Hal Puthoff

Harold Edward Puthoff (/ˈpʌthɒf/; born June 20, 1936), commonly known as Hal Puthoff, is an American physicist, electrical engineer, and parapsychologist known for directing classified remote viewing research for the Central Intelligence Agency and Defense Intelligence Agency at SRI International for more than two decades, for theoretical work on zero-point energy, stochastic electrodynamics, polarizable vacuum physics, and quantum vacuum propulsion at the Institute for Advanced Studies at Austin, and for his role as senior physics advisor on the government-funded UAP programme that preceded the Advanced Aerospace Threat Identification Program (AATIP). He is a co-founder of To the Stars Academy of Arts and Sciences with musician Tom DeLonge.

Early life and education

Puthoff was born in Chicago, Illinois, on June 20, 1936. He received a BA and an MSc in electrical engineering from the University of Florida. Between his master's and doctoral studies he served as a naval intelligence officer at the National Security Agency, accumulating high-level security clearances that would later draw him into classified research.

In 1967, Puthoff earned a PhD in electrical engineering from Stanford University with a thesis on the stimulated Raman effect and its application as a tunable laser. As a graduate student he co-invented a broadly tunable infrared laser, obtained a patent, and co-authored Fundamentals of Quantum Electronics with his thesis advisor Richard H. Pantell — a graduate textbook published in English, French, Russian, and Chinese. Puthoff also published early papers on polarizable vacuum and stochastic electrodynamics.

Scientology involvement

Puthoff took an interest in the Church of Scientology in the late 1960s and reached the then-top OT VII level by 1971. He wrote up his "wins" for a Scientology publication, claiming to have achieved remote-viewing-like abilities (called exteriorization in Scientology). In 1974 he wrote a piece for Scientology's Celebrity magazine, stating that Scientology had given him "a feeling of absolute fearlessness". Puthoff severed all connection with Scientology in the late 1970s.

Remote viewing research at SRI

After moving to SRI International to continue laser research, Puthoff's questions about consciousness and anomalous biological effects led him toward what became a career-defining detour. After encountering the work of polygraph researcher Cleve Baxter on anomalous plant responses, Puthoff invited self-described psychic and artist Ingo Swann to SRI for informal experiments. Swann allegedly demonstrated ability to affect and accurately describe the interior of a multiply-shielded quantum chip at SRI — drawing an unpublished diagram of its internal schematics — which, according to Puthoff, prompted the Central Intelligence Agency to approach him directly.

The CIA awarded Puthoff an initial contract of roughly $50,000–60,000; working alongside physicist Russell Targ, he built this into a research programme lasting over two decades. In the 1970s and 1980s, Puthoff directed the programme at SRI to investigate paranormal abilities, collaborating with Targ in studies of the purported psychic abilities of Uri Geller, Ingo Swann, Pat Price, Joseph McMoneagle and others, as part of what became known as the Stargate Project. The programme enrolled viewers including Swann, former Burbank police commissioner Pat Price, and Army intelligence officer Joe McMoneagle.

Operational results

CIA contract monitors tasked Price against coordinates adjacent to Sugar Grove Station, a highly classified NSA facility intercepting Soviet satellite communications; Price reportedly described classified project titles he claimed to have read from a safe inside the building, prompting a law-enforcement investigation into how the information was obtained. McMoneagle purportedly described a then-unknown giant titanium submarine under construction at a Soviet R&D facility near Semipalatinsk; according to Puthoff, satellite imagery later confirmed his sketches, which received briefings to the National Security Council. In an operational application disclosed years later by President Jimmy Carter, two remote viewers allegedly placed a location within three miles of a downed Soviet Tu-22 aircraft somewhere in Africa, enabling a US recovery team to retrieve it before Soviet forces arrived.

Experiments placing viewers aboard submarines at depth purportedly established that the effect persisted through seawater, ruling out low-frequency electromagnetic transmission as the mechanism. Puthoff and Targ published unclassified findings in the Proceedings of the IEEE in 1976, after a successful replication at Bell Labs supported peer review; the PEAR Lab at Princeton under Robert Jahn subsequently replicated the remote-viewing results independently, per Puthoff. McMoneagle reportedly received the National Intelligence Meritorious Award for more than 200 sanctioned viewings for the CIA, NSC, and FBI.

