These claims are at best incomplete, since the arguments as presented only assert but do not prove the existence of one set of timelike observers, the co-moving Eulerian observers, who see relatively “nice” physics. While these particular observers might…</p><p><a href="https://hackerpaper.kaipfister.de/p/2205.15950/">Paper and discussion history</a>. A mention is not an endorsement.</p>gr-qc
