The Higgs particle could have ended the universe by now—here"s why we"re still here
Although our universe may seem stable, having existed for a whopping 13.7 billion years, several experiments suggest that it is at risk—walking on the edge of a very dangerous cliff. And it's all down to the instability of a single fundamental part.....»»
An efficient numerical program for studying light scattering at the nanoscale
When light encounters a particle, it interacts with the particle instead of just passing through smoothly. The light waves can get scattered in different directions because of the light-matter interactions......»»
Lopsided galaxies shed light on the speed of dark matter
In new research published in Astronomy & Astrophysics, researchers have figured out how to precisely calculate the forces that affect galaxies in tidal cycles. The next stage is to find galaxies sufficiently lopsided in the universe to study the velo.....»»
NASA helicopter"s mission ends after three years on Mars
NASA's Ingenuity Mars helicopter, which made history by achieving the first powered flight on another world, has officially ended its nearly three-year mission after sustaining rotor damage during its last outing, the space agency said Thursday......»»
After three years on Mars, NASA"s Ingenuity helicopter mission ends
NASA's history-making Ingenuity Mars Helicopter has ended its mission at the Red Planet after surpassing expectations and making dozens more flights than planned. While the helicopter remains upright and in communication with ground controllers, imag.....»»
Webb sees dozens of young quasars in the first billion years of the universe
Within almost every galaxy is a supermassive black hole. Millions, sometimes billions of solar masses are locked within an event horizon of space and time. They can power luminous quasars, drive star formation, and change the evolution of a galaxy. B.....»»
Rare decay of the Higgs boson may point to physics beyond the Standard Model
Particle physicists have detected a novel decay of the Higgs boson for the first time, revealing a slight discrepancy in the predictions of the Standard Model and perhaps pointing to new physics beyond it. The findings are published in the journal Ph.....»»
Tesla profits, margins slip in Q4 as revenue inches higher
The company reported a gross margin of 17.6 percent for the three months ended December, compared with 23.8 percent a year earlier......»»
Microwave detectors and multiplexing: Researchers help astronomers examine the early universe
Perched atop a high plateau in Chile's Atacama Desert, a long-awaited observatory is beginning to take shape: the largest suite of ground-based telescopes devoted to studying the oldest light in the universe: radiation left over from the Big Bang......»»
Thirsty? Water is more common than you think
Water is abundant throughout the entire universe. What water has going for it is that its constituents, hydrogen and oxygen, are also ridiculously common, and those two elements really enjoy bonding with each other. Oxygen has two open slots in its o.....»»
Gravity helps show strong force strength in the proton
The power of gravity is writ large across our visible universe. It can be seen in the lock step of moons as they circle planets; in wandering comets pulled off-course by massive stars; and in the swirl of gigantic galaxies. These awesome displays sho.....»»
Life on Earth uses water as a solvent. What are some other options for life as we don"t know it?
There is a vast menagerie of potentially habitable worlds in the cosmos, which means the universe could be home to a diversity of life beyond what we can imagine. Creatures built on silicon rather than carbon, or organisms that breathe hydrogen inste.....»»
Watch Sierra Space blow up its LIFE habitat in dramatic pressure test
Sierra Space has conducted a pressure test on its LIFE space habitat that ended with a dramatic – though expected – explosion......»»
Tiny worm, giant leap: Discovery of highly specific fatty acid attachment to proteins
In a world where the intricacies of molecular biology often seem as vast and mysterious as the cosmos, a new study delves into the microscopic universe of proteins, unveiling a fascinating aspect of their existence. This revelation could hold profoun.....»»
Astrophysicists offer theoretical proof of traversable wormholes in the expanding universe
The expansion of the universe at some stage of evolution is well described by the Friedmann model. It was derived from general relativity a hundred years ago, but it is still considered one of the most important and relevant cosmological models......»»
Unlocking the secrets of the universe through neutrinoless double beta decay
The discovery that neutrinos have mass was groundbreaking. However, their absolute mass remains unknown. Neutrinoless double beta decay experiments aim to determine whether neutrinos are their own antiparticles and, if so, provide a means to determin.....»»
James Webb Space Telescope: Finally, the edge of the universe and beyond
Launched in 2021 on Christmas Day, the James Webb Space Telescope is the most complex, precise and powerful space observatory ever built......»»
Investigating the role of "random walks" in particle diffusion
Several recent experiments identify unusual patterns in particle diffusion, hinting at some underlying complexity in the process which physicists have yet to discover. Through new analysis published in The European Physical Journal B, Adrian Pacheco-.....»»
Webb reveals that galaxy mergers are the solution to early universe mystery
One of the key missions of the NASA/ESA/CSA James Webb Space Telescope is to probe the early universe. Now, the unmatched resolution and sensitivity of Webb's NIRCam instrument have revealed, for the first time, what lies in the local environment of.....»»
Webb data suggest many early galaxies were long and thin, not disk-like or spherical
Columbia researchers analyzing images from NASA's James Webb Space Telescope have found that galaxies in the early universe are often flat and elongated, like breadsticks—and are rarely round, like balls of pizza dough......»»
Researchers observe the wave-particle duality of two photons
Understanding the nature of quantum objects' behaviors is the premise for a reasonable description of the quantum world. Depending on whether the interference can be produced or not, the quantum object is endowed with dual features of a wave and a pa.....»»
