Black Holes ExplainedOverviewImagine a region in space where the force of gravity is so strong that nothing—not even light—can escape.

A region so dense that an object as tiny as a walnut would have the same mass as our entire planet.First airedMay 1, 2009URL slugblack-holes-explainedGenresDocumentaireAfbeeldingenPosterAchtergrondGeen afbeeldingPictogramGeen afbeeldingBannerSeizoenenSpecials0 afleveringenSeizoen 112 afleveringenCast & crew
