The latest blog from the Science Geek is about the idea that we, on Earth, are being watched – as you would animals in a zoo – watched by alien (necessarily advanced) civilisations. This is the basis of many a science fiction story. But suppose it’s true? We’d never know (unless they wanted us to) as their observational technology is beyond our reach. Not even Facebook can help you here.
There’s a lot of science in this article (and some maths), and much provocation.
