The abstracts are interesting, though the papers themselves run off into a language which is more technical than I am used to these days. Do you know if the current thought is that these are larger stars due to lack of metals? I noticed a line in the second paper about that.

Frankly I am still amazed that we can even say with certainty what we are looking at and how far back we are seeing. I never truly understood the methods for verifying that sort of data, and it seems to me that a great deal of things must be assumed. Then again, I am just an interested layman, not a physicist. I'm the guy who manipulates conceptions of physical law into believable science fiction.

On a side topic: what are yours views on the geometry of the universe? flat/hyperbolic/spherical? finite or infinite mass/energy?

If I remember correctly, my fictional universe (based on this one) is a flat, unbounded, finite expanding universe. The fact that humans view it as homogeneous and isotropic is an inconvenient side-effect of being near the center, as is the time dilation. It's part of a heterogeneous multiverse, but that's an entirely different discussion.

Are these at all related to the Nobel Prizes handed out this year? I know it had something to do with experimental evidence about the Big Bang.
