Quantum computers, systems that process information leveraging quantum mechanical effects, could outperform classical computers on some computationally demanding tasks. Despite their potential, as the size of quantum computers increases, reliably describing and measuring the states driving their functioning becomes increasingly difficult.

Neptune is the solar system’s most distant planet, a cold, blue ice giant sitting nearly 30 times further from the sun than Earth. At that remote distance, temperatures plunge to nearly minus 200 degrees Celsius and a single year lasts 165 Earth years. Yet despite its isolation, Neptune is a world whipped by the fastest […]
More than 10,000 Starlink satellites currently orbit Earth. We see them crawling across dark skies, no matter how remote our location, and streaking through images from research telescopes.

Quantum technologies, devices that can process, store, or detect information leveraging quantum mechanical effects, could outperform classical devices in some tasks or scenarios. Despite their potential, verifying that these devices work correctly and truly realize desired quantum states can be challenging, particularly when they cannot be fully examined or inspected.

One of the things astronomers find when they look around at galaxies is a correlation between a galaxy’s mass and the mass of its supermassive black hole. Contrary to popular belief, these SMBH don’t anchor their galaxies; they make up only a small portion of a galaxy’s mass. In local galaxies, the ratio of SMBH […]
General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from rotational frame dragging to the radiation of gravitational waves. But there is reason to believe that it is not the final say on the nature […]
Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests that the universe’s rapid early expansion could have arisen naturally from a deeper, more complete theory of quantum gravity. The paper, […]
When an invisible entity making up 85% of the universe’s mass stumps the greatest scientific minds of our time, awe is an understandable response.

Researchers at NYU Abu Dhabi have discovered new large-scale waves moving deep inside the sun, driven by magnetic fields far below the surface. These waves provide a window into parts of the sun that are otherwise inaccessible, giving scientists a new tool to study how its magnetic field is formed and evolves over time.

A recent study published in Physical Review Letters reveals that many widely used signatures of criticality in brain data may be statistical artifacts. They propose a more robust framework that, when applied to whole-brain fMRI data, confirms the brain operates near, but not exactly at, a critical point.

With a new lab-based experiment, researchers in the UK and France have recreated the characteristic cascades of energy and angular momentum that underpin key features of Earth’s atmosphere. Reporting in Physical Review Letters, a team led by Peter Read at the University of Oxford has gained fresh insights into how energy fluctuations in turbulent flows […]
When we think of asteroids, we almost immediately think of giant rocks bouncing around like the iconic chase scene in “The Empire Strikes Back,” and we often hear how they are remnants from the birth of the solar system. While the asteroids that comprise the Main Asteroid Belt of our solar system are not only […]
Trump signed an executive order in February 2026 directing all federal agencies to release classified files on alien life, UAP, and UFOs. Weeks later, a UFO-linked Air Force general and NASA materials scientist vanished under mysterious circumstances. Coincidence — or cover-up?
The post Trump Orders UFO Files Declassified — Then Two Scientists With Alien […]
