As a non-astronomer, I hadn't thought of that but now that I read the abstract, it makes complete sense (assuming evidence supports the thesis)
- Might be related to why moon's surface is so scarred and yet in many centuries of recorded (astronomical) history (since the invention of telescope) we haven't seen any major lunar impact events.
- Also I was reading the other day how our solar system is going through a local "bubble" (region of unusually low interstellar density) but is heading towards a certain G-Cloud.
Mind blowing stuff. I guess once we have fixed the planetary mess (climate change) and biological-aging, we'd have a serious type-I [2] problem to worry about (and we can't even handle/track the inner solar system objects yet, NEO, asteroids, etc).
