From July 24, 2014. This episode won a Silver Communicator award for 365 Days of Astronomy.

Today in Q&A I’m going to tackle (or at least try to tackle) the biggest question there is:

Are We Alone?

Well, that’s the biggest question in science that I can think of anyway. So what’s the answer? Well, the short answer is “We don’t know.” We have only one place that we know has life and we’re standing on it. Earth. We have a dataset of one point. Easy to graph, huh?

But let’s take a few minutes to think about that one point and examine it closely. It’s all we’ve got, so what else are we gonna do? We don’t have dozens of data points, but we do have this one and all the scientists in the world are studying it!
