!physics Friday release: Inertial Reference-Frame Interaction Hypothesis (IRFIH)
Nested inertial frames—Earth, Sun, Galaxy—can exchange angular momentum. IRFIH derives a coupling term matching mm/s fly-by Δv still unexplained by GR.
Plain Lagrangian mechanics; no new constants. Predicts measurable effects on upcoming GEO-transfer perigees.

Hey! 👋 I'm Isaac, Mathematician and Data Scientist from Spain, currenly doing my PhD in #astrodynamics and #artificialintelligence
Overall nerd, I'll mostly post about #technology #science #gamedev and #books .
I also like doing cool math art with processing, so I may post some of those from time to time...
