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

Q_2_04 — Stellar Evolution: The Life Cycle of Stars

Stars are born in collapsing molecular clouds, live by nuclear fusion for millions to trillions of years, and die in ways determined almost entirely by their initial mass. Low-mass stars (< 8 M☉) shed their outer layers
