Einstein’s first leap In 1917, two years after completing his theory of general relativity, Albert Einstein built the first ...

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

Our ideas about the universe are based on a century-old simplification known as the cosmological principle. It suggests that when averaged on large scales, the Cosmos is homogeneous and matter is ...

Physicists sometimes come up with crazy stories that sound like science fiction. Some turn out to be true, like how the curvature of space and time described by Einstein was eventually borne out by ...

Kanazawa, Japan - The expansion of the Universe has occupied the minds of astronomers and astrophysicists for decades. Among the cosmological models that have been suggested over the years, Lambda ...

It's hard to get a sense of the scale of the universe from our little corner of it, but scientists realized decades back that the universe is expanding. This naturally led to questions about the ...

Cosmological models with varying fundamental constants explore the possibility that quantities traditionally regarded as immutable—such as the speed of light (c), Newton’s gravitational constant (G) ...

An international team of astronomers has determined that Centaurus A, a massive elliptical galaxy 13 million light-years from Earth, is accompanied by a number of dwarf satellite galaxies orbiting the ...

Conventional cosmology rests on the assumption of large-scale homogeneity and isotropy as enshrined in the Friedmann–Lemaître–Robertson–Walker framework. Inhomogeneous cosmological models relax this ...

A team of researchers from the collaboration Sloan Digital Sky Survey III (SDSS-III) have presented this week the latest results obtained from the map obtained by the consortium with data collected ...
