Phys.org / Yes, the universe can expand faster than light
An expanding universe complicates this picture just a little bit, because the universe absolutely refuses to be straightforward. Objects are still emitting light, and that light takes time to travel from them over to here, ...
Medical Xpress / Remember to give thanks to yourself during the holidays and beyond
While reflecting on what we're thankful for during the holiday season, we often focus on the external: the company of loved ones. The nourishment of a shared meal. The homes in which we gather.
Phys.org / Is the universe Infinite?
The surface of Earth is finite. We can measure it. If it was expanding, then its size would grow with time. And once again, good ol' Earth helps us understand what the universe might be doing beyond our observable horizon.
Phys.org / Consciousness as the foundation: New theory addresses nature of reality
Consciousness is fundamental; only thereafter do time, space and matter arise. This is the starting point for a new theoretical model of the nature of reality, presented by Maria Strømme, Professor of Materials Science at ...
Phys.org / Examining why some species developed consciousness while others remained non-conscious
What is the evolutionary advantage of our consciousness? And what can we learn about this from observing birds? Researchers at Ruhr University Bochum published two articles on this topic.
Phys.org / Entanglement-enhanced optical lattice clock achieves unprecedented precision
Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference known as optical lattice.
Phys.org / Ambitious plan to store CO₂ beneath the North Sea set to start operations
Appearing first as a dot on the horizon, the remote Nini oil field on Europe's rugged North Sea slowly comes into view from a helicopter.
Phys.org / 'Truly severe' floods overwhelm Southeast Asia
Authorities across Indonesia, Thailand and Malaysia worked on Thursday to reach residents trapped in floods that have killed dozens of people across the region in recent days.
Phys.org / Physicist delineates limits on the precision of quantum thermal machines
Quantum thermal machines are devices that leverage quantum mechanical effects to convert energy into useful work or cooling, similarly to traditional heat engines or refrigerators. Thermodynamics theory suggests that increasing ...
Phys.org / Scientists warn mountain climate change is accelerating faster than predicted, putting billions of people at risk
Mountains worldwide are experiencing climate change more intensely than lowland areas, with potentially devastating consequences for billions of people who live in and/or depend on these regions, according to a major global ...
Phys.org / Astronomers capture an exceptional gamma-ray flare from a blazar
Astronomers have performed very long baseline interferometry (VLBI) observations of a gamma-ray loud blazar known as TXS 2013+370. The observations, posted November 19 on the arXiv preprint server, resulted in the detection ...
Tech Xplore / New insight into why LLMs are not great at cracking passwords
Large language models (LLMs), such as the model underpinning the functioning of OpenAI's conversational platform ChatGPT, have proved to perform well on various language-related and coding tasks. Some computer scientists ...
