For most New Hampshire listeners who tuned into the latest episode of NHPR’s Cosmically Curious on Sunday morning, “warp speed” probably conjures the Enterprise streaking through space at impossible velocity, with Captain Picard issuing an order and the stars stretching into ribbons. The science fiction, it turns out, is not entirely fiction. Saint Anselm College physics professor Nicole Gugliucci spent two minutes on air explaining why a real, peer-reviewed line of theoretical physics has been quietly chasing the same idea for more than thirty years, and why a Granite State physicist thinks the math is at least worth taking seriously, according to NHPR’s Cosmically Curious episode published May 10, 2026.
The bottom line from Gugliucci is that a warp drive does not violate Einstein’s speed limit. It sidesteps it. The trick is not making a ship go faster through space. It is making space itself move around the ship.
The Idea That Made Warp Drive A Physics Paper, Not A Plot Device
The episode, hosted by NHPR’s Patrick McNameeKing, walked listeners through the basic intuition that turned the idea from a script gimmick into a serious theoretical physics problem. Gugliucci asked listeners to picture spacetime as a stretchy rubber sheet, or a carpet you can scrunch and pull. A conventional rocket tries to race across the carpet. A warp drive does something more interesting. It compresses the carpet in front of the ship’s bow and stretches it out behind the stern.
“By compressing space-time ahead and stretching it out behind, the ship essentially surfs on a moving wave of space itself,” is how the episode summarized her explanation. The vehicle inside the wave is not, in any local frame, going faster than light. The wave is moving the vehicle from one piece of space to another, and the vehicle is just along for the ride.
That distinction is doing the entire heavy lift in the physics. Special relativity, the framework Einstein laid down in 1905, says that nothing can move through space faster than light. It says nothing about how fast space itself can move, expand, or contract. The early universe, after all, expanded faster than light during cosmic inflation and continues to do so at the largest scales today, with no laws broken in the process.
A warp drive, in this conception, weaponizes that loophole. It does not try to win a race. It rewrites the track.
Where The Real Math Lives: The Alcubierre Concept
The reason this is a real branch of theoretical physics, and not just a screenwriter’s daydream, is a 1994 paper by Mexican physicist Miguel Alcubierre. Alcubierre showed that within Einstein’s own equations of general relativity, a particular configuration of energy and mass could in principle produce exactly the kind of compress-ahead and stretch-behind geometry the show was describing. He did not build anything. He did not propose a prototype. He simply demonstrated that the equations of the universe permit the geometry, the way the equations of arithmetic permit the answer to a multiplication problem you have not bothered to do yet.
That paper, more than any other single piece of work, is why “warp drive” has remained an active topic in physics seminars. It has been refined, criticized, and rebuilt by physicists at NASA, at Caltech, and at universities around the world for the better part of three decades. Gugliucci’s role on Cosmically Curious is to explain to a New Hampshire audience that the physics community takes the math seriously, even if no one is close to actually building a warp bubble.
She also explains, clearly and without overselling it, why nobody is close.
Exotic Matter And Negative Energy: The Reason There Is No Prototype
The warp bubble in Alcubierre’s paper requires a very specific kind of fuel. Compressing space in front of a ship and expanding it behind requires what physicists call exotic matter, a hypothetical substance with negative energy density. Ordinary matter, the kind everything you have ever touched is made of, has positive energy density. Negative energy density is something different.
“To warp space in such a way, scientists would need a massive object or a specific type of exotic matter that possesses negative energy,” Gugliucci told NHPR. “This is the playground of the theoretical physicist: probing the outer edges of known science to see where the math leads.”
There is a small caveat that keeps the door open. Quantum field theory does allow for tiny, localized regions of negative energy density under very specific conditions, in phenomena like the Casimir effect, where two uncharged metal plates placed extremely close together appear to attract each other through fluctuations in the quantum vacuum. Whether that effect can be amplified, harnessed, or shaped into the energy density a warp bubble would actually require is the question on which the entire theoretical project rests. The current honest answer is: we do not know, and most physicists suspect the answer is no.
