Frases John Archibald Wheeler

„El tiempo es lo que evita que todo suceda a la vez.“

—  John Archibald Wheeler

Wheeler citó este dicho en Complexity, Entropy, and the Physics of Information, p. 10 http://books.google.com/books?id=mdjsOeTgatsC&lpg=PP1&pg=PA10#v=onepage&q&f=false, con una nota a pie de página atribuyéndola a un "grafiti en el servicio de hombres del café The Pecan Street Cafe, en Austin, Texas". Publicaciones más tardías, como en 1995 el libro de Paul Davies, About Time (p. 236), atribuyeron a Wheeler variaciones de esta frase, aunque el dicho es en realidad mucho más antiguo. La fuente más antigua conocida es de 1922; en la novela de ciencia ficción de Ray Cummings, The Girl in the Golden Atom, http://www.gutenberg.org/ebooks/21094: " 'Time,' he said, 'is what keeps everything from happening at once.' Según Science-Fiction: The Early Years, de Everett F. Bleiler, p. 171 http://books.google.com/books?id=KEZxhkG5eikC&pg=PA171, la novela fue una composición de dos historias anteriores publicadas en 1919 y 1920. También aparece en su novela de 1929, The Man Who Mastered Time http://books.google.com/books?id=YdZEAAAAYAAJ&q=%22everything+from+happening+at+once%22#search_anchor. Aparte de la de Cummings, la aparición más temprana es de 1962, en Film Facts: Volume 5, p. 48 http://books.google.com/books?id=sr0vAQAAIAAJ&q=%22everything+from+happening+at+once%22.

„Of all obstacles to a thoroughly penetrating account of existence, none looms up more dismayingly than “time.” Explain time? Not without explaining existence. Explain existence? Not without explaining time. To uncover the deep and hidden connection between time and existence, to close on itself our quartet of questions, is a task for the future.“

„We are participators in bringing into being not only the near and here but the far away and long ago. We are in this sense, participators in bringing about something of the universe in the distant past and if we have one explanation for what's happening in the distant past why should we need more?“

Wheeler's succinct summary of Einstein's theory of general relativity, in Geons, Black Holes, and Quantum Foam (2000), p. 235. http://books.google.com/books?id=zGFkK2tTXPsC&lpg=PA1&pg=PA235

„Time is nature's way to keep everything from happening all at once.“

—  John Archibald Wheeler

Wheeler quoted this saying in Complexity, Entropy, and the Physics of Information (1990), p. 10 http://books.google.com/books?id=mdjsOeTgatsC&lpg=PP1&pg=PA10#v=onepage&q&f=false, with a footnote attributing it to "graffiti in the men's room of the Pecan Street Cafe, Austin, Texas". Later publications, such as Paul Davies' 1995 book About Time (p. 236), credited Wheeler with variations of this saying, but the quip is actually much older. The earliest known source is Ray Cummings' 1922 science fiction novel The Girl in the Golden Atom, http://www.gutenberg.org/ebooks/21094 Ch. V: " 'Time,' he said, 'is what keeps everything from happening at once.' " It also appears in his 1929 novel The Man Who Mastered Time. http://books.google.com/books?id=YdZEAAAAYAAJ&q=%22everything+from+happening+at+once%22#search_anchor The earliest known occurrence other than Cummings is from 1962 in Film Facts: Volume 5, p. 48 http://books.google.com/books?id=sr0vAQAAIAAJ&q=%22everything+from+happening+at+once%22.
