For reference, human beings
cannot see objects in the thermosphere and beyond in broad daylight. That puts it in the stratosphere or mesosphere
at most.
To say nothing of the that as Earth is orbiting and rotating and generally "wobbling" all about, its temperature from one day to a next should not at all be constant. Yet temperature nearest the equator is constant.
It's magic, folks! Don't question it. You'd probably burn well before that flip happened, but is somehow you didn't, at Earth's center there would be some kind of gravity well.
Open a bottle of water! Those flat Earthers will find out in a hurry that water is curved when it comes spouting out in a stream straight upwards. What's that you say? You were pressing the sides of the bottle? Nonsense!
Uhhhh, this isn't a valid point. But I also had to include it.
I think this is because they would immediately lose credibility if they showed Earth as a pear.
Honestly, I don't know enough about lens to confirm or deny this one. But
this seems to verify this.
Ever notice that these high speeds seem like something a little kid made up? 67000 mph might as well be "eleventy zillion." Whereas a near-orbit sun would need to move relatively slow to make it around the Earth.
Why do there seem to be all of these phone towers? I mean, couldn't we get all of our cellphone service from space? Almost like these satellites can't actually do anything about this...
And finally,
If I hear one more stupid person deciding that humans would have to lay flat for a flat Earth... Let's review. You can sit on the top of a circular desk. You can even stand on it, if you're light enough that it will support your weight. I'm going to give you homework. Stand on top of a beach ball.
Fallen over yet? Good, cuz now I'm going to laugh at you.
