In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley ...

In 2023, scientists detected the gravitational waves from a black hole collision that seemed impossible. New research finally ...

"The key result is that while many alternatives look very similar to the 'standard' black hole at today's image quality, the ...

Kellogg Stelle was a professor of physics at Imperial College London for decades until his death last month. In 1977, he developed a particle theory of gravity that’s renormalizable, but the theory’s ...

Black holes, regions of spacetime in which gravity is so strong that nothing can escape, are intriguing and extensively ...

In this video, we explore Albert Einstein's theory of general relativity, focusing on his insights into gravity and ...

James—who secured a $454 million judgment against President Donald Trump for civil business fraud—was indicted in the Eastern District of Virginia. The indictment comes months after the Federal ...

A gravitational singularity refers to a point in spacetime where density and curvature become infinite, and the equations of general relativity no longer provide meaningful predictions. Theoretically, ...

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 ...

Epithelial cells line the body’s surfaces to protect against physical damage, pathogens, and dehydration. These cells play key roles in absorbing nutrients and removing waste products, as well as ...
