Your 'experiment' would not prove anything. If I had the lenses I could do shots to match those pics. You cannot just move a satellite higher. They each have a specific purpose and it's expensive to get them in place.

The theory of gravity has been very well tested and found to work in all cases.

Actually radio can get around the Earth to some extent by bouncing off the ionosphere. That was done before Loon or fibre optics.

Proving tides? They happen and can be seen on any coast. They are also well predicted based on the motion of the Moon. How else is all that water moving up and down?

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

Eh? Sorry, but you are just making stuff up. A lot of this stuff was known hundreds or even thousands of years ago, long before NASA. I'll talk to you about podcasts, but this discussion is pointless if you have set your mind against science.
