A new mathematical analysis predicts the first truly habitable exoplanet will show itself by early May 2011. Well, more or less. â€œThere is some wiggle room,â€ said Samuel Arbesman of the Harvard Institute for Quantitative Social Science, lead author of a new paper posted online and to be published in PLoS ONE October 4. His calculations predict a 50 percent probability that the first habitable exoplanet will be discovered in May 2011, a 66 percent chance by the end of 2013 and 75 percent chance by 2020. |