Why A Saint Anselm Physicist Is The One Explaining This
Cosmically Curious has become one of the most consistent science-communication products in New Hampshire public media. The segment runs short, two to three minutes, and is built around explaining one specific astronomy or physics concept at a time. Gugliucci, who teaches physics at Saint Anselm College in Manchester, has become a recurring voice on the show alongside University of New Hampshire astronomer John Gianforte. Where Gianforte often handles questions about planetary science and observational astronomy, Gugliucci tends to take on the more theoretical and quantum-leaning questions, including the recurring listener requests about faster-than-light travel, multiverse cosmology, and the interpretation of strange experimental results.
Saint Anselm itself has been quietly building a profile in physics and applied science instruction. The Catholic liberal arts college in Goffstown, founded in 1889, hosts the Institute of Politics that has shaped New Hampshire’s first-in-the-nation primary culture, but it also produces working physicists, engineers, and educators. The college has hosted civics-focused student events that bring high schoolers from across the state to the campus, and its faculty members are regular contributors to public-facing science programming through partnerships like Cosmically Curious.
For the Granite State, having a working physicist on local airwaves explaining the actual content of theoretical physics, rather than handing the topic off to network television personalities, matters more than it might seem. New Hampshire’s college-bound students are inundated with viral science content built for engagement, not accuracy. A two-minute segment from a credentialed working physicist is a different product entirely. It models what it looks like to take a fantastical idea seriously without losing the rigor that made the idea worth investigating in the first place.
What Cosmically Curious Has Been Building Toward
Sunday’s episode is part of a longer arc. Earlier this month, the same segment featured John Gianforte explaining how subterranean ice on Mars and at the lunar south pole could be electrolyzed into rocket fuel, a concept the Granite State Review covered in its previous Cosmically Curious recap on Mars water and rocket propulsion. Cosmically Curious as a body of work has, episode by episode, been walking listeners through the practical and theoretical steps that lie between human spaceflight today and the kind of long-distance, multi-decade missions that fiction has assumed for half a century.
The Mars water episode established that humans could plausibly produce their own propellant on another planet, eliminating one of the largest mass constraints on a crewed Mars mission. The lunar south pole episode established that the same techniques could turn the moon into a refueling station for missions further out. The warp drive episode is, in effect, the next conceptual rung on the ladder. If chemical rocketry, even with off-world refueling, will not get a crew to a habitable exoplanet within a human lifetime, what physics, even speculative physics, might?
The honest answer Gugliucci offered is “not yet, and maybe not ever, but the math is interesting.” That is a more grown-up answer than most science programming gives.
The University Of New Hampshire Connection
Cosmically Curious was originally launched as a partnership with John Gianforte at the UNH Observatory in Durham, and the University of New Hampshire continues to be the institutional home for much of the segment’s astronomy content. UNH has built a serious profile in space-physics research over decades, with instruments contributed to multiple NASA missions and an active Space Science Center that focuses on solar wind, magnetospheric physics, and instrument development. The university’s recent groundbreaking on a new 70,500-square-foot UNH-NOAA mapping and research center in Durham is part of the same broader push to make New Hampshire a recognizable hub for federally connected research.
The pairing of UNH and Saint Anselm faculty on Cosmically Curious also reflects something practical about the New Hampshire higher-education landscape. The state’s research capacity is real but distributed. No single institution dominates the way Massachusetts Institute of Technology or Caltech do in their states. By drawing on faculty from multiple campuses, the segment essentially aggregates the expertise the way a single large research university would internally.
What Listeners Are Actually Hearing
The warp drive episode is two minutes and six seconds long. Listeners can email cosmic@nhpr.org with their own astronomy questions, and the show pulls from listener questions for upcoming episodes. The full archive is at the Cosmically Curious page on NHPR’s website. Sunday’s episode is currently available as on-demand audio, with a transcript and a short web write-up. The host, Patrick McNameeKing, has been producing the segment with NHPR’s news team and has progressively expanded the kinds of questions the show is willing to take on.
A New Hampshire audience that is willing to hear out a theoretical physicist explaining a sci-fi premise without dismissing it is, in its own quiet way, a public good. So is the underlying message: real physics is more interesting than the shows. The Enterprise was a metaphor. The Alcubierre paper is a real document, sitting in a peer-reviewed journal, and the question of whether the matter required to make it work actually exists is one of the genuine open questions of modern theoretical physics.
