This machine found something scientists thought was impossible… If you want to talk to Mico, go to this link: bit.ly/CleoAbram-Copilot In the middle of the desert, miles from any city, are two HUGE concrete tubes. They’re part of a giant machine running the most precise experiment humans have ever built… Each tube is 4 kilometers long, and inside there’s a big metal pipe. And at the end of each pipe, scientists place some of the smoooooothest mirrors ever made.
