Watchlist | Dark(ness) Matters

Over duistere tijden, lange nachten en donkere materie

December is het ideale moment om zowel het belang van licht als duisternis onder de loep te nemen. De dagen worden steeds korter en de langste nacht is weer in aantocht. Tijdens de excursie In het duister op 1 december en in het Kenniscafé | In het licht op 15 december. Licht is namelijk van levensbelang, maar is duisternis niet minstens net zo belangrijk? We doken daarom ons archief in op zoek naar duisternis: over duistere tijden, lange nachten en donkere materie.

December is the ideal time to take a closer look at both the importance of light and darkness. The days are getting shorter and shorter and the longest night is on its way. During the excursion In het duister on 1 December and in the Kenniscafé | In het licht on December 15. Light is of vital importance, but isn't darkness at least as important? We delved into our archive in search of darkness: about dark times, long nights and dark matter.
