Within the physical Universe, matter behaves in ways that are well described ... Determining some aspects of the messy ...

These are the questions we're talking about when we refer to the geometry of the universe. We measure the geometry of the universe by measuring the average density of matter in space and comparing ...

Introduction to Riemannian geometry. Riemannian connections, curvature and geodesics. Applications to submanifolds and to the connection between topology and curvature. The course aims to give a ...

Since the differential stretching of light results from our calibration of time and distance rather than from a speeding universe, dark energy is not required in this paradigm. Time passes quicker in ...

Strange "right-handed" neutrinos may be responsible for all the matter in the universe, according to new research.

The Webb telescope — a scientific collaboration between NASA, ESA, and the Canadian Space Agency — is designed to peer into ...

At Argonne National Laboratory, scientists have leveraged the Frontier supercomputer to create an unprecedented simulation of the universe, encompassing a span of 10 billion light years and ...

Astronomers have detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery is the most distant ...
