The cosmic microwave background (CMB) 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, Fermilab’s Dr. 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.
Recent research: Scientists move a step closer to understanding the cold spot in the CMB:
