Do the potential benefits from contacting alien species outweigh the risks, or has Dr Hawking been watching too much V?
He's got a point. Though I'm afraid it's a bit too late in our case, we've been sending radiowaves into the universe at an ever increasing pace. And it's not likely that we're gonna stop any time soon. It might even be "too late" already, and something has picked up the signals and is now moving towards us.
{ABE}: Like a stand up comedian once once said: "There are two possibilities when it comes to alien cultures, either they are dumber than us, in which case I don't want anything to do with them, or they're smarter than us, in which case they will kill us".
