It is even possible to fit a warp drive within the equations of Einstein-and still make it practically unavailable. Over ...

Imagination has never been the most intractable problem in the physics of warp drive; it has been bookkeeping. The Alcubierre concept of 1994, the celebrated one, fits in the general relativity theory ...

Albert Einstein's general theory of relativity describes gravity as the warping of space-time geometry by mass, a concept distinct from Isaac Newton's absolute space and time, and has been empirically ...

A century ago, Albert Einstein became famous. Sure, he was already well-known among physicists. But the world at large learned his name only after November 1919, when news broke that his theory of ...

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 ...

Albert Einstein’s general theory of relativity is one of the towering achievements of 20th-century physics. Published in 1916, it explains that what we perceive as the force of gravity in fact arises ...
