Cosmologists have long treated black holes and the Big Bang as separate extremes of physics, one swallowing light, the other ...

In 1929, Edwin Hubble discovered from observations of distant galaxies that the Universe was expanding. This baffled astronomers and the public alike. Then in 1998, another wrinkle: Two different ...

Cosmic inflation tries to describe one brief but crucial phase in the Big Bang that launched the universe onto its expansion course. Many textbooks and science educators have attempted to describe the ...

For the first time ever, you can time travel through space to the edge of the visible universe from the comfort of your own home. Johns Hopkins University unveiled a first-of-its-kind map on Thursday ...

Cosmologists are finally beginning to sketch a coherent picture of the universe we cannot see, using exquisitely detailed maps of galaxies, ghostly light and the large scale structure of space itself.

Researchers have long suspected a connection between information and the physical universe, with various paradoxes and thought experiments used to explore how or why information could be encoded in ...

Dark matter is understood to interact “feebly” with the visible universe, but was that always true? Physicists have modeled the inflaton—a theoretical space scientists use to examine the period ...

A few hundred million years after the Big Bang, a thick fog of hydrogen gas shrouded the newborn universe in darkness. Stars had begun to form in the densest clumps, but the surrounding gas muffled ...

Scientists debate whether this object is the brightest in the visible universe, as a new study suggests. By Dennis Overbye Astronomers claimed on Monday that they had discovered what might be the ...

The Universe is big, as Douglas Adams would say. The most distant light we can see is the cosmic microwave background (CMB), which has taken more than 13 billion years to reach us. This marks the edge ...
