(How to make your own fake moon videos - or how to undo the fake studio videos)

Stop. Don’t say it. I know the moon landings were real, but I am just trying to have fun.

Some claim that the Apollo moon landings were faked in a studio. One way to make fake films would be to film astronauts and then slow the film down so it looks like they are on the moon. If this were the case, I could speed the videos back up to “normal” speed and see what they look like. After that, I will take normal videos and slow them down to make them look like they are on the moon.

You see this all the time in textbooks:

This is often described as “the acceleration due to gravity”. Is this really the best thing to call this? No. A better name would be “the local gravitational field” and list it in units of:

Ok, I this just came up and I had to write something about it (even though I have tons of other things to do). Here is a video of a guy jumping 35 feet into a pool of water only 1 foot deep.

How does this work? Read More...

I am really not sure why I started to look at this, but here is a video of the famous “jump salute” from Apollo 16 astronaut John Young.

It seems there is some discussion about this video in terms of fake or not fake moon landings. I don’t want to get involved in that whole mess, so I will just see if I can measure the gravitational field on the moon. Read More...

I have posted an "online presentation" about weightlessness and gravity. This has taken some time to put together since I had to build some stuff (vomit comet for toys). Anyway, hopefully, you will find this helpful and useful.
