Astronomy and Cosmology

I was just curious if it would be possible to construct solar sails at the moons equater to increase the moons spin to near the moons escape velocity. It would make mining a lot easier. After all the moon is just one big spaceship up there relative to us. Landing at the poles would be simple and mining ores could be moved to the equater and pushed off the surface to waiting nets for transport. No problems launching bulk ores Not that we'd ever do it. I was just wondering if it was feasable.:scratch: Just aman

I read in last month discover magazine about how scientists can only explain the odd orbit of the planet neptune and pluto, is that there is a very large planet out there that distorts them. Now, for some time I have accepted this theory. But in this months, it describes a galaxy on the collapse 50 billion light years away. Now, it makes me wonder. Pluto is no where near 50 billion light years. It's not even a billion, So, if this theroy was to be true, This planet would have to be big enough to attract them. But, if we can see 50 billion light years away, and we havent found this 10th planet, it would have to be hard to fathom the size of this planet.

Hubble's law states that there is a linear relationship between distance and recessional velocity, correct? Following this line of thought, wouldn't there be very distant galaxies that are traveling faster than light? How is this not a violation of special relativity?

Should we be concentrating more on possible Middle Eastern Terrorism, or Astronomical Terrorism?
