Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first predicted by Albert Einstein back in 1915, could have given rise to cosmic ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

Astronomers used a method once theorized by Albert Einstein to find a mysterious and rare planet on the edge of our galaxy. The planet, AT2021uey b, is a Jupiter-sized gas giant located about 3,200 ...

"This discovery was partly serendipity! But, we believe there are many more such opportunities hidden in Hubble data." Astronomers discovered a new rogue planet lurking in archival data gathered by ...

When it comes to space travel, Albert Einstein's theory of relativity is a major inconvenience. With the laws of physics (currently) prohibiting faster-than-light travel, velocities are limited to a ...

"If the model holds true, it could mark a new chapter in the way we think about the birth of the universe." A radical new theory regarding the origin of the universe suggests that gravitational waves, ...
