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.....»»
XL-Calibur telescope launched to study black holes
Scientists from Washington University in St. Louis have launched a balloon-borne telescope to unlock the secrets of astrophysical black holes and neutron stars, some of the most extreme objects in the universe......»»
We need to consider alternatives to dark matter that better explain cosmological observations
Do constants of nature—the numbers that determine how things behave, like the speed of light—change over time as the universe expands? Does light get a little tired traveling vast cosmic distances? It was believed that dark matter and dark energy.....»»
Webb captures a staggering quasar-galaxy merger in the remote universe
An international research group led by the Italian National Institute for Astrophysics (INAF) and comprising 34 research institutes and universities worldwide utilized the Near-Infrared Spectrograph (NIRSpec) on board the James Webb Space Telescope (.....»»
The influence of peptoid sequence on the mechanisms and kinetics of 2D assembly
Two-dimensional (2D) materials have unique physical and chemical properties and potential for a wide variety of applications. Peptoids, a type of molecule, compose a class of sequence-defined polymers that mimic biological compounds and can self-asse.....»»
Searching for dark matter with the coldest quantum detectors in the world
One of the greatest mysteries of science could be one step closer to being solved. Approximately 80% of the matter in the universe is dark, meaning that it cannot be seen. In fact, dark matter is passing through us constantly—possibly at a rate of.....»»
Mapping the surfaces of MXenes, atom by atom, reveals new potential for the 2D materials
In the decade since their discovery at Drexel University, the family of two-dimensional materials called MXenes has shown a great deal of promise for applications ranging from water desalination and energy storage to electromagnetic shielding and tel.....»»
Synthesis method for 1D segmented heteronanostructures uses stress-induced axial ordering
One-dimensional segmented heteronanostructures (1D-SHs) are promising candidates in fields such as photoelectrocatalysis (PEC) and thermoelectrics. Currently, the synthesis of 1D-SHs mainly focuses on sulfides and selenides, with relatively less rese.....»»
The universe"s biggest explosions made elements we are composed of, but there"s another mystery source out there
After its "birth" in the Big Bang, the universe consisted mainly of hydrogen and a few helium atoms. These are the lightest elements in the periodic table. More-or-less all elements heavier than helium were produced in the 13.8 billion years between.....»»
Cryovolcanism: Why study it? What can it teach us about finding life beyond Earth?
Universe Today has had the privilege of spending the last several months venturing into a multitude of scientific disciplines, including impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, plane.....»»
Chandra X-ray Observatory"s clear, sharp photos help astrophysicist study energetic black holes
When a star is born or dies, or when any other very energetic phenomenon occurs in the universe, it emits X-rays, which are high-energy light particles that aren't visible to the naked eye. These X-rays are the same kind that doctors use to take pict.....»»
A new Hungarian method may aid protein research
In a paper recently published in Nature Communications, the HUN-REN-ELTE Protein Modeling Research Group (Institute of Chemistry) has laid the foundations for a mathematical method, allowing the computer-assisted comparison of the three-dimensional s.....»»
Starless and forever alone: More "rogue" planets discovered
The Euclid space telescope has discovered seven more rogue planets, shining a light on the dark and lonely worlds floating freely through the universe untethered to any star......»»
The death of Vulcan: Study reveals planet is actually an astronomical illusion caused by stellar activity
A planet thought to orbit the star 40 Eridani A—host to Mr. Spock's fictional home planet, Vulcan, in the "Star Trek" universe—is really a kind of astronomical illusion caused by the pulses and jitters of the star itself, a new study shows......»»
Researchers successfully fabricate NiS ultrafine nanorods with separated symmetry along two directions
Crystal symmetry is a fundamental concept in materials science, playing a crucial role in determining structure-property relationships. Typically, a crystal is a solid composed of structural units that periodically repeat in three-dimensional space,.....»»
One UI 6.1.1 Update May Fix Galaxy S24 Camera Issues
According to leaker Ice Universe, Samsung’s started testing the Galaxy S24 One UI 6.1.1 update ahead of its release this summer. Samsung’s updated the Galaxy S24, Galaxy S24+, and Galaxy S24 Ultra numerous times since launch, but the leak.....»»
Does String Theory Actually Describe the World? AI May Be Able to Tell
Using machine learning, string theorists are finally showing how microscopic configurations of extra dimensions translate into sets of elementary particles—though not yet those of our universe......»»
