Professor Silk will describe the state of our knowledge of neutron stars and black holes, and how new observations of gravity waves are poised to revolutionise this field.
The scientific evidence for climate change will be examined, describing how simulations of the Earth’s weather and climate are constructed and how these can be used to make assessments of what our climate and weather might be like in the coming decades.
In this final lecture we will consider whether we can plot a more successful future than our recent history might suggest and what that implies for our economic and political institutions.
We shall investigate the implications for the future of international conflict and of national defence. If preparations for the next war have already started, can we tell who is winning?
