar in some cases that, well, Van Flandern’s assertion that they are the same thing seems like what you might call reasonable.
Van Flandern’s idea is essentially that asteroids and comets are each rocky bodies with some water. Most asteroids have had their water burned away already since they hang out in (relatively) close orbits around the sun. Comets, whose orbits take them farther away for much of the time, haven’t burned off all their water yet. But they are otherwise essentially the same, and it is no surprise to see objects that blur the distinctions between them (unless you are a mainstream astronomer and think the exploded planet hypothesis is ‘wacky’, no matter how many predictions it racks up).
