If the gravitational wave spectrum were actually a spectrum of light, what colour would it be?
Using audiolizations of theoretically calculated gravitational waves (thanks to http://web.mit.edu/sahughes/www/sounds.html), I made an audial impression of what it may sound like in the future to listen to the cosmos, like tuning into gravitational radio.
The visualisation takes the gravitational waves and maps them onto the visual spectrum. Then using information about how our eyes perceive colour from light spectra, the colour of the spectrum is determined. This colour is then presented as a function of time, as you can see in the video.
A virtual reality version of this visualisation will be demonstrated at the upcoming IEEE Virtual Reality Mixed Reality Art (MRA2016) workshop, and will be made available for iOS and Android (including a cardboard VR version) in March. This is also related to my music visualisation in virtual reality project, please have a look!
