  1. R2D2 can just plug in and get schematics and status, wherever he goes. Computer security, as I said earlier. Han and Luke do manual aiming on the Falcon when they escape the death star. Fighters have computer assist, but not tracking. Mentioned above.
  2. Computerized weapons tracking on certain space vehicles. e.g. the Millennium Falcon The tech we see is simplistic, e.g. on the x-wing and TIE fighters
  3. No, that’s not true. Possible but unlikely. The false positive rate is something like 1 in 25 years.
  4. Saltwater corrosion is a problem for your pipes and pumps. Runoff would be a problem. And I don’t know how refreshing it would be after spraying, with the salt residue on your skin.
  5. We don’t know for a fact that the GW event originated at Betelgeuse. It came from that direction.
  6. ! Moderator Note You added one sentence that says Betelgeuse is dimming. Not a paragraph. No substantive science to discuss. Insufficient to be a basis for discussion. Maybe you could focus on discussing the topic, instead of these off-topic sidelights.
  7. ! Moderator Note Dropbox is not YOUR noncommercial site, and you’ve ignored the part that says people have to be able to participate without clicking any links.
  8. ! Moderator Note Your posts got locked because you AREN’T posting the article and the relevant paragraph.

  10. If someone makes an argument based on the moon being made of cheese, I think people should call out the flawed premise rather than waste effort on the rest of the argument. YMMV
  11. ! Moderator Note You can re-introduce this if you comply with the rules (2.7 in particular)
  12. ! Moderator Note Please start following the rules. You can re-introduce this topic if you comply (specifically rule 2.7)
  13. Its maximum density is at about 4 C
  14. It may wobble less, but it wobbles. The direction of the north pole (rotational axis) is not fixed. https://en.wikipedia.org/wiki/Polar_motion
