I’d go and hang out with the upside-downers. They are a lot more fun.

That's like asking if you found out that evolution wasn't true: where's the proof?

Someone explain to me this. I’m not defending nor insulting the OP in any way. Why is it the majority of people assume the person asking the question has a stance either way? And then many are quick to insult and ridicule. They didn’t say they thought it was flat. They asked what in your life would change if you found out a widely assumed, researched, and quantified fact was proven incorrect. We are always so quick to judge. At the least ask for clarification. Rant over.
