Earlier this year, the Dark Energy Spectroscopic Instrument (DESI) completed observations that mapped 47 million galaxies across 11 billion light-years, allowing astronomers to better evaluate the large-scale structure of ...
Gravity, the force that attracts objects toward each other, is currently framed by Albert Einstein's theory of general relativity. This framework describes gravity as the curvature of spacetime, the invisible four-dimensional ...
In a recent viewpoint published in Nature Climate Change, six researchers from South America, Asia and Africa examine how glacier retreat in the Andes, Himalayas and other high-altitude regions is reshaping the cultural and ...
Dark matter is often portrayed as a cosmic loner, interacting with itself and the rest of the universe only through gravity. But what if dark matter particles also exert a hidden force on one another?
Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a variety of cosmological and gravitational phenomena. Two renowned examples of these boundaries are ...
Research led by the Tata Institute of Fundamental Research, Mumbai, along with Professor Subir Sarkar from the University of Oxford, questions the widely accepted argument that the expansion rate of the universe is accelerating ...
Just a few hundred million years after the Big Bang, the universe was a dark and simple place. There were no galaxies like the Milky Way, no planets, and no heavy elements such as carbon or oxygen. Instead, vast clouds of ...
A stunningly concentrated and hefty galaxy cluster, from a time in the universe's history when such massive structures aren't expected to have fully formed yet, is challenging cosmic evolution theories. Across a series of ...
Between the mid-1970s and early 1980s, two physicists, Michael Hart and Frank Tipler, published a controversial series of papers arguing that extraterrestrial intelligence didn't exist. As they argued, the likelihood that ...
The European Space Agency (ESA) has officially adopted ARRAKIHS as a scientific mission, confirming the target launch date of 2030. Matthieu Schaller is part of the science team: "I look forward to learning more about the ...
