The idea is not new, but it has now gained a new layer of complexity. The possibility that we live inside a digital simulation, like pieces in a virtual reality game devised by a superior intelligence, has returned to the centre of debate, this time not in the realm of conspiratorial speculation, but by way of a scientific proposal with intriguing contours. Physicist Michael Vopson, an associate professor of Physics at the University of Portsmouth, claims to have found concrete evidence of a “source code” operating behind the scenes of the universe.
Since 2003, when philosopher Nick Bostrom of the University of Oxford suggested the hypothesis that it would be statistically more plausible for us to live in a hyper-advanced computer program than in an “original” physical reality, simulation theory has captured the imagination of researchers, thinkers and science fiction writers. Films such as The Matrix (1999) gave visual form to this existential puzzle.
However, Vopson's approach is different. Instead of looking for visual glitches in the cosmos or irregularities in the behaviour of particles, the physicist proposes a principle called the Second Law of Infodynamics. Drawing inspiration from the logic of the laws of thermodynamics, but applying it to information, Vopson maintains that the universe does not tend towards chaos, but towards an ordered compression of information.
In his reading, everything in the universe, from galaxies to DNA molecules, follows a pattern of optimisation similar to what we find in digital algorithms. The universe would thus function as a gigantic data compression system, storing, managing and reorganising information with growing efficiency.
The thesis extends to genetics as well. Vopson observes that biological systems do not show the degree of randomness expected under classical Darwinism. On the contrary, they appear to follow a logic of minimising informational entropy, behaviour typical of systems designed for digital efficiency.
“Is the machine compressing data?” he asks, almost as a provocation. For the researcher, the patterns he observes are no mere chance: they are traces of an underlying computational architecture. Traces of code.
Naturally, not everyone is convinced. Part of the scientific community remains sceptical, considering that this theory skirts the boundary between science and metaphysics, approaching a form of cybernetic theology in which an omniscient programmer replaces the traditional creator.
But regardless of the scepticism, Vopson introduces a new lens through which to observe the cosmos: that of the universe as a system that compresses, and not just expands. A compression that is not gravitational but mathematical, logical, digital – where order defeats chaos, and where perhaps, just perhaps, there is a code waiting to be deciphered.
