You cannot prove any of this yourself.  You can only base this off the printed findings of others.  Then you have to trust that this person was not lying, misinformed, or just barking up the wrong tree themselves. 

Sure that's why every amature weather balloon sent up without a fisheye lens camera comes back with a perfectly flat horizon, you're a massive faggot guy.

i can't believe there are people who still believe that the earth is flat.

 

Really funny or is it just a place for few spammer.

Some people today actually believe that Hitler died in a ditch in Berlin ...lol. Can you believe that.!!!!

Everyone knows he made it out with the rocket men.!! Lol. Nazi's,Nasa, Naszholes.!

If it would be true, unters like you would have been wiped out, nomad.

I have to admit, I find it very interesting, and a bit disturbing, how you can see cities from great distances, when science tells you that given enough distance, you shouldn't be able to see such cities, they would be under the horizon due to the curvature.  Yet, with my own eyes, I CAN see buildings, that science tells me, should be under the horizon and shouldn't be seen.

I would have never even questioned any of this, if it weren't for good ole NASA. 

Good job NASA, you had me as a kid, but, I see your fake strings and CGI screens.  I'm all growns up now and see your trickery.  If you can dupe us on this, boy oh boy, imagine what else we could be duped on...
