The giant leap
As well as discussing at the technology which might take us to the stars, Berry looks at other issues as well. What is it that will motivate us to undertake such journeys and how can this motivation be maintained for the travellers? Will time dilation reduce the journey to a reasonable time or will some sort of suspended animation become necessary? At times the discussion rambles on a bit - some people might object to Berry's ideas on the future of government - but it's an entertaining read, with plenty of notes for those who want to follow up on what they have read.
