Last week I was invited on Beyond Beijing (a CRI English news magazine radio show) to discuss all things extraterrestrial.
Hosted by Chris Gelken and Xu Qinduo, Beyond Beijing is a fun hour-long international radio talk show where expert guests are invited to discuss and debate current events. Fortunately for me, Chris really enjoys space-based topics, so I've been fortunate to be invited on several shows (everything from space tourism to 2012 doomsday scaremongering), so it's always a pleasure to be invited back.
However, the most recent discussion was all about whether or not we are alone in the Universe. As you might have noticed, Stephen Hawking caused quite a stir in his Discovery Channel documentary "Into the Universe," where, in his first episode, he introduced his thoughts on alien life.
One particular subject involves making contact with a not-so-friendly alien race intent on eating/assimilating/squashing mankind. Should this aggressive species pop up near Earth (via a wormhole, naturally) and plunder our planet for all its natural resources, we'd probably wish we hadn't advertised our presence to the cosmos in the first place.
