Black Hole, Is Dead at 96

The New York Times / John A. Wheeler at Prince­ton Uni­ver­sity in 1967.

We all talk about black holes today. My home­work was swal­lowed up by a black hole…

One par­tic­u­lar aspect of Einstein’s the­ory got Dr. Wheeler’s atten­tion. In 1939, J. Robert Oppen­heimer, who would later be a leader in the Man­hat­tan Project, and a stu­dent, Hart­land Sny­der, sug­gested that Einstein’s equa­tions had made an apoc­a­lyp­tic pre­dic­tion. A dead star of suf­fi­cient mass could col­lapse into a heap so dense that light could not even escape from it. The star would col­lapse for­ever while space­time wrapped around it like a dark cloak. At the cen­ter, space would be infi­nitely curved and mat­ter infi­nitely dense, an appar­ent absur­dity known as a sin­gu­lar­ity. — from The New York Times

The black hole “teaches us that space can be crum­pled like a piece of paper into an infin­i­tes­i­mal dot, that time can be extin­guished like a blown-out flame, and that the laws of physics that we regard as ‘sacred,’ as immutable, are any­thing but,” he wrote in his 1999 auto­bi­og­ra­phy, “Geons, Black Holes & Quan­tum Foam: A Life in Physics.” (Its co-author is Ken­neth Ford, a for­mer stu­dent and a retired direc­tor of the Amer­i­can Insti­tute of Physics.)
