Q_1_07 — CMB Anomalies and the Axis of Evil

The Cosmic Microwave Background (CMB) — the afterglow of the Big Bang, emitted ~380,000 years after the universe began — is the most precisely measured radiation in the history of science. It matches the theoretical pred

Q_1_18 — Loop Quantum Gravity: Discrete Spacetime and the Planck Scale

Loop Quantum Gravity (LQG) is one of two major approaches (alongside string theory) to the quantization of general relativity — the long-sought unification of quantum mechanics and Einstein's theory of gravity. LQG's fou

Q_1_13 — Cosmic Strings and Topological Defects

Cosmic strings are one-dimensional topological defects that may have formed during symmetry-breaking phase transitions in the early universe, analogous to cracks in ice or vortex lines in superfluids. Predicted by Kibble

Q_1_12 — Conformal Cyclic Cosmology: Penrose's Vision of Eternal Recurrence

Conformal Cyclic Cosmology (CCC), proposed by Roger Penrose in 2005, envisions the universe as an infinite sequence of "aeons" — each beginning with a Big Bang-like event and ending in an infinitely expanded, cold state
