SILVER SPRING, Md., July 6, 2011 /PRNewswire/ --There is no more all-encompassing source of mystery than the universe. Since the dawn of humanity, its vastness has elicited endless wonder and questions that have consumed mankind's intellect and imagination. This summer, SCIENCE welcomes back Professor Brian Cox, the physicist whom the Los Angeles Times affectionately calls "the nerd who is cooler than you," for the four-part series WONDERS OF THE UNIVERSE. Expanding on the promise of...

MINNEAPOLIS, May 17, 2011 /PRNewswire/ -- Who Is Your Creator released The 'Something from Nothing' Universe, which is an open-access video that chronicles the way Big Bang followers are forced to fall back on supernatural phenomena for the origin of the universe. Professor Stephen Hawking confirms that, "Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe...

One trillion years from now, an alien astronomer in our galaxy will have a difficult time figuring out how the universe began. They won't have the evidence that we enjoy today. Edwin Hubble made the first observations in support of the Big Bang model. He showed that galaxies are rushing away from each other due to the universe's expansion. More recently, astronomers discovered a pervasive afterglow from the Big Bang, known as the cosmic microwave background, left over from the universe's...

Seven years ago Northwestern University physicist Adilson E. Motter conjectured that the expansion of the universe at the time of the big bang was highly chaotic. Now he and a colleague have proven it using rigorous mathematical arguments. The study, published by the journal Communications in Mathematical Physics, reports not only that chaos is absolute but also the mathematical tools that can be used to detect it. When applied to the most accepted model for the evolution of the universe,...

New dark energy model includes cosmological phase transition Imagine a time when the entire universe froze. According to a new model for dark energy, that is essentially what happened about 11.5 billion years ago, when the universe was a quarter of the size it is today. The model, published online May 6 in the journal Physical Review D, was developed by Research Associate Sourish Dutta and Professor of Physics Robert Scherrer at Vanderbilt University, working with Professor of Physics Stephen...

Book addresses evolution and cosmic reincarnation, biblical literature in light of modern scholarship, social and economic issues SPRING HILL, Fla., Jan. 7 /PRNewswire/ -- This new book is destined to inspire profound thought among scientists and laymen alike. A truly revolutionary work, "Revelations" is centered upon such fundamental issues as evolution and reincarnation - with emphasis upon the purpose behind creation - and should interest many readers. Of headline importance, this book...

Earth's location in the Universe is utterly unremarkable, despite recent theories that propose toppling a foundation of modern cosmology, according to a team of University of British Columbia researchers. Polish astronomer Nicolaus Copernicus's 1543 book, On the Revolutions of the Heavenly Spheres, moved Earth from being the centre of the Universe to just another planet orbiting the Sun. Since then, astronomers have extended the idea and formed the Copernican Principle, which says that our...

U.S. astronomers say they have, for the first time, clearly observed the effects of dark energy on the most massive collapsed objects in the universe. National Aeronautics and Space Administration astronomers using the agency's Chandra X-ray Observatory tracked how dark energy has stifled the growth of galaxy clusters. Combining that information with previous studies, scientists say they have obtained the best clues yet about what dark energy is and what the destiny of the universe might be....

Although we may believe humans know a lot about the Universe, there are still a lot of phenomena to be explained. A team of cosmologists from the University of the Basque Country are searching for the model that best explains the evolution of the Universe. We usually have an image of scientists who study the Universe doing so peering through a telescope. And, effectively, this is what astrophysicists do: gather data about the observable phenomena of the Universe. However, in order to...

By Siegfried, Tom One of the enduring strengths of Science News is its scope. Its pages are open to all fields of science and their subspecialties, to all the realms of human inquiry into the natural (and artificial) world, whether physical, biological or social. Of course, carving all that up into meaningful categories for labeling magazine pages isn't simple. The old 19th century disciplinary divisions don't really work so well in the current interdisciplinary era. So our pages use a...

Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies. Credit: NASA/Wikipedia What is Cosmology? I once commented to an acquaintance that I was fascinated by the field of Cosmology, and mused that if I had more time, I...

Sample Entry: Astronomy is the scientific study of stars, planets, comets, galaxies, and other phenomena that occur outside Earth's atmosphere (e.g. cosmic radiation). Astronomy deals with the evolution, physics, chemical makeup, meteorology, and motion of celestial objects, and also the formation of the universe. The word Astronomy comes from the Greek words astron (meaning "star") and nomos (meaning "law"). Astronomy is one of the oldest sciences. Since the dawn of man, people always...

Cosmology -- area of science that aims at a comprehensive theory of the structure and evolution of the entire physical universe. Modern Cosmological Theories Present models of the universe hold two fundamental premises: the cosmological principle and the dominant role of gravitation. Derived by Hubble, the cosmological principle holds that if a large enough sample of galaxies is considered, the universe looks the same from all positions and in all directions in space. The second point...

Quintessence (Dark Energy) -- Quintessence or dark energy is a hypothetical form of energy postulated to exist in order to explain observations of an accelerating universe. This energy would act like a vacuum pressure, pushing things apart. Other attempts to explain these recent observations involve a non-zero cosmological constant, which has the same effect. Indeed, sometimes quintessence is said to result in a non-zero cosmological constant, and conversely a non-zero cosmological...

Accelerating universe -- In the late 1990s, observations of type I supernova produced the unexpected result that the expansion of the universe appears to be accelerating. These observations appear more firm as new data has appeared. This means that the speed with which a distant galaxy recedes from us increases over time. If this trend continues, eventually we won't be able to see any other galaxies any more. This new theory of the end of the Universe has been called the Big Rip....
