  • A pity they burned down the library and humanity had to wait hundreds of years to "rediscover" the size and spherical shape of Earth

  • Unforgivable tragedy would be more accurate.

  • We could have had all diseases cured and spaced colonized by now. Thanks, religion.

  • @Vildasnaga fucking Christians.

  • WHY IS THIS MAN SUCH A BOSS!?

  • @meloveoasis Awww. I thought miles. I was using miles. I uesed to tell my gf I wish I was 28,411 miles form here whenever we were snuggling. See? I would be right where I was when I said that.

  • @Tryoutz747 That sound more like the radius or in some measurement other then Km. It's circumference is 40,075. 16 Km.

  • @islamisnuts Correction, Agent Smith sounds like Carl Sagan--i believe Hugo Weaving did base it on him

  • it is 28,411 not 40,000. he was off 12,000.

  • Close your eyes and Carl Sagan sounds like Agent Smith from the Matrix.

  • Some 3,000 years before Eratosthenes was born, people inhabiting a small western Island built what is known today as Newgrange. It's the oldest still standing man made structure on this planet ... Just imagine that 5,000 years ago people had measure of understanding of what we now refer to as our Universe. It seems that the more access we have to information and knowledge..the less we seem to use it.
