A century after Albert Einstein sketched out his radical picture of gravity, astronomers have now watched a black hole ...

The fabric of space and time is not exempt from the effects of gravity. Plop in a mass and space-time curves around it, not dissimilar to what happens when you put a bowling ball on a trampoline. This ...

For the first time, astronomers have directly observed a spinning black hole bending space and time, as predicted in Albert ...

Astronomers have seen spacetime itself wobble near a spinning black hole for the first time. The discovery, revealed during a star’s destruction, confirms a major prediction of Einstein’s theory of ...

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 ...

Some discoveries arrive quietly, without fireworks or clean endings. Astronomers were watching a distant flare from a galaxy ...

The Princeton that Albert Einstein knew in 1933 was sharply divided by the color line; a long-established border—marked by ...

Laments about the state of education are arguably as old as education is, or close to it. And they’ve always been a waste of time. That’s because knowledge isn’t bestowed on us as much as it’s created ...

"This unique lensing configuration allows us to constrain both the Hubble constant and dark energy parameters simultaneously — something that is generally not possible." When you purchase through ...
