What if our universe wasn’t real? – You know, though it sounds so counter-intuitive for we see it, touch it, hear, taste… but as we now know, sight – perhaps the deepest of what we consider concrete-proof- is a very narrow bandwidth of energy (nano-waves; as you well know, there are x-rays that see differently, and many other types of waves) Sound, we also hear on a narrow spectrum; there are many more sounds that we don’t hear – touch which perhaps may seem most concrete is actually entirely false, it is merely the electrical charges of atoms bouncing off one-another, interpreted by our brain (which is why someone who G0d-forbid lost an arm, can still get an itch, as the brain tells us what we are feeling, not our hand!)
