Two NASA scientists put forward a new model to explain how the cosmos is and where it might be going. They say it is necessary to take account of startling recent discoveries such as the observation that everything in the Universe is moving apart at an accelerating rate. Paul Steinhardt and Neil Turok propose that the cosmos goes through an endless cycle - of Big Bang, expansion and stagnation - driven by an as yet unexplained "dark energy". picked by AutumnLotus 11 months ago tags NASA hindu concept time cosmos universe |

Distant supernovas (bright dots), captured by NASA’s Hubble telescope, open new vistas into the expansion history of the early universe. As early as 9 billion years ago, a mysterious repulsive force known as dark energy is seen exerting its influence.Even weirder than dark matter—the invisible stuff constituting most of the mass of the universe—is dark energy, a myst... read full post picked by rambler 1 year ago 0 comments edit related share plime.com |

Once upon a time, time was different. Supernova explosions in the early universe appear to age more slowly than today's supernovae, as if time itself was running slower back then, according to a recent series of astronomical observations. This cosmic time warp is exactly what should be produced by the expansion of the universe, confirming conventional big bang theory. picked by AutumnLotus 5 months ago 0 comments edit related share science |

It's an exciting time for educators and students. Before the end of the next decade, NASA astronauts will return to the moon. This time, we're planning to stay, building outposts and paving the way for eventual journeys to Mars and beyond. Today's students will be tomorrow's explorers. How will space exploration benefit their lives in the future? That's the question this competition asks of... read full post picked by paddyjoe 2 years ago 0 comments edit related share technology |

The universe’s clock has neither a start nor finish, yet time is finite according to a New Zealand theorist. The theory, which tackles the age-old mystery of the origin of the universe, along with several other problems and paradoxes in cosmology, calls for a new take on our concept of time. picked by AutumnLotus 11 months ago 4 comments edit related share plime.com |

Scientists don't know what dark energy is, but they observe its tugging effect, which causes the expansion of the universe to accelerate. Now they have seen this mysterious force in some of the largest known features of the cosmos, called superclusters and supervoids. picked by AutumnLotus 2 months ago 0 comments edit related share science |

Earth may be trapped in an abnormal bubble of space-time that is particularly void of matter. Scientists say this condition could account for the apparent acceleration of the universe's expansion, for which dark energy currently is the leading explanation. picked by AutumnLotus 1 week ago 0 comments edit related share science |

A Spanish scientist suggests that the universe's end will come not with a bang but standstill - that time is literally running out and will, one day, stop altogether. picked by Lilo 10 months ago 1 comments edit related share plime.com |

We are all submerged in a sea of undetectable particles left over from the first few seconds of the big bang, according to the latest observations from a NASA satellite. The Wilkinson Microwave Anisotropy Probe (WMAP) has confirmed the theory that the universe is filled with a fluid of cold neutrinos that remain almost entirely aloof from ordinary matter. picked by AutumnLotus 7 months ago 0 comments edit related share science |

The popular Big Bang theory has problems explaining some of the quantum level physics. A possible fix is the idea of a Big Bounce. A prebang universe that imploded (aka a Big Crunch) which caused the Big Bang appears to solve that dilemma. picked by 2manyusernames 2 weeks ago 6 comments edit related share science |

In the next few decades NASA plans to send a man (or several) to Mars. While they're still not sure of price (from $20bn to $450bn), it will take seven months to arrive in a ship powered by "an advanced cryogenic fuel propulsion system". picked by TheStep 10 months ago 2 comments edit related share plime.com |

NASA encouraged Europe to work on the development of its own manned spaceship. In such a way Europe will be able to provide the world, and mainly the United States, an additional way of get to the international space station.

According to Professor Paul Davies "Scientists have no doubt whatever that it is possible to build a time machine to visit the future". Since the publication of Einstein’s Special Theory of Relativity in 1905, few, if any, scientists would dispute that time travel to the future is perfectly possible. picked by shredtone 2 years ago 0 comments edit related share science |

Dust littered the early universe and seeded the formation of rocky planets such as the Earth. Astronomers have found 10,000 Earth masses worth of dust surrounding Cassiopeia A, the remnants of a supernova about 11,000 light-years away from our planet. The NASA Spitzer Space Telescope observations show silicates, carbon, iron oxide, aluminum oxide and other dust-forming chemicals around the blown-o... read full post picked by AutumnLotus 10 months ago 2 comments edit related share plime.com |

Astronomers have used ESO’s Very Large Telescope to measure the distribution and motions of thousands of galaxies in the distant Universe. This opens fascinating perspectives to better understand what drives the acceleration of the cosmic expansion and sheds new light on the mysterious dark energy that is thought to permeate the Universe. picked by AutumnLotus 8 months ago 0 comments edit related share science |

Astronomers have glimpsed the largest cluster of galaxies ever seen in the distant, early universe. The discovery of this far-off group, estimated to contain as much mass as a thousand large galaxies, offers further proof of the existence of the enigmatic force called dark energy. picked by AutumnLotus 1 month ago 1 comments edit related share science |
