One of the most important uses for water on the moon will be sheilding. Few things can beat it for both radiation sheilding and meteroric sheilding. And thermal sheilding for that matter. Don't think of a lunar base as a big bubble on the surface. Think about a bunker underneath as much ice as possi...

The magnetic field does not protect us from cosmic rays (and certainly not UV rays or microwaves: The Core was absolutely abysmal on that point). The atmosphere does. However, the magnetic fields do, to some extent, protect the atmosphere. If the flip is gradual (even as fast as a few hours, I thin...

Actually, the sun has been hotter and colder throughout history. It is a variable star. I believe it is colder now as compared to earlier. Remember that the Earth is way out of the Sun's biosphere now. Without greenhouse effects, it would be an ice ball. They have done experiments with higher CO2 le...

OK. It worked. Not well enough. Some of the findings from the study suggest that, when extrapolated over large regions, iron fertilization could cause billions of tons of carbon to be removed from the atmosphere each year. Removal of this much atmospheric carbon dioxide could have helped cool the E...

Oh god you guys know I didn't mean sea ice but rather land ice at the poles. God you people are nitpicky and don't actually care about reasoned discussion. Only the south pole has land ice. Greenland is near the north pole and has land ice, but is not at the pole. Strangely enough, I have read that...

We would in all likelyhood never have to nuke Mecca, same way we never had to nuke Moscow. Just the threat of it would be enough to make them change their thinking. Remember, the terrorist that causes Mecca's destruction by attacking the west shames his family and clan forever. We just need to anno...

Earthquakes in yellowstone don't predict an eruption there. The magma chamber would have to grow first. However, earthquakes in yellowstone have been very good predictors of eruptions and earthquakes in the US pacific rim. The magma chamber has been growing for 600,000 years. There is recent eviden...

The author says: "Although much has been changed for rhetorical purposes, it must be regarded in its essence as fact." In the text he uses the description for his text: "Chautauqua". Perhaps I was being misleading to call it a novel. I owned it as a teenager. I won't say the name of the book becaus...

well, Death is still my destination... The Count of Montecristo? :) Science Fiction. For those who haven't read it, the quote above is a rephrasing from the end of the book of the peom at the begining of the book where the last line is "and deaths my destination". It is a scifi retelling of The Cou...

@pfrit: $200B is a quarter century of NASA's entire HSF budget, or fifty years of half of it. Think about that. BTW, the idea that we count on the problems being solved by the time to need it goes for the idea of sending robots who perform better than humans on mars as well. Robots that perform bet...
