Heritage High School will host a presentation Thursday on gravitational wave research in Washington’s Laser Interferometer Gravitational-Wave Observatory site.
The talk will be at 6:30 p.m. in the auditorium at Heritage High, 7825 N.E. 130th Ave. Use the south parking lot and enter through the southeast corner of the building. The presentation is free and open to the public.
The program — “From Einstein’s General Relativity to a New Frontier in Astronomy” — will focus on the discovery in 2015 of gravitational waves. It will be led by Amber Henry, outreach coordinator at the LIGO facility in Hanford, near Richland.
The other site is in Livingston, La.
On Sept. 14, 2015, an international team of astrophysicists used the $1.1 billion set of twin instruments to detect a gravitational wave generated by the collision of two black holes 1.3 billion light-years from Earth.
It came almost 100 years after Albert Einstein predicted them as part of his theory of general relativity in 1916.
