Is the moon 238k miles away?

I have not watched the video. I do know amateur radio operators who have bounced signals off of the moon and received the reflected signal at the exact timing one would expect for the expected distance. Also we know how fast the signal is traveling because if we were wrong about that aspect then we would be cutting our antenna elements to the wrong lengths. So the moon's distance is pretty well established and regular people can confirm this.

Example of radio signals bouncing off of the moon:

Where is the comparison ratio of size of Prudential bldg. v. size of moon? Without that his zoom experiment is a fail and his conclusion is incorrect.

On July 20, 1969, Neil Armstrong and Buzz Aldrin left a mirror on the lunar surface so scientists could hit it with lasers for accurate ranging.

The Soviets later installed a few French-built retro-reflector arrays. A laser pulse is fired at the mirror and the delay in the return laser pulse is computed using c (speed of light). It takes roughly 2.6 seconds for the laser pulse to make the round-trip.

Of course, the scientific measuring equipment measures the delay to 5 decimal places, so the (computed) distance from the Earth to the moon (238,855 miles) is accurate within a couple of miles. The Moon is drifting away from Earth, so the distance is always increasing.

The video is pure nonsense. Ill bet he thinks the Earth is flat!

You are assuming it even exists, not just a product of a high tech or other fake:

Richiefromboston has inhaled too much baked bean exhaust.
There are way too many people underemployed, probably largely due to the floods of illegals and other foreign workers; leaving many spending endless hours on these sites or ogling, salivating over and jerking off to porn. Not a good situation.....

Probably never enjoyed it when served up by a hot sexy babe!
He'd probably be more interested in eating Kay than kale? Yeah...I can see that.
