For centuries, we’ve believed gravity holds the universe together. But what if that’s the biggest misunderstanding in science ...

For centuries, gravity has been the cornerstone of physics—but what if it’s not the universe’s true force? The Electric Universe theory claims that invisible cosmic currents shape stars, planets, and ...

If these knots had a slight bias toward matter over antimatter, their unraveling could help explain the matter-antimatter ...

These knots, made of tangled energy fields, may have briefly dominated the cosmos after the Big Bang and helped create the ...

Note: For a definition of unfamiliar terms, see our glossary. The fundamental particles of the universe that physicists have identified—electrons, neutrinos, quarks, and so on—are the "letters" of all ...

Most explanations rely on "dark energy" to explain the Universe's accelerating expansion rate, but a new study takes a different path.

THE partial success which has attended the recent attempts of Einstein and Minkowski to found an electromagnetic system of mechanics has tended to strengthen the popular idea that the solution of ...

On June 25, Timm Wrase awoke in Vienna and groggily scrolled through an online repository of newly posted physics papers. One title startled him into full consciousness. But now, Vafa and his ...

In string theory, a paradigm shift could be imminent. In June, a team of string theorists published a conjecture which sounded revolutionary: String theory is said to be fundamentally incompatible ...
