Anonymous Coward User ID: 33154959 Croatia 06/29/2014 11:16 AM Report Abusive Post Report Copyright Violation | An international team of astronomers has discovered an exoplanet in the star Gliese 832's "habitable zone" — the just-right range of distances that could allow liquid water to exist on a world's surface. The planet, known as Gliese 832c, lies just 16 light-years from Earth. (For perspective, the Milky Way galaxy is about 100,000 light-years wide; the closest star to Earth, Proxima Centauri, is 4.2 light-years away.) Gliese 832c is a "super-Earth" at least five times as massive as our planet, and it zips around its host star every 36 days. But that host star is a red dwarf that's much dimmer and cooler than our sun, so Gliese 832c receives about as much stellar energy as Earth does, despite orbiting much closer to its parent, researchers said.

Quoting: Anonymous Coward 59752870 The richest people on this earth happen to be rotten scumbags Nobody from Earth. Ever. Reality is that even in our far future scientific imagination, we could only travel at 1/10th the speed of light. So in 1000 years or more, we might be able to travel 16 light years in 160 years. |

In 1994, a Mexican physicist, Miguel Alcubierre, theorized that faster-than-light speeds were possible in a way that did not contradict Einstein by harnessing the expansion and contraction of space itself. Under Dr. Alcubierre’s hypothesis, a ship still couldn’t exceed light speed in a local region of space. But a theoretical propulsion system he sketched out manipulated space-time by generating a so-called “warp bubble” that would expand space on one side of a spacecraft and contract it on another. Alcubierre-warp-drive-overview (1) An Alcubierre Warp Drive stretches spacetime in a wave causing the fabric of space ahead of a spacecraft to contract and the space behind it to expand. The ship can ride the wave to accelerate to high speeds and time travel. The Alcubierre drive, also known as the Alcubierre metric or Warp Drive, is a mathematical model of a spacetime exhibiting features reminiscent of the fictional "warp drive" from Star Trek, which can travel "faster than light/" “In this way, the spaceship will be pushed away from the Earth and pulled towards a distant star by space-time itself,” Dr. Alcubierre wrote. Dr. White, the NYT reports, has likened it to stepping onto a moving walkway at an airport. [link to www.dailygalaxy.com] |
