Physicists observationally confirm Hawking’s black hole theorem for the first time
There are certain rules that even the most extreme objects in the universe must obey. A central law for black holes predicts that the area of their event horizons — the boundary beyond which nothing can ever escape — should never shrink.
The final dance of mixed neutron star-black hole pairs
Gravitational wave detectors have observed a new type of cataclysmic event in the cosmos: the merger of a neutron star with a black hole.
The final dance of mixed neutron star-black hole pairs
Gravitational wave detectors have observed a new type of cataclysmic event in the cosmos: the merger of a neutron star with a black hole. The phenomenon was detected twice in January 2020. Several hypotheses could explain the existence of such…
