Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen.

A decades-old idea is quietly regaining attention in theoretical physics: ancient structures embedded in the universe’s ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

"These results from the Dark Energy Survey shine new light on our understanding of the universe and its expansion." ...

By studying ripples in space-time, physicists are testing wheather dark energy might stem from hidden dimensions, elusive ...

The NASA/ESA/CSA James Webb Space Telescope has topped itself once again, delivering on its promise to push the boundaries of ...

NASA’s Roman Space Telescope is set to embark on a deep-sky survey that could capture nearly 100,000 cosmic explosions, shedding light on everything from dark energy to black hole physics. Its ...

In 1905, Albert Einstein revolutionized physics by demonstrating that time is not absolute but relative to the observer's ...
