I have some "flat Earth friends," and I just can't talk to them about that topic. It's often people who "woke up" during the pandemic and then decided, that as you stated, if Fauci et al lied, then all of consensus reality was up for grabs: The Earth is flat. Viruses don't exist. The "White Hats" are secretly working to overthrow the Deep State. I'm sure I'm forgetting some things. It's bonkers.

A laser beam has no mass and is therefore unaffected by the earth's gravitational pull (said Einstein I think). However, a laser beam transitted horizontally over a long distance would, due to the earth's curvature, appear at the receiving end to be at a higher elevation above ground. In experiments this doesn't happen, it remains at the same height. I'm no flat-earther but I've never been told how this is possible.
