I wish more people were aware that we are likely the only radio-using sapients in a 4'ish light year sphere around us [1] (4.4 ly for a 1MW broadcast, where the most powerful radio transmitter in the world is at 2MW). And that we're roughly in the center of the KBC Void [2], about a billion light years from the nearest "normal" baryonic density of the currently-known universe.
We might not be alone inside the KBC Void, but if we aren't, they and us are on a pretty isolated island of sapients in the currently-known universe.
Sapience is astronomically, vanishingly rare as far as we can tell so far. Some of us treasure it and are thankful for it accordingly. Perceiving reality at the level we do, with the understanding we only scratched an atom of the total surface so far, is both inspiring and humbling at the same time.

- LocalH 5y agoMy current personal belief is that the universe is currently rife with life on a number of planets, but they're all so far apart that they might as well be the only ones from the perspective of each planet. I feel that it's highly arrogant of humans to presume that "there is no other life in the entire universe, except for Earth".
