Scientists Think Big Impact Caused Two-Faced Mars

physorg.com — Why is Mars two-faced? Scientists say fresh evidence supports the theory that a monster impact punched the red planet, leaving behind perhaps the largest gash on any heavenly body in the solar system.

  • yowhat2002, on 06/26/2008, -1/+24Mars has always been two faced. He's so nice to me when i see him, but as soon as i go away he's all "I hate that guy"

    Well ***** you Mars!
  • LeadStripes, on 06/26/2008, -2/+13Cheese has a natural tendency to form spheres. That's why.
  • Murdats, on 06/26/2008, -0/+11and if you dont understand those explanations.

    because god made it round and gravity is 'just a theory'
  • Mercedes383, on 06/26/2008, -1/+8I beg to differ that it has the largest gash. Paris Hilton has the largest gash in recorded history.
  • Advocate, on 06/26/2008, -0/+2anyone else get this ad in the article?
    *cough*

  • MovieQuest, on 06/26/2008, -0/+2If Mars was ever alive, I'm liking that these investigations are a huge intergalactic murder mystery: working backwards to solve the crime, Who Killed Mars? Sooner or later the culprit will be determined.
  • edalytical, on 06/26/2008, -0/+2As it goes a Mars sized object hit Earth and a Pluto sized object hit Mars.
  • j2p2f2, on 06/26/2008, -0/+1No Harvey Dent references?
  • inactive, on 06/26/2008, -0/+1Then why is the moon so round?
  • grubworth, on 06/26/2008, -0/+1Mars got into a fight with a monster that punched Mars because Mars is a two-faced bitch.
  • nkstn, on 06/26/2008, -0/+1i kinda felt bad after i got the joke lol
  • S1c0, on 06/26/2008, -1/+2I like this moon / crater combo. Deathstar!

  • supermanred, on 06/28/2008, -0/+1The Earth was hotter then, and the rubble collided with itself, forming bigger and bigger chunks until the "moon" had enough gravity to form into a sphere. Anything in our universe that has a strong gravity field forms into a sphere.

    The sphere is the resultant shape. Stars, plantes are all spherical as the gravity is strongest at the centre and keeps everything in a spherical shape.
  • DuffyDirect, on 06/26/2008, -0/+1Why does it have to be a meteor impact basin? Couldn't the thinner, smoother crust be perhaps a former ocean basin? Isn't ocean crust thinner on Earth??? On google mars it even looks like river-delta-looking erosion "drains" into the smooth basin like tributaries.
  • digifuzz, on 06/26/2008, -0/+1It was Jupiter with the candlestick in the kitchen!
  • choppa1890, on 06/26/2008, -0/+1For a second i thought this was a satire about Harvey Two-Faced beginning. :(
  • LokiAvenger, on 06/26/2008, -3/+3After impact the gravity between the parts that hadn't been added to the earth starting massing up a moon. gravity is the reason most of our heavenly bodies are so round.
  • minigig, on 06/26/2008, -2/+2the is very well know already.
  • fx666, on 06/26/2008, -2/+2Too many theories with no experimental data to support them.
  • snoogit, on 06/26/2008, -1/+1S/2004 S 6 represent fool!
  • JMellissa, on 06/26/2008, -3/+2Gee, I thought that some scientists theorized that a large object hit Mars and knocked off enough stuff to form the earth's moon. ... or was it the earth that got hit?
  • jcsoc, on 06/26/2008, -3/+2pics or it didn't happen
