COMALite J: According to currently en vogue theory, Earth's own Moon is a complete fluke, having been knocked from the Earth itself by a massive collision early on, leaving an enormous crater in the Earth that we now call the Pacific Ocean.
Son of Thunder: "If we infer the properties of the stars that we think are reasonable, then we find the mass of the Milky Way could be half as massive as we currently believe," added DeasonBut what if some of the stars are unreasonable?
doglover: GeneralJim: doglover: machoprogrammer: Stars in the far outer reaches of the Milky Way, between 260,000 and 490,000 light-years from the galactic center, are cruising around surprisingly slowly, researchers found. Galactic mass and star velocities are linked, so the results could have big implications.I thought the galaxy was only 100,000 light years across? How does that work?Wait, really?(´･_･`)I fear for kids today.Yeah... But, outside of the structure of the galaxy is a group of stars in a "halo," held to the Milky Way by gravity, but NOT part of the structure. Thus:[www.astrobio.net image 400x399]I was more worried that he couldn't tell radius and diameter apart.You seem to have missed that, too.
doglover: LDM90: doglover: Astronomy Reporting: Just make shiat up!There's a 100 million brazillion other planets.Faster than light travel might be possible with a dyson sphere.Dark energy is like a chinchilla in a microwave.Ever hear of physics? Chemistry? Hell, even basic microbiology is more interesting than astronomers' predictions.Astronomers may have discovered a planet that has water. If it exists, it would have a breatheable oxygen atmosphere. The astronomers speculate the planet's gravity is 1.2 times that of earth.It's also a waste of time to contimplate unless it's your job, as we can't even get a mars base going, let alone interstellar trips, until the other sciences advance.Call me when the Pluto mission finally arrives, Curiosity finds Martian life, or Europa gets a probe.
