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

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, ...

"We would need to consider the possibility that the source was created (or trapped as a primordial black hole) by a highly advanced technological civilization," Harvard's Avi Loeb writes.

These black holes are the most distant and stable objects we know. Using a technique called very long baseline interferometry ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in ...

Could the Universe have been born inside a black hole? This question, raised by a team of scientists, challenges the Big Bang ...

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

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

The colossal black hole lurking at the center of the Milky Way galaxy is spinning almost as fast as its maximum rotation rate. That's just one thing astrophysicists have discovered after developing ...

New findings about intermediate-mass black holes could shed light on some of the universe’s more mysterious components. In a recently published paper, a group of scientists have found new evidence of ...

There are objects in our universe so dense that not even light escapes through them. These oddities, known as supermassive black holes, can weigh billions of times more than our sun. Scientists have ...

Black holes are invisible, yet they are among the brightest things in the universe. If a star wanders too close to a black hole, it gets torn apart in a fireworks show called a tidal disruption ...
