When we clap our hands together, the electrons in each hand repel those in the other electromagnetically, preventing our hands from moving through each other.
But what would happen if our hands contained some dark matter, which is thought to interact mainly gravitationally, but not electromagnetically? The clap would separate each hand into ordinary matter, which would stop with the collision, and dark matter, which would pass through the other hand. Fortunately for us, our bodies comprise only ordinary matter, but such events can occur on a cosmic scale when two galaxies collide.
Both dark matter and our basic matter (baryon) are matter! Why don't we gather them and start a new game for bigger truths?

The Internet Origin Story You Know Is WrongThe history of the internet is repeatedly reduced to the story of the singular ARPANET. But BBSs were just as important—if not more. If I have to read more than 20 paragraphs before understanding your thesis you're doing it wrong. So much rambling. TL,DR: Bulletin Board Systems (existing before ARPANET was ever a thing) were as much, if not more influential to the development and functionality of the public internet as we know it. This is a wrong headline. The piece is promoting a book about the origins of social media, so it's strange to conflate that with Arpanet & the creation of the Internet, when it's seemingly about a different thing built on top of it called the Web.I hope Wired knows the difference