Mainstream scientific critiques

Puthoff and Targ's conclusions were contested in the scientific mainstream. Both Geller and Swann convinced Puthoff and Targ that they possessed psychic powers, though critics have argued Geller employed sleight of hand tricks rather than genuine paranormal ability. According to Terence Hines:

Geller turned out to be nothing more than a magician using sleight of hand and considerable personal charm to fool his admirers. The tests at SRI turned out to have been run under conditions that can best be described as chaotic. Few limits were placed on Geller's behavior, and he was more or less in control of the procedures used to test him. Further, the results of the tests were incorrectly reported in Targ and Puthoff's Nature paper.

Psychologists David Marks and Richard Kammann attempted to replicate Puthoff and Targ's remote viewing experiments in thirty-five studies and could not replicate the results. Examining the procedure of the original experiments, Marks and Kammann found that the notes given to the judges contained clues as to which order sessions were carried out — such as references to prior days' targets or session dates written at the top of the page — and concluded that these clues explained the high hit rates. Hines further wrote:

Examination of the few actual transcripts published by Targ and Puthoff show that just such clues were present. To find out if the unpublished transcripts contained cues, Marks and Kammann wrote to Targ and Puthoff requesting copies. It is almost unheard of for a scientist to refuse to provide his data for independent examination when asked, but Targ and Puthoff consistently refused to allow Marks and Kammann to see copies of the transcripts. Marks and Kammann were, however, able to obtain copies of the transcripts from the judge who used them. The transcripts were found to contain a wealth of cues.

Marks noted that when the cues were eliminated the results fell to chance levels. James Randi noted that controlled tests by several other researchers, eliminating sources of cueing and extraneous evidence present in the original tests, produced negative results; students also solved Puthoff and Targ's locations from the clues that had inadvertently been included in the transcripts. Marks and Kammann concluded: "Until remote viewing can be confirmed in conditions which prevent sensory cueing the conclusions of Targ and Puthoff remain an unsubstantiated hypothesis." According to Martin Gardner, Puthoff and Targ "imagined they could do research in parapsychology but instead dealt with 'psychics' who were cleverer than they were".

Institute for Advanced Studies at Austin and EarthTech

In approximately 1985, Puthoff departed SRI and moved to Austin, Texas, founding the Institute for Advanced Studies at Austin (IASA) to pursue theoretical physics, later incorporated under EarthTech International, Inc., in 1991.

In 1998, Puthoff and EarthTech were granted a US Patent with claims that information could be transmitted through a distance using a modulated potential with no electric or magnetic field components. While "the invention does appear to rest on solid, albeit somewhat obscure, physics principles", the case is used for educational purposes in patent law where "the examiner failed to make a prima facie case for inoperability or lack of enablement".

Zero-point energy research

At the Institute for Advanced Studies at Austin, Puthoff developed theoretical frameworks linking zero-point energy and quantum vacuum physics to potential propulsion applications. According to Puthoff, empty space is permeated by quantum fluctuations whose aggregate energy density is — by standard quantum field theory — some 120 orders of magnitude greater than other cosmological constraints would allow, and if these fluctuations could be de-randomised and coherently accessed, the vacuum could in principle function as an energy source.

In the late 1980s and 1990s, Puthoff co-authored papers using the model of stochastic electrodynamics leading to a model of inertia as an electromagnetic drag force on accelerating particles produced by interaction with the zero-point field. This concept built on Andrei Sakharov's 1968 proposal that the gravitational constant was a consequence of zero-point fluctuations in the vacuum. Working with colleagues including researchers from Lockheed Martin, Puthoff modelled inertia as an electromagnetic interaction with quantum vacuum fluctuations, with implications for antigravity propulsion.

Steve Carlip disputed one of Puthoff's 1989 papers, arguing it contained a serious computational error that made the proposed effect negligible; Puthoff responded that a different parameter value in the model would restore its usefulness. A 1994 paper by Puthoff was the subject of a news article in Science. Subsequent analysis by Yefim S. Levin raised numerous questions about the mathematical correctness of the formula and the use of non-relativistic treatments of magnetic effects, concluding that the model does not demonstrate inertia as a result of zero-point-field effects. The cosmological implications of a different 1989 Puthoff paper were examined by Paul S. Wesson: among numerous difficulties, general relativity requires that such energy not gravitate, so it cannot be similar to electromagnetic radiation.

