How to think about a four-dimensional universe
In Einstein's famous theory of relativity the concepts of immutable space and time aren't just put aside, they're explicitly and emphatically rejected. Space and time are now woven into a coexisting fabric. That is to say, we truly live in a four-dim.....»»
New measurements reveal the enormous halos that shroud all galaxies in the universe
Have you ever wanted to make a $150,000 gamble? If you're right, you open a new window to the universe. But if you're wrong, you've just wasted a lot of money and time......»»
Hidden, compact galaxies in the distant universe—searching for the secrets behind the little red dots
Astronomers exploring the faraway universe with the James Webb Space Telescope, NASA's most powerful telescope, have found a class of galaxies that challenges even the most skillful creatures in mimicry—like the mimic octopus. This creature can imp.....»»
AI helps distinguish dark matter from cosmic noise
Dark matter is the invisible force holding the universe together—or so we think. It makes up about 85% of all matter and around 27% of the universe's contents, but since we can't see it directly, we have to study its gravitational effects on galaxi.....»»
Gravitational waves unveil previously unseen properties of neutron stars
A better understanding of the inner workings of neutron stars will lead to a greater knowledge of the dynamics that underpin the workings of the universe and also could help drive future technology, said the University of Illinois Urbana-Champaign ph.....»»

Physicists capture first thickness-dependent transitions in two-dimensional magnetic material
A team of physicists from The University of Hong Kong (HKU), Texas Tech University (TTH), and the University of Michigan (UMich), has made an important discovery in the study of van der Waals (vdW) magnetic materials, a special class of materials wit.....»»
First detection of cross-correlation between cosmic shear and X-ray background enhances baryonic matter understanding
A new study in Physical Review Letters offers the first detection of the cross-correlation between cosmic shear and diffuse X-ray background, helping to understand the distribution of baryonic matter in the universe......»»
How gravitational waves could help detect Star Trek-style warp drive spaceships
How much do we really know about what else is out there in the universe?.....»»
NASA"s mini BurstCube mission detects its first gamma-ray burst
The shoebox-sized BurstCube satellite has observed its first gamma-ray burst, the most powerful kind of explosion in the universe, according to a recent analysis of observations collected over the last several months......»»
Gravitational wave observatories could detect primordial black holes speeding through the solar system
Cosmologists have long hypothesized that the conditions of the early universe could have caused the formation of black holes not long after the Big Bang. These "primordial black holes" have a much wider mass range than those that formed in the later.....»»
85% of the matter in the universe is missing: But scientists are getting closer to finding it
Most of the matter in the universe is missing. Scientists believe around 85% of the matter in the cosmos is made of invisible dark matter, which has only been detected indirectly by its gravitational effects on its surroundings......»»
Spin-controlled generation of a complete polarization set with randomly interleaved plasmonic metasurfaces
Optical metasurfaces are finely crafted two-dimensional artificial nanostructures composed of meticulously designed arrays of ultrathin artificial atoms. These surfaces possess capabilities beyond natural materials, enabling multifunctional control o.....»»
Researchers present a high-dimensional choice model for online retailing
In a new study, researchers developed a model that helps online retailers to more accurately predict customer purchases from a wide range of products in complex online shopping environments, reducing sales forecast errors by 10%–30% compared to tra.....»»
James Webb is explaining the puzzle of some of the earliest galaxies
Webb has been causing bafflement in the field of cosmology. But the problem isn't that the universe is broken - it's that early black holes were playing tricks......»»
NASA"s Roman Space Telescope to investigate galactic fossils
The universe is a dynamic, ever-changing place where galaxies are dancing, merging together, and shifting appearance. Unfortunately, because these changes take millions or billions of years, telescopes can only provide snapshots, squeezed into a huma.....»»
New Horizons spacecraft measurements shed light on the darkness of the universe
Just how dark is deep space? Astronomers may have finally answered this long-standing question by tapping into the capabilities and distant position of NASA's New Horizons spacecraft, by making the most precise, direct measurements ever of the total.....»»
Pioneering research suggests nature of dark matter is more elusive than ever
New results from the world's most sensitive dark matter detector narrow down its characteristics, edging closer to unraveling one of the biggest mysteries of the universe......»»
Dark matter could have helped make supermassive black holes in the early universe
It takes a long time for supermassive black holes, like the one at the center of our Milky Way galaxy, to form. Typically, the birth of a black hole requires a giant star with the mass of at least 50 of our suns to burn out—a process that can take.....»»
What makes a supercluster?
By eye, it's impossible to pick out the exact boundaries of the superclusters, which are among the largest structures in the universe. But that's because they are not defined by their edges, but by the common motion of their components......»»
Experiment sets new record in search for dark matter
Figuring out the nature of dark matter, the invisible substance that makes up most of the mass in our universe, is one of the greatest puzzles in physics. New results from the world's most sensitive dark matter detector, LUX-ZEPLIN (LZ), have narrowe.....»»
