(Newser) – Scientists now believe there could be as many habitable planets in the cosmos as there are stars, and that makes life’s existence elsewhere “inevitable” over billions of years, says one. “It is sort of like running an experiment in your refrigerator—turn it off and something will grow in there,” Alan Boss says. The universe may be full of other life, but he says it’s highly unlikely we’ll find intelligent beings existing while we do, the Telegraph reports.

“Intelligent life seems to be fleeting," he says. "In terms of the universe it only exists for a fraction of time." In coming weeks, NASA’s Kepler space telescope will set off to find other habitable planets and will probably find one within 4 years, Boss notes.
