If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. When you purchase through links on our ...

What if the biggest change in warp-drive research is not speed, but credibility? For decades, the idea sat in an awkward ...

A new high-resolution map of distant galaxies may help scientists understand a mysterious invisible substance that helps hold the universe together. The ordinary matter all around us — stars, planets ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Warp drive research has long occupied the narrow corridor between elegant mathematics and science-fiction wish fulfillment. A recent theoretical result pushes that corridor open a little wider by ...
