  • We could, but it’s way more expensive. There was a ~10m dish added to space VLBI, but the ground stations are several times larger, up to a few 100m. And you need dish size for sensitivity: in interferometry the largest distance between two telescopes gives the size of the synthetic instrument, but the size of the individual dishes fills up the detector.

    Also, if something breaks it’s almost impossible to fix in space.



  • There was a related podcast recently somewhere, the idea was that evolutionary lungs come from guts, so maybe guts would still have some ability to absorb oxygen, which, turns out, they indeed do. This could have some practical uses e.g. in intensive care situations where the patient’s lung is useless (extreme COVID), which could give a last resort breathing opportunity while the lungs heal to a usable condition. Furthermore it gives a shitton of opportunity for butt jokes
