At stake are fundamental ideas about how black holes form — and a six-way bet.
New measurements could upend the standard theory of the cosmos that has reigned since the discovery of dark energy 21 years ago.
Although Einstein’s theory of space-time seems more complicated than Newtonian physics, it greatly simplified the mathematical description of the universe.
Opinions differ about what recent measurements of a sound-trapping fluid reveal about light-trapping black holes.
