Gravitational wave detectors: the universe ripples, they listen.
These detectors (LIGO
, TAMA300, AIGO) are listening for the gravitation waves: black holes spinning and colliding, or neutron stars inspiralling to their final fates in a black hole.
Listen to the sounds that LIGO should hear when detecting neutron stars (hint: listen for the sound at the end of some of these files)
or the sounds of pulsars, black holes spinning, black holes colliding, and the sound of inspiralling black holes
Want to help detect these gravitational waves? Then join the Einsten@Home Project
; download a screen saver and your computer can use idle time to look for gravitational waves using data from a gravitational wave detector -if you find something, they will let you know
. Apparently citizen scientists and their sidekick computers have already detected 1 new pulsar
. Go team!
What does the future of gravitational wave detection look like? Hopes for the future include LISA, or 3 identical space ships/satellites, which will fly in a triangular constellation in space
. LISA should be able to hear “the emission from massive black-hole binaries that form after galactic mergers; the song of compact stellar remnants as they slowly spiral to their final fate in the black holes at the centers of galaxies; the chorus of millions of compact binaries in our own Galaxy; and possibly the faint whispers of waves generated shortly after the Big Bang
