Some physicists think our reality is a kind of cosmic hologram, with space, time, and gravity as manifestations of a ...

Very massive stars are cosmic "rock stars" that live fast, die young and leave black holes in their place. During this ...

A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of ...

Caltech simulations reveal what happens when black holes collide with neutron stars—violent cracking, intense shock waves, ...

A controversial theory suggests the observable universe is the result of matter rebounding after the collapse of a black hole ...

The Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood, ...

A new generation of black hole research is unfolding thanks to artificial intelligence, massive simulations, and cutting-edge ...

Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the ...

Unlike typical black holes, which have a spherical shape, a planar black hole's boundary is a flat, two-dimensional surface. The researchers' ongoing work suggests that the same mechanism could ...

The black hole at the center of our galaxy is experiencing a flurry of flares, ranging from flickers to brilliant eruptions, according to a team that analyzed data from recent observations by the ...

A mind-bending hypothesis is gaining traction among scientists: The universe may be teeming with microscopic black holes the size of an atom, but with the mass of a city-sized asteroid. Created ...
