- Yes. And some of them were bogus. His physical theory--involving
- continents sliding around on the sea floor--was pretty much impossible.

- What's sad is that he died (1930) on an expedition in deep Greenland, and
- so there was no one to really push the theory afterward.

- Not quite. Wegener predicted movements about three orders of magnitude
- greater than they were. These were detectable--had they existed--in his
- day, and of course the result was a disaster for his theory.
