I need to watch this show more like I used to. It keeps me sane to think about the universe rather than the absolute dumpster fire human civilization is in right now.

Finally. This is exactly what i expecting from a channel, person, newspaper whatsoever who says he is dedicated himself to science. No sensationalism, no mishmash but facts, rationalism and sober talk about possibilities. I really doubt there are anyone who interested in this subject would not be happy to find life. But without certainty its just simply not working. Its not how science works anyway.

This is one of the channels that I have never seen a bad show, or even an uninteresting show. Every time I see or hear Neil it's a treat, I know that may sound sickening, but it's true. As a matter of fact, I could say the same thing about David Kipping. Astrum and Cool Worlds. These guys can get your mind going. Thanks
