From Hillary Shaw
Your article on radio bursts coming from space mentioned the categorisation of other possible civilisations (4 April, p 8). A Kardashev Type III civilisation is defined as one that controls the power output of a galaxy. Could a Type IV civilisation control the power output of its entire universe? What would this look like to a Karadashev Type 0 civilisation like ours? Would we recognise such a civilisation, or just perceive its actions as “the laws of physics” – or worship it?
