Carl Sagan on Human Brain

sebevan asked:

For the first time in history, an Earth-like planet has been discovered orbiting a distant star. At only one and a half times the radius of Earth, Gliese 581 C is the third and smallest planet to be discovered orbiting a Red Dwarf star located 20.5 light years away in the constellation Libra and the first one to approach the Earth’s size. The planet resides in the star’s “Goldilocks Zone” where liquid water –and life could occur. The team of Swiss, French and Portuguese astronomers used the European Southern Observatory’s 3.6 m telescope to make this incredible discovery. See the video for more! AstroShorts.com

“Gliese 581 c or Gl 581 c is an extrasolar planet orbiting the red dwarf star Gliese 581. With a mass at least 5.36 times that of the Earth, it is classified as a super-Earth, a category which incorporates planets exceeding the mass of Earth but smaller than 10 Earth masses, it was the smallest known extrasolar planet around a main sequence star, but on April 21, 2009, another planet orbiting Gliese 581, Gliese 581 e, was announced with an approximate mass of 1.9 earth masses, which is now the smallest known extrasolar planet around a main sequence star.”

You can always ask “well then what happened before that?” The god hypothesis explains absolutely nothing; it gets us no closer to an answer. It’s just a continuation of the same infinitely regressing line of questions.
