“The whole thing is very hypothetical at this point,” Stephen Hsu said of wormholes, a caution that still defines the subject even as the idea keeps resurfacing in serious physics. The appeal is ...

For most of the past century, wormholes sat comfortably in the realm of science fiction, a mathematical curiosity that let storytellers fold space like paper. Now a series of bold experiments and new ...

A new experiment using Google’s Sycamore quantum processor has taken a bold step toward testing ideas from quantum gravity. For the first time, researchers successfully sent quantum information ...

When scientists first sent microscopic worms into orbit in 2018, they hoped to answer a question that has shaped every discussion about long missions. What really happens to your body when gravity no ...
