  • Red is light at the 480 THz range. Blue is light at the 670 THz range. I think that’s perfectly described using terms of the physical world. If you’re talking about “what we experience as color” as being difficult to describe in our consciousness, then sure but that’s the case for every single thing we experience. Same way I can describe the musical note A as 440 Hz. Does an A to you sound the same to me? My tongue is sensing a sugar molecule, does the experience of tasting it feel the same to you?

    Not a single human perception can be described in words, but we can all compare perceptions to other perceptions and agree on the same answer. Perceptions are simply us recognizing patterns in our environment. Red is me recognizing my eyeball is looking at an object reflecting light in the 480 THz range. You look at that red ball and you also recognize it as reflecting light at 480 THz. Does it need to be described any further?


  • I don’t believe there’s much of a track record for private crafts reentering from orbit, intending to be recovered. Most private crafts like communication satellites breakup on reentry and don’t pose much of a risk to ground population. This station was designed specifically to survive reentry intact. I’m not sure what kind of deorbit equipment that station has but I would guess that’s what the FAA is concerned with. Any failure of navigation or propulsion during deorbit could result in the station losing control which would have it crashing down in some unpredictable point and time along its 25,000 mile path over ground. Undoubtedly there are some large populations below the orbit of this station
