Early Life & Education

Sabine Hossenfelder was born on September 18, 1976, in Frankfurt am Main, West Germany. Details about her parents and siblings are not publicly disclosed, as she prioritises her family’s privacy.

Of German nationality and presumed Caucasian ethnicity, her religious beliefs are not documented.

Growing up in Frankfurt, Sabine developed an early interest in mathematics and physics, inspired by the city’s academic environment.

Sabine earned a diploma in mathematics from Goethe University Frankfurt in 1997, at age 21. She continued at the same institution, completing a master’s degree in 2000 and a doctorate in theoretical physics in 2003.

Her dissertation, “Schwarze Löcher in Extra-Dimensionen: Eigenschaften und Nachweis” (Black Holes in Large Extra Dimensions), supervised by Horst Stöcker, focused on microscopic black-hole production in models with large extra dimensions.

Career

Sabine began her career with a postdoctoral role at the GSI Helmholtz Centre in Germany, followed by research fellowships at the University of Arizona, UC Santa Barbara, and the Perimeter Institute in Canada.

In 2009, she became an assistant professor at NORDITA in Stockholm, Sweden. Since 2015, she has been a research fellow at the Frankfurt Institute for Advanced Studies, leading the Analogue Systems for Gravity Duals group until 2023.

She now works at LMU Munich’s Centre for Mathematical Philosophy, researching locality and fine-tuning in quantum mechanics.

Her work focuses on quantum gravity phenomenology, particularly Lorentz invariance and experimental evidence, and she advocates for superdeterminism in quantum mechanics.

As a science communicator, Sabine started her blog, Backreaction, in 2006, which she co-runs with her husband, physicist Stefan Scherer.

Her YouTube channel, launched in 2011 and formerly called “Science without the Gobbledygook,” has over 1.7  million subscribers, offering concise explanations of physics, cosmology, and controversial topics like free will and trans issues.

She’s authored over 70 research papers and writes for Forbes, Quanta Magazine, New Scientist, and Scientific American.

Her books, Lost in Math: How Beauty Leads Physics Astray (2018) and Existential Physics: A Scientist’s Guide to Life’s Biggest Questions (2022), critique the pursuit of aesthetic theories in physics.

Personal Life

Sabine, 49, resides in Munich, Germany, with her husband, physicist Stefan Scherer, whom she married in 2006.

They have twin daughters born in December 2010. Her height is not documented, and no past relationships are public.

A Virgo, she’s known for her dry wit and no-nonsense approach, often tackling controversial topics like gender and science funding.

She enjoys engaging with her audience through her blog and YouTube, where she addresses physics and societal issues.

Net Worth

Sabine’s net worth is estimated at $1 million to $3 million.

Her income derives from YouTube ad revenue (estimated $5,000-$10,000 monthly from 1 million subscribers), book royalties (Lost in Math sold over 320,000 copies), freelance writing, speaking engagements, and physics consultations ($50 for 20 minutes).
