Dear Princess Celestia,
What if we did not have gravity? How would Equestria be? Would I be floating? Or would it be normal? Does this mean the pegasi would be useless? What would happen to Rainbow Dash?
Your Faithful Student,
Twilight Sparkle.
Dear Twilight Sparkle,
I have tested a spell out to remove all gravity in the Canterlot throne room once. It was most amusing watching the Nobles walk in and float to the top. Liquid curled up into balls and floated around, which would be very bad if that happened to our rivers and seas. Waterfalls would stop working, so the one in Ponyville would be pointless. Water based animals would also be confused, having to swim round in circles.
Equestria would be very different. Farming apples would be extremely easy yet slow, thus making farming too easy. Life would be too easy, except you won't be able to hold everything securely. Cloud homes would not be unique as people can have their houses float. Rain and snow would not be able to happen. It would make the pegasi obsolete.
Yes you would be technically floating. It would be normal if Equestria never had any gravity though. Sorry, I just had to get Luna's Ponystation out. She is really excited for this 'Dishorned'... No idea what that is.
Rainbow Dash would also be useless, nothing for her to do except sleep. I had a really hard think about this question, which is why it took me so long to write back. Anyway, if you want to test out anti-gravity, you just need to change your reverse gravity spell. It isn't too hard actually. You have books in A and G about the matter.
