  • Intergalactic Social Blunder

    also called the "Human Race" by most.

  • so, have we figured out the 'shape' of the universe or not?.. if every 'point' is the 'center' and is moving away from 'everything', then why would galaxys collide?..

  • @Muaguana Nasa is your authority? Never a Straight Answer???? ROFLMFAO! Yeah sure dude and Pigs have wings and can fly!!!!!!!!!

  • I wrote you personal email since I can not defend against you lame attacks in this small box

  • @77GSlinger Look up the GP-B experiment that NASA performed, which supports Einstein's theory of relativity. And you know what the theory of relativity implies? That space-time can be distorted ("warped") by gravity. So nothing Sagan has said is outside the bounds of conventional scientific discourse, and based on your argument from ignorance I think it's safe to say you haven't a clue what you're talking about.

  • also there is snarf !!!

  • I can't fap to this.

  • @Gpsjoe2607 Extremely! And, I can back it up with facts!

  • @77GSlinger Please tell me your not serious?!!

  • @MrBR420 Ratings = Money, more people cut the cord every day.
