Relativity is a hard notion to get my head around especially when we are talking about near-lightspeed travel.
An astronaut accepts a mission to a distant world, a trip that will take seven years, to her and the crew, but over 30 will pass on Earth.
What will it be like when she returns and tries to reconnect with the husband and family she left behind?
I am no further along to understanding the phenomena but I don't need to, to understand the human impact.
This is what I like about Sawyer's writing; he goes past the shiny, "gee-whiz" aspects and brings it to the day-to-day realities of living in a world where these advances are commonplace.
Well done.
