Warp drive has quietly shifted from pure fantasy to a live topic in serious physics, with new models showing how spacetime ...

Warp drive has long been shorthand for “pure fantasy,” a narrative device that lets starships hop between stars without ...

A straightforward math tweak could bring tachyon fields into line with the rest of physics. Tachyons are faster-than-light particles, and tachyon fields are special cases of quantum field. The math ...

Engineers have found a way to shepherd microrobots with no wires, no radios, and no onboard computers. Instead, they steer them with light patterns designed using the same math physicists use to ...

A framework that relies on college-level mathematics could describe what happens to particles in so-called spacetime rips, gravity fluctuations such as those that occur during the birth of a black ...
