Interesting Things with JC #1547: "John Archibald Wheeler and the Words That Shaped the Universe"

John Archibald Wheeler once said that time is what keeps everything from happening at once. He didn’t say it to sound clever. He said it because he spent his life thinking about how reality is put together, piece by piece, moment by moment.

Wheeler was born on July 9, 1911, in Jacksonville, Florida, and raised in Youngstown, Ohio. His parents were librarians. Their home was quiet, orderly, and full of books. There were no scientists in the family. He was the first to choose that path. He entered Johns Hopkins University at the age of 16 on a scholarship and earned his doctorate in physics in 1933, when he was just 21 years old.

In the 1930s, Wheeler traveled to Copenhagen to work with Niels Bohr. Together, they helped explain nuclear fission, the process by which an atomic nucleus splits and releases energy. At the time, it was theory on paper. Within a decade, it would become one of the most powerful forces ever harnessed by human beings.

In 1942, Wheeler joined the Manhattan Project. He first worked at the Metallurgical Laboratory in Chicago under Arthur Compton, then was sent to Hanford, Washington. There, massive reactors were built to produce plutonium for the atomic bomb. One of those reactors, the B Reactor, mysteriously shut down shortly after it started. The project nearly came to a halt. Wheeler identified the cause as xenon-135, a byproduct of fission that absorbed neutrons and stopped the chain reaction. His solution worked. The reactor restarted. Plutonium production continued.

While Wheeler was at Hanford, he learned that his younger brother Joe, an Army officer, had been killed in combat in the Pacific in 1944. The news reached him while he was helping build a weapon that would end the war. He rarely spoke publicly about that loss, but those close to him said it stayed with him for the rest of his life, shaping how he thought about meaning, responsibility, and the cost of knowledge.

After the war, Wheeler returned to academic life, spending most of his career at Princeton University, with a brief period at the University of North Carolina. He became one of the most influential teachers in modern physics. His first doctoral student was Richard Feynman. Others included Kip Thorne and Hugh Everett III. Wheeler didn’t just teach equations. He taught people how to ask big questions without losing discipline or precision.

In the late 1950s and 1960s, Wheeler turned his focus to general relativity, a field that had been largely set aside since Einstein. Along with Charles Misner and Kip Thorne, he helped revive it as a working science. He studied gravitational collapse, asking what happens when massive stars fall inward under their own weight.

Then came the word that changed everything.

In lectures during 1967 and 1968, Wheeler began using a simple phrase to describe an object so dense that not even light could escape it. Earlier terms like “frozen star” and “collapsar” never quite worked. Wheeler called it a black hole. The name stuck. Once it had a name, the idea spread, not just through physics journals, but into classrooms, documentaries, and everyday conversation.

Wheeler also introduced or popularized other terms that are now part of standard physics language: wormhole, quantum foam, geon. Some ideas held up. Others didn’t. Wheeler was comfortable with that. He believed progress required the willingness to be wrong on the way to something true.

Later in life, he pushed even further, asking whether reality itself depends on observation. He summed it up with a phrase that became famous: “it from bit.” The idea that physical reality may arise from information, from simple yes-or-no questions asked of the universe. He explored delayed-choice experiments, where present measurements appear to influence past behavior, not as tricks, but as serious challenges to how cause and effect are understood.

Wheeler received the National Medal of Science in 1966 and the Wolf Prize in 1981. He lived to be 96 years old and remained intellectually active almost to the end. Late in life, he described himself as a slow learner, always trying to catch up to the universe.

Every time someone says the words black hole, they are using language that didn’t exist before John Archibald Wheeler. He didn’t just study the universe. He gave us the words to talk about it.

These are interesting things, with JC.

Show Notes

This episode explores the life and legacy of physicist John Archibald Wheeler, a man whose work shaped modern physics both through theory and terminology. From his collaboration with Niels Bohr on nuclear fission to his coining of the term “black hole,” Wheeler’s story offers a rare look at how language and science intersect to frame our understanding of the universe. His philosophical speculations, such as “it from bit,” continue to influence contemporary debates on the nature of reality. This episode is ideal for lessons on physics, history of science, and the philosophy of knowledge, emphasizing how even words themselves can be tools of discovery.
