QR1.3.2. A Prima Facie Case

How do physicists just know that our physical world isn’t virtual? Stephen Hawking explains:

But maybe we are all linked in to a giant computer simulation that sends a signal of pain when we send a motor signal to swing an imaginary foot at an imaginary stone. Maybe we are characters in a computer game played by aliens.” in (Vacca, 2005) p131

He seems open to virtualism but the next sentence is “Joking apart…”. Virtualism is a joke among the physics elite, but over 95% of the universe is dark matter/energy they can’t explain, so where does this certainty come from? The human tradition that matter is all there is seems obvious but in logic it is just an assumption, and in science it is just a theory, as matter is less than 5% of what we know is.

The discussion of virtualism in academic circles is intellectually weak. In the 2016 Isaac Asimov Memorial Debate “Is the Universe a Simulation?“, experts attacked the naïve virtualism of a fictional movie (The Matrix) but ignored what quantum theory implies, that quantum waves create physical events on demand. Instead, they attacked a straw man, a fantasy movie with no academic credentials.

In an objective world, time doesn’t dilate, space doesn’t bend, objects don’t teleport, empty space is empty, and universes don’t pop up out of nowhere. No-one would doubt that our world was objectively real, if only it would behave so. This is the sort of circumstantial evidence that a court would accept as a basis to investigate further, but first let us consider the implications of quantum realism.
