"The Black Hole Paradox" --New Theory Says Soon After Big Bang, Black Holes Lit Up the Universe
Soon after the Big Bang, the universe went completely dark. The intense, seminal event that created the cosmos churned up so much hot, thick gas that light was completely trapped. Much later—perhaps a...
New Scientific Study Suggests Advanced Alien civilizations could have existed Before the Big Bang
Professor Roger Penrose from the University of Oxford (UK) and Vaha Gurzadian from the Center for Cosmology and Astrophysics, Alikhanian National Laboratory and Yerevan State University, Yerevan, Arme...
Finally Some Answers On Dark Energy, The Mysterious Master Of The Universe
The world's fourth-largest optical telescope has a new experiment coming online. Unless you’re an astrophysicist, you probably don’t sit around thinking about dark energy all that often. That's unders...
Hubble Spots Mother Lode Of 250 Ancient Tiny Galaxies
Scientists are getting a peek into the early days after the big bang thanks to Hubble's discovery of a large collection of dwarf galaxies. The Hubble Space Telescope has been in operation since 1990 a...
Latest Experiment At Large Hadron Collider Reports First Results
After a two-year hiatus, the Large Hadron Collider, the largest and most powerful particle accelerator in the world, began its second run of experiments in June, smashing together subatomic particles ...
New 'Stealth Dark Matter' Theory May Explain Mystery Of The Universe's Missing Mass
Lawrence Livermore National Laboratory (LLNL) scientists have come up with a new theory that may identify why dark matter has evaded direct detection in Earth-based experiments. A group of national pa...
Farthest Galaxy Detected
Caltech researchers have reported the detection of the farthest object yet, galaxy EGS8p7. At more than 13.2 billion years old, it provides a fascinating glimpse of the very early universe, just 600,0...
The Case For Spectral Distortions In The Cosmic Microwave Background
Half a century ago, astronomers got their first look at the infant universe: a haze of soft light that suffused the entire sky. This cosmic microwave background (CMB) radiation seemed to indicate that...
New Record! Astronomers Nail Down Distance To The Earliest Galaxy Yet
A team of astronomers peering deep into the heavens has discovered the earliest, most distant galaxy yet, spotted a record-breaking 670 million years from the big bang. The findings, described in Astr...
Water could have been abundant in the first billion years
How soon after the Big Bang could water have existed? Not right away, because water molecules contain oxygen and oxygen had to be formed in the first stars. Then that oxygen had to disperse and unite ...
Astrophysicists Draw Most Comprehensive Map Of The Universe
Astrophysicists have created a 3D map of the universe that spans nearly two billion light years and is the most complete picture of our cosmic neighbourhood to date. The spherical map of galaxy superc...
Universe's Expansion May Be Slower Than Previously Believed, Study Finds
According to a team of astrophysicists led by the University of Arizona, the universe might be expanding at a slower rate than previously believed – or so their findings, which were published as two p...
Monster black hole born shortly after big bang
Cosmic beast munched matter at an unprecedented rate. All galaxies are thought to have supermassive black holes at their center. These start out small—with masses equivalent to between 100 and 100,000...
Taking Stock of the Big Bang Theory of Inflation
Support remains strong for the theory of cosmic inflation even as critics highlight its shortcomings as an explanation for how and why the universe began.

Big Bang - Before the Big Bang
Things are not smooth out in our universe, with clumps of matter we call stars and galaxies drifting through space. Scientists talk through their theories on...
Big Bang
The Big Bang theory is the prevailing cosmological model for the earliest known periods of the universe and its subsequent large-scale evolution. It states that the Universe was in a very high density...

Baryogenesis
In physical cosmology, baryogenesis is the generic term for the hypothetical physical processes that produced an asymmetry (imbalance) between baryons and antibaryons produced in the very early univer...
Initial singularity
The initial singularity was the gravitational singularity of infinite density thought to have contained all of the mass and spacetime of the Universe before quantum fluctuations caused it to rapidly e...
