| Abstract 摘要 | John A. Wheeler's inventive mind covered vast areas, from nuclear physics, single-electron universe, wormholes, blackholes, quantum delayed-choice experiment, and many others. We will review the history of Wheeler's notable ideas and trace how they eventually led him from the pictures of "everything is particles" and "everything is fields" to the acceptance of the concepts of blackholes. He then proceeded to tackle the difficult question on the existence of the Universe. We will review how he combined his knowledge of blackholes and quantum mechanics to reach his new picture of the Universe as "It from Bit". |
