Neutrinos Linked With Cosmic Source for the First Time
...tracing ultrahigh-energy neutrinos back to their astrophysical source. That source appears to be a supermassive black hole at the center of a distant galaxy. Every time a black hole gobbles...
How Our Reality May Be a Sum of All Possible Realities
...approach to argue that information leaks out of dying black holes. This “seems to be the richer point of view to take,” said Simon Ross, a quantum gravity theorist at...
Dark Matter Recipe Calls for One Part Superfluid
...field with two colliding black holes and you’ll create gravitational waves. Likewise, if you poke a superfluid, you’ll produce phonons — sound waves in the superfluid itself. These phonons give...
Eva Silverstein’s Spirals and Strings
...down sensible equations about what might happen inside black holes or during the Big Bang. But string theory describes invisibly tiny details of reality — vibrating strings at the hearts...
To Solve the Biggest Mystery in Physics, Join Two Kinds of Law
...the phenomenally successful reductionist approach of the past centuries, John Wheeler, the influential Princeton University physicist whose work touched on topics from nuclear physics to black holes, expressed an interesting...
What Makes the Hardest Equations in Physics So Difficult?
...as water flowing through a hose, so much harder to understand mathematically than, say, Einstein’s field equations, which involve stupefying objects like black holes? The answer, I discovered, is turbulence....
On the Best Use of Science to Safeguard Humanity
...in astronomy? Well, so much new information was coming in. You saw the first evidence of the Big Bang, black holes, quasars. Think about this: I was only a first-year...
With a Second Repeating Radio Burst, Astronomers Close In on an Explanation
...might also make FRBs when they crash into other objects like black holes or white dwarfs, when they themselves collapse into black holes, or when their magnetic field lines are...
The Hidden Heroines of Chaos
...a sharp pencil. “I’d poke holes for ones, and I’d cover up with Scotch tape the others,” she said. “He just got a kick out of it.” There were desks...
