  • Obligatory HHGTTG quote:

    In fact there was only one species on the planet more intelligent than dolphins, and they spent a lot of their time in behavioural research laboratories running around inside wheels and conducting frighteningly elegant and subtle experiments on man. The fact that once again man completely misinterpreted this relationship was entirely according to these creatures’ plans.












  • The crazy part is that your brain is doing similar processing all the time too. Ever heard of the blindspot? Your brain has literally zero data there but uses “content-aware fill” to hide it from you. Or the fact, that your eyes are constantly scanning across objects and your brain is merging them into a panorama on the fly because only a small part of your field of vision has high enough fidelity. It will also create fake “frames” (look up stopped-clock illusion) for the time your eyes are moving where you should see a blur instead. There’s more stuff like this, a lot of it manifests itself in various optical illusions. So not even our own eyes capture the “truth”. And then of course the (in)accuracy of memory when trying to recall what we’ve seen, that’s an entirely different can of worms.


  • My understanding is that’s exactly the point. To make clocks on the Moon be synchronized with UTC and not drift over time. You can only do that by making the clocks physically tick at different rate. This is because of relativity - time itself on the Moon passes at slightly different rate than on Earth, so if your clock is precise enough, you need to compensate for it. Just like GPS satellites need to compensate for being in slightly lower gravity and going fast relative to stationary clocks on Earth’s surface. This isn’t any kind of illusion, this is how the universe really works. If you’ve seen the movie Interstellar, it’s basically the same effect they experienced on the planet orbiting a black hole, just a much less extreme case.
