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.....»»
Cutting-Edge Cosmic Microwave Background Observatory Hits South Pole Stumbling Block

Daily Telescope: Black holes have been merging for a long, long time
Webb wows us again. Enlarge / Scientists have determined the system to be evidence of an ongoing merger of two galaxies and their massive black holes when the Universe was only 740 million years old. (credit: ESA/Webb, NASA, CSA.....»»
Webb detects most distant black hole merger to date
An international team of astronomers have used the NASA/ESA/CSA James Webb Space Telescope to find evidence for an ongoing merger of two galaxies and their massive black holes when the universe was only 740 million years old. This marks the most dist.....»»
Quantum geometry offers new insights into "smart" materials with switchable electric polarity
Quantum theorists at the University of British Columbia have proposed a new approach to studying stacking ferroelectricity—spontaneous electric polarization—in layered, two-dimensional lab-grown materials......»»
Scientists achieve giant Rashba–Dresselhaus spin splitting in 2D chiral metal-organic frameworks
A research team led by Prof. Li Xingxing and academician Yang Jinlong from University of Science and Technology of China (USTC) has developed two-dimensional (2D) chiral metal-organic frameworks as Rashba-Dresselhaus (R-D) semiconductors with large s.....»»
Look, this is the definitive answer to what ‘Air’ in iPad Air really means
Remember when Apple discontinued the original HomePod and still sold the HomePod mini? The question at the time was “mini compared to what?” Apple later revived the HomePod with a second-gen model, restoring balance to the universe. Now the iP.....»»

We need to consider conservation efforts on Mars, say researchers
Astrobiology is the field of science that studies the origins, evolution, distribution, and future of life in the universe. In practice, this means sending robotic missions beyond Earth to analyze the atmospheres, surfaces, and chemistry of extraterr.....»»
Scientists create black arsenic visible infrared photodetectors
In recent years, the exceptional structure and fascinating electrical and optical properties of two-dimensional (2D) layered crystals have attracted widespread attention. Examples of such crystals include graphene, black phosphorus (BP), and transiti.....»»
The universe could be filled with ultralight black holes that can"t die
Primordial black holes are hypothetical objects formed during the earliest moments of the universe. According to the models, they formed from micro-fluctuations in matter density and spacetime to become sand grain-sized mountain-massed black holes......»»
Astronomers observe elusive stellar light surrounding ancient quasars
MIT astronomers have observed the elusive starlight surrounding some of the earliest quasars in the universe. The distant signals, which trace back more than 13 billion years to the universe's infancy, are revealing clues to how the very first black.....»»
Radio astronomers bypass disturbing Earth"s atmosphere with new calibration technique
An international team of researchers led by astronomers from Leiden University (Netherlands) has produced the first sharp radio maps of the universe at low frequencies. Thanks to a new calibration technique, they bypassed the disturbances of the Eart.....»»
