(Belfast Telegraph) A scientist responsible for finding signs of life on other planets has warned that human beings should probably think twice before making contact with aliens.
Professor Matthew Bailes is based at Swinburne University in Melbourne - and is leading Australia's efforts to find signs of extra-terrestrial life.
But he warned that making contact with aliens capable of transmitting powerful signals to Earth over tens of thousands of light years could lead humanity into disaster, because they're likely to be so much more advanced.

"The history of weak civilizations contacting more advanced civilizations is not a happy one," he said.
