A leading U.S. astronomer says there is no hope of finding alien life in space because all other planets discovered so far are to hostile for life.
Howars Smith, a senior astrophysicist at Harvard University, says he believes humans are alone in the universe. 500 planets that shows similar "Earth" conditions are analysed and they are all hostile to life as we know it. "We have found that most other planets and solar systems are wildly different from our own," he says. "They are very hostile to life as we know it". Other planets are too different from our own and even if they did support life it would be impossible for us to contact it.
Some other scientists remain confident life will be found. But if they find it, how will they contact other civilization many light-year far away? Smith maybe have right, but maybe not. It's upon you in which story you want to believe.
