Our Universe as a hologram

Science was born out of our desire to explain the world around us and over the course of history we have learnt that what we perceive as physical reality based on everyday experiences may not accurately reflect the inner workings of Nature. In this lecture we will present the evolution of scientific theories describing physical reality, culminating with a discussion of the most recent ideas describing our Universe as a hologram. In this paradigm the laws of physics for the entire Universe are best formulated in terms of a theory in two spatial dimensions, analogously to how an optical hologram encodes a three dimensional image in a two dimensional surface, and this holographic theory is similar to electromagnetism and the theory describing the nuclear forces. One of the macroscopic dimensions perceived in everyday life and gravity itself both emerge from the dynamics of this two dimensional theory
