This article
http://news.yahoo.com/s/nm/20070515/sc_nm/space_matter_dc
brought me to this question. How come that while universe is expanding and everything is getting away from each other, this article shows evidence of collision between galaxies ?
This would suggest that at some point those galaxies has not been moving away from each other. As far as i understand this codtrudicts some theories...

Detection on other planets has been done because of the effect they have on the sun they orbit,but if you have two planets that excert the same pull on the sun and cancelled each other out,than the detection would go unnotice,and we would miss a potential solar system

what i saw was what looked like 3 stars...(the only way to explain them) they were as high as stars and lights in the sky, so...anyway, there were 3 lights each representing the corners of a triangle. then they merged together into one point in the middle of the triangle. just as i thought..."wtf did i just see?" they did the exact same thing. i waited for it to happen again, but it didn't. what do u think it could be?(remember it looked like stars doing this) or have u had a similar sighting?

The outer galaxies are expanding at a rate close (some say more) to the speed of light.Thus the mass of these galaxies should also be close to infinty?
If you reason that the galaxies are not expanding but that only the space between the galaxies is increasing, I want to ask this question: " The space between the Earth and the Moon does not increase, nor the space between the Earth and the sun nor the space between the Sun and Alfa Centauri. So how does space carefully mannage to insert itself only in the space between galaxies?.

What if I needed to create a larger satellite to hold 10,000 people and they needed to live up there with no help from Earth and no returning to refuel and such. How would oxygen and water be possible them?

How are satellites placed into orbit? They are sent up to space, released, and they just naturally fall into place in the orbit?

If I wanted to put something into orbit around Mars, what would need to be done?
(I don't plan to, haha)

Thanks in advance!
