Part 3/7:
To fully grasp ER = EPR, one must also understand the concept of holography. Juan Maldacena, who contributed significantly to this understanding, along with Leonard Susskind, posited that black hole entropy is directly proportional to the area of the black hole’s event horizon rather than its volume. This concept suggests that all information within a black hole is encoded on its surface, raising philosophical questions about the nature of reality itself.
This idea of holography implies that maybe our entire universe operates as a holographic projection of a lower-dimensional surface. The universe we perceive could be a three-dimensional illusion, all encoded on a two-dimensional boundary, a theory that remains highly debated among physicists.
