In this account, Katherine Freese, one of the world's leading researchers in the field, gives us an account that is both cutting-edge science as well as personal, providing us with a behind-the-scenes look at the history of the tantalizing mystery of the "missing mass" and of our attempts to find out what it is, how it interacts with "normal" matter and what it all means both to history and to the future of the Universe as well as to human life in particular.
He said this is why they concluded that there must be a denser material at depth that compensates the missing mass: very likely liquid water, which is seven percent denser than ice.
