And he says we're on track for it to outweigh everything else on Earth.
Based on current trends, there could be more bits of digital information in use on Earth than there are atoms of matter in about 350 years — and a physicist says that digital information ought to be considered a new form of matter itself.
That means Earth is heading toward a crisis that University of Portsmouth physicist Melvin Vopson calls the "information catastrophe," according to a paper he published in the journal AIP Advances. That's because, according to his math, Vopson argues that digital information will account for half of the Earth's mass by the year 2500, making its growth impossible to sustain.
Vopson cites a theoretical framework that he calls the mass-energy-information equivalence principle, which links a number of distinct physical theories, in ZME Science's analysis. First, there's Einstein's' theory of general relativity, which links mass to energy. Then there's physicist Rolf Launder's theory that there's a fundamental energy cost tied to information processing, which Vopson combines to argue that digital bits have mass and should be considered matter alongside solids, liquids, gases, and plasmas.
"Although information manifests itself in many formats including analog information, biological DNA encoded information, and digital information, the most fundamental form is the binary digital bit because it can successfully represent or duplicate all existing forms of information," Vopson told ZME of his work.
Vopson made some exceptionally far-out claims in his ZME interview, like that the dark matter holding galaxies together could somehow be made of information. But aside from all of that, he does draw attention to an important, often-overlooked issue: the fact that ever-growing digital infrastructure could someday demand an utterly unsustainable amount of energy that the planet simply can't provide.
"Everyone should find this interesting because the projections show that we are going to produce so much digital content in the near future that the number of bits produced would equal all the atoms on Earth," Vopson told ZME.
"So the question is: Where do we store this information? How do we power this? It is a wake-up call for the big data industries, internet giants, high tech companies, energy research, and environmental research. I call this the invisible crisis, as today it is truly an invisible problem, but the projections show a different story," he added.
