That is the rub, isn't it? Short term predictions vs. long term. Very short term, we can predict things half way for solar activity since NASA
established true 360 degree visibility of the Sun (a recent first time capability). Though, that's still limited as it only covers what has already
formed on the opposite side and is coming around to face us. That sure puts a hard time limit on how far into the future predictions can be made, huh?
Long term...as you note so well, almost all of it has happened before and eventually, will happen again. Quakes, Yellowstone, a certain mountainside
in the Atlantic that'll slide into the sea someday and make a Tidal wave the Space Station should enjoy the view for. lol.... The thing that keeps me
from losing sleep is that "will happen again" is running down a timeline already 4 billion years old...give or take. The odds in my lifetime are
nil on any individual "mega-disaster" happening, I'd say.
Now I would note one thing that might be a little comforting
in terms of one problem you bring up. That is a low reflective object coming from
the direction of the Sun and the difficulties in seeing it. With the Satellites out now, as I understand it, we have one a considerable distance in
front of Earth's orbital position and another considerably out behind our orbital position, keeping distance/pace with us as we go. So we have
side-view ability to see something that would be hard to see from our perspective. Although, of course, even there. What would it buy everyone? A few
days or weeks to mark the days for confirming impact? I'm not SURE I'd want to know...
There is also the way they name these things in space and that should give everyone a bit of a start to look at a catalog list recently. The date, for
anyone not familiar, is when it was first discovered....as in, it was 100% and totally unknown to have existed prior to that. Now, check out how many
are 2010/2011/2012 dated/named.
On one hand...Oh we're so good at finding them. On the other...OH MY there are SO MANY and passing by all the time, like dumping a trash bin into a
wind tunnel. It's amazing we aren't hit hard more often.
