The hand that drops the apple from a tree is the same hand that moves celestial gears: gravity. This one of
Newton is one of the great insights that changed the way we read the universe. Then there are
more arrived. Two hundred years later, Einstein introduces a new twist. With the promotion of the
speed of light to absolute magnitude, in the theory of special relativity space and time are linked by
always. And in the theory of general relativity, gravity is transformed, it becomes the imprint left by the
matter in the “soft” geometry of spacetime. Shortly thereafter, a further surprise. The gaze of
Hubble unveils the possibility of a universe that is no longer static and unchanging, but expanding, with a beginning,
an age, a history. Meanwhile, Dirac from the solutions of an equation brings out antimatter. To be understood, however,
much remains. We know that the expansion of the universe accelerates, but not what drives it. What if our
universe was one of many bubbles in a cosmic foam? If there were other dimensions rolled up on
themselves and invisible to us? Mirabilis is a ticket to a journey to places so unfamiliar as to appear
fantastic.
