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

A black hole can feel like the most distant and unreal object you could ever think about, yet the way its darkness bends ...

Recent advancements in observational techniques have led to the capture of high-resolution images of black hole shadows, ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

It might not be obvious to those of us only grappling with more mundane concerns, but for cosmologists bent on unlocking the universe’s deepest secrets, there’s no shortage of problems keeping them up ...

Whenever someone talks about black holes, they almost always talk about the event horizon and the singularity. After all, ...

General Relativity, Einstein’s revolutionary theory of gravity, reinterprets gravitational interactions as phenomena emerging from the curvature of spacetime rather than as forces in the traditional ...

An international team led by Japanese researchers has made a 3D map of 3000 galaxies 13 billion light years from Earth, and found that Einstein’s general theory of relativity is still valid. Since it ...

If you asked an astrophysicist what is yet to be discovered in the universe, there’s a good chance they’d paraphrase Donald Rumsfeld: It’s full of known unknowns. Besides the regular matter and energy ...

A straightforward math tweak could bring tachyon fields into line with the rest of physics. Tachyons are faster-than-light particles, and tachyon fields are special cases of quantum field. The math ...

Researchers are using black hole “shadow” images to test whether Einstein’s relativity remains unshakable. With next-generation telescopes, they hope to spot telltale signs of alternative physics ...

Black hole complementarity may force us to rethink what it means to say that it exists. Black holes clash in multiple ways with quantum mechanics. One such clash is the black hole information ...
