Esploratori, Pionieri, Cacciatori dello Spazio-Tempo

Una birra con Stefano Vitale

Incontri e convegni

Da cent’anni Einstein ci ha convinti che l’universo è una distesa in quattro dimensioni, curvata a causa di oggetti che spesso non possiamo vedere.

Sono più di cinquant’anni che pionieri cercano di esplorare questa distesa, cercando di captare le onde gravitazionali, increspature dello spazio tempo.

Nel 2016 i coraggiosi sono stati premiati. Un primo segnale è stato captato dagli strumenti, ed è iniziata l’astronomia gravitazionale. Non solo, quest’anno ha preso il volo il primo pezzo di un gigantesco osservatorio spaziale.

Vi racconterò di queste ricerche e di questa vita da esploratori.

Stefano Vitale è professore di Fisica all’Università di Trento. È Principal Investigator della missione LISA Pathfinder dell’Agenzia Spaziale Europea (ESA) che deve collaudare la strumentazione necessaria a realizzare l’osservatorio spaziale di onde gravitazionali che è nei piani dell’ ESA e della NASA. La missione è stata lanciata a Dicembre ed è in fase di operazioni.
