Black Hole

Where did the universe come from? Where is it headed? Answering these questions requires that we understand physics on two vastly different scales: the cosmological, referring to the realm of galaxy superclusters and the cosmos as a whole, and the quantum—the counterintuitive world of atoms and nuclei. For much of…

It’s been three years already? It seems like Control didn’t come out all that long ago, but I learned today that it’s been three years since the game’s release. Man, time flies when you enter the black hole that is a global pandemic. Seems on theme for Control, I guess. It’s…

NASA’s Hubble Space Telescope has captured an elliptical galaxy M60 (the large, diffuse galaxy at the center) along with the bluish spiral galaxy NGC 4647 (upper right). At the center of galaxy M60 lies a huge black hole that is 4.5 billion times larger than our Sun, one of the…

Physicist and best-selling author Stephen Hawking presents a program in Seattle in 2012. Although he... made some tremendous contributions to science, his analogy about black holes decaying has contributed to a generation of misinformed physicists, physics students, and physics enthusiasts.

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…
