What is Dark Matter and Why Does it Matter?

Описание: In this public lecture, Fermilab physicist Dan Bauer explains what scientists know about dark matter, the mysterious, invisible stuff that accounts for most of the matter in the universe. After presenting evidence for the existence of dark matter, he describes some of the physics experiments that scientists build and operate to look for signals from dark matter particles. From going deep underground to operating equipment at temperatures close to absolute zero to operating the most powerful particle collider in the world, scientists are pushing technological boundaries in their quest to discover the building blocks of dark matter. This lecture was held at Fermilab in October 2018 as part of a worldwide series of events to celebrate Dark Matter Day.
