In fact, some scientists believe that, at least theoretically, it’s possible that our entire universe is a hologram.

The first inklings of this strange idea emerged in the 1970s when scientists debated the properties of a black hole and how an object’s entropy could be lost while adhering to the second law of thermodynamics. It was found, as stated by Paul Matt Sutter, an astrophysicist, in an interview with Fraser Cain that, “when it comes to black holes, the information content of a black hole is proportional not to its volume, but to its surface area.”
