This statement in the Virgo Website is false:
"First detection of gravitational waves -
On the 14th of September 2015, a gravitational wave was detected for the first ever time. "
I say this because my father was a fringe scientist obsessed with gravity waves, and invented a device nearly two decades ago which could detect gravitational waves via the ELF/ULF frequency range. Although my father has been deceased for nearly ten years, the schematics to his ULF receiver can still be found at http://elfradgroup.com/ in the Antenna & Receiver section. The website is outdated due to it being untouched since his passing, however the information is available to any and all who wish to utilize it.
Happy hunting!
