Nuclear clock experiments set a landmark in timekeeping technology

There are many ways we can keep track of passing seconds. Counting “Mississippi” between numbers works. Monitoring the swing of a pendulum is a little more accurate. Or if you want to get super fancy, use the piezoelectric buzz of electrified quartz.

The Strange “Spacetime Crystal” That Can Suddenly Turn Into a Black Hole

A new mathematical breakthrough sheds light on how tiny black holes could emerge from critical states of spacetime. Black holes are often portrayed as cosmic giants, swallowing stars and shaping entire galaxies. But some of the most intriguing black holes predicted by physics could be far smaller than an atom. For decades, scientists have known [...]

“Bootstrap” physics study claims string theory might be inevitable after all

String theory is perhaps the greatest tragedy of modern science. Mathematically elegant and celebrated savior of divided physics, it is nonetheless crippled by one simple fact – it is utterly untestable.

MIT Engineers Solve a Major Lidar Problem That Has Stumped Researchers for Years

A new MIT-designed lidar chip uses specially engineered antennas to reduce interference and widen the sensor’s field of view. From self-driving cars navigating busy streets to drones surveying disaster zones, lidar has become one of the most important technologies for helping machines perceive the world in three dimensions. By sending out rapid pulses of infrared [...]

New 7-Dimensional Theory May Finally Solve the Black Hole Information Paradox

A new theoretical study suggests that black holes may never completely disappear, potentially offering a way to resolve the long-standing black hole information paradox. One of the biggest unsolved problems in modern physics, known as the “black hole information paradox,” may finally have a compelling solution. The proposed answer could also help explain where the [...]

Breakthrough Technique Reveals Atomic Secrets of Record-Breaking Superconductors

Scientists have achieved a first in studying lanthanum superhydrides, a class of materials that could help unlock superconductivity at much higher temperatures. The dream of transmitting electricity without energy loss has driven decades of superconductivity research. Some of the most promising candidates yet are superhydrides, hydrogen-rich materials that, under immense pressures, have exhibited…

Magnon Breakthrough Could Shrink Quantum Computers to the Size of a Penny

Physicists at the University of Vienna have discovered magnons with lifespans that are one hundred times longer. Magnons are tiny waves of magnetization that move through solid magnetic materials, similar to ripples spreading across water after a stone falls in. Unlike photons, which can move through empty space or optical fibers, magnons travel inside magnetic [...]

Physicists Have Measured “Negative Time” in Bizarre Quantum Experiment

Quantum physicists have uncovered a bizarre phenomenon in which photons appear to spend a “negative” amount of time interacting with atoms before emerging from a cloud of matter. As Homer tells us, Odysseus made an epic journey, against the odds, from Troy to his home in Ithaca. He visited many lands but mostly dwelt with [...]

Earth’s outer core reversed direction in 2010 and scientists may finally know why

Deep beneath the Pacific near the equator, Earth’s outer core now flows east instead of west. Dynamics deeper within our planet’s core may help explain the change and what to expect in the near future.

Physicists Found String Theory Without Even Looking for It

Physicists searching for a better understanding of quantum gravity stumbled upon something unexpected: the defining signatures of string theory. Imagine slicing an apple into smaller and smaller pieces. First you would reach molecules, then atoms, and eventually the subatomic particles inside them, including protons, quarks, and gluons. According to string theory, however, nature may continue…
