Scientists Discover the First Type of Molecule Formed in the Universe
The first type of molecule that ever formed in the universe has been detected in space for the first time, after decades of searching. Scientists…
What Was The Universe Like Before The Big Bang?
A team of scientists has proposed a powerful new test for inflation, the theory that the universe dramatically expanded in size in a fleeting fraction…
Astronomers Discover the Last of Universe’s Missing Ordinary Matter
Researchers at the University of Colorado Boulder have helped to find the last reservoir of ordinary matter hiding in the universe. Ordinary matter, or “baryons,”…
Stephen Hawking’s Final Theory About The Big Bang
Professor Stephen Hawking’s final theory on the origin of the universe, which he worked on in collaboration with Professor Thomas Hertog from KU Leuven, has…
Scientists Find New Way of Exploring the Afterglow From the Big Bang
Researchers have developed a new way to improve our knowledge of the Big Bang by measuring radiation from its afterglow, called the cosmic microwave background…
Astronomers Detect Ancient Stars That Formed From Smoldering Embers of the Big Bang
For the first time, astronomers have detected a signal from stars emerging in the early universe. Using a radio antenna not much larger than a…
Physicist Challenges the Idea That Time Had a Beginning
“I believe the Big Bang never happened,” said Juliano César Silva Neves, a physicist at the University of Campinas’s Mathematics, Statistics & Scientific Computation Institute…
Scientists Provide a Theory on How the Universe Became Filled with Light
After observing a nearby galaxy from which ultraviolet light is escaping, astronomers hypothesize that black holes may have punctured darkened galaxies and allowed light to…
Scientists Propose a New Method to Probe the Evolutionary History of the Universe
New research from the Harvard-Smithsonian Center for Astrophysics suggests that oscillating heavy particles generated “clocks” in the primordial universe that could be used to determine…
Astronomers Study the Interstellar Medium a Billion Years After the Big Bang
In a newly published study astronomers measured the emission from ionized carbon in seventeen young galaxies, revealing a good measure of the rate of star…
Study Investigates Interaction between the Higgs Particle and Gravity
A newly published study details how the spacetime curvature provided the stability needed for the universe to survive after the Big Bang. Studies of the…
Higgs Boson May Explain the Earliest Expansion of the Universe
In a newly published study, physicists propose that the Higgs boson, which was recently confirmed to be the origin of mass, may also be responsible…
Our Universe May Have Emerged from a Black Hole in a Higher Dimensional Universe
New research from theoretical physicists at the Perimeter Institute proposes that our universe may have emerged from a black hole in a higher-dimensional universe. The…
Astrophysicists Challenge the Cosmological Model
By comparing the predictions of state-of-the-art supercomputer simulations with the results of sophisticated statistical analyses of the cosmic background radiation, two independent studies are challenging…
Physicists Successfully Simulate Evolution of the Early Universe
Using ultracold cesium atoms in a vacuum chamber, scientists have successfully simulated the evolution of the early universe. Physicists have reproduced a pattern resembling the…
Researchers Use New CMB Data to Analyze the First Hundred Thousand Years of Our Universe
Using cosmic microwave background radiation data from Planck and WMAP9, researchers look back through time at the first 100 years to 300,000 years after the…
Keck Observatory Observations Strengthen Big Bang Theory
Using Keck observations of ancient stars and models of their atmospheres, researchers have shown that there is no conflict between their lithium-6 and lithium-7 content…
