How Photon Torpedoes Will Mark An End To The Energy Crisis


Photon torpedoes come after utopia, at least in Star Trek. Imagining a universe centuries ahead of our own time and technology, the long-running sci-fi shows explored philosophy, morality, and the secluded intricacies of physics. But what was left unstated said the most. By the time Jean-Luc Picard took the captain’s chair, poverty in the 24th [...]

Physics is all about probing the most fundamental mysteries in nature, so it’s no surprise that physicists have some very basic questions about the universe on their minds. Recently, Symmetry Magazine (published by two U.S.-government funded physics labs) asked a group of particle physicists to name the open questions in physics they most want answers [...]

A superluminous supernova may sound like a designation dreamed up by someone with a penchant for hyperbole, but such explosions are deserving of the extravagant language. They are very big blasts—and two newfound examples originated in the very distant past. Astronomers using two telescopes atop Mauna Kea in Hawaii have discovered a pair of supernovae [...]

Magnetoastrocoolness: How Cosmic Magnetic Fields Shape Planetary Systems

AUSTIN, Texas—Astrophysicists have a funny attitude toward magnetic fields. You might say they feel both repelled and attracted. Gravitation is assumed to rule the cosmos, so models typically neglect magnetism, which for most researchers is just as well, because the theory of magnetism has a forbidding reputation. The basic equations are simple enough, solving them [...]
