Our universe is known to be remarkably homogeneous and isotropic. This essentially means that matter is distributed evenly ...

A recent study in the journal Nature carries cosmos-quaking implications for our understanding of the universe—except a new ...

For nearly a century, astronomers have known that the universe is expanding. In the late 1990s, two independent teams, the ...

Some of the hardest questions in cosmology begin where the usual math gives up. Push Einstein’s theory far enough back toward the Big Bang, and the equations run into a singularity, a point where ...

A study based on 47 million galaxies found that the cosmic web retains patterns on enormous scales, which could force a ...

For most of modern cosmology, scientists have worked with a surprisingly simple assumption: the mysterious force driving the universe's accelerating expansion has remained unchanged throughout cosmic ...

The James Webb Space Telescope (JWST) is the largest and most powerful space telescope built to date. Since it was launched in December 2021 it has provided groundbreaking insights. These include ...

For the past few years, a series of controversies have rocked the well-established field of cosmology. In a nutshell, the predictions of the standard model of the universe appear to be at odds with ...

The Rediff Special / Carl Sagan 'Hindu cosmology's time-scale for the universe is in consonance with modern science' Carl ...

Astronomers have assumed for decades that the Universe is expanding at the same rate in all directions. A new study based on data from ESA’s XMM-Newton, NASA’s Chandra and the German-led ROSAT X-ray ...

Modern cosmology rests on a simple assumption: if we look on large enough scales, matter should be distributed evenly, with no preferred direction within the cosmos. This is known as the cosmological ...
