The controversial theory that everything in the universe is a hologram was launched in 1997 by Juan Maldacena, theoretical physicist, and now a professor at Princeton University.
According to the theory, gravity in the universe is caused by a series of thin vibrating strings. These strings are holograms of events that occur in a universe that is simpler.
Maldacena’s theory suggests that the universe is available in nine dimensions of space at the same time.
A Japanese research team led by Yoshifumi Hyakutake of Ibaraki University in Japan has tried to provide mathematical evidence that shows that the holographic principle could be correct. Their study was published in the journal Nature.
In simpler terms, the theory suggests that the universe in which we believe we live is actually a 3D projection of an alternative dimensional universe.
