Around 1927 Edwin Hubble discovered something incredible. Galaxies hundreds and thousands of light-years away were slightly redder than expected. This might seem unremarkable but light arriving from those distant galaxies should have been a very particular colour. The fact they looked redder than this implied something was happening to the light as it reached the Earth.
