##### Distance to the Moon?
« on: October 28, 2018, 04:21:03 AM »
Every tool known to man that measures and calculates the distance the moon is from the earth to be 239k miles, give or take.

What tools do FET use to calculate that distance to be 3k miles?

I'd imagine that they use congruent triangles. If the moon is at its zenith and at the equator, you can know how far away it is horizontally, based on the radius of earth and your position. You can then measure how long the shadows are relative to the objects that cast them, and apply that ratio to the moon's horizontal position to find its height. A good way to test the FET would be to preform similar geometrically sound experiments from different angles, and see if the results are consistent. I haven't seen anyone do this, though.

You could also actually measure the distance using the reflectors on the moon...

But then that would disprove FET's idea of how far away the moon is so no flat earther would ever do that.

Using any reflectors on the moon would presume that there was actually a mission to the moon that has been deemed 'fake' by many on this site.  You don't actually have to use those reflectors at all.  Radio waves can be bounced off the moon.  Amateur radio operators have been using the moon as a reflector for a long time.  It's a straight forward process to send a pulse to the moon, then measure the time it takes to come back.  Since the speed of radio waves is well known, you can calculate the distance. Radars can also measure the range to the moon as well.
You can lead a flat earther to the curve but you can't make him think!

how big of a radio pulse do you need? If its small enough, that actually sounds like a good way to prove the moon's distance.

At the speed of light and with a distance to the moon of about 238855 miles you would expect a radio signal to return in about 2.5 seconds.  You don't really need a pulse, just a regular radio and an antenna with plenty of gain.  It doesn't have to be mounted on a big tower, you just have to point it at the moon.  If the moon is only 3000 miles away then the delay will only be about 30 milliseconds.  You would be able to hear with your own ears the difference in those two times and you would know for sure.
