A team of researchers from Nanjing University, working with two colleagues from the University of Science and Technology of China, has conducted new tests of the chameleon theory and report a failure to find any evidence ...
The Instituto de Astrofísica de Canarias (IAC) led the development of a new numerical procedure to reproduce the intergalactic medium obtained from a cosmological simulation of 100,000 hours of computation using big data ...

A trio of astrophysicists, two from Princeton, the other from New York University, has calculated estimations on how soon the universe could collapse if theories regarding dark energy as having quintessence are correct. In ...
A team of scientists has predicted the science return from one of NASA's Nancy Grace Roman Space Telescope's groundbreaking planned surveys, which will analyze millions of galaxies strewn across space and time. The mission's ...

The laws of physics underlying everyday life are, at one level of description, completely known, and can be summarized in a single elegant—if quite complex—equation. That's the claim physicist Sean Carroll, an SFI Fractal ...
