The scheme is part of efforts to develop the Pentland Firth and waters surrounding the Orkney Islands in the largest planned wave and tidal generating programme in the world.

This force propels the swimmers out of the water, where they then fall forward, generating a horizontal wave.

This means that normal matter collapses more slowly than dark matter, and that when it does so it has a tendency to oscillate, generating a sound wave.
