After a three-decade search, scientists appear to have found the elusive particle. Its peculiar properties suggest a new era in physics could be about to dawn
Quantum effects may prevent true black holes from forming and give rise instead to dense entities called black stars
Neutrinos, the strangest beasts in the particle zoo, may soon open the way to unexplored realms
Maybe unifying the forces of nature isn't quite as hard as physicists thought it would be
Once viewed as imposing absolute limits on knowledge and technology, quantum theory is now expanding the power of computers and the vistas of the mind
Cosmologists are closing in on the ultimate processes that created and shaped the universe
The largest stars die in explosions more powerful than anyone thought possible—some triggered in part by the production of antimatter
Entanglement, like many quantum effects, violates some of our deepest intuitions about the world. It may also undermine Einstein's special theory of relativity
By adapting a global network of telescopes, astronomers will soon get their first look ever at the dark silhouette of a black hole
Dark matter is not just a puzzle. It is a solution
Maybe not. The observations that led astronomers to deduce its existence could have another explanation: our galaxy lies at the center of a giant cosmic void
The black hole has a troublesome sibling, the naked singularity. Physicists have long thought—hoped—it could never exist. But could it?
Physicists have long sought to find one final theory that would unify all of physics. Instead they may have to settle for several
Bubble chamber photographs reveal the telltale tracks of exotic subatomic particles
Leonard Susskind rebelled as a teen and never stopped. Today he insists that reality may forever be beyond reach of our understanding
What if the smallest bits of matter actually harbor an undiscovered world of particles?
