A new study published in Physical Review Letters explores the possibility that a strongly supercooled, first-order phase transition in the early universe could explain gravitational wave signals ...

In 2023, physicists were awed to find nearly imperceptible ripples in the fabric of space and time — united as an entity known as spacetime. They were ripples discovered in association with ...

The radio waves we see from pulsars have a mysterious glitch – but now we know the ingredients that must be present in the heart of these ultra-dense stellar corpses to give their emissions a hiccup.

Add Yahoo as a preferred source to see more of our stories on Google. The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments ...

A closed door feels absolute. Light stays in one room, darkness settles in the next, and the boundary seems obvious enough to ...

A Harvard study shows that soft materials, like gels and biological tissue, support boat wake-like surface waves. Because wake shape encodes material properties, th ...

New multiscale simulations help crack long-standing mysteries behind the enormous radio arcs generated when galaxy clusters collide. When you purchase through links on our site, we may earn an ...
