Relative Clocks are a representation of time dilation which is the effect of general and special relativity on the flow of time. The set of clocks show how far various spacecraft have travelled in time, relative to Earth.

Each clock in the series shows the time on Earth, as well as the time on a selected spacecraft. One hand ticks at the time on Earth, while the other hand ticks at the time on the spacecraft, revealing how time is not a fixed entity.

The work was commissioned by the UK Space Agency as part of their Human Spaceflight and Microgravity Outreach Program, and was created with Matthew Rosier.

The clocks are on display at We the Curious in Bristol, UK, until 2028.
