The Search for Dark Matter Is Dramatically Expanding
...these detectors have stayed quiet, and physicists are increasingly contemplating a broader spectrum of possibilities. On the heavy end, they say the universe’s invisible matter could clump into black holes...
How to Solve Our Three John Conway-Inspired Puzzles
...holes reduce edges by four (with a weight of 4). So single edges need to be balanced with U’s and/or holes using the following formulas: Singles(s) and U’s (u) only:...
What Is a Particle?
...for calculating the quantum information content of black holes. “You can talk about the abstract existence of 0s and 1s, and how an operator might act on 0s and 1s,...
Debate Erupts Over How ‘Forbidden’ Black Holes Grow
Once missing in action, middleweight black holes have finally been detected. Now researchers are trying to figure out how they grow from small ones. Until recently, black holes — those...
The Most Famous Paradox in Physics Nears Its End
...how paradoxical black holes really are. His first studies of black holes, when he was a graduate student in the ’70s, were key to his adviser Stephen Hawking’s realization that...
A Scientist Who Delights in the Mundane
...in general relativity because inside a crumpled sheet of paper there are many singularities, like black holes, and these singularities can touch and interact with each other. So it’s an...
The Hidden Structure of the Universe
...substance as pervasive as the pre-Einsteinian aether, and just as poorly understood. Physicists probing the paradoxes of black holes have grown convinced that there’s a fundamental connection between information and...
Physics Nobel Awarded for Black Hole Breakthroughs
...to always question what you’re seeing.” Two decades later, there can be no more doubt about black holes and their critical role in the cosmos. What are black holes? Black...
Some Physicists See Signs of Cosmic Strings From the Big Bang
...Way, has a supermassive black hole in its center that weighs million or billions of times more than the sun. If two galaxies merge, their black holes will start to...
