Recent James Webb Space Telescope data confirms a decade-old theory that the universe's earliest supermassive black holes ...

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

Will two rare supernovas finally tell us how fast the universe is expanding? Perhaps, but we'll have to wait for it for them ...

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 ...

From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens in the cosmos. It shapes planets and people, bends light into celestial ...

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

For more than a century, physics has treated space and time as the smooth stage on which the universe unfolds, a flexible fabric that bends but never breaks. A new wave of theories is now challenging ...

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

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. In 1935, ...

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 ...

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

How many electrons are there in the Universe? One bold theory suggests that there could only be one, although this theory has ...
