Understanding Gravitational Waves
Gravitational waves are ripples in space-time created by massive objects accelerating through space. This concept originates from Albert Einstein's general theory of relativity, highlighting how gravity bends the space around masses. When two black holes collide, for instance, the resulting vibrations in space-time generate these waves, which can be detected by sensitive instruments. The first detection of gravitational waves in 2015 marked a pivotal moment in science, occurring almost a century after Einstein's prediction.
The Technology Behind Detection
The Laser Interferometer Gravitational Observatory (LIGO) employs an advanced setup known as an interferometer to detect gravitational waves. A laser beam is split into two identical waves that travel down long arms before reflecting back to interfere at a beam splitter, allowing scientists to measure minute changes in length caused by passing gravitational waves. These length changes are incredibly small, measured at a thousand times smaller than a proton's diameter, showcasing the extreme sensitivity of LIGO's technology. Such precision is necessary to capture faint signals from cosmic events occurring billions of light-years away.
Cultural Connections in Science
Corey Gray emphasizes the significance of translating complex scientific concepts into indigenous languages, as this bridges cultural gaps and promotes inclusivity in the scientific community. His collaboration with his mother to translate LIGO’s groundbreaking findings into Blackfoot demonstrates that indigenous knowledge and language have a valuable place in explaining sophisticated scientific phenomena. The connection between indigenous perspectives and modern science is vital, as it offers insights into the universe that resonate with cultural narratives. This approach not only honors indigenous heritage but also enriches the collective understanding of science.
A pivotal week in Corey Gray's life began with a powwow in Alberta and culminated with a piece of history: The first-ever detection of gravitational waves from the collision of two neutron stars. Corey was on the graveyard shift at LIGO, the Laser Interferometer Gravitational-Wave Observatory in Hanford, Washington, when the historic signal came. This episode, Corey talks about the discovery, the "Gravitational Wave Grass Dance Special" that preceded it and how he got his Blackfoot name. (encore)
