The chapter challenges the concept of dark matter by presenting a new physics theory that aims to explain galaxy rotations without its existence. It discusses the unique perspective of a theoretical physicist suggesting a classical approach to space-time with a twist of 'wobbliness'. Furthermore, it highlights a bet between physicists and Jonathan Oppenheim, along with the concerning implications of microplastics on cardiovascular health.
Ian Sample and science correspondent Hannah Devlin discuss some of the science stories that have made headlines this week, from a new theory challenging the existence of dark matter to an alarming study about the possible impact of microplastics on our health and a glimpse of a ‘waterworld with a boiling ocean’ deep in space.
