The Weight of the Internet Will Shock You

The net is massive. But does it person … existent mass? Big server farms and miles of fiber-optic cables do, of course, but we don’t mean the infrastructure of the internet. We mean the net itself. The information. The data. The cybernetics. And due to the fact that storing and moving worldly done cyberspace requires energy—which, per Einstein, has mass—it should, successful theory, beryllium imaginable to cipher the internet’s weight.

Way backmost successful the teen days of the web, successful 2006, a Harvard physicist named Russell Seitz made an attempt. His conclusion? If you see the wide of the vigor powering the servers, the net comes retired to astir 50 grams—or astir the value of a mates strawberries. People inactive usage Seitz’s examination to this day. We’re each wasting our lives connected thing we could swallow successful 1 bite!

But a batch has happened since 2006—Instagram, iPhones, and the AI boom, to sanction a few. (By Seitz’s logic, the net would present measurement arsenic overmuch arsenic a potato.) There’s besides the information that, astir the clip of Seitz’s calculation, Discover mag projected a antithetic method. Information connected the net is written successful bits, truthful what if you looked astatine the value of the electrons needed to encode those bits? Using each net traffic—then estimated to beryllium 40 petabytes—Discover enactment the internet’s value astatine a tiny fraction (5 millionths) of a gram. So, much similar a compression of strawberry juice. WIRED thought it was clip to analyse for ourselves.

First up: the server-energy method. “Fifty grams is conscionable wrong,” says Christopher White, president of NEC Laboratories America and a seasoned of storied probe powerhouse Bell Labs. Other scientists we spoke to agreed. Daniel Whiteson, a particle physicist astatine UC Irvine and cohost of the podcast Daniel and Kelly’s Extraordinary Universe, said it’s an overly convenient mode to get “the units you want”—like assuming the terms of a doughnut could beryllium calculated by dividing the full fig of doughnuts successful the satellite by the satellite GDP. Preposterous! That would springiness america a doughnut-per-dollar figure, sure, “but it wouldn’t beryllium correct, oregon adjacent close,” Whiteson says.

Discover magazine’s calculation besides seemed a small disconnected to us. It has much to bash with the transmission of the internet, arsenic opposed to the net itself. It besides assumes a acceptable fig of electrons needed to encode information. In reality, the fig is incredibly varied and depends connected the circumstantial chips and circuits being used.

White suggested a 3rd method. What if we unreal to enactment each the information stored connected the internet, crossed each the hundreds of millions of servers astir the world, successful conscionable 1 place? How overmuch vigor would we request to encode that data, and however overmuch would that vigor weigh? In 2018, the International Data Corporation estimated that by 2025, the internet’s datasphere would scope 175 zettabytes, oregon 1.65 x 10²⁴ bits. (1 zettabyte = 1024⁷ bytes and 1 byte = 8 bits.) White suggested multiplying those bits by a mathematical term—k_BT ln2, if you’re curious—that captures the minimum vigor needed to reset a bit. (Temperature is simply a factor, due to the fact that storing information is easier successful colder conditions. Meaning: The net is lighter successful abstraction than it is successful Tucson, Arizona.) We tin past instrumentality that number, which volition correspond energy, and telephone connected E = mc² to scope the full mass. At country temperature, the entirety of the net would measurement (1.65 x 10²⁴) x (2.9×10^–21)/c², oregon 5.32 x 10^–14 grams. That’s 53 quadrillionths of a gram.

Which … is nary fun. Even if it has astir nary carnal mass, the net inactive feels weighty, to those billions of america weighed down by it each day. White, who has antecedently attempted akin philosophical estimates, clarified that successful reality, the web is truthful intricate that it is “essentially unknowable,” but wherefore not try? In caller years, scientists person floated the thought of storing information wrong the gathering blocks of nature: DNA. So what if we were to measurement the net successful those terms? Current estimates accidental that 1 gram of DNA tin encode 215 petabytes—or 215 x 10¹⁵ bytes—of information. If the net is 175 x 1024⁷ bytes, that’s 960,947 grams’ worthy of DNA. That’s the aforesaid arsenic 10.6 American males. Or 1 3rd of a Cybertruck. Or 64,000 strawberries.
