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. ---

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. ---

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. ---

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?
