I dunno. Maybe I had heard it as a proposed idea some time ago and took it as writ. Or maybe I intuited it on my own not realizing that wasn't accepted theory. Or misremembered. All I know is that when I read that press release I was thinking "Yeah? What's so novel about that? I thought that's the way it worked anyway."
Regarding mountains, disregarding all other forces I can see how there would be a tendency for the weight to want to crush the mountain over time, a looooong time. But it seems to me other forces would overwhelm this process, particularly the forces pushing the mountain upward. Yes, gravity makes things that go up want to come down, but that 5 million pounds of thrust rocket engine just isn't going to let that happen. I wonder if there's any old mountain ranges that have spread out that I can spot in Google Earth.
As for the normal faulting, I thought that was caused by the compressional uplifting of the range, not any relaxing spreading.
Hmmmm.... maybe I need to go back to school?
