Expert: Beware of contact with aliens

An Australian scientist who this week was given a $100 million boost to help search for extraterrestrial intelligence has warned of the dangers should aliens ever make contact with Earth.

Professor Matthew Bailes said humans must ‘think very carefully’ if aliens were ever to contact us, as anything from outer space that is intelligent enough to send a signal will most likely be smarter than us — and thus most probably more dangerous.

Earlier this week physicist Stephen Hawking teamed up with a Russian billionaire to launch a new quest to discover life on other planets.
