He mentioned a new model proposed by Fathers Gabriele Gionti S.J and Matteo Galaverni, an astronomer and associate astronomer, respectively, of the Vatican Observatory, which seeks to describe, using mathematics, how gravity would have functioned in the midst of what is known as “cosmological inflation,” i.e. the rapid expansion of the universe during and after the Big Bang.
“They discovered some problems with existing ideas about gravity at the very beginning of time when the universe was very compact,” Graney said, adding that they “have worked through the problems and proposed a new alternative.”
With roots dating to 1582, the Vatican Observatory is one of the oldest active astronomical observatories in the world. Its headquarters are in Castel Gandolfo, a town just outside Rome and the location of the summer residence of the popes. The Vatican Observatory also operates the Vatican Advanced Technology Telescope, located in rural Arizona about 200 miles southeast of Phoenix.
