The Greatest Cosmic Puzzle: Astronomers Find Stars That Appear Older Than The Universe
Ethan Siegel

Ethan: Could a much higher matter density in the early universe influence the early stars’ development? Could gravity change and influence this too, and/or could the expansion of space-time itself maybe influence the properties of forces and matter early on? I am sure astrophysisists have discussed these possibilities in and out already. Just wondering. Cheers!
