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 mass to galaxy mass is about 0.1%–0.5%.
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 of space and time.
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, “Ultraviolet completion of the Big Bang in quadratic gravity,” appears in Physical Review Letters.
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.
Chief Jim McDonnell found two officers justified in using deadly force against Gillian Lauren, but the Police Commission concluded they made serious tactical mistakes
The envelope will hold essential documents and include printed guidance for drivers and responding officers on how to communicate during a traffic stop
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 are linked to their size, while also uncovering behaviors that current atmospheric models can’t yet explain.
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 spread far apart from one another, they are also not all made of rock. One asteroid approximately the size of the state of Massachusetts called 16 Psyche is made of metal, which planetary scientists hypothesize could be the remnants of a protoplanet’s core that didn’t build into a full-fledged planet. But how did such a unique asteroid form?
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 Secrets Vanish Without a Trace appeared first on Infinity Explorers. Video shows the Onondaga County Sheriff’s department’s Air One helicopter hovering just above the water as a deputy pulls the dog from the near-freezing waters
The Independence Police Department announced it had recovered five dolls that were potentially contaminated by fentanyl
In a development that could shift our basic understanding of fluid mechanics, researchers from Drexel University have reported that, given the right circumstances, it is possible to induce a simple liquid to fracture like a solid object. Recently published in the journal Physical Review Letters, the research shows how viscous liquids can suddenly break if stretched with enough force.
The astronauts set to become the first lunar visitors in more than half a century arrived at their launch site Friday, joining the towering rocket that stands poised to blast off next week and send them around the moon.
