The darkish days of the COVID-19 pandemic helped rework Sabine Hossenfelder into an unlikely social media star. Within the course of, she has raised a number of eyebrows amongst her fellow scientists. She’s additionally made an vital discovery that simply would possibly bode properly for her future analysis.
Hossenfelder turned to YouTube “to maintain my sanity” when she was unable to go to her workplace at Germany’s Frankfurt Institute for Superior Research. Really, you would possibly say she returned. She’d began a channel in 2007 however simply hadn’t been very lively. Then got here a rebranding — Science without the gobbledygook. Right now, she has 1 million subscribers (up from 50,000) and likewise enjoys a powerful and rising contingent of Patreon supporters.
A number of occasions a month, the theoretical physicist and mathematician drops a brand new video, allotting her dry wit and pithy knowledge to a loyal fan base of nerds throughout the web.
She takes her position as a science communicator significantly, aiming her movies at an viewers in search of context. “Folks can go to my channel and get the temporary, 20-minute abstract,” Hossenfelder says. “They do not should learn a complete guide or obtain a evaluation article, which they will not perceive anyway.”
Have you ever heard the one in regards to the scientist who’s bought jokes?
Her channel stakes out the no-man’s land between gee-whiz science and the heavyweight journals. From her expertise as a contract author, Hossenfelder says she “knew full-well that there have been tales you simply cannot get by an editor, not as a result of they’re fallacious, however as a result of they haven’t any well timed hook.” She goals to fill that hole.
All of it comes packaged with a spoonful of humor to assist the science go down:
Are all of us residing in a pc simulation? “I fairly like the thought … it provides me hope that issues can be higher on the following stage,” she says.
Why does 5G expertise use excessive frequencies? “There is a purpose they have not been beforehand used for telecommunication, and it isn’t as a result of millimeter waves are additionally used as goodbyes for in-laws.”
As her YouTube channel has gained traction, Hossenfelder has been capable of rent a handful of writers, although she nonetheless writes most of her personal jokes. She’s now not on the Frankfurt Institute however has a analysis place on the Munich Middle for Mathematical Philosophy. In the meantime, her dive into social media has allowed her to largely escape the perpetual pursuit of analysis grants that she says is “at all times form of like a lottery.”
Posting movies to the web, it seems, generates a extra dependable income stream to fund her work in quantum gravity. YouTube offers some cash immediately, however Hossenfelder will get extra by means of sponsors who promote on her channel, Patreon supporters and donations. Crunching the numbers, she “realized that as long as I’d maintain producing fascinating content material, I’d have an earnings.”
She hears the critics and has frank solutions for them
Hossenfelder’s science channel has additionally grow to be a prepared platform for her considerably contrarian views on the state of physics. Amongst them is what she sees as the issue of magnificence, the pursuit of simplicity. Particularly, how her colleagues who attempt to fathom the basic underpinnings of the universe are obsessive about it.
Way back to the Renaissance, scientists have sought compact and chic descriptions of area, time and movement: a kind of scientific model of Occam’s razor — that the only rationalization tends to be the proper one. However as we search solutions in a posh universe, Hossenfelder cautions that the hunt for simplicity could possibly be a useless finish. Her 2018 guide on the subject, Misplaced in Math: How Magnificence Leads Physics Astray, served as one thing of a shot throughout the bow of recent physics.
Fellow physicists, she contends, “have give you very slim notions of magnificence, which they derived from issues that labored prior to now.”
“It is all properly and advantageous. It is price a strive,” she says. “However now they’ve gotten caught on it. For this reason you see so many concepts that fail over and over.”

In her thoughts, one such failure has been the hassle to clarify darkish matter, the so-far undetected and unexplained one thing that makes up a big share of the universe. “On the level the place we are actually, it is fairly clear that it could’t be a easy story. It is bought to be one thing extra difficult than some form of new particle,” she says.
To make sure, Hossenfelder, 47, is not the one physicist questioning aloud how far the usual mannequin of particle physics could be pushed within the service of darkish matter. She describes herself as “just about a voice within the wilderness,” however some others, comparable to astrophysicist Pavel Kroupa, have publicly expressed similar skepticism.
Patricia Rankin, who chairs the division of physics at Arizona State College, says that whereas she would not completely agree with Hossenfelder’s views on physics, “I am undoubtedly in sympathy with a number of what she says about it being vital to truly delineate what science can and may’t inform us.” She praises Hossenfelder for “[challenging] individuals’s assumptions … as a result of that is actually what science is all about.”
