In this interview, Dr. Brian Greene explores core ideas in modern physics: whether time began at the Big Bang or has a hidden prehistory; string theory’s promise to unify gravity and quantum mechanics despite lacking direct proof; inflation’s repulsive gravity; and the idea of infinite multiverse copies. He also examines the quantum measurement dilemma, theoretical faster‑than‑light pathways via extra dimensions, AI’s future, and the creation of the World Science Festival. Through personal anecdotes about his musician father’s influence, Greene shows how speculative, mathematics‑driven theories propel scientific discovery and public engagement.
