Most people who encounter Eric Weinstein in the UFO space hear the headlines: Epstein was a science spy. New Mexico connects everything. The crash-retrieval program has no physicists. But beneath those claims – and more fundamental to understanding them – is an argument Weinstein has been building for years that has nothing to do with flying saucers and everything to do with the history of physics itself.
In his March 2026 interview with Jesse Michels, sitting across from astrophysicist Eric Davis, Weinstein laid it out more completely than he ever has before. The argument runs like this: there was once a serious, well-funded effort to understand gravity at a deep level. It involved some of the best physicists alive. Then it disappeared – and was replaced by a research program that has produced zero experimental results in over four decades. Whether or not that happened by design, the effect is the same: the physics community lost the ability to make progress on the most strategically important force in nature.
That argument stands on its own, independent of any UFO claim. And it may be the most important thing Weinstein has said.
The Golden Age That Vanished
The phrase “golden age of general relativity” is not Weinstein’s invention. It appears in the history-of-science literature to describe a period from roughly the late 1950s through the early 1970s when general relativity – Einstein’s theory of gravity – was transformed from a mathematical curiosity into a living, experimental science. Black holes went from theoretical oddities to objects people were trying to detect. Gravitational waves went from thought experiments to engineering targets. The field attracted serious talent and serious funding.
Then, as Weinstein tells it, the trail goes cold.
He first noticed the gap as a graduate student in the 1980s. At an American Physical Society meeting, he asked the APS historian what had happened to gravity research. The historian confirmed that anti-gravity and advanced gravitational research had effectively disappeared in the early 1970s but could not explain why.
“The APS historian had no answer for me as to where this disconnect came from. He said it disappeared in the ’70s but he never saw what happened.”
Davis, who was in the room, confirmed independently that he had noticed the same pattern – and that his mentor, physicist Bob Forward at Hughes Research Labs, had been one of the last people actively working on gravitational physics before the field went quiet.
The Manhattan Project for Gravity
Weinstein pointed to a 1971 Australian intelligence document – written by Harry Turner, head of Australia’s nuclear division – that lists what the Australians believed the Americans were doing with gravity. The document names six universities, the Institute for Advanced Study, and researchers including Arnowitt, Deser, Dyson, and Oppenheimer. Weinstein’s characterization:
“It sounds like the Manhattan Project for Gravity.”
He then traced two specific funding channels. Agnew Bainson and John Wheeler set up physicist Bryce DeWitt at the University of North Carolina Chapel Hill at the Institute of Field Physics. Separately, Roger Babson appeared to be connected to Lewis Witten – a gravitational physicist out of Johns Hopkins – who ended up at something called the Research Institute for Advanced Study (RIAS), housed within the Glenn L. Martin Company. RIAS had Sheldon Glashow within it. It had Rudolph Kallman. Topologist Solomon Lefschetz came out of retirement to work there.
“We’ve got Sheldon Glashow, Rudolph Kallman, Solomon Lefschetz, Deser, Arnowitt, Dyson. This begins to feel like the boys are back in town. This is physics firepower.”
And then – in the early 1970s – the entire effort appears to evaporate. Weinstein doesn’t claim to know exactly why. But he has a hypothesis about what replaced it.
String Theory as a Blocking Mechanism
In 1984, the Green-Schwarz anomaly cancellation result electrified theoretical physics. Ed Witten – son of Lewis Witten, the gravitational physicist from RIAS – directed the field toward string theory. The phrase “the only game in town” took hold. Weinstein describes what followed:
“If you said anything that isn’t string during this period right after 1984, it’s a bloodbath. Feynman is upset about it. Penrose is upset about it. Penrose basically pleads no contest and says I’m voting with my feet and going to go do cosmology in Texas.”
Weinstein’s claim is not that string theory is wrong in principle. His claim is that it has functioned as what he calls a “blocking mechanism” – an intellectually consuming pursuit that absorbs the best minds in physics and prevents them from making progress on the actual frontier.
“Quantum gravity looks like a blocking mechanism that basically binds to the receptor of a physicist’s mind and causes them not to make progress. And so we’re 42 years into an unquestionable – it feels like a mass psychosis.”
He points out that even Leonard Susskind, one of the fathers of string theory, recently said on a podcast that “we have to go back to the beginning, we have to question absolutely, we got this wrong.” But Susskind’s prescription was to go back to the foundations of string theory – not to question the string assumption itself.
“It’s an infinite regress. So one of the questions that I have is: is physics just too dangerous to do in a university setting? It seems that way to me.”
The Nuclear Precedents
Weinstein isn’t speculating in a vacuum when he suggests physics can be classified. He cited two real historical episodes.
