The Earth's radius is often quoted when describing the size of exoplanets, such as those recently discovered by the Kepler telescope. Why? More astronomy and physics at http://www.sixtysymbols.com/

  • I live on a Styrofoam planet.

  • @Desmaad Sorry, I confused the two.

  • @Lavell1TheElite I hear that a lot. The  saying "energy is god" or "nature is god" well, why call it god at all? Just call it the universe, or call it Nature. Why is everyone so desperate to pin that label of god onto anything they can grasp at? Just let it go and know that the Universe is the location, and nature is the novelty machine that spews us out. That is certainly enough for me.

  • @SpacedTime I think the universe is god.. I mean it did create everything LoL

  • That's a pretty interesting calender in the back you have...

  • Have there been any planets found around Alpha (a.k.a. Proxima) Centauri?

  • @1DARBY1 you are damn right, my goodness I can't even work my shitty MP3 player right and look at this guy.

  • Sift the Twos and sift the Threes,

    The Sieve of Eratosthenes.

    When the multiples sublime,

    The numbers that remain are Prime.

  • @seaplaneguy1

    OMG DUDE YOU ARE ONTO SOMETHING HEAR

  • @LamaPaj Earth's radius was the original proposal for the meter, but because the French could not determine it (no orbital space ship in the early 1800's) the French decided to measure the 1/4 arc from the pole to the equator over the distance of France and guessing the rest as as the standard of the meter. That 1/4 arch divided by 10 million IS THE ORIGIN OF THE UNIT OF MEASURE KNOWN AS THE METER. Had they chosen the radius instead, the Inch and meter system would be the same.../25.
