The Search for Gravity Waves (cc)

Search for Gravity Waves, The (cc)

"Highly Recommended. State Standards approved, this program discusses the scientific efforts to detect gravity waves; its content is current, accurate and scholarly. Viewers will be able to express an understanding of what gravity waves are; describe the efforts made by the scientific community to detect gravity waves; discuss Einstein's predictions and theory of general relativity; also explain why detection of gravity waves is important." - California Learning Resource Network (CLRN)
"Recommended. This program presents a clear and interesting overview of efforts to detect gravity waves, ripples through space-time caused by moving objects. Gravity waves are predicted by Einstein’s general relativity theory. The production values are excellent with particularly good simulation graphics. The film discusses in detail the plan to build the Australian International Gravitational Observatory (AIGO). In combination with other laser interferometer installations in other countries, scientists hope to finally detect the elusive gravity waves. The background and importance of this detection effort is described in easily understood terms." -EMRO Review
Just north of Perth, Australia, is a new kind of observatory, called AIGO (the Australian International Gravitational Observatory), which could revolutionize our understanding of the universe. AIGO is trying to detect gravity waves, which are ripples through space-time caused by moving objects. They were predicted by Albert Einstein in his theory of general relativity, but have never been detected. If we can detect gravity waves, astronomers will no longer be limited by how far they can see into space. They will be able to hear gravity waves generated by huge masses such as pairs of neutron stars or the formation of black holes. It may be many years before AIGO is capable of detecting gravity waves, but scientists involved believe it will be worth the wait.
