Gravitational-Wave Astronomy
Einstein predicted that gravitational waves exist. What are they, how are they produced, and what is the evidence for their existence? We looked at ways in which colliding black holes and other violent events in the universe produce gravitational waves which eventually reach the Earth.
Huge new detectors have been built on different continents to detect these signals. What they might tell us about the first moments of the universe, cosmic 'strings' and the highest energy events.
Professor John D. Barrow FRS has been a Professor of Mathematical Sciences at the University of Cambridge since 1999, carrying out research in mathematical physics, with special interest in cosmology, gravitation, particle physics and associated applied mathematics.
