Brendan McNamara wants to meet aliens. Not in the abstract, not through a message that arrives centuries after it was sent, and not by launching a spacecraft that his distant descendants might eventually welcome home. He wants the encounter to happen within his own lifetime. An ecologist, computer technician, farmer, and carpenter, McNamara approaches that ambition from an unusually broad perspective, following a trail that leads from nuclear propulsion and engineered spacetime to quantum computers, simulated worlds, and consciousness itself. Along the way, the question changes. What begins as a search for a faster spacecraft becomes something more fundamental: Does experiencing another world necessarily require taking a human body there?

The Problem Isn’t Just Distance. It’s Time.

“Space is big,” McNamara says, introducing the obstacle that every interstellar transportation proposal must confront. Light travels at roughly 186,000 miles per second, yet the distances between stars are large enough that astronomers describe them in years of light travel. In his opening comparison, McNamara uses a journey of approximately 4.4 light-years and a conventional rocket travel time of about 30,000 years. It’s a broad illustration rather than a calculation for a particular mission, but the contrast captures his frustration. Reaching another star and reaching it while the original passengers are still alive are very different objectives.

His survey begins with propulsion systems that attempt to improve how spacecraft produce and use thrust: ion and plasma engines, nuclear fission and fusion, and sails driven by sunlight or lasers. The sail concept replaces an exhaust stream with the pressure of light striking a reflective surface. McNamara’s concern is what happens when the payload becomes a person rather than a small instrument package. The reflecting surface, the available light, and the mass being transported all become part of the problem. Antimatter propulsion offers another possibility, potentially transferring energy from powerful reactions to a vehicle through a pusher plate or a structure behind the spacecraft. But extraordinary energy doesn’t automatically produce an acceptable human travel time.

Other proposals address the passengers instead of sufficiently shortening the journey. A generation ship would carry a civilization whose descendants complete the voyage. Cryogenic suspension would attempt to preserve the travelers while the years pass around them. A genetic ark would go further, carrying DNA, biological information, and raw materials with the intention of reconstructing living systems at the destination. McNamara finds the contrast revealing: Rebuilding an entire biological expedition at another star can be discussed as an alternative to warp drive, even though it introduces enormous requirements of its own. Each approach solves the lifetime problem by changing who—or what—actually arrives.

Robotic probes remove the need to transport a human habitat, but they introduce a different set of demands. McNamara emphasizes the intelligence and durability required for a machine to survive the journey, accomplish its mission, and return useful information. Self-replicating von Neumann probes would extend that strategy by manufacturing additional explorers, allowing successive generations of machines to spread outward. Such systems could make humanity an interstellar presence without making individual humans interstellar travelers. That’s the distinction he keeps returning to. His benchmark isn’t simply whether a technology can cross the distance, but “how do we get there in a single human lifetime?”

Engineering the Space Around the Ship

McNamara’s search turns toward warp drives when conventional acceleration appears unable to deliver the experience he’s seeking. As a massive object approaches light speed, he explains, its energy requirements rise steeply. A warp concept changes the proposed task: Instead of forcing a spacecraft ever faster through space, it would manipulate the geometry surrounding the craft. Alcubierre’s 1994 proposal is his central reference point, bringing a familiar science-fiction idea into a mathematical framework involving spacetime compression and expansion. For McNamara, its significance is that the discussion can begin with equations rather than remain entirely within fiction.

The difficulty is turning a desired geometry into something a machine could produce. McNamara describes Alcubierre’s original concept as burdened by extreme energy requirements and exotic negative-energy conditions. He’s especially interested in subsequent proposals that try to reduce those demands or approach the problem through a different physical framework. The distinction between a mathematical model and an engineered vehicle is essential here. His presentation isn’t a report of a functioning faster-than-light spacecraft. It’s a survey of attempts to identify what would have to be controlled, supplied, or manufactured before such a craft could become an engineering project.

Salvatore Pais supplies one of the more elaborate possibilities in that survey. McNamara describes a proposed craft using microwave emitters to turn xenon gas into plasma, then manipulating that plasma through carefully varied frequencies, vibration, and rotation. The intended result is an asymmetric, nonequilibrium condition associated with extremely high energy densities. In the proposal as McNamara presents it, those conditions would affect spacetime or the surrounding vacuum, creating a route to unconventional propulsion. What attracts him is the ambition to obtain an unfamiliar result through a new arrangement of known physical ingredients. He summarizes the outlook with a phrase he attributes to Pais: “new engineering, not new physics.”

