How Much Does the Internet Weigh ?
As much as a fat strawberry, apparently. It seems that a physicist named Russell Seitz wondered one day, “How much does the Internet weigh?” By which he meant the vast mass of data passing constantly through 75 to 100 million servers around the world rather than the hardware itself. You or I would probably have left it at that and gone for a pizza but Mr Seitz was made of sterner stuff as well as clearly being a man with too much time on his hands.
He knew that the Internet runs on electrons. That’s how the information is stored. And electrons are very small but they do have mass. Einstein taught us that. So he reasoned that it was possible to take all the energy (E) powering the internet and, using Einstein’s equation, (E=mc2) turn that energy into something we can weigh. And it turns out a lot of energy doesn’t weigh very much.
To store a typical email, for example, takes about 8 billion electrons. Eight billion sounds like big number, but put them on a scale, and they weigh only about “two ten thousandths of a quadrillionth of an ounce.”
So Seitz did the math, and discovered that while the Internet sucks up vast amounts of energy, something like “50,000,000 horsepower,” if you put it on a scale it does have a weight. It all totals around “two ounces.” In other words, he says, the whole internet weighs about as much as a “fat strawberry”. Others, recalculating, say it’s even lighter, more like a teeny grain of salt.
So there you have it .. I bet you feel better for knowing that .. I certainly do ..
