No one has a monopoly on the sky. Amateur astronomers track active satellite missions, discover asteroids, mine public sky survey data to analyze stars, etc, etc. If there was anything out of the ordinary on the visible spectrum regularly showing up in our solar system (especially if it involved a lot of beelining towards Earth), it couldn't be hidden.
- nomel 3y agoThis simply isn't true, when whole asteroids sneak up on us: https://www.livescience.com/surprise-asteroid-flyby#:~:text=Scientists%20were%20unaware%20of%20the,closest%20point%2C%20according%20to%20CNET https://www.livescience.com/surprise-asteroid-flyby#:~:text=.... > rest of the billions of miles of our solar system Which we have to send satellites out to see, which image minuscule windows of space. Here are some of the very best pictures from ground based telescopes: https://phys.org/news/2017-07-ground-based-images-planets-pic-net-pro-am.html https://phys.org/news/2017-07-ground-based-images-planets-pi... Entire continents of Earth would be missed with that sort of resolution. And, with the need to average over time, whatever massive structure would have to stay relatively still. Most detection of distance objects is through occlusion of stars, not direct sensing. Good luck trying to find something something smaller moving at high/relativistic speeds, which would be a fairly reasonable requirement for not having to plan ahead for a multi thousands of years space trip. I don't really believe that space ships are flying around in our solar system, but I don't think us not seeing them, with our limited sensing, acts as any sort of counter evidence.
