Gravitational waves and the geometry of spacetime
When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory of relativity, and describes how planets, stars,.....»»
Using sound waves, scientists develop findings that challenge standard theories of solar convection
A team of solar physicists at NYU Abu Dhabi's Center for Astrophysics and Space Science (CASS), led by Research Scientist Chris S. Hanson, Ph.D., has revealed the interior structure of the sun's supergranules, a flow structure that transports heat fr.....»»
New research challenges black holes as dark matter explanation
The gravitational wave detectors LIGO and Virgo have detected a population of massive black holes whose origin is one of the biggest mysteries in modern astronomy. According to one hypothesis, these objects may have formed in the very early universe.....»»
What Came Before the Big Bang?
By studying the geometry of model space-times, researchers offer alternative views of the universe’s first moments......»»
Everything’s About to Hell of a Lot More Expensive Due to Climate Change
Intensifying hurricanes, floods, and heat waves are wreaking havoc across the country—and on all of our bank accounts......»»
The design of a photonic alloy with topological properties
Photonic alloys, alloy-like materials combining two or more photonic crystals, are promising candidates for the development of structures that control the propagation of electromagnetic waves, also known as waveguides. Despite their potential, these.....»»
What"s a heat dome? Here"s why so much of the US is broiling this week
With much of the Midwest and the Northeast broiling—or about to broil—in extreme summer heat this week, meteorologists are talking about heat waves and heat domes......»»
Antarctic cold spells shatter records amid global heat waves in late winter 2023
While 2023 is noted for breaking global temperature records (State of the Global Climate 2023), the year also brought an unexpected twist with extreme cold events in Antarctica. A new study published in Advances in Atmospheric Sciences reveals the su.....»»
Is there anybody out there? NATO hones Arctic subs" sonar skills
In the icy waters of the Arctic, NATO scientists are dissecting sound waves to improve the West's ability to track Russian submarines, as global warming alters acoustics underwater......»»
Sea swamps Bangladesh at one of world"s fastest rates
After cyclone gales tore down his home in 2007, Bangladeshi fisherman Abdul Aziz packed up what was left of his belongings and moved about half a kilometer inland, further away from storm surge waves......»»
Marine heat waves devastate red gorgonians in the Medes Islands: Study
The increase in the frequency and intensity of marine heat waves in recent decades is one of the effects of global climate change. A study by the University of Barcelona, published in the Journal of Animal Ecology, shows that the extreme heat wave of.....»»
Einstein Telescope could launch a new era in astronomy
It's still just a plan, but a new telescope could soon be measuring gravitational waves. Gravitational waves are something like the sound waves of the universe. They are created, for example, when black holes or neutron stars collide......»»
New theory links quantum geometry to electron-phonon coupling
A new study published in Nature Physics introduces a theory of electron-phonon coupling that is affected by the quantum geometry of the electronic wavefunctions......»»
Humanitarian organizations showed flexibility and grit during COVID supply chain disruptions, study finds
When the COVID-19 pandemic hit, it sent shock waves across global supply chains. But manufacturers and other businesses weren't the only ones hit hard: local and international aid organizations, tasked with providing humanitarian assistance during ti.....»»
Study finds ocean warming pushes giant Atlantic bluefin northwards
A new study led by Irish scientists has found giant Atlantic bluefin tuna are moving further north in response to marine heat waves off the Irish coast......»»
Nonreciprocal quantum batteries exhibit remarkable capacities and efficiency
In physics, nonreciprocity occurs when a system's response varies depending on the direction in which waves or signals are propagating within it. This asymmetry arises from a break in so-called time-reversal symmetry, which essentially means that a s.....»»
Scientists record Earth"s radio waves from the Moon
On Feb. 22, a lunar lander named Odysseus touched down near the Moon's South Pole and popped out four antennas to record radio waves around the surface—a moment University of Colorado Boulder astrophysicist Jack Burns hails as the "dawn of radio as.....»»
Researcher suggests that gravity can exist without mass, mitigating the need for hypothetical dark matter
Dark matter is a hypothetical form of matter that is implied by gravitational effects that can't be explained by general relativity unless more matter is present in the universe than can be seen. It remains virtually as mysterious as it was nearly a.....»»
Cutting-edge mathematics provides new tool for particle collision puzzle
Scientists have used computational algebraic geometry to study predictions for particle physics experiments, such as those at the Large Hadron Collider (LHC), which first detected the Higgs particle in 2012......»»
Mystery object waits nearly an hour between radio bursts
Unlike earlier object, the new source's pulses of radio waves are erratic. Enlarge / A slowly rotating neutron star is still our best guess as to the source of the mystery signals. (credit: Nazarii Neshcherenskyi) Roughl.....»»