Jack Sarfatti’s low-power warp concept moves the emphasis toward metamaterials. McNamara describes engineering electric permittivity and magnetic permeability—epsilon and mu—to alter a material’s optical behavior and, in the proposed framework, reduce the power needed for spacetime manipulation. He calls this “front-loading the work into optical metamaterials,” shifting some of the burden from operating power to material design. He also describes a proposed observational signature: redshifting at a craft’s leading edge and blueshifting at its trailing edge. McNamara mentions UAPX and the Galileo Project as possible audiences for that prediction. It’s a suggested connection between a theoretical mechanism and an observable effect, not a confirmed identification of warp propulsion.

Could a Warp Drive Begin With a Material?

The appeal of materials-based approaches is that they offer something more tangible than an entire starship. McNamara’s broader survey includes Todd Desiato’s work connecting warp concepts with Maxwell’s equations, Hal Puthoff’s polarizable-vacuum framework, and alternative bubble geometries intended to improve the energy requirements of earlier models. He also discusses Mike McCulloch’s quantized inertia, while acknowledging that it isn’t conventionally described as a warp drive. What interests him is its proposed relationship between an object and the wider universe, particularly the possibility of reducing the effects of inertia. These ideas don’t constitute a single theory, but they share his interest in changing the conditions of motion rather than simply producing more thrust.

At a much smaller scale, McNamara points to work associated with Sonny White involving nanoscribed structures and Casimir cavities. He describes tiny, engineered features whose collective behavior might eventually matter at a larger scale. His imagined progression is from an individual cavity to a surface covered with many such structures, with the hope that their combined effects could influence spacetime. He’s also intrigued by using artificial intelligence to design and optimize those features. Rather than asking a human engineer to choose every microscopic shape, an automated process could search for arrangements suited to a desired effect. The proposed step from nanoscale structures to macroscopic propulsion is what makes the idea exciting to him—and what still needs to be established.

He finds another possible connection in T. Townsend Brown’s asymmetric-capacitor work. Drawing on the energy-density interpretation he associates with Puthoff, McNamara suggests that an electrostatic effect and a full warp drive might represent different scales of a related phenomenon. In that picture, carefully arranged electrical conditions would produce variations in spacetime, with a much stronger manifestation eventually becoming useful for propulsion. This is McNamara’s proposed connection, not an experimentally demonstrated equivalence presented in the interview. Its attraction is nevertheless clear: It would connect the starship problem to devices involving electrodes, materials, and laboratory-scale measurements, rather than requiring researchers to begin with the complete vehicle.

Software offers another way to make the problem more concrete. McNamara highlights Warp Factory for turning mathematical spacetime descriptions into three-dimensional visualizations, allowing researchers to inspect proposed geometries rather than encounter them only as equations. He also mentions a stable-matter-shell model as an example of efforts to improve a warp proposal’s physical requirements. His enthusiasm centers on the possibility of working through a design: examining its geometry, understanding where its requirements arise, and comparing it with alternatives. A visualization isn’t a manufactured spacetime bubble, but it can make the assumptions and demands of a proposal easier to see. For McNamara, that’s a meaningful step toward asking better engineering questions.

Wormholes and the Possibility of Other Earths

A warp bubble would change the spacetime around a traveling vehicle. A wormhole offers a different imagined solution: connect the destination and departure point through a shortcut. McNamara begins with Einstein and Rosen’s 1935 work, then moves to the ER = EPR conjecture associated with Leonard Susskind and Juan Maldacena. He’s drawn to the proposed relationship between spacetime connections and quantum entanglement. In his presentation, the important possibility is that a discussion usually illustrated with black holes might have implications for quantum-scale systems. The bridge between distant places might not have to begin as something large enough to fly a spacecraft through.

That possibility leads him toward quantum computers. McNamara discusses wormhole-related modeling as a potential application of quantum computation, then asks whether microscopic connections could someday carry information across space and time. He extends the idea to the complex circuitry of computers and, more speculatively, to biological minds. A model of a wormhole-related system isn’t itself a communications link to another star, and his presentation doesn’t supply such a link. What interests him is the possible transition between those stages: whether a relationship investigated mathematically or computationally could eventually become something that engineers deliberately control.

Faster-than-light travel also leads McNamara into questions about causality. He uses the 45-degree light boundary in a spacetime diagram to introduce the implications he associates with going beyond ordinary light-speed travel, including backward time travel. From there, he moves into a further conjecture: access to alternative histories or branches of the universe. He draws on the many-worlds interpretation, mentioning Sean Carroll as one of its popular explainers, and imagines that technologies capable of manipulating spacetime might allow travel between different versions of Earth. That’s an additional speculative step in his argument, rather than an engineering capability established by the warp or wormhole models themselves.

