The ‘holographic principle,’ the idea that a universe with gravity can be described by a quantum field theory in fewer dimensions, has been used for years as a mathematical tool in strange curved spaces. New results suggest that the holographic principle also holds in flat spaces. Our own universe could in fact be two dimensional and only appear three dimensional — just like a hologram.

I’ve read much of the work surrounding this for years, but in the past few years this notion of the universe as a hologram has become more and more valid with the math that supports it being testable and already offering proofs. The truth of it is yet to be tested empirically, but the mathematical proofs support the feasibility of the empirical testability at some point in the future.

As Science Daily recently reported up until now, this principle has only been studied in exotic…