John Aristotle Phillips was a Princeton junior who chose Freeman Dyson as his thesis advisor and proposed designing an atomic weapon using only publicly available information. Dyson agreed to tell him only whether it would work – providing no information. Phillips submitted his design. Dyson confirmed it would work. Page 20 was removed. The thesis is reportedly not available in the Princeton Library with the other junior theses.
Howard Morland was a journalist at The Progressive who reconstructed the Teller-Ulam hydrogen bomb design from declassified fragments. The government attempted prior injunction under the Atomic Energy Acts’ “restricted data” doctrine – then discovered they couldn’t stop him because every piece of information he used had already been individually declassified.
Weinstein’s point: these episodes demonstrated to the government that physics knowledge, once it exists, cannot be contained at the technology level. You have to contain it at the science level – by controlling what research gets done in the first place.
“Shortly after that we get string theory and we become kind of incapable. It’s like the glass bead game – something that amuses people at a very high level. We’re turning the best physicists into chess players because nobody ever blew something up with a rook.”

The Renaissance Technologies Question
Weinstein then raised what may be his most provocative institutional observation. He said he personally knows a great many of the world’s top theoretical physicists and sees no indication that any of them are involved in a classified physics program – with one exception.
“There’s one black hole that you go into and you don’t come out of, called Renaissance Technologies, that hires in these exact specialties. It’s got a level of profitability that doesn’t really make sense based on what I know about markets, and it’s got a secure campus. It’s right next to Brookhaven National Laboratory, and it has the resources of SUNY Stony Brook.”
Renaissance Technologies is a real firm founded by the late Jim Simons, a mathematician who built the Simons Center for Geometry and Physics at Stony Brook. David Spergel, president of the Simons Foundation, chaired NASA’s UAP independent study panel. These are documented institutional facts.
Weinstein does not claim Renaissance Technologies is a front for a classified physics program. He observes that if you wanted to find where the top physicists went – the ones who disappeared from academia and never surfaced elsewhere – you would look for exactly this kind of institutional configuration: extraordinary resources, proximity to a national laboratory, security, and a plausible cover story.
“If you wanted to figure out that the NSA existed while there was still ‘No Such Agency,’ you’d look at number theory PhDs and ask what zip codes they live in when they don’t get an academic job that’s visible. And you’d find they’re clustered around Fort Meade. Do the same thing for this.”
DESI and the Cracks in General Relativity
Weinstein connected the theoretical argument to breaking experimental news. The Dark Energy Spectroscopic Instrument (DESI) – a major observational cosmology project – has recently published results suggesting that dark energy may not be constant after all but is evolving over time.
This matters because of Lovelock’s theorem, which Weinstein walked through in the interview. In general relativity, there are only two divergence-free tensors you can construct from the geometry: the Einstein curvature tensor and the cosmological constant (lambda) times the metric. If lambda is not actually constant – if dark energy is dynamical – then one of the two pillars of Lovelock’s theorem is weakened, and general relativity itself begins to face a structural challenge.
“If you lose the constancy of dark energy, you’re starting to actually put general relativity in some peril.”
Davis, a working physicist, responded: “That’s very interesting. I hadn’t thought about that.”
This is Weinstein doing what he does best – connecting a brand-new experimental result to foundational theory in a way that working scientists in adjacent fields haven’t yet processed. It is exactly the kind of cross-domain thinking that the UFO question needs and almost never gets.
Why This Matters for UFOs – and Beyond
The connection Weinstein draws between all of these threads is elegant and, crucially, does not require believing in crash retrieval to be important.
If gravity is the next strategic force – after the strong nuclear force was weaponized in 1945 and electromagnetism was harnessed for radar, communications, and directed energy – then whoever understands gravity first gains an advantage that dwarfs anything in the current arsenal. If the golden age of gravity research was deliberately ended or redirected, that is a story about national security and the control of science, regardless of whether any UFO ever crashed.
If string theory has functioned as a blocking mechanism – whether by design or by the natural sociology of academic incentives – then 42 years of the best minds in physics have been diverted from the frontier that matters most. And if the alleged crash-retrieval program really has no theoretical physicists, then the absence Weinstein identified in the UFO story is the same absence he identified in academic physics. They are, as he put it, “two sides of the same coin.”
“Are these two sides of the same coin – that we don’t make progress beyond the standard model and general relativity, and we don’t have any physicists on the UFO UAP claimed crash-retrieval program?”
Davis’s answer: “I’ve always thought that the answer is yes to that question.”
Whether Weinstein is right about all of this – about the deliberate suppression of physics, about the institutional archaeology, about Renaissance Technologies – is less important than the fact that he is asking the questions at all. He brings a level of analytical depth to this space that it has never had. He is paying a professional price for it. And the questions he is raising about the history and sociology of physics are worth serious investigation regardless of what anyone believes about UFOs.
