And particle physicists are not aware that even without any Quantum Mechanics, classical gravitation dictates that all gravitational collapse must be accompanied by radiation. : http://link.aps.org/doi/10.1103/PhysRevD.74.024010…</p><p><a href="https://hackerpaper.kaipfister.de/p/gr-qc_0605066/">Paper and discussion history</a>.
