Startling discovery threatens to upend Standard Model of particle physics

A collaboration of physicists has made the most precise measurement of the mass of the W boson. The new measurement of this key particle differs drastically from the Standard Model's predictions– and it may unravel physics as we know it.

Firing lasers at the Moon to detect early-universe gravitational waves

A team of European researchers has suggested that the Moon’s orbit could be used as a gigantic detector for gravitational waves. These waves, much smaller than those that existing detectors can pick up, could originate from the early universe.

Physicists measure gravitational time warp to within one millimeter

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on Earth tick slower than those in space. Now researchers have measured time passing at different speeds across just one millimeter, the smallest distance yet.

“Quantum tornadoes” mark crossover from classical to quantum physics

The universe is governed by two sets of seemingly incompatible laws of physics – classical and quantum physics. MIT physicists have now observed the moment atoms switch from one to the other, as they form intriguing “quantum tornadoes.”

Is the universe’s dark matter hiding in primordial black holes?

A new model by a team of scientists led by Yale University suggests that the ever elusive dark matter that has so far escaped the detection of scientists may be trapped inside primordial black holes left over after the Big Bang.

Harvard scientists observe new state of matter, a quantum spin liquid

An exotic state of matter originally hypothesized almost 50 years ago has been observed for the first time. Created by Harvard researchers, this material called quantum spin liquid could eventually help improve quantum computers.

Lifetime of Higgs boson measured to within septillionths of a second

CERN physicists have measured the life of the Higgs boson with greater accuracy than ever before. Since the legendary particle only lives for a tiny fraction a second, the scientists came up with a creative workaround to calculate the new figure.

How the universe’s expansion may have stopped dark matter taking over

How did the universe end up with exactly the amount of dark matter needed? A new model suggests dark matter particles in the early universe converted regular matter into dark matter exponentially, before being slowed by the expansion of the universe.

The antimatter enigma: What is it and why didn’t it destroy the universe?

Normal matter has an “evil twin” that annihilates on contact, and despite decades of study antimatter remains very mysterious. So what actually is it? Where is it? Why is it important to understand? And why hasn’t it already destroyed the universe?

Strange supersolid state of matter created in new dimension

There are many exotic states of matter besides the basics of solid, liquid, gas and plasma. One of these, known as a supersolid, was confirmed a few years ago, and now University of Innsbruck scientists have created it in a new two-dimensional form.
