Dark matter made out of axions may have the power to make space-time ring like a bell, but only if it is able to steal energy ...

The Sagittarius A* supermassive black hole at the core of the Milky Galaxy may be "warping the spacetime surrounding it into ...

"This unique lensing configuration allows us to constrain both the Hubble constant and dark energy parameters simultaneously ...

There’s so much mass in this megacluster that its gravity warps the fabric of spacetime to create a natural super-magnifying glass called a “gravitational lens.” It’s that which has ...

Spacetime might seem smooth, but it could, at very short length scales, be quantized. Energetic neutrinos from gamma-ray bursts could provide a useful means to investigate further, and probe the ...

Scientists developed a new model, which provides mathematical evidence that singularities are hidden inside black holes.

Nuclear theorists uncover the mass distribution within the pion and the proton through groundbreaking first-principle ...
