Hubble kon in 1923 aantonen dat de waargenomen 'nevels' afzonderlijke sterrenstelsels waren, waarmee bewezen werd dat het heelal veel groter was dan aanvankelijk gedacht. Een van zijn belangrijkste ontdekkingen (1929) was dat er een verband bestond tussen de roodverschuiving van verre sterrenstelsels en hun afstand tot de aarde. Hierm…
