A new study published in Physical Review Letters might explain why the universe did not collapse immediately after the Big Bang, which is something that scientists have been striving to understand.

Pamela Fleming, Executive Vice President, The Institute for Basic Research, Florida, announces that "The recently observed 'Red Moon' establishes the lack of expansion of the universe

Scientists believe they have found a way to explain why there are not as many galaxies orbiting the Milky Way as expected.

Our universe may have emerged from a black hole in a higher-dimensional universe, propose a trio of Perimeter Institute researchers in the cover story of the latest Scientific American.

The Planck Telescope allowed physicists to draw the most detailed map of the first light emitted after the Big Bang. Some of its features do not entirely fit the standard cosmological theory, but scientists have discovered that these anomalies could be explained by how the data was processed.

Perimeter Associate Faculty member Matthew Johnson and his colleagues are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science.

Physicists Consider Implications About The Universe's First Light

The world was stunned by the recent announcement that a telescope at the South Pole had detected a cosmic fossil from the earliest moments of creation; During a live Google Hangout, 4 astrophysicists discussed the implications

Dark Energy Hidden Behind Phantom Fields

Quintessence and phantom fields, two hypotheses formulated using data from satellites, such as Planck and WMAP, are among the many theories that try to explain the nature of dark energy.

Based on observations from the South Pole Telescope, a team of international scientists has found subtle patterns in the cosmic microwave background called B-mode polarizations, according to a report in Physical Review Letters.

New Evidence Suggests Universal Collapse May Soon Be Upon Us
2013-12-12 15:09:39

Scientists have long predicted the universe could one day collapse, compressing everything contained within, much like a building that can’t contain its own weight. Sooner or later, scientists believe the universe will cause every little particle in it to become extremely heavy, causing all material to squeeze into a small, super-hot and super-heavy ball.

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.

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....

bretelles
  • In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
The word 'bretelles' comes from a French word meaning 'braces'.
