I watched a show on TV about the Oort cloud, that featured a visual. I think it mentioned something like several trillions with a t objects surrounding the Sun outside the solar system. And the image showed just that, a cloud so dense and thick you couldn't see the sun. Combine that with all the millions of pieces of space junk circling the earth, how in the world can any serious astronomy occur? How do we know the light (of any type) isn't being affected by all these objects, especially the ones in the oort cloud, even indirectly? When we're talking about such minute things as shifts in a sun's orbit indicating existence of planets, I don't know, it just seems to go beyond belief.
