We are told that even at the highest estimate of the mass of the neutrinos, we can only account for about 20 percent of the universe's "missing" mass. But, the last paragraph states that even though this does not account for all the dark matter, it is enough info to help us alter our picture of the universe. The last line here is key, telling us that if the evidence is valid, then it can be added to our current understanding of the role of elementary particles in holding the universe together.
