Physicists Find a Way to See the ‘Grin’ of Quantum Gravity
...nature of gravity and space-time must be revealed — always hide behind the horizons of black holes. “Even a few years ago it was a generic consensus that, most likely,...
Physicists Mourn Joe Polchinski, Developer of Deep Ideas and Paradoxes
...share of lasting developments without following trends or getting into ruts. In important recent work, Polchinski reinvigorated an old paradox about black holes. Quantum fluctuations near the horizons of black...
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....
Earliest Black Hole Gives Rare Glimpse of Ancient Universe
...fog and figurative mystery. They want to know what burned the fog away: stars, supermassive black holes, or both in tandem? And how did those behemoth black holes grow so...
Plunge Into a (Virtual Reality) Black Hole
...with curves in the space-time fabric, space-time ceases to curve smoothly inside black holes, or even to make sense. Knowing what happens inside black holes would reveal the unknown, quantum...
‘Crazy’ Supernova Looks Like a New Kind of Star Death
...pair-instability, at which point, finally, they gravitationally collapse into black holes. (If Woosley’s theory is correct, there ought to be an absence of black holes over a certain mass range,...
Squishy or Solid? A Neutron Star’s Insides Open to Debate
...come from black holes, which are more tractable beasts from a computational standpoint. But this signal involved lighter objects and went on for much longer than the black hole mergers....
Newfound Wormhole Allows Information to Escape Black Holes
...University, the repulsive negative energy in the wormhole’s throat can be generated from the outside by a special quantum connection between the pair of black holes that form the wormhole’s...
Neutron-Star Collision Shakes Space-Time and Lights Up the Sky
...discovery that earned the experiment’s architects the Nobel Prize in Physics this month. Three more signals from black hole collisions followed the initial discovery. Yet black holes don’t give off...
