it’s easy to think of the solar system as kinda tidy with the planets roughly evenly spaced out but there’s a loving shitload of nothing even in such a relatively busy place eg mars is roughly 100 million kms away, which is kinda far in itself, but jupiter, the next planet, is another 600million kms beyond that, then saturn is another 700 million kms further on, another 1.5 billion kms to uranus and so on space is loving huge and between the literally astronomical distances and time dilation due to relativity there’s sweet FA chance of us ever making it very far out there. lmao

i think sagan or drake or somewhere calculated that if you run the drake equation through with reasonable assumptions, then intelligent civilisations would be spread across the universe at an average distance of about 200 light years apart. 200 light years is not far on a universal scale but is really quite a long way indeed for widdle humans drat you spacetime

i was thinking about how loving weird it is that space is a vaccum or whatever. like the idea of there being literally nothing in a physical space is kinda counterintuitive “some jerk” posted:The average density of the universe, according to NASA, is 5.9 protons (a positively charged subatomic particle) per cubic meter If you then think about the density of somewhere like earth: - 1 litre of water contains 1.10 × 10^26 atoms - 1 cubic metre is 1000 litres - a hydrogen atom is 1 electron, 1 proton. oxygen is 6 electrons, 6 protons (h2o) And that’s just earth. Obviously there are stars, planets, and all sorts of other stuff with high densities. with so much mass tied up in celestial bodies then space is even emptier than the average suggests. https://map.gsfc.nasa.gov/universe/uni_matter.html get it together ‘space’ u fucker git apologist fucked around with this message at 09:42 on Mar 19, 2024 |
