Black Hole

At the heart of almost every galaxy lies an enormous black hole. These monsters are so massive that they get a classification of their own: supermassive black holes, with masses millions or even billions of times the mass of our sun. And when two galaxies collide, their supermassive black holes…

A few years ago a team of chemists unboiled an egg. Boiling causes protein molecules in the egg to twist around one another, and a centrifuge can disentangle them to restore the original. The technique is of dubious utility in a kitchen, but it neatly demonstrates the reversibility of physics.…

Credit: Jason DrakefordWe do not have a theory to tell us everything about how a black hole works, but new research is shedding a least some light on one of their many mysteries. Tulika Bose: This is 60-Second Science. I'm Tulika Bose. You probably already know what a black hole…

Home News Science & Astronomy A remastered version of the image of the black hole at the heart of M87 shows its gravitational influence and the 'footprint' of an astrophysical jet. (Image credit: Broderick et al. 2022, ApJ, 935, 61) A newly remastered image of the black hole at the…

How fast is our universe expanding? The Hubble constant is one of the most critical numbers in cosmology because it tells us how fast the universe is expanding. There are different methods exist to measure this rate. However, determining this number’s accuracy is essential to understand better fundamental questions like…

Home News Science & Astronomy Astronomers have photographed a violent cosmic dance that began between two galaxies a billion years ago, pulling them into a collision that birthed a new chaotic galaxy.  At the heart of that giant collision-born galaxy are two supermassive black holes — each once at the…

Black holes, wormholes, entanglement, Einstein, mysterious islands and new science that sees how the inside of a black hole is secretly on the outside. Black holes have been a big problem in physics. For decades, scientists have been mystified about what happens to stuff that falls into a black hole. …
