extended reality 

Extended reality or XR, is a term that brings together all technologies like Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR) and all the other immersive technologies that are yet to come.

Those immersive technologies allow users to explore other realities in a whole new world using VR, augmenting their world using AR or transforming their world into a new one using MR.

Extended Reality is blurring the lines between the digital and the physical world.

Theory of Extended Reality

A broader version of the Extended Causality Hypothesis, proposing that the reality we experience (3D space, linear time, material objects, causal order) is not the whole of reality but a subset—a projection or interface of an extended reality that includes dimensions, domains, and phenomena we cannot directly access. This theory draws on analogies with virtual reality: what we experience as "reality" might be like the interface of a vast simulation, hiding the underlying code while presenting a usable surface. Extended reality would include the hidden dimensions, the higher-dimensional spaces, the domains beyond spacetime, the levels of organization we can't perceive. It would include phenomena we currently call paranormal, spiritual, or impossible—not because they don't exist, but because they exist in aspects of reality we haven't learned to access. The theory provides a framework for integrating scientific, spiritual, and anomalous experiences into a coherent understanding: all are real, but at different levels of extended reality.

*Example: "Near-death experiences, UFO sightings, mystical visions—the Theory of Extended Reality suggests these aren't hallucinations or lies. They're genuine experiences of aspects of reality we normally can't access, like a 2D being glimpsing the third dimension. The reality is extended; our perception is limited."*
