"In astronomy and astrobiology, the circumstellar habitable zone (CHZ), or simply the habitable zone, is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure.[1][2] The bounds of the CHZ are based on Earth's position in the Solar System and the amount of radiant energy it receives from the Sun. Due to the importance of liquid water to Earth's biosphere, the nature of the CHZ and the objects within it may be instrumental in determining the scope and distribution of Earth-like extraterrestrial life and intelligence." -- Haven't read through it all yet, but wondering what Earth's habital zones are. For humans and then for any visible species and then any life at all. So 3 different scenarios. Someone said habitable zone for for Earth is within 5% of its current average distance. Not even sure if that means humans or any life at all. With no info at all, I would think Earth could be as close as Mars and as far as Venus (at their farthest and closest) for some life like bacteria to survive. But maybe I'm totally wrong and you really need to be in the right spot. Or maybe we don't know. #astronomy #interesting #science #%wiki #pub

I suggest a different, even darker solution to the Paradox. Basically, I think the aliens don’t blow themselves up; they just get addicted to computer games. They forget to send radio signals or colonize space because they’re too busy with runaway consumerism and virtual-reality narcissism. They don’t need Sentinels to enslave them in a Matrix; they do it to themselves, just as we are doing today. Once they turn inwards to chase their shiny pennies of pleasure, they lose the cosmic plot. They become like a self-stimulating rat, pressing a bar to deliver electricity to its brain’s ventral tegmental area, which stimulates its nucleus accumbens to release dopamine, which feels…ever so good. #interesting #deep_thinking #science #astronomy #space #pub
