Good find.

I'm a little confused by these parts:

Stmt 1: "Dark matter - which does not emit or reflect enough light to be "seen" - is thought to make up 25% of the Universe."

Stmt 2: "This provides the first direct proof that dark matter must exist and that it must make up the majority of the matter in the Universe."

I've heard statements comparable to 2 previously.
I'm having trouble assimilating these: Is it "25%" or is it "the majority of the matter in the Universe?" Or am I missing something?
