Het heelal is onvoorstelbaar groot, en wordt steeds groter. Sterker nog: het groeit zelfs steeds sneller. Maar hoe weten we dat eigenlijk? Honderd jaar geleden zette Edwin Hubble de astronomie op zijn kop. Hij ontdekte dat sterrenstelsels van ons af bewegen en dat het heelal dus aan het uitdijen is.
In deze aflevering neemt natuurkundige Diederik Roest (Rijksuniversiteit Groningen) ons mee het heelal in. Hij legt hij ons uit hoe Hubble tot zijn ontdekking kwam, wat het dopplereffect ermee te maken heeft, en wat dit alles zegt over de toekomst van ons heelal.
