The garage in Chicago's northwest side did not look like a physics laboratory. It looked like what it was: a working-class family's utility space, filled with tools and wire and the particular organised chaos of a project in progress. The project, in the summer of 2007, was a single-engine airplane. The builder was Sabrina Gonzalez Pasterski, and she was fourteen years old. By the time she finished — having constructed the airframe, installed the engine, passed the FAA inspection, and flown the aircraft herself — she had produced a record that MIT's admissions office had never encountered: a fourteen-year-old with a home-built, certified, piloted aircraft to her name. They admitted her. She enrolled at fifteen.
Sabrina Gonzalez Pasterski was born on 18 June 1993 in Chicago, Illinois, to first-generation Cuban-American parents. She attended Chicago public schools — not private academies, not selective magnet programs, but the ordinary public schools of a large American city. Her parents were not scientists. Her father worked in construction. Her mother was a homemaker. The environment that produced Sabrina Pasterski was not one of privilege or institutional advantage. It was one of curiosity, intensity, and a complete willingness to attempt things that nobody around her had done before.
At MIT, she graduated in 2015 as valedictorian of her physics department with a perfect GPA of 5.0 — the first woman to top her department in two decades. She had completed an undergraduate career at one of the world's most demanding physics programs without a single grade lower than perfect. More importantly, she had already begun publishing research. Her papers on quantum gravity and high-energy physics were attracting attention in research communities that ordinarily do not notice undergraduate work.
She entered Harvard's PhD program in physics with a Hertz Fellowship — one of the most competitive and prestigious science fellowships in the United States. Her doctoral supervisor was Andrew Strominger, a string theorist and one of the world's leading experts on quantum gravity and black holes. Working with Strominger and Alexander Zhiboedov, she discovered the spin memory effect: a novel gravitational phenomenon — a connection between asymptotic symmetries and an effect observable in gravitational waves. The work was fundamental. In 2016, Stephen Hawking cited her research in his own papers on black holes. She received her Harvard PhD in physics in 2019.
The label "the next Einstein" is used so frequently and so carelessly in science journalism that it has lost almost all meaning. In Pasterski's case, it was attached to her not by tabloids but by the physicists closest to the frontier she was working at. Strominger himself made the comparison. The label carries its own problems — it sets an expectation that no scientist could meet, and it tends to flatten the actual content of the work into a celebrity narrative. Sabrina herself has consistently maintained a low public profile, declining most interviews, rejecting a $1.1 million consulting offer from a hedge fund that would have required her to leave physics, and continuing to publish research in the small, intense community of theoretical physicists working on the hardest problems in the discipline.
Her current work at the Perimeter Institute for Theoretical Physics in Waterloo, Canada — which she joined in 2021 as a faculty member and where she founded the Celestial Holography Initiative — concerns the attempt to encode our four-dimensional universe as a hologram: a two-dimensional conformal field theory living on the boundary of spacetime. If successful, celestial holography would provide a new mathematical framework for unifying quantum mechanics and general relativity — the central unsolved problem in physics. That she is leading a dedicated research initiative on this question, at thirty-two, with a team of collaborators working at the frontier, suggests that the label, whatever its limitations, was not entirely wrong.
Sabrina Pasterski is the daughter of a construction worker, a product of Chicago public schools, a Cuban-American who built her first airplane in a garage. She is also the physicist who Stephen Hawking cited, who rejected the hedge fund, who graduated MIT with a perfect GPA and who has spent every subsequent year at the precise edge of what human beings understand about the structure of reality. These facts belong to the same person. That is, in itself, the most extraordinary thing about her.

Celestial holography — the attempt to encode our universe as a hologram
"She turned down a million dollars to keep doing physics. The universe's structure is apparently more interesting than anyone's balance sheet."— On Pasterski's rejection of a $1.1M hedge fund offer to remain in research
The problem of unifying quantum mechanics with general relativity is the deepest open question in physics. These two theories — each extraordinarily accurate within its own domain, quantum mechanics governing the very small, general relativity governing the very large — are mathematically incompatible at the level of their foundations. Every attempt to reconcile them over the past century has either failed outright or produced mathematics so abstract that its connection to physical reality remains unclear. String theory has offered partial answers. Loop quantum gravity has offered others. The holographic principle — the idea that our three-dimensional universe might be fully encoded in a two-dimensional boundary — provides a different framework.
Celestial holography, the research program Sabrina Pasterski founded and leads at the Perimeter Institute, applies the holographic principle specifically to scattering amplitudes — the mathematical objects that describe how particles interact — mapping them onto a two-dimensional conformal field theory on the celestial sphere. If this framework succeeds, it would provide a new language for describing quantum gravity: one that might finally bridge the gap between the two most successful theories in the history of physics. The fact that the person leading this effort built her first airplane at fourteen and graduated MIT with a perfect GPA is not, in itself, a guarantee of success. Science is not won by biography. But it does suggest that the mind doing the work is exactly the kind that the problem requires: original, relentless, and constitutionally uninterested in the limits others have accepted.
