This is a 90-minute Livestream event running from 1630-1800 UTC (some local times) which honors the uniquely sophisticated devices that confirmed Einstein’s prediction of 104 years ago.


This informational and entertaining program is intended for a wide audience.

It will include the dedication of an IEEE Milestone in 3 locations: Hanford, Washington USA, Livingston, Louisiana USA, and Cascina (Pisa), Tuscany ITALY. These are the sites of the two LIGO (Laser
Interferometer Gravitational-Wave Observatories) antennas in the US, and the Virgo antenna at EGO (European Gravitational Observatory) in Italy.

You will learn about what led to the construction of these antennas, whose kilometer-scale arms can detect the tremendous gravity resultant from the merger of black holes and binary neutron stars that are up to 3 billion light-years away.

Caltech’s Rich Abbott will lead a discussion with Drs. Rainer Weiss, Kip S. Thorne, and Barry C. Barish, who jointly were awarded the 2017 Nobel Prize in Physics “for decisive contributions to the LIGO detector and the observation of gravitational waves.”

The parallel development of the European Virgo antenna will be addressed by key Virgo antenna contributors Kathy Nary Man and Jean-Yves Vinet. Current Asian developments will be described by Takaaki Kajita, principal investigator of Japan’s KAGRA antenna, who shared the 2015 Nobel Prize in Physics “for the discovery of neutrino oscillations, which shows that neutrinos have mass.”

Other contributors from the US, Italy, and France, along with government and agency dignitaries round out the program, which will conclude with the unveiling of bronze IEEE Milestone plaques at each of the 3 sites. A wealth of information is at 


Note: the registration page will include the YouTube Live and Facebook Live streaming links for this event no later than Friday, Jan. 29. You will be emailed these links at least twice, including shortly before the event starts. At the conclusion of the 90-minute event, you will see a link that you can click in order to access a live-stream from each of the three antenna locations.