His ecological background gives these alternative Earths a distinctive appeal. A planet around another star could possess atmospheric chemistry, microorganisms, and biological systems unlike anything humans evolved to tolerate. McNamara wonders whether another branch of Earth’s history might offer a closer environmental match. His example is a world where the dinosaurs didn’t disappear and troodons eventually developed into an advanced humanoid lineage. Such a destination would be familiar in some respects and radically unfamiliar in others. Its supposed biological compatibility is part of the thought experiment, not a demonstrated safety advantage. But it changes the map he’s imagining: The most interesting destination might be another history of this world, rather than another planet across the galaxy.

What If Consciousness Does the Traveling?

McNamara’s next possibility removes the spacecraft from the center of the story. He calls it “mental travel,” bringing together altered states of consciousness, proposed quantum processes in the brain, and hypothetical microscopic spacetime connections. His reference points include the Navigators of Dune, the tesseract in A Wrinkle in Time, astral projection, and remote viewing. He also points to religious accounts of extraordinary travel and bilocation. These references serve different purposes—fictional illustrations, historical narratives, personal reports—but they share a question he wants to pursue: Could a person experience another location without moving a body through the intervening distance?

For a possible molecular connection, he invokes Terence McKenna’s image of psychedelic compounds fitting into the brain’s machinery like a disc entering a jukebox. McNamara links that analogy to suggestions involving electron spin resonance and altered conscious states. He also recounts an anecdote from Jeremy Narby’s The Cosmic Serpent, describing imagery from ayahuasca experiences that was interpreted as resembling cellular structures and processes. In his retelling, the examples include organelles and chromosomes undergoing division. He treats such accounts as prompts for investigation, not as a completed explanation of how information would reach the brain. The unresolved issue is whether an experience contains independently verifiable information, rather than imagery that can be interpreted afterward.

His search for a framework ranges across Bernardo Kastrup, Donald Hoffman, Rupert Sheldrake, Roger Penrose, and Stuart Hameroff. McNamara draws these figures into a discussion about the relationship between consciousness and physical reality, with particular interest in Hameroff’s work on neuronal microtubules. He highlights suggestions about their optical and quantum properties and asks whether those properties could matter to conscious experience. The attraction is a possible connection between a biological structure and the larger spacetime questions already under discussion. But identifying quantum or optical behavior in a structure would still leave the central travel question unresolved: What, exactly, would connect an internal experience to a distant external place?

McNamara recognizes that verification is the crucial hurdle. He asks how researchers could develop shared methods for evaluating mental-travel experiences, and whether brain-computer interfaces might eventually help capture or compare what people experience. His discussion moves from computer control through a neural interface to the much more ambitious possibility of recording dreams or other internal states. Even a detailed recording, however, would have to be compared with something outside the participant’s mind to test a claim of remote access. A vivid experience and an accurate account of an independently observed location are different achievements. The distinction is where his exploration of consciousness would have to become a testable research program.

Building an Alien World Inside a Computer

Simulation provides a more direct route to an experience of somewhere else. McNamara points to SpaceEngine, No Man’s Sky, and Subnautica as examples of software that lets people explore planetary environments, imagined organisms, and unfamiliar ecosystems. He’s especially interested in procedural generation: creating environments through rules and computational processes rather than manually constructing every detail. Combined with speculative biology and evolution, that approach could produce worlds with their own environmental conditions and imagined developmental histories. The result wouldn’t have to be a static backdrop. It could be a place whose features emerge as the participant explores it.

Generative AI would make the environment more responsive, while a brain-computer interface could potentially change how someone interacts with it. McNamara imagines a system that takes real-time input, generates an experience around that input, and returns feedback to the participant. He mentions Neuralink as one possible reference point for the interface, while leaving the larger system hypothetical. In his vision, the participant wouldn’t simply watch an alien landscape on a display. They would explore it, encounter its inhabitants, and perhaps receive help interpreting unfamiliar languages. The ambition is to combine world-building, adaptive intelligence, and direct interaction into something that feels less like viewing a simulation and more like being somewhere.

Quantum computing gives the idea a more controversial extension. McNamara favors a many-worlds reading of quantum computation and argues that some quantum simulations involve performing physical quantum processes rather than merely representing them digitally. From there, he wonders whether a sufficiently sophisticated simulated world might correspond to something that exists elsewhere in an effectively limitless cosmos. That correspondence is his extrapolation; he doesn’t present evidence that generating a plausible world establishes contact with a real one. Nevertheless, it’s central to the way he frames the problem. He’s interested in whether the boundary between constructing an experience and discovering something could become harder to draw.

