SUMMARY: According to a new simulation by a team of University of Washington astronomers, Earthlike worlds could be more common that previously believed. The team performed 44 computer simulations of planet formations near a star, and found that an Earth-sized world was created nearly every time - and a terrestrial planet was in the star's habitable zone 25% of the time. The simulations also showed that the orbits of gas giants in a system might decide how much water remains on a terrestrial planet.

:wub: So this indicates that there must be much more of a chance for aliens to exist or even hominiod like aleins. I would like to know how this new data effects E.T. percentage ratios? :wub:

Not to be a naysayer or anything - I hope they're right - but ... Simulations by their very definition are based on a set of user defined parameters. The only thing the article alludes to in relation to this is that their sims "represent the extremes of what is possible ... rather than what is typical."

So basically it seems like they set up a simulation that will tend towards this conclusion anyway.
