Wormholes sit at the edge of science and storytelling, promising shortcuts across the cosmos and even pathways through time.

If the universe was a soundtrack, we have been humming it our whole life. Every atom in our body, every star in the sky, every beam of light is part of a piece of music that never stops playing.

Einstein’s Theory of General Relativity is currently our best approximation of how the universe ticks. But there are holes.

In this last part of our series on recently digitized books from the Wenner Collection, we are focusing on works that ...

Researchers in Germany argue that a modified theory of gravity could explain universal expansion, removing dark energy from ...

A new discovery reveals Cloud-9, a starless gas cloud that offers fresh insight into galaxy formation in the early universe.

The Dark Energy Survey mapped 669 million galaxies to help understand why the universe's expansion is accelerating rather than slowing down.

The theory that gravitons lose energy thru gravitational redshift while traveling against the force of a gravitational field ...

The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make ...

Time does not pass at the same speed on Earth and the moon; with lower gravity, lunar clocks run faster by around 56 ...

Scientists propose a new gravity theory using Friedmann equations. Their model explains the universe’s accelerating expansion ...

The answer comes from a counterintuitive result of special relativity, a field of physics which is notoriously difficult to ...
