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 ...

As new and powerful telescopes gather fresh data about the universe, they reveal the limits of older theories like Einstein's relativity. When you purchase through links on our site, we may earn an ...

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 ...

Aligarh, Dec. 29 -- day National Workshop titled"Introductory Workshop on General Relativity and Gravitation (IWGRG-2025)". Organized in collaboration with IUCAA, Pune, and supported by ANRF and CSIR.

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

In 1994, physicist Miguel Alcubierre proposed a radical technology that would allow faster than light travel: the warp drive, a hypothetical way to skirt around the universe’s ultimate speed limit by ...

Unifying quantum mechanics with general relativity is the ultimate dream — or nightmare — of physics. It would be a way to finally describe the force of gravity with the tools of quantum mechanics, ...

Einstein was right: artist's impression of a neutron-star merger. (Courtesy: NASA) Multimessenger observations of neutron stars have been used by astrophysicists in the US to put Einstein’s general ...

Black holes seem to get all the attention. But what about their mirror twins, white holes? Do they exist? And, if so, where are they? To understand the nature of white holes, first we have to examine ...