Stacy McGaugh, a professor of astronomy at Case Western Reserve College, met Hossenfelder at a convention a number of years in the past, the place they have been each on the roster of audio system. They found a shared view on many points, together with that the gaping gap in physics left by darkish matter is perhaps a minimum of partially stuffed by a modified idea of gravity. The 2 have since collaborated on a number of scientific papers. “She’s very frank and plainspoken and isn’t afraid to talk her thoughts. And that is nice,” McGaugh says.
That frankness has positioned her at odds with some large weapons of science, together with Don Lincoln, a physicist and researcher on the Fermi Nationwide Accelerator Laboratory (Fermilab) exterior of Chicago. In contrast to Hossenfelder, his work is targeted on the experimental facet of cutting-edge physics. Lincoln, a fixture on Fermilab’s YouTube channel, co-discovered the top quark in 1995 and was part of the team in 2012 that found the Higgs boson at Europe’s Massive Hadron Collider. He and Hossenfelder have often sparred on-line, he says.
“It isn’t like we’re mortal enemies or something like that,” he is cautious to level out. However in a current episode of Science with out the gobbledygook, Hossenfelder took experimental scientists to process for his or her pursuit of ever-larger, more-powerful and costly colliders that she believes have little prospect of creating vital new discoveries.
Lincoln, nevertheless, says there are good causes to consider that darkish matter will grow to be beforehand unseen particles and never some modified type of gravity. “Most cosmologists would say that whereas it is true that these modified movement and modified gravity theories could be made to work fairly properly on the scale of rotating galaxies, or the scale of clusters of galaxies, the place they fail is on the really cosmic scale,” he says.

Hossenfelder has additionally staked out a variety of contentious and not-so-contentious positions by means of her writings and greater than 300 YouTube movies:
Synthetic intelligence? “It will make a number of issues rather more client pleasant. And principally I feel it is a good factor.”
Local weather change? “I do not assume it is an existential risk. Not by itself, however it’s a risk multiplier.”
Hossenfelder additionally “completely believes” in extraterrestrial intelligence. “I’d say ample within the universe. However ample in our galaxy? I do not know.”
“If I had time, I’d in all probability be on TikTok”
On a parallel observe to her science channel, Hossenfelder has produced an eclectic mixture of music videos, starting from Beethoven’s Ode to Pleasure to a cover of “Galaxy Song” from the 1983 Monty Python movie The Which means of Life. She discovered most of it at YouTube College. “I’m principally considering audio mixing. I’ve a factor for quirky sound results and synths and echoes and reverb and all types of distortions,” she says.
Juggling the roles of scientist and content material creator along with her private life — she lives along with her husband and has twin daughters of their early teenagers — could be a bit overwhelming, she acknowledges. In addition to YouTube, she’s on Substack and likewise hosts a podcast. “If I had the time, I’d in all probability be on TikTok, however in the intervening time I simply cannot do it,” Hossenfelder says.
It is extra acceptable these days to be each a scientist and somebody who explains science to the general public, she says. Giants such because the late Carl Sagan — and, extra not too long ago, Neil deGrasse Tyson — have helped pave the best way. However amongst her fellow scientists, “there’s nonetheless this line of thought that Sabine will not be doing analysis anymore … that she’s now doing YouTube,” Hossenfelder says.
“Mainly I do not care. I do my factor,” she says.
McGaugh, Hossenfelder’s collaborator and co-author, expresses concern that her heavy dedication to social media would possibly inevitably crowd out her analysis. “I can see the pressures,” he admits. “However Sabine thus far has managed to do each.”
Arizona State’s Rankin says Hossenfelder’s efforts to fund her personal analysis, whereas uncommon at the moment, hark again to an period when gents scientists put up their very own cash to construct scientific devices, comparable to telescopes, and pay for scientific expeditions. “However then … it was such as you simply could not afford to do science except you have been funded by means of a federal authorities,” Rankin says.
It stays to be seen whether or not others observe Hossenfelder’s lead. Regardless, she’s persevering with to construct her model with plans so as to add quizzes to go along with the YouTube movies that she hopes will “assist with understanding the fabric.”
Final 12 months, she printed her second guide, Existential Physics: A Scientist’s Information to Life’s Greatest Questions. And she or he’s engaged on two new scientific papers.
Whereas the gender divide in physics is marginally much less stark in Germany than in America — by one estimate, a quarter of Ph.D.s in physics are girls there, whereas it is only about a fifth in the U.S. — Hossenfelder eschews the “position mannequin” label.
“I am a sarcastic, annoying, completely grumpy middle-aged girl, and nobody of their proper thoughts ought to attempt to be something like me,” she says.
