only speculation
The above assumptions lead to the following conclusions:
1) ET artifacts are in the Solar System but we have not yet found them.
2) We are the first technological civilization in the galaxy.
3) We are the only technological civilization in the galaxy.
4) All technological civilizations have an intrinsic limit to growth that is significantly less than 100,000 lightyears.
My first guess is that 1) is true. I find it hard to believe that another technological civilization could not have developed in our galaxy prior to 10 million years in the past.
- Shouldn't 1) read ".. are in the Galaxy"? Narrowing it down to the Solar System is taking a very big bet .. I remember you discussing ET artifacts in the solar system in previous threads, but thought you were just speculating. Here you've pretty much committed yourself to the idea..
"2001" is my favorite scifi film (surely yours too ..) but given the size & location of the solar system compared to the whole galaxy, committing yourself to 1) is going too far into wishful thinking.
I would read any previous posts of yours on this idea if you can dig up the links ..
