To prove the earth is round an experiment is needed from a very high elevation.
You might not be able to mount a scientific investigation to your nearest mountain peak. But there is something you can do to witness the curvature of the Earth in the comfort of your own backyard, You just have to be lucky.
During a lunar eclipse, the Earth passes between the sun and the moon, allowing the Earth to cast its shadow on the moon. That shadow is always, always always a circle, no matter where you are on the planet, no matter the timing of the eclipse. Always..
The only way to always cast a circular shadow is if the thing casting the shadow — in this case, the Earth — is a globe. It’s just a matter of geometry.
And that’s not to mention the countless photographs taken of Earth by orbiting satellites and eyewitness testimonies from astronauts hailing from dozens of different countries, space programs and private organizations.
Our curved Earth also aligns perfectly with all of physics.. Additionally, all of the other planets ever discovered also appear round, because that’s how gravity likes things.
If you use gravity to, say, trust your GPS to give you accurate positions and calculate trajectories, then that same force will form material the size of the Earth into a ball.
Flat earthers are not persuaded by scientists or anything else as they just mistrust scientists and world powers. They are beyond reason.
