Gravity clearly carries information across the cosmos - it causes clusters of galaxies to be bound together.
What carries this information?
Einstein's theory of relativity suggests that the carrier is gravitational waves. Like light, gravitational waves can travel for infinite distances through the vacuum of space, carrying not only information but also energy from cataclysmic astronomical events such as the collision of two neutron stars, a supernova, or the in-fall of a white dwarf into a black hole.
Ed will discuss the worldwide effort to detect gravitational waves a using the LIGO, Virgo and GEO600 detectors.
This 'big science' project involves around 100 academic institutions and over 1000 scientists from around the world and employs technology that rivals the Large Hadron Collider in complexity, novelty, and the potential gains for science should these signals be detected.
Come along to SciBar on Tuesday 6th September and find out more. As always the audience will be welcome to give their own opinions and ask questions. Remember there's no such thing as a silly question at SciBar!
