Oxford physicists create network of quantum-entangled atomic clocks

University of Oxford physicists have linked two atomic clocks through quantum entanglement for the first time. The feat can help make these clocks so precise that they begin to approach the fundamental limit of precision set by quantum mechanics.

The end of everything: 5 ways the universe could be destroyed

Everything has to end eventually – including the universe itself. It might be hard to imagine a catastrophe big enough to affect the entirety of existence, but here are some of the leading hypotheses about how the universe could end, and when.

A brief history of the Higgs boson, the Holy Grail of physics

This month marks the 10th anniversary of the discovery of the Higgs boson. But what exactly is this particle, and why is it so important? What has it taught us in the last decade – and more importantly, what could it teach us in the next decade?

“Quantum flute” gets light moving in way never seen before

Scientists have created a “quantum flute” that can coax photons to move in sync and interact with each other, which they almost never do in nature. The device could help improve future quantum computer designs.

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.
