Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned ...

Astronomers using the MeerKAT telescope discovered a hydroxyl megamaser in a galactic merger 8 billion light-years away, amplified by gravitational lensing and operating at radio wavelengths.

A new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into ...

Energy-momentum distribution remains a fundamental yet challenging aspect of theoretical physics. In general relativity, the localisation of gravitational energy is obscured by the equivalence ...

Quote of the day by Newton: 1915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 ...
