A group of students are carrying out an experiment in space to settle once and for all the validity of the long-held theory that sound cannot be heard in a vacuum.
The team from the Cambridge University Spaceflight (CUSF) society are launching a smartphone into orbit that will play videos of members of the public screaming in a variety of ways. As the videos are played, the team hope to find the answer to the question of whether or not anyone can hear you scream in space.
Edward Cunningham, one of the students involved with the experiment, explained the reasoning behind it.
"The whole justification behind this is that sound doesn't travel in a vacuum," he said. "And it is something we're told in school and you can actually test it in a lab.
"But we realised that no one has actually done an experiment in space before specifically to do this. And we thought it would be fun to try this out."