His computing survey also includes analog approaches, NVIDIA graphics processors, and the specialized language-processing hardware he associates with Groq. These aren’t presented as a settled architecture for an interstellar interface. They’re examples of the different computational approaches he expects to contribute to richer generated experiences. More capable hardware could support more detailed environments, more responsive interactions, and more elaborate artificial inhabitants. For McNamara, that development raises the next question rather than settles the last one: When a simulated world becomes convincing enough to explore, learn from, and form relationships within, what would establish whether it’s only a construction—or something connected to a reality beyond its machinery?

A Universe Inside a Universe

Black holes take that question to its most expansive form. McNamara invokes ideas he associates with Stephen Hawking about black holes and information, using a storage-device analogy to describe information persisting even when matter loses its recognizable form. In his telling, a black hole’s surface becomes a way to imagine an information-bearing physical system rather than merely a place where familiar objects disappear. He then asks what such a system might be capable of containing or supporting. It’s a conceptual starting point for his speculation about simulated realities, not a design for a computer that uses a black hole.

From there, he imagines nested worlds: a reality inside a larger information system, with additional simulations developing within it. Humanity’s own universe might occupy one level, while other simulated environments exist inside or alongside it. McNamara doesn’t provide a mathematical construction or observational result establishing that arrangement. Instead, he uses it to reconsider the assumptions people bring to simulation. A simulated environment, in this picture, wouldn’t necessarily be a small, isolated imitation. It might be part of a much larger structure whose inhabitants understand only the portion they can access.

That possibility loops back to the materials and spacetime engineering discussed earlier. McNamara asks whether the ability to manipulate spacetime would have applications beyond transportation. If engineered structures could control gravitational conditions, could they also help create simulations associated with a gravity well? It’s a substantial leap beyond the propulsion concepts, and he doesn’t supply a machine design or operating requirements for it. But the connection is important to his overall vision. A technology initially pursued to move a traveler might instead become a way to construct—or gain access to—the environment that the traveler experiences.

The identity of the observer then becomes part of the problem. Would an apparent visitor be a physical inhabitant of another world, someone accessing a shared environment, or an entity involved in operating the system? Could simulated worlds connect, and would their inhabitants recognize the connection for what it was? McNamara offers these possibilities as questions, not explanations established for reported encounters. “Where does it connect and how real is it exactly?” he asks. By this stage, his race toward the stars has become an inquiry into what makes a destination real, what makes an encounter genuine, and how either could be recognized from inside the experience.

The Internet of Experience

The idea that brings McNamara’s different routes together is an “internet of experience.” Transporting a person means moving a biological organism and everything necessary to sustain it. A remote encounter would instead depend on exchanging information and creating a shared experience from that information. Moving data doesn’t, by itself, eliminate interstellar travel times or establish faster-than-light communication. But it changes the mission he’s trying to accomplish. The goal would no longer be delivering a passenger to another planet. It would be giving that passenger a meaningful way to interact with another place—and perhaps another intelligence—without physically arriving there.

The communication channel is the missing piece. McNamara discusses proposed gravitational-wave communication, describing an envisioned conversion between electronic signals and gravitational signals. He imagines high-bandwidth information packages capable of passing through obstacles and connecting distant systems. He also returns to counterportation, which he places within his discussion of quantum computers and hypothetical microscopic spacetime connections. The interview doesn’t provide demonstrated transmission distances, bandwidth figures, or an operating interstellar network. These are the proposed ingredients of the system he wants to imagine. For the experience to represent contact rather than simulation alone, some channel would have to connect the participant with an independently existing destination.

The social interface, by contrast, is easy to picture. McNamara compares it to friends meeting inside Call of Duty, Battlefield, or Halo, except that the participants could be separated by astronomical distances. Instead of exchanging emails, they might project three-dimensional avatars into one another’s surroundings or meet within a shared digital environment. High-resolution images, dense acoustic information, and perhaps even digitally conveyed feelings would make the encounter increasingly immersive. He speculates that some apparent visitors might themselves be remotely operated representations, though he offers no evidence establishing that explanation. In his most optimistic scenario, there are “other players in the game just waiting for us to log on.”

McNamara closes with a more familiar transition: the move from 56K connections to cable, DSL, and ever-greater bandwidth. People didn’t leave that new capacity unused. They developed experiences that took advantage of it. “We fill the gap,” he says. He imagines the same impulse carrying humanity toward increasingly responsive worlds, more direct interfaces, and eventually forms of contact that might not resemble a spacecraft landing on another planet. Whether any of those routes reaches beyond simulation remains unresolved. But the personal ambition beneath his survey never changes. McNamara wants to experience what lies beyond Earth while he still has a lifetime left to experience it. The race isn’t simply to build a faster engine. It’s to find a way across.
