Astrophysicist (PhD, ANU). Galaxy formation, baryonic Tully-Fisher relation. Currently on unpaid leave from CONICET/UNC in Argentina due to science defunding, based in Sydney. Between my first Nostr note and this one I had a daughter in Australia — Matilda is now two. Just published "Kardashev's Conundrum" — statistically falsifying the standard 1%/yr civilisational energy growth assumption against six decades of real data. Bitcoin's hashrate becomes the natural renormalisation (the KarNak unit). Here for DeSci, real-data science, and conversations at the intersection of physics, Bitcoin, and what comes next. #desci #bitcoin #cosmology #openscience #bitcoinscience #kardashev #sagan #seti #physics

Six decades of global energy data falsifies the standard Kardashev 1%/yr civilisational growth assumption. A linear fit wins (ΔWAIC=5.5), pushing Type II out to ~10^15 years. Bitcoin's hashrate gives a clean renormalisation (the KarNak unit).
