This is the first spacetime to be written down in which a warp-drive is not required to have exotic negative energy. That one ...

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 ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

A violent stellar disruption recorded in 2024 has given astronomers their most comprehensive evidence yet of a black hole twisting the very fabric of spacetime around itself. This effect is known as ...

When molecular biologist Francis Crick tripped on the psychedelic drug LSD in 1953, his mind famously pulled together all of his previous research on human DNA to conceive of the image of a double ...

The geometry of spacetime forms the very foundation of modern gravitational theory, where the elegant interplay between curvature and matter is described by Einstein’s field equations. In this ...

I've been trying to explain quantum physics, forces, relativity, and space-time to my kid and we had a question that I'm finding difficult to find a solid answer to. Background you can skip if you ...

A collapsing warp bubble like the one seen in Star Trek would set space ringing with gravitational waves. When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

A supermassive monster lurks at the center of our galaxy, and astronomers have now discovered that it’s spinning so fast it’s warping the very fabric of spacetime into a football shape. According to ...
