Sabrina Pasterski: The Physicist Who Built Her Own Wings
At twelve she started assembling an aeroplane from a kit. Two years later the Zenith CH 601 XL was finished — with modifications substantial enough to require airworthiness certification — and Sabrina Pasterski flew it, with a certified instructor beside her, shortly before the National Transportation Safety Board grounded every aircraft of that model after a run of accidents. It is a useful introduction to her, because everything since has followed the same pattern: build the thing yourself, then find out whether it flies.
The Plane She Built
Pasterski was born on 3 June 1993 in Chicago, of Polish and Cuban descent. Her parents, Mark Pasterski and Maria Gonzalez, are both lawyers — which makes the aviation obsession entirely her own, though her father is also a pilot and arranged flying lessons for her in Canada. Her grandfather gave her a Cessna 150 for a birthday.
She graduated from the Illinois Mathematics and Science Academy in 2010, having been a semifinalist for the International Physics Olympiad and having completed an internship at Blue Origin while still in high school.
MIT in Three Years
MIT initially waitlisted her. Then the aerospace engineering department noticed the aeroplane, and she was admitted on the strength of it — an admissions decision that reads, in hindsight, as one of the more obviously correct ones in the institute's history.
She switched to physics. The undergraduate record is close to comic in its density: the first freshman ever named to NASA's January Operational Internship; the inaugural recipient of MIT's Freshman Entrepreneurship Award; an internship at NASA's Kennedy Space Center in 2011; research with the Compact Muon Solenoid experiment at CERN, work recognised in 2013 by the European Physical Society's High Energy and Particle Physics Prize awarded to the MIT-CMS group. She finished her bachelor's degree in physics in three years, with a 5.0 grade point average, as the first woman in decades to graduate at the top of MIT's physics class, and won the Joel Matthew Orloff scholarship award.
Twenty questions, eight minutes on the clock, and a percentile measured against everyone who has taken it. No sign-up.
Take the IQ test →Harvard, Strominger, and the Memory of Spacetime
She went to Harvard for her PhD on a Hertz Fellowship, working under Andrew Strominger, and turned to the deepest problem in physics: reconciling general relativity with quantum mechanics.
Her graduate work with Strominger and Alexander Zhiboedov produced a genuinely new result: the identification of a previously unknown gravitational memory effect, connecting symmetries of spacetime to a spin memory effect detectable in gravitational waves. "Memory" here is not metaphorical. When a gravitational wave passes through a region, it leaves a permanent trace — detectors are displaced and stay displaced, the universe having been quietly and irreversibly rearranged. Pasterski's contribution was to show that a further, subtler class of such traces exists and is tied to the symmetry structure of spacetime at infinity. It is a rare thing for a graduate student to add a new entry to the catalogue of physical effects.
Celestial Holography
From 2019 to 2022 she was a postdoctoral fellow at Princeton, where she began building out celestial holography — an approach that recasts scattering processes in four-dimensional spacetime as a conformal field theory living on a two-dimensional sphere at infinity, a hypothetical holography of the universe. Her publications between 2016 and 2021 map the territory: celestial amplitudes, conformal symmetry, asymptotic symmetries and soft theorems.
In 2021 she joined the Perimeter Institute for Theoretical Physics as founder and principal investigator of its Celestial Holography Initiative. Founding a research program in one's twenties, with an institute's backing, is the concrete measure of how seriously her field takes her — considerably more meaningful than any magazine list.
The Einstein Problem
Which brings us to the magazine lists. Scientific American profiled her as "A Teenage Pilot and Aspiring Physicist." Forbes named her to its 30 Under 30 in Science in 2015 and made her a 30 Under 30 All Star in 2017. And Ozy.com ran the headline that has followed her ever since: "This Millennial Might Be The New Einstein."
That framing is promotional rather than the verdict of any academic consensus, and it has been a mixed inheritance. Coverage of this kind converts a working theoretical physicist into a personality, invites the scepticism that always attaches to hype, and sets a bar — Einstein's — that no living scientist meets. Her actual contributions sit, as most serious contributions do, inside a specialised community that reads the papers.
Why Sabrina Is Called a Genius
The word attached to Pasterski early and for a mixture of reasons, only some of them about her mind. The aeroplane is the origin of the legend, and it is worth being precise about what it demonstrates: extraordinary persistence, mechanical competence and self-direction in a twelve-year-old — a kit built over two years, modified enough to need certification, and then actually flown. That is not intellectual genius. It is character, plus an unusual refusal to accept that a child cannot do an adult's project.
The intellectual case is separate and stands on its own. Graduating top of MIT's physics class in three years with a perfect average is a hard, comparative measure against the strongest cohort in the world. The gravitational memory result with Strominger and Zhiboedov is an original discovery in a field where original discoveries are scarce. And celestial holography — the attempt to make quantum gravity tractable by relocating it to a boundary sphere — is exactly the kind of structural reimagining that the word genius is meant for, requiring one to see a known problem in a coordinate system nobody had thought to use.
The counter-case must be stated plainly, because the hype invites it. No physicist of standing is on record calling her the new Einstein; that came from Ozy.com and was echoed by outlets looking for a story. Her major result was produced jointly with her doctoral advisor and a senior collaborator. Celestial holography is a promising research direction, not a confirmed description of nature, and it may not survive. She holds no Nobel, no Breakthrough Prize, no Fields-tier honour; her awards are a European Physical Society group prize, a graduate fellowship, and two Forbes lists. She is, at this stage, an unusually accomplished young theoretical physicist running her own program — which is a substantial thing to be, and considerably smaller than the headlines.
Legacy
The story is unfinished, which is the point. Pasterski is in her early thirties, leading a research initiative at one of the world's serious theoretical physics institutes, working on the problem — the marriage of gravity and quantum mechanics — that has defeated everyone who has attempted it for a century. If celestial holography turns out to describe the world, the case for her will be settled on the physics. If it does not, she will still have the aeroplane, the memory effect, and a record of doing difficult things ahead of schedule.
