Joint Dust Analysis Deflates Big Bang Signal
No definitive evidence for cosmic inflation is found, but support remains strong for the theory even as critics highlight its shortcomings as an explanation for how and why the universe began.
Quantum Computing Without Qubits
A quantum computing pioneer explains why the near future of quantum computation may lie in simulators, not general-purpose quantum machines.
Scientists Conjure Curves From Flatness
Researchers have found a set of rules for imbuing flat surfaces with curvature, enabling them to form a virtually unlimited range of three-dimensional structures.
A Common Logic to Seeing Cats and Cosmos
New research suggests physicists, computers and brains employ the same procedure to tease out important features from among other irrelevant bits of data.
Multiverse Collisions May Dot the Sky
Early in cosmic history, our universe may have bumped into another — a primordial clash that could have left traces in the Big Bang’s afterglow.
In a Multiverse, What Are the Odds?
Testing the multiverse hypothesis requires measuring whether our universe is statistically typical among the infinite variety of universes. But infinity does a number on statistics.
Dwarf Galaxies Dim Hopes of Dark Matter
For five years physicists have been tantalized by possible evidence of dark matter in the Milky Way’s center. But new results from small satellite galaxies have complicated the story.
At the Far Ends of a New Universal Law
A potent theory has emerged explaining a mysterious statistical law that arises throughout physics and mathematics.
‘Big Bang Signal’ Could All Be Dust
Cosmic dust in the high latitudes of the Milky Way could account for the entire swirl pattern that had been presented as proof of a leading Big Bang theory, according to a new data analysis from the Planck satellite.
