I'll try and dig one up for you! Also, think about how night and day would work on a flat Earth. Or the electromagnetic shielding of the Earth. Gravity has already been mentioned. I realise i'm not providing you with any evidence, just things to think about.
Perhaps one day Steemians can fund an experiment to prove once and for all that the Earth is a globe and that there is no edge. Might be fun!
That sounds like a great Steemit project in the making! Send a Steemit satellite up into space and record the whole journey till we can see the earth as a globe from a distance? Might need a bit of funding however :)
Lol when 1 steem is worth a million dollars, i think we'll be able to afford it. So we should be able to fire her up some time next year then?! ;)
