12 Jun 07 - 10:29 PM (#2075388) Subject: BS: How fast do you derive? From: Thomas the Rhymer The Milky Way is a barred spiral galaxy of a Local Group of galaxies within the Virgo Supercluster. The main disk of the Milky Way Galaxy is about 80,000 to 100,000 light-years in diameter, about 250,000 to 300,000 light-years in circumference, and outside the Galactic core, about 1,000 light-years in thickness. The galaxy is estimated to contain billion stars but this number might reach 400 billion if small-mass stars predominate. As a guide to the relative physical scale of the Milky Way, if the galaxy were reduced to 130 km (80 mi) in diameter, the solar system would be a mere 2 mm (0.08 inches) in width. If life can be found circulating 1 in 187,346 of these stars, using the estimate of 200 billion, how long would these 'other' star systems extend (in millimeters) if they were stuck end to end on a continuous line... if the Milky Way galaxy were reduced to 20 miles (32.5 km) in diameter, and we assumed (for simplicity's sake) that all the star systems were equal in size to our very own Solar system? ttr |

From: Bill D "...how long would these 'other' star systems extend (in millimeters) if they were stuck end to end on a continuous line...." You mean BEFORE someone stepped on them.... perspective is an interesting thing. Even writing out how many stars, clusters, galaxies, clusters of galaxies, super-clusters...etc...are available for life to exist doesn't help most of us to wrap our heads around the concept. These are Galaxies ...many of which are bigger than the 2-4 BILLION stars in our average Milky Way galaxy. from this page "In ground-based photographs, the patch of sky in which the galaxies reside (just one-tenth the diameter of the full Moon) is largely empty. Located in the constellation Fornax, the region is so empty that only a handful of stars within the Milky Way galaxy can be seen in the image." Yes, you may go look at the images of areas of space where there are a LOT of things to see, rather than that tiny, bare section.... |

From: Bill D oh, by the way...that big picture can be viewed MUCH larger on the main page, and you can even more detail....it can be made so big it will strain your computer, up to 112,633KB... so be careful, 'cause it's hard to even wrap your head around an IMAGE that large. |

13 Jun 07 - 10:06 PM (#2076364) Subject: RE: BS: How fast do you derive? From: Rapparee Once upon a midnight dreary, As I pondered weak and weary, O'er many a quaint and etale sort of cohomology, While inducing representations, I was led to deformations, And the ramifications of modular forms in characteristic p. So I struggled to break free. Ah, discreetly I conjectured, to myself alone I lectured, As the virile bust of Fermat wrought its ghost upon my floor, Suddenly there came an insight, that these flat group schemes were finite And I represented functors never dreamed about before. Then my soul began to soar. "Taniyama!" I then shouted, As the logic from me spouted, "It all comes down to looking at the prime l equals 3!" Modularity is the conclusion, And the Frey curve an illusion, So Fermat's equation cannot have nontrivial roots in Z! Quoth the raven, "Q.E.D". |

14 Jun 07 - 11:41 PM (#2077483) Subject: RE: BS: How fast do you derive? From: Thomas the Rhymer Would you just shut up and derive? ;^) Well... here's what I'm deriving at... after hours of lugubriating... 200 Billion (star systems in the Milky May) divided by 187,346 (we are supposing that one star system for every 187,346 star systems actually sustain life) gives us a grand total of 1,067,543.5 (One Million sixty seven thousand five hundred and forty three and a half star systems that by our *totally unsubstantiated estimate* support life in the Milky Way) If the 'solar system' is 2 millimeters wide in relation to a Milky Way that is scaled to eighty miles in diameter, then in a twenty mile wide Milky Way, our solar system would a mere half of a millimeter from end to end. 1,067,543.5 ... times one half ... equals 553,717.75 millimeters ...over 1/2 a kilometer. ...or about 1/3 of a mile. ...In a Milky Way of twenty miles in length. ttr |
