Great job yet again Petey ! Thats a really good AND rather simple way of visualizing the phenomenon. I never even thought of that, though I don't ever recall a flatty claiming it doesn't happen. On a related topic, In case anyone is interested, check out spencer conner's newish vid about the AntiKythera mech. Its mostly just awesome machining but he does cover the equations to get the gear ratios & pivot points & such to match the various cycles. Blows my mind that humans were that clever so very long ago.
A beautiful and elegant demonstration. It's remarkable that the apparent complexity of planetary motions results from the underlying simplicity of a centrally-acting force that obeys the inverse-square law. Everything else follows from that.
A wonderful demonstration of retrograde motion. I look forward to hearing from any flattard about how any of this can work on their special little FE terrarium.
Cheers Marc. In FE land, planets in retrograde are just special lights in the sky bouncing of the dome every now and then. No other explanation for it. 😁
@@Petey194 Serious question: I discovered yesterday that your channel wasn't in my list of subbed channels, although I definitely subbed you. Anybody else mentioned this so far?
Thanks roohif, nice of you to say but I learn from you, 🤣🤣 Truth be told, it was you that got me interested in math and geometry again for the first time since high school, so back at ya! 😊
I'm reminded of an old friend that seems obsessed with astrology. She's always 'extra careful when mercury is in retrograde'. Although you didn't explicitly mention mercury, you can see from some of your animations where mercury is in retrograde almost half the time!! So yeah, chances of something 'bad' happening while mercury is in retrograde is about 50/50 lol. Another great animation as always. You're talents with this tool are impressive.
I might be teaching a high school astronomy class next school year. Many of your programs would be a huge asset to my class. Would it be okay to use them for my classroom?
Sure, no problem. Just remember I'm not an expert in any of this and I'm learning as I go, hoping others will correct me if I make mistakes. 😊 For me it seems I learn a new way of constructing something everytime I use Geogebra.
Here is another link from another creator that also demonstrates the retrograde Let me know if the link doesn't work. ua-cam.com/video/ro6K44ebGMg/v-deo.html
@@Petey194 My “guess” is that the rotation of the earth causes Venus to disappear below the horizon. My comment was a sarcastic dig at any flatties who might be trolling here🙂

Excellent. I like a good visual to help comprehend what is taking place with retrograde motion.
Thanks Alex. I appreciate it. I've decided my next video will be about @The-Final-Experiment showing why Antarctica gets 24hrs of Sun in December! 👍
One again brilliantly done! I wonder when the first iD ,ten ,T will show up.
hehe, thanks 😊
Nicely done!
You must now be an expert in GeoGebra!
I think I have the basics down now, 🤣 Thanks for the inspiration!

Thanks cyg. You mean this ua-cam.com/video/mTsCx0E7YkA/v-deo.html Looks very interesting. Yeah, there have been some smart cookies throughout time.
@@Petey194 yup thats it .... there are some others I think ..... but I heard someone mention that one & it was well worth the watch imo

Another cool Antikythera mechanism;

@@Petey194 aww shucks! I don’t know what to say 🥹 😁
Demonstrates the retrograde plainly enough even Brian and Flatz can understand it.
Enviable use of geogebra as well.
hehe, thanks Phredro. I doubt they'll want to understand it.
Wow Petey, this was brilliant! I’ve never seen anything like this. Thanks!👍
Thanks David. You're too kind. Do you think any flerfs have an explanation for these wandering stars? 🤣
@@Petey194 My pleasure. Other than “they’re just lights in the sky”? Only thing I’ve heard is “nuh-uh.”
I don't think you need R for that.

Thanks Mike. Just tell her Venus transiting water signs cancels it out! :P

Brilliant demonstration there, Petey!

geocentrism did exactly the same , so much so that relativity had to be invented to run from it
Aces.
Last night, I watched Venus “set”, just like the sun. What causes that to happen? 🤔
What's your best guess?
