My travels ended in the Hanle Valley in Ladakh, India. The valley floor is at an altitude of 14,000 feet. It was a fitting end, given that the observatory being established there by Indian astronomers represents the next generation of observatories: higher, colder, and so remote that telescopes in such locations will have to be robotic, capable of being completely controlled from much gentler climes. The epilogue looks back at the experiments I visited and talks about the likely ones that could be the source of the discoveries that could advance physics. The epilogue also looks ahead to experiments of the future.
