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 ...

A new paper from Harvard's sometimes controversial physicist Avi Loeb has suggested that if we want to find advanced alien ...

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 ...

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 ...

K arl Schwarzschild first stumbled upon black holes in 1916, but for a long time they weren’t really a thing. “Black holes were discovered as a purely geometric object — in a sense, just empty space.

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 ...
