The cosmic microwave background has been a treasure trove of information about the universe, as well as a source of questions that have not yet been resolved. In this video, Don Lincoln describes two unsolved mysteries of the CMB. The first makes you ask if the solar system has a special place in the universe, and the second is a giant cold spot that could be the signature of a giant void or, much more unlikely, of colliding universes.
The cosmic microwave background is the fossil remnant of the fireball of the Big Bang. Aside from demonstrating that the Big Bang happened, it can tell us how big the universe is and how much dark matter and energy the universe contains. In this video, Fermilab’s Don Lincoln guides you through this interesting topic.
The Cosmic Microwave Background, or CMB, is the remnant of the primordial fireball of the Big Bang. In this video, Fermilab’s Don Lincoln explains how it came to be. This is the first of a three-part series, with following videos to describe what secrets the CMB has revealed and what mysteries remain to be solved.
