  • life is like a bright colorful candlelight in the dark.... :)

  • Tycho Brahe did not accept that the earth goes around the sun, not because he did not knew enough but because he knew too much. He measured parallax, which is the same when we close one eye than the other, when we do that the view changes. He did not observe this effect, because no one knew that time the stars are very very far. Tycho Brahe's equipments were not fine enough to show the parallax effect. There is a nice size crater on the moon named after the great Tycho Brahe.

  • There is - I wish I were joking - a scientology ad on top of the suggestions list.

    Sigh...

  • this man's emphasis on his words is SLIGHTLY disconcerting

  • We've got a new janitor called Keplar, he's really good, he sweeps out the same area each night.

  • @SSJKenshin I'm sorry to be the one to tell you that, yes, at the far end of the creationist spectrum there are people who insist on the geocentric model. In some ways it is less scientifically stupid than believing the Earth is 6000 years old, but it is still very stupid. Even more tragically, there are still Muslims and Christians who insist the Earth is flat. Go figure.

  • @USERNAMEfieldempty what? certain religions believed that a couple hundred years ago.. i dont think anyone still believes that, do they?

  • I daren't read this message thread.... cos I'll bet that there's some moronic religio-conspiracy freak claiming the Earth is 'in fact' at the centre of the system and spouting pseudo-woo-woo to 'prove' it. And that would wreck my 'feel good' mood that Sagan gives me everytime.

    Science for the win!

  • wasn't tycho murdered by mercury aren't you using his dna kike rasPutin? in this to be or not to be.

  • I need to mark 0:38 and 6:38 and 7:36
