    This reasoning is pretty weird, but the conclusion is basically right. That is, there is absolutely no way to extend the conventional notion of volume to Rinfinity, which is basically what most people would imagine is the infinite equivalent of our dimensional space. Edit: what I mean by Rinfinity is a bit ambiguous, but let’s say for the purpose of a hypersphere we want something like l^2 hilbert space to ensure no vectors with infinite length appear, then we have a separable space and the proof is complete.












  • This diagram is way way way too conservative with the “see you on the other side” classification. To name a few: fluorine will literally make you catch fire instantly (if there’s more of it, you will basically get burned to a crisp before you can even blink), caesium will violently react with water in your mouth and produce so much hydrogen and heat, the whole mixture will instantly explode (in fact, this will not only be a usual, fire-like explosion, it will in addition to that be a so-called Coulomb explosion, which makes the situation even worse)


  • Well, nothing is that simple, in fact one of the biggest problems in society is that each of us has their own biological clock, with preferred activity and sleep hours, yet we are forced to align our schedules to the same universal standard. Of course, it is absolutely vital for the way our current society functions (because we, as a society, work together, take classes together, commute together, socialise together, celebrate together, and so on), but it definitely has been hurting billions of people for the past thousands of years and we should look for a way to eliminate this system as soon as possible.
