Is it possible we’re living in a simulation? And could humans ever re-grow limbs? These are questions Rick Edwards explores with Richard and Judy. Rick is co-host of the BBC Radio 5 Live Breakfast Show and has a new science podcast coming soon called Eureka! This week’s Book Club author is Kristin Hannah; she joins the conversation to talk about her book The Four Winds, which follows a young woman in 1930s Texas as she has to make the life changing decision to stay or leave the farm she loves as drought hits.
