Interesting, I’ve always been a little skeptical of a theory that seemed to arrive to make the math work, when it can’t be observed or directly detected. It seems to me that a model that’s not quite complete or correct is a simpler explanation than undetectable energy/matter.
The math working is often a prediction that something can be directly detected, but yes if the math works but reality doesn’t match the math, then something’s wrong. Also by undetectable energy/matter do you mean dark matter? Dark matter is just a placeholder term, and yes, it just means that our current information is missing something.
Read about Einstein and the precession of Mercury. Numbers do not lie.
Numbers don’t lie but the ways in which we use them certainly can. Something not matching up generally means the math being used is not accounting for something. In the case of the procession of Mercury, the math of Newton’s model fails to accommodate that procession, while Einstein’s newer model did.
I’m still bummed there is no Vulkan.
I teach physics at Xavier University, and incorporate some yoyo into it, but only sporadically. I’d love to see what you do in your unit, Ed.
Oh yes!
I am more of a practical understanding of mechanical processes. I understand how CG works, how MOI applies to a yoyo, and how the overall size of a yoyo effects it’s properties.
I also have a working interest in bind theory, and response systems.
As far as the kinetic distribution of yoyo mechanics, how the yoyo works from a classic approach, no I don’t have that much interest.
Oh! Looping, freehand, and off string mechanics interest me too.
Don’t even get me started on ano processes, Al amalgam, and the general manufacturing process.
If you believe the story of the “Big Bang”.
If the Earth is 4 billion years old; I have a hard time believing this all came into existence in a mere 13 billion years.
I agree. It’s a very big if.
That galaxy field in Virgo is so mind blowing.
It certainly does give one a sense of perspective.
Yep, same image I posted.
Yes, not stars; galaxies. It is an amazing Hubble-image. We all eagerly await the next generation of images from the Webb telescope beginning this summer.
It was labeled the favorite Hubble image iirc. Stunning for sure.
Tracking Webb was neat. They had the website show launch and into orbit and now have a linear and 3D image map. Where Is Webb? NASA/Webb
The 1st test image won’t knock your socks off, but it’s working so far!
Edit: You can get an astronaut for your room too. One thing that was amazing about the Northern lights in person was the various crackling and popping sounds of electricity in the air.
A simplified explanation of the ‘centre of the universe’ and null and geodesic incompleteness. Again, derived from scientific insight and not social media research. https://www.youtube.com/watch?v=BOLHtIWLkHg
This is the graphic above that didn’t load fully. It’s not about the center of the universe, but where earth is.
There is a famous brazilian philosopher which approaches this subject in terms of human arrogance.
“Do you know who you are speaking with?” and he lectures about the universe, it’s really worth it:

Nice! Engaging fellow too. ‘Who am I’ is a koan too. Who is the ‘I’ and where does it exist.
The title reminds me of a D.C. quote-
His beginning talk about compression reminds me of the seed quote. Every seed has the entire tree already in it. Every leaf, every limb, every bit of bark is already there inside the seed.
Just made a new 15 minute bull whip today as the old one is beat and saw this on the sidebar! Turns into an audible add 3/4 in, but good until then.
1st man made item to break the sound barrier and some pretty neat physics data and camera capturing!
