Me too :) You want to change the subject and not attempt my experiment, that's fine.

Ok, so first off, gravity is still a theory (backed by their magical dark matter theory). What is gravity? Gravity is a neat little word which can be used to describe density, buoyancy and the electro-static force though. Those 3 things are provable.

There is 1 pole, not 2. South surrounds us, that has been proven time and again. Compasses don't lie.

Radio transmissions do not curve around a globe, but high-altitude line-of-sight balloon transceivers (google loon for example) and fiber optic lines can get signals around a globe quite easily.

Tides are difficult to prove since we are not allowed to privately explore antarctica or the north pole land (which is getting removed for some reason from many current maps and globes). Please don't say gravity again. Stick to what we can prove.

The huge battery-powered clock that we live on perfectly explains the seasons, star/planet orbits, long-haul navigation, timezones and more.
