As an amateur science-fiction writer, I was excited to read that the difficulty in detecting dark matter may be due to it – or gravity – being an emergent phenomenon of a suite of particles (18 March, p 28). Could that mean dark chemistry? Dark life? A dark intelligence thinking: “I wonder if these gravitational anomalies are caused by a suite of ‘phantom’ particles we cannot yet detect? I wonder if there is ‘phantom’ chemistry? I wonder if…”?
Modified Newtonian dynamics would kill these great possibilities, although it does seem to be the winning theory to me. Darn.
