Scientists have for the first time detected black holes eating neutron stars, “like Pac Man”, in a discovery documenting the collision of the two most extreme and enigmatic objects in the Universe.
The Laser Interferometer Gravitational-Wave Observatory (LIGO) in the US and the Virgo gravitational-wave observatory in Italy have captured the gravitational waves from the death spiral and merger of a neutron star with a black hole, not once but twice.
The researchers say their observations will help unlock some of the most complex mysteries of the Universe, including the building blocks of matter and the workings of space and time.
Black holes swallow neutron stars like Pac-Man

Scientists have for the first time detected black holes eating neutron stars, like Pac Man , in a discovery documenting the collision of the two most extreme and enigmatic objects in the Universe.
The collisions occurred one billion years ago.
The Laser Interferometer Gravitational-Wave Observatory (LIGO) in the US and the Virgo gravitational-wave observatory in Italy have captured the gravitational waves from the death spiral and merger of a neutron star with a black hole, not once but twice. The findings are published today.

(CNN) Nearly a billion years ago, two of the most extreme objects in the universe came together in a death spiral, and one of them didn t make it out alive.
For the first time ever, astronomers have detected two separate instances of black holes swallowing dense neutron stars and it played out like Pac-Man in space.
The gravitational waves caused by these two events reached Earth in January 2020, allowing astronomers to retrace the ripples in space-time back to when they occurred in distant galaxies 900 million light-years and a billion light-years away.
The study, involving more than a thousand scientists in these detections, published Tuesday in The Astrophysical Journal Letters.
