Q_1_09 — Fate of the Universe

How will the universe end? This question has moved from philosophy and eschatology into hard physics, driven by the 1998 discovery that the universe's expansion is ACCELERATING (Riess et al. 1998; Perlmutter et al. 1999

Q_1_01 — The Anthropic Principle & Fine-Tuning of the Universe

The universe appears to be astonishingly fine-tuned for the existence of complex life. Alter the cosmological constant by 1 part in 10¹²⁰, or the strong nuclear force by 0.5%, or the ratio of electromagnetic to gravitati

Q_1_20 — Fractal Cosmology: Is the Universe Self-Similar Across Scales?

The observable universe organises matter into a staggering fractal-like web of galaxy filaments, walls, voids, and clusters — structures visible at scales from 1 Mpc (galaxy groups) to 600 Mpc (the Hercules-Corona Boreal
