I'm confused. From the article: "This is explained by the Hubble-Lemaître Law, the observation that more distant galaxies are moving away at a faster rate."

I'm confused. From the article: "This is explained by the Hubble-Lemaître Law, the observation that more distant galaxies are moving away at a faster rate." If we observe an accelerating universe how can be that galaxies in the past move away at a faster rate?

Because more and more negative mass fills in the space left behind by the expansion creating further expansion?

  why would negative mass fill in the space rather than just "zero mass?"

    Negative mass has greater pressure to displace vacuum in a similar way that mass does? That was my assumption. Perhaps not!
