Negative on that because you can't hide even if you want to.
If there is an aggressive species out there hell-bent on wiping out potential rivals, they will build super-thin telescope mirrors with the diameter of planets. With such telescopes, they could image any planet in the galaxy.

No, Brian. I pointed out the fallacy of that in another thread recently so I'm not going to repeat the whole thing. The cosmic speed limit of the speed of light is NOT a deal breaker for interstellar travel. No technological civilization is "stuck" except by temporary lack of resources. Known physics is not a barrier.
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
