How astronomers used gravitational lensing, a space-time trick predicted by Einstein, to detect a black hole measuring 30 billion times the mass of the sun.

Predicted by Einstein and dismissed as undetectable, gravitational waves were finally heard in 2016. Now, with observatories ...

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, ...

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 ...

A new cosmological simulator logs its scientific predictions and refutations in real time, storing hashes in blockchain with full offline ...

These ripples in space-time that Albert Einstein predicted existed 100 years ago can be caused by a massive pair of objects in accelerated motion around each other, such as two merging black holes.

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

Suppose the birth of the universe was not a definite start, but a cosmological rebound far within a black hole? This radical idea has been picking up steam as new theoretical research, spearheaded by ...

DUT Quantum Simulator interface: a decentralized scientific tool for testing cosmological hypotheses based on non-singular ...

NASA, ESA, and ground observatories have detected powerful space explosions caused by black holes tearing apart massive stars ...
