Best Place To Look For Life In The Milky Way
I would go with "globular clusters" This is a spherical group of about
a 100 million stars. One of its great features for intelligent life to have plenty of time to evolve comes from this fact. The stars these clusters contain are what our sun's age would be if we added 3 billion years. These stars were created at a time when hydrogen,helium nebular(clouds) were very dense,but these clouds had no dust to help gravity and electro-magnetizium to create fusion. They took lots of time to become stars. This is the reason these stars last so long,they have 100 of times less iron than the sun I read these stars do a lot of traveling,and this means to me they could have picked up rock planets going through space.

....or not.
http://science.nasa.gov/headlines/y2..._psrplanet.htm Most of the stars in globular clusters are even older than the 8 billion years you quoted (5 billion for the Sun, plus 3). They formed at a time when elements other than hydrogen and helium weren't very abundant in the universe, so the complex organic molecules necessary for life couldn't have formed either. (The capture a rogue planet might occasionally be possible, but the planet itself would have to have formed later for the necessary elements to be present. If that's the case, why not just look at stellar systems that were coalescing during the same era? There, planets with heavier elements would be the rule instead of the exception.)

Bill You bring in the other side of the argument. That is good,for I
like ideas (thoughts) in every direction. We agree intelligent life takes a long time to evolve. Stars that make up these clusters are longer lasting than the sun. Bert |

Ifanzian These clusters of stars are moving through space. Their gravity
would attract space dust. The planets in our solar system did not come out of the sun. Look at all the rocks,and ice that make up the Oort belt. I can't prove there are no planets in these 100 million star clusters. Like you say is true for these early stars have less iron,and other heavy elements now however being inside the Milky Way things could be different. Bert. |

LIanzian You could be closer to reality than me. We will never know for
sure. I'll only ask for one planet in that group of 100 million stars (fair?) Since I'm giving so much I want this planet to have 70% surface water,and an average temperature of 60 degrees. Rotate once in 24 hours have a moon of 2,000 miles in diameter(one fourth of the planets diameter. If you give me that Lianzian I will give you the other stars. "Please" Bert |

Bert! Look again at your post below...
"G=EMC^2 Glazier" wrote in message... ... LIanzian You could be closer to reality than me. We will never know for sure. I'll only ask for one planet in that group of 100 million stars (fair?) Since I'm giving so much I want this planet to have 70% surface water,and an average temperature of 60 degrees. Rotate once in 24 hours have a moon of 2,000 miles in diameter(one fourth of the planets diameter. If you give me that Lianzian I will give you the other stars. "Please" Bert Here you appear to list things that are essential to life... 1) planet on which to live, 2) 70% surface water, 3) average temperature of 60 degrees (F), 4) appropriate rotational period, 5) LARGE MOON !!! (?) So Bert, are we saying here that a large satellite such as Earth's Moon is essential for the evolution of intelligent life? If so, this may vastly lower the chances of finding life in other systems of the Milky Way! happy days and... starry starry nights! -- "Oh give me please the Universe keys That unlock all those mysteries!" You pay your fees, you find some keys That keeps you always groping. "Oh give me please the Happiness keys That ease the pain of biting fleas!" Today you seize you need no keys, That door is always open. Paine Ellsworth |

Hi Painius I'm going with life as we know it. (earth life) I'm
going with what I thought life is a 100 million to one shot. The earth has a big moon,and that helps stir things up. Bert |
