In an attempt to reconcile some of the paradoxes discovered when studying them, physicists have proposed stranger hypotheses still, with one suggesting that they imply we live in a holographic universe, where all of what we see and perceive is in fact encoded at our universe's boundary, a 3D (plus time) representation of a two-dimensional (plus time) universe. Further than that, some have suggested that it could imply that our universe is within a black hole of a larger universe.
