  • I was just noticing how this clip has a total viewing of not even a mere 16,000 (and many of those is ME going to it a million times)??? And crap like 50 cent and Harry Potter horseshit has a zillion...what's that say about the future...we're fucking doomed...

  • @28october19731 Trust me. That is the least of our worries. Rarely is what it is edifying also what is popular.

  • Hmmm... if one model could make accurate predictions and another could not then I would conclude that the former is more likely to be correct. A not (in my opinion) unreasonable conclusion for the average layman.

  • Yes, but those with long running observations according to the ptolemic method had noticed that it was becoming less accurate as time went on. Also in order to account for small oddities in the movement of the planets, mostly stemming from Ptolemy's explanation of retrograde motion, his system had grown complex and idiosyncratic.

  • another reason to hate the omish

  • @SanGuevara stupid...

  • It is possible that that actual universe may be as many time larger than the known universe as the known universe is than a subatomic particle or that much larger than that or it could be tetrations of magnetude larger. This would mean far more galaxies than there are atoms in the know universe. Based on the fact that we keep more objects the deeper we look the actual universe would on average be many times more densly packed than the known universe.

  • @SanGuevara Nature's plan:

    1. Run it's course.

  • i dream of a religion-free world

  • @benben42
