Are We Living in a Holographic Universe? This May Be the Greatest Revolution of the 21st Century

What if our existence is a holographic projection of another, flat version of you living on a two-dimensional "surface" at the edge of this universe? In other words, are we real, or are we quantum interactions on the edges of the universe - and is that just as real anyway?

Whether we actually live in a hologram is being hotly debated,  but it is now becoming clear that looking at phenomena through a holographic lens could be key to solving some of the most perplexing problems in physics, including the physics that reigned before the big bang,what gives particles mass, a theory of quantum gravity.   link
