A University of Sheffield team reports signs that dark matter and neutrinos may interact, offering a new way to explain a cosmic tension.
SpaceDark matter and neutrinos are linked and interact with each otherJoseph Shavit
Kuiper Belt object 2014 MU69, informally known as Ultima Thule. New simulations suggest Kuiper Belt “snowman” objects can form directly from gravitational collapse, without rare events.
