Gliese 581 g - Wikipedia, the free encyclopedia
Gliese 581 g ( / ˈ ɡ l iː z ə / ), also Gl 581 g or GJ 581 g and unofficially Zarmina's World , is an unconfirmed extrasolar planet of the red dwarf star Gliese 581 , 20.5 light-years from Earth in the constellation of Libra . [ 3 ] It is the sixth planet discovered in the Gliese 581 planetary system and the fourth in order of increasing distance from the star. The discovery was announced by the Lick-Carnegie Exoplanet Survey in late September 2010, after a decade of observation. However, the ESO/ HARPS survey team claims that the planet does not exist.

Galaxy filament - Wikipedia, the free encyclopedia
In physical cosmology , galaxy filaments , also called supercluster complexes or great walls , are, so far, the largest known cosmic structures in the universe . They are massive, thread-like structures with a typical length of 50 to 80 megaparsecs h -1 that form the boundaries between large voids in the universe. [ 1 ] Filaments consist of gravitationally bound galaxies ; parts where a large number of galaxies are very close to each other are called superclusters . Discoveries of structures larger than superclusters started in the 1980s. In 1987 astronomer R.
String theory - Wikipedia, the free encyclopedia
String theory is an active research framework in particle physics that attempts to reconcile quantum mechanics and general relativity . It is a contender for a theory of everything (TOE), a self-contained mathematical model that describes all fundamental forces and forms of matter . String theory posits that the electrons and quarks within an atom are not 0-dimensional objects, but rather 1-dimensional oscillating lines ("strings"). The earliest string model, the bosonic string , incorporated only bosons , although this view developed to the superstring theory , which posits that a connection (a " supersymmetry ") exists between bosons and fermions .
Estimated distribution of dark matter and dark energy in the universe, today (top) and when the CMB was released (bottom). In astronomy and cosmology , dark matter is a currently unknown type of matter hypothesized to account for a large part of the total mass in the universe. Dark matter neither emits nor absorbs light or other electromagnetic radiation , and so cannot be directly seen with telescopes. [ 1 ] Dark matter is estimated to constitute 83% of the matter in the universe and 23% of the mass-energy. [ 2 ] Dark matter came to the attention of astrophysicists due to discrepancies between the mass of large astronomical objects determined from their gravitational effects, and mass calculated from the "luminous matter" they contain; such as stars, gas and dust.

The Solstice on December 21, 2012 ~ precisely at 11:11 AM Universal Time ~ marks the completion of the 5,125 year Great Cycle of the Ancient Maya Long Count Calendar. Rather than being a linear end-point, this cycle that is closing is naturally followed by the start of a new cycle. What this new cycle has in store for humanity is a mystery that has yet to unfold... 2012 is also considered the completion of the 26,000 year Precession of the Equinoxes cycle, and some say it also signifies the end of a 104,000 year cycle. The recent "2012" movie serves to alert a targeted 140 million people, in case they too haven't already heard the news. Unfortunately, however, the movie does a dis-service because it distorts the message of this ancient prophecy by associating it with fear and destruction, as depicted by the movie's global disaster scenario, rather than the themes of transformation and renewal the prophecy is actually based in.

How Does Life Work? Ants: Monarchs of Symbiosis
Ants are the dominant macro-animal on Earth. There are over 12,400 species we know. Ants are almost everywhere, and wherever they are, whatever their species, they live in an astonishing array of symbiotic associations. These relationships range from gut symbioses with bacteria, to herding aphids, farming fungus, to welcoming butterfly larvae into their nests and feeding them, to planting seeds for many kinds of plants. Some ant/caterpillar behavioral symbioses are elaborate: the ants herd the caterpillars, lead them to feeding areas (pastures) and bring them inside the nest (barn) for the night.
