A globe-spanning group of physicists used pulsars to measure the waves, which they believe emanated from pairs of supermassive black holes. ..
The quantum energy teleportation protocol was proposed in 2008 and largely ignored. Now two independent experiments have shown that it works. ..
New calculations suggest that the event horizons will eventually “decohere” quantum possibilities—even those that are far away. ..
Phil Plait’s new book, Under Alien Skies, helps space fans imagine what it would be like to visit stars and other worlds. ..
Scientists are using secondary signatures from the cosmic microwave background to map the universe’s hidden matter. ..
In three-dimensional space, the surface of a black hole must be a sphere. But in higher dimensions, an infinite number of configurations are possible. ..
Two physicists find that our universe has a higher entropy—and is therefore more likely—than alternative possible universes. ..
Telescopes around the world are capturing photons from the blast, and researchers anticipate exciting discoveries ahead. ..
Supermassive black holes are engines of galactic evolution, but new observations of our galaxy and its central hole don’t quite match expectations. ..
