Sorry for exposing you nice people to this particularly nonsensical piece of pseudoscience, but I just want you all to know that I'm much sorrier for myself that I actually have to spend time working to denounce this crap. *** On another forum, I famously got into trouble with a guy who famously argued in favo(u)r of some idiotic piece of pseudoscientific crap called the "Growing Earth Theory", which famously argues against the idea of plate tectonics by famously positing the idea that the Earth was once much smaller in volume than it once was, and that the consequently lessened force of gravity upon the surface allowed the gigantism famously observed amongst the major fauna of the period (i.e., the Dinosaurs) famously known as the "Pangea" period. When I famously pointed out to him that gravitational attraction famously applies as the inverse square of the distance from the attracting body's center/centre of mass, which means that the Earth's gravitational pull on the surface would have been much GREATER had the Earth a smaller volume back then, he challenged me by famously asking me why I was so "hung up on that inverse square of the distance thing". At that point I cut off all contact with him. Anyways, their basic idea is that, seeing as all continents fit together if one excises all oceans from the globe, that what's really going on is that the earth was, just 350 mega-years ago, much smaller than it is. That the continents all fit together thus is, I believe, the result of there having been more than one supercontinents in the past, such as Pangea (q.v.) and the one before that, Rhodinia (q.v.). (I mean, don't these fact require conversion of the "Growing Earth Theory" into the "Oscillating Earth Volume Theory"?) The way I see it, contineltal collisions due to tectonic forces are a little like the funny auto insurance ad popular in the US right now, in which some guy tries to parallel park, and winds up going back and forth, crashing into the car in front of him as well as into the car behind him. Obviously, after a few such crashes, the front end of the car behind him is going to resemble his own rear end, just as the rear end of the car in front of him is going to resemble his own front end, according to simple observation which need give rise to no "Lengthening Street Theory".
