Will the universe eventually be heard?

As the Universe expands the wavelength of light from distant galaxies grows from 122 nanometers, to 900 nanometers, then 500 nanometers, etc. Does this mean that some day in the future the wavelength of that distant light will be so large that we could physically hear the distant Universe? Can the wavelength of a photon be stretched so much that it falls into the range of human hearing? Or would that require that the photon have mass?

No.

Sound waves are realy just pressure waves in the air. No air no sound. We hear things because these pressure waves cause out ear drums to vibrate and that vibrations is transfered to nerves. The nerves transfer the electro chemical data to our brains which interpret the signals as sound.

Light waves do not cause a pressure difference in air and therefore cannot be detected by our ears.

The sound of science

cdsweb.cern.ch : It sounds good!
Both the atmosphere and we ourselves are hit by hundreds of particles every second and yet nobody has ever heard a sound coming from these processes. Like cosmic rays, particles interacting inside the detectors at the LHC do not make any noise…unless you've decided to use the ‘sonification’ technique, in which case you might even hear the Higgs boson sound like music.



A group of particle physicists, composers, software developers and artists recently got involved in the ‘LHC sound’ project to make the particles at the LHC produce music. Yes…music! The ‘sonification’ technique converts data into sound. “In this way, if you implement the right software you can get really nice music out of the particle tracks”, says Lily Asquith, a member of the ATLAS collaboration and one of the initiators of the project.

CalorimeterEndcapLayers and InnerDetectorLayers are both sonifications using real 7 TeV collisions data.

October 24, 2002

With scientific instruments on NASA's Voyagers, Galileo, Cassini and more than two dozen other spacecraft, University of Iowa physicist Dr. Don Gurnett has been recording waves that course through the thin, electrically charged gas pervading the near-vacuum of outer space.

Gurnett converted the recorded plasma waves into sounds, much as a receiver turns radio waves into sound waves. "I've got a cardboard box full of cassette tapes of sounds that I've collected over nearly 40 years," he said.

Gurnett's tapes have inspired a 10-movement musical composition called "Sun Rings." The Grammy-nominated Kronos Quartet will premiere "Rings" at the University of Iowa's Hancher Auditorium in Iowa City, Iowa, on Oct. 26.

Composer Terry Riley, selected for the project by Kronos' artistic director, compiled an assortment of melody fragments and ideas from the spacecraft recordings collected near Jupiter, Venus and other planets. "It was a powerful experience to listen to this material and realize it was coming from millions of miles away," Riley said.

ScienceDaily (June 22, 2010) — Musical sounds created by longitudinal vibrations within the Sun's atmosphere, have been recorded and accurately studied for the first time by experts at the University of Sheffield, shedding light on the Sun's magnetic atmosphere.

Using state-of-the-art mathematical theory combined with satellite observations, a team of solar physicists from the University have captured the music on tape and revealed the harmonious sounds are caused by the movement of giant magnetic loops in the solar corona -- the outermost, mysterious, and least understood layer of the Sun's atmosphere. Most importantly, the team studied how this sound is decaying, giving an unprecedented insight into the physics of the solar corona.

Solar music is kinda creepy!!!!!
