Where Would Earth-Like Planets Find Water?

astroengine writes "The term 'Earth-like worlds' is a vastly overused and hopelessly incorrect term that is popularly bandied about to explain some recent exoplanet discoveries. Although some of the distant small worlds being discovered by the Kepler space telescope may be of Earth-like size, orbiting their sun-like star in Earth-like orbits, calling those worlds 'Earth-like' gives the impression these alien planets are filled with liquid water. It turns out that we have only a vague idea as to where Earth got its water, and it will take a long time until we have any hint of this life-giving resource on worlds orbiting stars thousands of light-years away."

    You ain't seen nothing yet.

    I've been tracking what a lot of the writers at Minyanville have to say about various things. Mauldin especially has done very good work on what the debt is going to do to us. Compound the collapse of the Euro due to their situation, and I think we are due for a very big fall.

    Some of the other indicators are that if you look at the stock market, it's been very boom and bust since the Depression (not much data from before). It' basically goes in 17 year cycles, (Slow Growth from 1932-1949, accelerating from 1949-1966 (This 34 years was unnatural due to the recovery from the Depression and WWII and the US being the only economy not devastated by the war IMO). Then 1966-1983, flat for 17 years. 1983-2000, the debt boom compounded with the tech bubble, 17 years. Now we are in year 11 since the boom. Any ideas on when we'll be seeing better times? Not for the next 5 year by cyclical estimates. Maybe more if the effects of recent measures extends this (a reverse of the boom after the depression) compounded by the wreckage of the policies of every administration going back to Roosevelt's New Deal and Johnson's Great Society, and every kick the can down the road Congress and administration since.
