5 Things That May Surprise You About The Internet
The internet has transformed nearly every aspect of modern life, from communication to commerce, entertainment, and education. While we interact with it daily, many surprising facts about the internet remain unknown to most people. From its origins to its hidden depths, here are five things about the internet that might astonish you.
1. The Internet Is Older Than You Think
Many people associate the internet with the rise of personal computers in the 1990s, but its origins go back much further. The internet's roots lie in the 1960s during the Cold War, when the U.S. Department of Defense funded a project called ARPANET (Advanced Research Projects Agency Network).
ARPANET was designed as a decentralized communication system to ensure that information could still flow even if part of the network was destroyed during an attack. The first message sent over ARPANET was in 1969 between two computers located at UCLA and Stanford.
The term "internet" itself didn’t emerge until the 1980s, and the first website wasn’t created until 1991. So, while the World Wide Web is relatively new, the internet's infrastructure has been evolving for decades.
2. Most of the Internet Is Invisible
When you think of the internet, you probably picture websites, social media platforms, and search engines. However, this visible part of the internet, known as the surface web, makes up only a small fraction of the total internet.
The vast majority lies beneath the surface in the deep web and the dark web:
- Deep Web: This includes all online content not indexed by search engines, such as private databases, academic journals, and password-protected websites. It’s perfectly legal and accounts for around 90% of the internet.
- Dark Web: A small portion of the deep web, the dark web is only accessible with special software like Tor. While it’s often associated with illegal activities, the dark web also hosts forums and platforms for privacy-conscious users, journalists, and activists.
The existence of these layers highlights the immense scale of the internet, much of which remains unseen by the average user.
3. The Internet Weighs About as Much as a Strawberry
One of the quirkiest facts about the internet is its estimated weight—or lack thereof. Although the internet seems intangible, the data stored and transmitted within it has physical weight, albeit on an atomic level.
Physicist Dr. John D. Kubiatowicz calculated that the electrons required to power and transmit internet data add an extra weight to devices storing it. When aggregated, the internet's total weight is roughly equivalent to that of a medium-sized strawberry.
While the idea of weighing the internet is more theoretical than practical, it’s a fascinating concept that underscores the physical nature of the seemingly digital realm.
4. There’s an Internet in Space
The internet isn’t limited to Earth—it extends into space! NASA and other space agencies have developed an Interplanetary Internet to facilitate data transmission between spacecraft, satellites, and ground stations.
This network uses a protocol called Delay/Disruption-Tolerant Networking (DTN) to handle the long communication delays and potential interruptions caused by vast distances in space. The interplanetary internet has been used on missions like the Mars rovers, allowing scientists to receive data and send commands despite the millions of miles between Earth and Mars.
As humanity continues to explore space, the interplanetary internet could play a crucial role in enabling communication for future colonies on the Moon, Mars, and beyond.
5. The Internet Has a Carbon Footprint
While the internet seems intangible, its infrastructure has a significant environmental impact. Every website visit, email sent, and video streamed relies on data centers, servers, and networks that consume vast amounts of energy.
Here are some surprising facts about the internet’s carbon footprint:
- Streaming videos accounts for the largest share of internet traffic, with platforms like YouTube and Netflix contributing significantly to global data consumption.
- Data centers, which store and process internet data, use enormous amounts of electricity to power servers and maintain cooling systems. Some of the world’s largest data centers consume as much energy as small cities.
- In total, the internet is responsible for approximately 3.7% of global greenhouse gas emissions, comparable to the aviation industry.
Efforts are underway to make the internet greener. Tech companies are investing in renewable energy sources and improving energy efficiency in data centers. However, reducing individual internet use, such as lowering video streaming quality or limiting unnecessary downloads, can also help mitigate its environmental impact.
The internet is a marvel of modern technology, but it’s much more complex and surprising than most people realize. From its Cold War origins to its interplanetary applications, the internet has come a long way in a relatively short time.
As we continue to rely on this global network for countless aspects of our lives, understanding its hidden depths, physical weight, and environmental impact can help us use it more responsibly and appreciate its role in shaping our world. Whether you’re exploring the surface web or marveling at the interplanetary internet, there’s always more to learn about this transformative invention.