Building on earlier theoretical work by Robert L. Forward leveraging the Casimir force to extract electrical energy, Daniel Cole and Puthoff analyzed the thermodynamics of a simple hypothetical Casimir-force device. The hypothetical devices discussed in these articles are capacitors — multiple layers of charged conductors sufficiently close for the short-range Casimir force to compress the structure against the mutual repulsion of the conductor's electrical energy stores; external electricity would be needed to recharge the device. Other authors have studied mechanical and thermal devices based on Casimir forces.

Massimo Pigliucci has characterized Puthoff's hopes of extracting zero-point energy as running contrary to the laws of physics: "a proposition... that violates basic principles of thermodynamics and that is considered pseudoscience by credentialed physicists."

Spacetime metric engineering and polarizable vacuum

NASA aerospace engineer Larry Lemke has described Puthoff's zero-point energy work as the most plausible physical explanation for certain UAP flight characteristics — specifically their alleged capacity to transit the atmosphere without generating sonic booms, turbulent wakes, or audible noise. Puthoff separately developed a spacetime metric engineering framework, applying Einstein's general relativity equations to catalogue anomalous UAP flight characteristics — right-angle hypersonic turns, apparent dimensional distortion near the craft, electromagnetic frequency shifts — and concluded that the same equations governing extreme astrophysical events would in principle account for these phenomena if sufficient energy were available to engineer the local metric.

In a 2024 American Alchemy roundtable with mathematician Eric Weinstein, Puthoff elaborated on his polarizable vacuum approach — a framework published in peer-reviewed physics journals — which treats the vacuum as a dielectric medium whose permeability (μ) and permittivity (ε) values are not fixed but can in principle be manipulated. Because the speed of light equals one over the square root of μ times ε, engineering those values would alter the local value of c and thereby modify every general-relativistic effect in that region, potentially producing the flight characteristics — silent hypersonic turns, apparent mass reduction — observed in UAP. In the same discussion, Puthoff disclosed that he holds two patents on engineering applications of vector and scalar electromagnetic potentials — fields that exert quantum phase-shift effects on charged particles even in the absence of detectable electric or magnetic fields — and has started a company built around these approaches.

UAP research

BAASS and the DIA contract

In the 1990s Puthoff began consulting for Robert Bigelow's Bigelow Aerospace Advanced Space Studies (BAASS) on UAP questions. When senators Harry Reid, Daniel Inouye, and Ted Stevens arranged DIA funding for a new UAP programme around 2008, Bigelow won the contract — formally the Advanced Aerospace Systems Applications Program (AASAP) — and engaged Puthoff to lead its physics and engineering assessment.

Puthoff's tasking was to assess the physics and engineering behind reported UAP capabilities and to attempt to negotiate access to recovered materials allegedly held by aerospace contractors; those negotiations were reportedly rebuffed on grounds that any such materials would be "too highly classified" to share even under existing top-secret SCI clearances. In response, Puthoff commissioned 38 technical papers from leading subject-matter experts across advanced propulsion, wormhole physics, warp drive, dark energy, extra dimensions, and related fields — framed as a 2050 technology forecast for Bigelow Aerospace, without disclosing the UAP context to contributors. The papers — known as the Defense Intelligence Reference Documents (DIRDs) — were posted to the classified JWICS server and later substantially released through Freedom of Information Act requests.

AATIP and Kona Blue

AATIP (the Advanced Aerospace Threat Identification Program), run by Luis Elizondo, continued UAP investigation after the Bigelow-held AASAP programme wound down around 2012. Puthoff subsequently joined a group that sought to establish a Special Access Programme at the Department of Homeland Security designated Kona Blue — a programme later confirmed publicly by the All-domain Anomaly Resolution Office (AARO).

To the Stars Academy

Before the December 2017 New York Times story that brought the Nimitz UAP footage to public attention, Puthoff joined Tom DeLonge and retired CIA officer Jim Semivan to found To the Stars Academy of Arts and Sciences.

