“Into the void” suggests we may risk an increase in cosmic rays as our planet passes into a new area of interstellar space in about 2000 years. We entered the area we are currently in around 60,000 years ago. I suggest calculating when previous transitions occurred to see if they tally with events in Earth’s history(18 February, p 38).
