Header Card Description: Joskus atomiydin hajoaa toiseksi ytimeksi. Silloin puhutaan radioaktiivisesta hajoamisesta, joka on heikon vuorovaikutuksen ansiota. Heikko vuorovaikutus tarvitsee massiivisia välittäjähiukkasia, jotka potkaistaan esiin tyhjästä avaruudesta virtuaalisina hiukkasina. Niin merkillistä kuin se onkin, tyhjä avaruus kihisee ja kuhisee nykyfysiikan mukaan virtuaalisia hiukkasia. Toimittajana on Sisko Loikkanen. Taustatiedot ovat Helsingin yliopiston professorin Kari Rummukaisen haastattelusta. Ohjelma on julkaistu Tiedeykkönen extra -sarjaan 12.6.2017.