Through To the Stars Academy, Puthoff was involved in having a sample of layered bismuth and titanium — purportedly debris from the Roswell crash, forwarded to radio host Art Bell by an Army veteran's descendant — analyzed by Oak Ridge National Laboratory under a contract brokered through an Army office and AARO. Per Puthoff, the analysis found no isotopic evidence of extraterrestrial origin but identified the micro-thin alternating laminate layers (some the width of a human hair) as having no precedent in the history of materials science; an aerospace contractor paid to replicate the bismuth-magnesium bonding reportedly spent over one million dollars producing only two bonded layers before its instruments failed.

In a 2024 appearance on American Alchemy with Jesse Michels, called in by phone while Garry Nolan displayed materials at the Nolan Research Lab at Stanford, Puthoff identified the provenance of a layered bismuth-magnesium sample as having been sent anonymously to his attention by someone claiming to be an Army officer who found it while going through his grandfather's archives, accompanied by a diary entry describing it as a piece from a UAP encounter. Puthoff stated that analysis of the material indicated it could function as a micro-scale waveguide at terahertz frequencies, reducing the effective size of a microwave carrier to approximately one-thirtieth of its standard wavelength — enabling thirty waveguides to occupy the space of one — a property he described as having no established application in conventional materials science at the time. In the same discussion, Puthoff was identified by Michels as one of the key members of what Nolan calls the "invisible college" — the network of scientists and intelligence figures who introduced Nolan to UAP research — alongside Jacques Vallée, Eric Davis, Robert Bigelow, and Colm Kelleher.

Michels described Puthoff's career to his audience as: "He was first a laser physicist, and then, out of Stanford Research Institute, he started the government's psychic spy program. Since then he's been doing frontier tech research and has briefed multiple presidents on UFOs."

Roswell and EMP hypothesis

In a SCIF conversation with Luis Elizondo, Puthoff allegedly reported that four deceased non-human bodies were recovered from the 1947 Roswell crash and that the incident was genuine. He hypothesized that the craft had been conducting reconnaissance on the nuclear weapons program when "an electromagnetic pulse generated from one of the nearby test ranges had inadvertently intervened with the craft's technology" — suggesting EMP could be "an Achilles' heel" for NHI propulsion systems (see Electromagnetic disruption of NHI craft (July 1947)).

UAP origin and non-disclosure

According to Puthoff, the United States has recovered more than ten non-human craft, and comparable recovery programmes exist in other countries. A George W. Bush-era briefing was reportedly convened at which participants — including former CIA personnel and military officers — evaluated the societal consequences of disclosing that the US, Russia, and China had obtained non-human craft and bodies; all working groups returned net-negative scores and concluded disclosure was inadvisable at the time.

Puthoff has authored a paper titled Ultra-terrestrials cataloguing competing hypotheses — spacecraft from distant galaxies, remnant civilisations from Earth's deep past, long-term off-world bases, and time travellers from humanity's future — without endorsing any single account. He has stated that non-human intelligence (NHI) is a real phenomenon, though its precise origin may remain above his former clearance levels.

On disclosure policy, Puthoff has cited Edward Teller's observation that unclassified electronics development far outpaced classified nuclear development during the Cold War, and has argued that current compartmentalisation around UAP programmes is counterproductive. He has participated in the Sol Forum of the Sol Foundation alongside Jacques Vallée and Larry Lemke, discussing UAP materials analysis, quantum vacuum propulsion, and the need for international scientific collaboration on UAP data.

Puthoff has also reported that parts of the government actively deploy stigma to protect UAP programs, citing a specific instance in which a component of the research programme was shut down by someone who argued that American taxpayer dollars "should not be spent on pursuing demonic technology."

Greer's allegations

In a separate interview, Steven Greer named Puthoff specifically as one of several individuals whose "job" was allegedly to divert researchers away from the truth about suppressed energy technologies, stating: "Hal Puthoff's job on energy. That's their job is to divert people into that dead end cul de sac." Greer noted Puthoff's intelligence and claimed that "one of his closest friends is on my team" and that Greer knew "exactly what they said and what they did to get him to do what he's been doing." Greer also alleged that Puthoff was "soliciting me for funds for his quantum communication thing, which I think the Navy has had for 30 years," characterizing the request as indicative of the "disconnects" within the TTSA circle between what was publicly presented as cutting-edge research and what Greer contended had already been operational in classified programs for decades.

Media appearances

Puthoff is a participant in The Age of Disclosure, a 2025 documentary film about UFOs and claimed government programs involving recovery of alien technology crashed on Earth.
