re: So did you not read or not get the link that explained why discoveries are such a small fraction of exspected infall?
So very little might reach the surface, not much more than we know about. I know they say all this material gets to Earth but it's all estimates and guesses. We don't really know any more than we can hold in our hands, and extrapolate a certain number of smaller ones from that. Studies like this, next month there might be another one that says different.
