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 ...

Over a century ago, a German physicist named Karl Schwarzschild mathematically described what we now recognize as a black ...

A new solution to Albert Einstein's theory of general relativity suggests hypothetical gravitational stars that look like black holes could be nested within one another. When you purchase through ...

Black hole singularities defy the laws of physics. New research presents a bold solution to this puzzle: Black holes may actually be a theoretical type of star called a 'gravastar,' filled with ...

The study of black holes and the dynamics at the centres of galaxies has reached new heights with the advent of high-resolution imaging and advanced simulation techniques. Black holes, the enigmatic ...

Karl Schwarzschild, a child prodigy born in 1873, published on celestial mechanics by age 16 and earned his doctorate in astronomy in 1896. His career trajectory included directorships at the ...
