Ajan ja avaruuden rajalla

Vielä 1960-luvulla mustat aukot olivat kammottuja kummajaisia, nyt niitä näyttää olevan ympäri avaruutta. Mustat aukot selittävät monia maailmankaikkeuden ilmiöitä, mutta niiden itsensä selittämisessä on yhä haasteita. Mustasta aukosta ei pääse valokaan karkuun ja sen rajalla aika näyttää pysähtyvän. Kaikki mustaan aukkoon putoava katoaa lopullisesti maailmankaikkeudesta - paitsi jos Stephen Hawkingin teoriaan on uskominen: mustat aukotkin säteilevät. Mustiin aukkoihin on tarjolla vain menolippuja
