Universe Measured: We're 156 Billion Light-years Wide! - Space.com The universe is about 13.7 billion years old. Light reaching us from the earliest known galaxies has been travelling, therefore, for more than 13 billion years. So one might assume that the radius of the universe is 13.7 billion light-years and that the whole shebang is double that, or 27.4 billion light-years wide. But the universe has been expanding ever since the beginning of time, when theorists believe it all sprang forth from an infinitely dense point in a Big Bang. |

Using Brain-based Control For Unmanned Vehicles - SpaceDaily Left: The controller mimics the part of the human brain that controls balance and limb movement, known as the olivo-cerebellar system. Engineers at Nizhny Novgorod built the integrated circuits that serve as a model of the agile controller. McKenna explains that it represents a "weakly chaotic system" of neurons coupled in a pattern that enables the controller to emulate the function of the olivo-cerebellar system. The controller can be used to replicate not only the human body's ability to carry out complex maneuvers but also, for example, the wing control of birds and insects as they adjust their angles of flight. |

Chandra Opens New Line Of Investigation On Dark Energy - SpaceDaily Left: Better limits on the amount of dark energy, and how it varies with time, are obtained by combining Chandra X-ray results with data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP). "The new Chandra results suggest the dark energy density does not change quickly with time and may even be constant, consistent with the "cosmological constant" concept first introduced by Albert Einstein," he said. If the dark energy is unchanging, the universe is expected to continue expanding forever, and more dramatic fates for the universe would be ruled out. These include the "Big Rip," where dark energy increases until galaxies, stars, planets and, finally, even atoms are torn apart, and the "Big Crunch," where the universe eventually collapses on itself. |
