La Naturalesa de l'Univers |
L'abril de 1920, Harlow Shapley i Heber D. Curtis van debatre The Scale of the Universe a l'auditori principal de l'Smithsonian's National Museum of Natural History a Washington, DC. L'octubre de 1998, P. James E. Peebles i Michael S. Turner van debatre "The Nature of the Universe" al mateix auditori. El subtítol del debat de1998 era "Cosmology Solved?." El debat es va centrar en recents controvèrsies al voltant de les determinacions d'Omega i Lambda, la densitat de la massa de l'Univers, i la seva corresponent geometria. Interpretant recents resultats observacionals de telescopis espacials i terrestres, van començar a emergir inesperades declaracions de la única cosmologia acceptable que quedava era una significant quantitat d'"energia fosca": Lambda. La comunitat astronòmica potser va restar intrigada però escèptica. Al debat de 1998, Peebles i Turner van argumentar punts de vista oposats sobre si els recents mesuraments havien solventat la qüestió tant de temps plantejada sobre la determinació dels principals paràmetres cosmològics i la geometria a gran escala del nostre Univers.
Actes del debat: Sis documents publicats del debat de1998 van
aparèixer a l'edició
de març de 1999 de Publications of the Astronomical Society of the Pacific.
