How do we experience reality? To quote the Matrix, "If real is what you can feel, smell, taste and see, then 'real' is simply electrical signals interpreted by your brain".
Given access to or the creation of the correct technology, the brain could be stimulated in such a way as to render a reality that is indistinguishable from what we now perceive to be real.
Next question is...
Could we all be encased in some sort of simulation right now? Could the world and all that we perceive, be nothing more than illusion? Scientists in Hanover Germany think that they may have found the proof, that the simulation hypothesis may have some legs. Judging from their research, it seems that all of physical reality is holographic in nature.
For the past seven years, this German set-up has been looking for gravitational waves - ripples in space-time thrown off by super-dense astronomical objects such as neutron stars and black holes. GEO600 has not detected any gravitational waves so far, but it might inadvertently have made the most important discovery in physics for half a century.
The idea that we live in a hologram probably sounds absurd, but it is a natural extension of our best understanding of black holes, and something with a pretty firm theoretical footing. It has also been surprisingly helpful for physicists wrestling with theories of how the universe works at its most fundamental level.
