Sound of Two Black Holes Colliding ▶ Video ↓↓
#Audiovisual of gravitational waves sent out from a pair of colliding black holes that have been measured, recorded and converted to sound waves by LIGO Lab Caltech : MIT on September 14, 2015. The audiovisual displays the merger of two black holes, each about 30 times the mass of our sun. This incredibly powerful event released 50 times more energy than all the stars in the observable universe.

#Audiovisual of CMB by ESA's Planck Mission
The audiovisual is based on a simulation of ESA's Planck Mission analysis of Cosmic Microwave Background (CMB). The simulation represents the first 760,000 years of evolution of the universe, with a peak at the year 379.000. The universe was expanding and becoming more of a "bass instrument" while the cosmic background radiation was being emitted. The expanding universe "stretches" the sound wavelengths and thereby lowers their frequencies. During that time the universe was apparently dense enough to carry sound waves similar to Earth's atmosphere today.

Sound of the Sun ☉ ▶ Video ↓↓
The Sound of the Sun is based on the recordings of the Solar and Heliospheric Observatory spacecraft (SOHO) by ESA and NASA, launched in 1995. Its astrological symbol is ☉. It represents the divine spirit (circle) surrounding the seed of potential (the black dot). :)

This series of audiovisual reflects on the aesthetics of celestial sounds and attempts to engage the viewer/listener with a unique aural and visual experience. Sound does not travel through the vacuum of space though. Sound in space exists in form of electromagnetic vibrations or complex interactions of charged electromagnetic particles from the Solar Wind, ionospheres and planetary magnetosphere. These interactions are recorded by specific instruments on board of space probes and made available in an audible format. The audiovisuals arrange these available audio data into circular shapes where the beginning and end disappear. Thus the linearity of time ceases to exist and the events are isolated into single and complete shapes. The audiovisuals are inspired and based on actual data collected by Voyager 1 and 2 spacecrafts, the Solar and Heliospheric Observatory (SOHO), the Van Allen and Cluster Probes, and Laser Interferometer Gravitational-Wave Observatory (LIGO). This long-term series consists of more than 26 visuals and 21 videos. More audiovisuals are added with time and with new interesting findings in space and beyond. All audiovisuals are made with code and each audiovisual is accompanied by a video.
David Mrugala is a German architect, designer and educator who currently lives in Seoul, Korea. David’s artistic or design work is characterized by his multidisciplinary background and ranges from urban and architectural to visual and generative narratives. Besides architecture, his work is widely known through thedotisblack, an online platform for research design that aims on the development of design knowledge through generative drawings with an emphasis on natural science studies, sound analysis and data visualization. David’s work has been widely published, including exhibitions, screenings and installations.
