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.....»»
Astronomers only knew of a single binary Cepheid system—they just found nine more
Measuring the distance to far away objects in space can be tricky. We don't even know the precise distance to even our closest neighbors in the universe—the Small and Large Magellanic Clouds. But, we're starting to get to the tools to measure it. O.....»»
Cosmochemistry: Why study it? What can it teach us about finding life beyond Earth?
Universe Today has had some fantastic discussions with researchers on the importance of studying impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, and planetary geophysics, and how these diver.....»»
10 Stranger Things spinoffs we’d like to see after season 5
Since Netflix plans to expand the Stranger Things universe after season 5, they should consider these spinoff ideas that fans would love to see......»»
Construction of dual heterogeneous interface between zigzag-like Mo-MXene nanofibers and small CoNi@NC nanoparticles
Two-dimensional transition metal carbides (MXene) possess attractive conductivity and abundant surface functional groups, providing immense potential in the field of electromagnetic wave (EMW) absorption. However, high conductivity and spontaneous ag.....»»
"Dark stars": Dark matter may form exploding stars, and observing the damage could help reveal what it"s made of
Dark matter is a ghostly substance that astronomers have failed to detect for decades, yet which we know has an enormous influence on normal matter in the universe, such as stars and galaxies. Through the massive gravitational pull it exerts on galax.....»»
NASA"s tiny BurstCube mission launches to study cosmic blasts
NASA's BurstCube, a shoebox-sized satellite designed to study the universe's most powerful explosions, is on its way to the International Space Station......»»
Astronomers find evidence that blue supergiant stars can be formed by the merger of two stars
An international piece of research, led by the Instituto de Astrofísica de Canarias (IAC) has found clues to the nature of some of the brightest and hottest stars in our universe, called blue supergiants. Although these stars are commonly observed,.....»»
Research team introduces superaerophobic three-dimensional nickel catalysts for accelerated water electrolysis
Water electrolysis process is a system that produces hydrogen by electrolyzing water. It is an eco-friendly technology that can produce hydrogen fuel, a future energy source, without emitting environmental pollutants, but its limitations include low.....»»
Unveiling the formation of the first galaxies
Utilizing high-resolution three-dimensional radiation hydrodynamics simulations and a detailed supernova physics model run on supercomputers, a research team led by Dr. Ke-Jung Chen from the Institute of Astronomy and Astrophysics, Academia Sinica (A.....»»
Scientists find one of the most ancient stars that formed in another galaxy
The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your ve.....»»
Study demonstrates spontaneous self-organization of microdroplets through quasi one-dimensional confinement
Polymer systems composed of multiple components can spontaneously induce emulsion or microdroplets by mechanical mixing, as an intermediate state of macroscopic phase separation. Unfortunately, the size of generated droplets is nonuniform and their s.....»»
Research team establishes synthetic dimension dynamics to manipulate light
In the realm of physics, synthetic dimensions (SDs) have emerged as one of the frontiers of active research, offering a pathway to explore phenomena in higher-dimensional spaces, beyond our conventional 3D geometrical space. The concept has garnered.....»»
Planetary geophysics: What is it? What can it teach us about finding life beyond Earth?
Universe Today has examined the importance of studying impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, and planetary atmospheres, and how these intriguing scientific disciplines can help scientists and the public.....»»
The mystery of consciousness shows there may be a limit to what science alone can achieve
The progress of science in the last 400 years is mind blowing. Who would have thought we'd be able to trace the history of our universe to its origins 14 billion years ago? Science has increased the length and the quality of our lives, and the techno.....»»
Largest-ever map of universe"s active supermassive black holes released
Astronomers have charted the largest-ever volume of the universe with a new map of active supermassive black holes living at the centers of galaxies. Called quasars, the gas-gobbling black holes are, ironically, some of the universe's brightest objec.....»»
The cosmic neutrino background would tell us plenty about the universe, says researcher
Readers of Universe Today are probably already familiar with the concept of the cosmic microwave background (CMB). Its serendipitous discovery by a pair of radio astronomers at Bell Labs is the stuff of astronomical legend. Over the past decades, it.....»»
The top 5 astronomical discoveries of all time (so far)
From Eratosthenes' circumference to black holes, we've learned a lot about the cosmos. Enlarge (credit: Aurich Lawson | Getty Images) We’ve managed to discover quite a lot about our Universe from our relatively limited.....»»
Photon-like electrons in a four-dimensional world discovered in a real material
Dirac electrons were predicted by P. Dirac and discovered by A. Geim, both of whom were awarded the Nobel Prize in Physics in 1933 and in 2010, respectively. Dirac electrons behave like photons rather than electrons, for they are considered to have n.....»»
Astronomers propose a 50-meter submillimeter telescope
Some parts of the universe only reveal important details when observed in radio waves. That explains why we have ALMA, the Atacama Large Millimeter–submillimeter Array, a collection of 7-meter and 12-meter radio telescopes that work together as an.....»»
AI for astrophysics: Algorithms help chart the origins of heavy elements
The origin of heavy elements in our universe is theorized to be the result of neutron star collisions, which produce conditions hot and dense enough for free neutrons to merge with atomic nuclei and form new elements in a split-second window of time......»»
