Lee Smolin

• 1. The Mission From Cincinnati

  ›

  Lee Smolin was born on the 6th of June 1955 in New York City. His father Michael worked as an environmental and process engineer while his mother Pauline wrote plays. They were Jewish followers of a movement called the Fourth Way founded by George Gurdjieff. This background shaped his early worldview before he ever entered a physics classroom. He dropped out of Walnut Hills High School in Cincinnati Ohio during his teenage years. It was there that his interest in physics truly began to take root. He read Albert Einstein's reflections on two unfinished tasks from his deathbed. The first task involved making sense of quantum mechanics. The second required unifying that understanding with gravity. Smolin took these two goals as his personal mission for the rest of his life. He later admitted that neither he nor anyone else had succeeded in solving them yet.

• 2. Building Loop Quantum Gravity

  ›

  Smolin contributed significantly to loop quantum gravity through collaborative work with Ted Jacobson and Carlo Rovelli. Other key figures included Louis Crane and Abhay Ashtekar. This approach reformulated general relativity using gauge field theories. Such techniques allowed physicists to use methods from particle physics. Fields could be expressed in terms of dynamics involving loops. With Rovelli he discovered the discreteness of areas and volumes. These findings found natural expression in spin networks describing quantum geometry. Recent years have seen him focus on connecting this theory to phenomenology. He developed implications for experimental tests of spacetime symmetries. Investigations continue into how elementary particles might emerge from spacetime geometry itself.

• 3. Universes Born From Black Holes

  ›

  In 1992 Smolin published a hypothesis called cosmological natural selection. He summarized this idea in a book aimed at lay audiences titled The Life of the Cosmos. The theory suggests black holes play a role in cosmic reproduction. A collapsing black hole causes a new universe to emerge on its other side. Fundamental constant parameters like the Planck constant may differ slightly in these offspring universes. Each universe gives rise to as many new universes as it contains black holes. This provides an evolutionary advantage to universes where black holes are common. Our own universe appears fine-tuned for life because it resembles those successful predecessors. When publishing the theory in 1992 he predicted no neutron star should exceed 1.6 times the sun's mass. Later modeling raised that figure to two solar masses following more precise work by nuclear astrophysicists.

• 4. Challenging String Theory Dominance

  ›

  Smolin released his 2006 book The Trouble with Physics to critique string theory's viability. It argued science progresses fastest when communities encourage wide disagreement among professionals. Premature formation of paradigms not forced by experimental facts can slow progress. The book focused on the falsifiability of string theory due to proposals using the anthropic principle. Physicist Joseph Polchinski criticized the book in American Scientist magazine. Smolin claimed string theory suffers from serious deficiencies and holds an unhealthy near-monopoly. He called for diversity in approaches to quantum gravity research. More attention should be paid to loop quantum gravity which he helped devise. Peter Woit published a similar book titled Not Even Wrong later that same year. Both authors argued string theory was fundamentally flawed as a research program.

• 5. Time As A Fundamental Reality

  ›

  Since 2006 Smolin has collaborated with philosopher Roberto Mangabeira Unger on issues regarding time. They published a book together in 2014 called The Singular Universe and the Reality of Time. His earlier text Time Reborn appeared in April 2013 arguing physical science made time unreal. Smolin insists time is the most fundamental feature of reality instead. Space may be an illusion but time must be real according to his view. An adequate description would give a Leibnizian universe where indiscernibles are not admitted. Every difference corresponds to some other difference as the principle of sufficient reason dictates. He distances himself from mathematical platonism and rejects the idea of a timeless multiverse. All that is real exists only within moments of succession rather than outside them.

• 6. Recognition And Public Impact

  ›

  Foreign Policy magazine named Lee Smolin number 21 on its list of Top 100 Public Intellectuals in June 2008. Media outlets dubbed him one of many physicists known as the New Einstein. Newsweek listed his 2006 book The Trouble with Physics at number 17 among Books for our Time. In 2007 he received the Majorana Prize from the Electronic Journal of Theoretical Physics. The American Association of Physics Teachers awarded him the Klopsteg Memorial Award in 2009. This honor recognized extraordinary accomplishments in communicating physics excitement to the general public. He became a fellow of both the Royal Society of Canada and the American Physical Society. In 2014 he won the Buchalter Cosmology Prize for work published with Marina Cortês. His research interests span cosmology elementary particle theory and theoretical biology alongside quantum gravity.
