In a new paper, physicists argue that hypothetical particles called axions could explain why the universe isn’t empty.
A proposal for building wormhole-connected black holes offers a way to probe the paradoxes of quantum information.
For the first time, physicists have calculated exactly what kind of singularity lies at the center of a realistic black hole.
Physicists have long searched for hypothesized dark matter particles called WIMPs. Now, focus may be shifting to the axion — an ultra-lightweight particle whose existence would solve two mysteries at once.
Calculations involving a higher dimension are guiding physicists toward a misstep in Stephen Hawking’s legendary black hole analysis.
A close look at fundamental symmetries has exposed hidden patterns in the universe. Physicists think that those same symmetries may also reveal time’s original secret.
