The cracks in cosmology were supposed to take a while to appear. But when the James Webb Space Telescope (JWST) opened its lens last spring, extremely distant yet very bright galaxies immediately ...

What existed before the big bang? What is the nature of time? Is our universe one of many? On the big questions science cannot (yet?) answer, a new crop of philosophers are trying to provide answers.

Thirty years ago Alan H. Guth, then a struggling physics postdoc at the Stanford Linear Accelerator Center, gave a series of seminars in which he introduced “inflation” into the lexicon of cosmology.

Cosmology must seem odd to scientists in other fields. More and more accurate data about the distant Universe are being generated by high-tech observational techniques, giving rise to an era of ...

Cosmology is one of the most creative and bizarre areas of science. Explore some of the strangest ideas in this exclusive feature Could our universe be a membrane floating in higher dimensional space, ...

Dr. Zuyu Zhao, Executive Vice President and Principle Scientist at Janis Research, talks to AZoM about the importance of Ultra Low Temperature research and its use in cosmology. How low do ...

The hot and cold spots from the hemispheres of the sky, as they appear in the CMB. The data underlying these maps encodes a tremendous amount of information about the early Universe, including what it ...

Clusters of hundreds or thousands of galaxies sit at the intersections of giant, crisscrossing filaments of matter that form the tapestry of the cosmos. As gravity pulls everything in each galaxy ...

Three papers published in JCAP presenting the sixth and final data release of the Atacama Cosmology Telescope offer a new map of the “infant” Universe, confirm the “Hubble tension,” and rule out a set ...

In simulations, however, visible matter does not supply enough gravity to create the structure we see: it has to be helped out by some form of dark matter. More evidence for the dark stuff comes ...
