Daniel Whiteson, a particle physicist at CERN, discusses his career searching for dark matter, the nature of particle colliders, the evidence for dark matter and dark energy, and the biggest open questions in physics — from quantum gravity and black holes to the simulation hypothesis, consciousness, and the future of scientific funding.
Particle colliders and the search for dark matter
Whiteson has spent his career at particle colliders, moving from Fermilab’s Tevatron to CERN’s Large Hadron Collider (LHC) because higher energy lets physicists probe deeper into what the universe is made of.
His primary goal at CERN was to produce dark matter in proton collisions; if dark matter is a particle that interacts with ordinary matter, it would appear as missing momentum — an imbalance where visible particles recoil against something invisible.
Colliders are not chemistry (rearranging existing pieces) but alchemy: the colliding protons annihilate into a high-energy intermediate state that can produce any particle nature allows, revealing “what’s on nature’s menu” without needing to know in advance what to look for.
After ~10 years searching with increasingly clever methods, no dark matter signal appeared; Whiteson shifted focus to looking for any unexpected anomaly in the data.
Evidence for dark matter and what it might be
Dark matter’s existence is supported by ~9 independent lines of evidence: galaxy rotation curves (stars orbit too fast for visible mass to hold them), cosmic microwave background ripple patterns (dark matter’s gravity shaped early density fluctuations), large-scale structure formation (not enough time for galaxies to form without extra gravity), gravitational lensing, and more.
It has mass and feels gravity but does not interact electromagnetically (no light emission/absorption); gravity alone is far too weak to detect individual dark matter particles (a fridge magnet overcomes Earth’s entire gravitational pull).
The leading assumption is that dark matter is a particle (or particles), but this is an extrapolation from the 5% of the universe we know; it could be something radically different — e.g., a smooth, non-particulate medium, or primordial black holes formed before particles existed.
Direct detection experiments (e.g., xenon detectors in Italy) wait for dark matter “wind” to nudge a nucleus; none have succeeded yet, suggesting the need for more creative theoretical and experimental approaches.
Dark energy, accelerating expansion, and energy non-conservation
In 1998–2001, supernova surveys revealed the universe’s expansion is accelerating — a “secret option C” beyond the two expected futures (eternal slowdown or big crunch).
Dark energy (~70% of the universe’s energy density) has constant density as space expands, so total dark energy increases; this drives runaway acceleration and means energy is created cosmologically.
Conversely, photons redshift as space stretches, losing energy that simply disappears — energy is also destroyed. Conservation of energy holds only in a static universe; ours is expanding, so the assumption fails.
A recent paper (Yonsei University, Aug 2026) questions the supernova distance calibration, suggesting acceleration might have transitioned to deceleration; this exemplifies open scientific scrutiny — multiple independent lines of evidence (CMB, baryon acoustic oscillations) still support acceleration.
James Webb Telescope and early galaxy surprises
JWST’s infrared vision sees galaxies forming far earlier than standard models predict — massive, mature galaxies appear when the universe was only ~250–400 million years old.
This doesn’t change the age of the universe or the Big Bang timeline (which describes the hot dense state ~13.8 Gya, not a “beginning” singularity), but it reveals gaps in galaxy formation theory.
Related puzzle: supermassive black holes at galaxy centers grew to billions of solar masses too quickly; primordial black holes (formed in the ultra-dense early universe) could seed them and also constitute dark matter — but we’ve never seen one evaporate via Hawking radiation.
Black holes, quantum gravity, and string theory
The central theoretical conflict: general relativity (smooth spacetime, gravity) vs. quantum mechanics (discrete, probabilistic) — they give contradictory predictions inside black holes.
Hawking radiation predicts black holes glow and evaporate, ending in a bright flash; tiny black holes would evaporate fast and visibly. CERN searched for micro black holes (produced in collisions) to test this and probe quantum gravity — cosmic rays already hit Earth at far higher energies, so no planetary risk.
String theory is the only mathematically consistent quantum gravity framework, but it’s extremely hard to test; alternatives include loop quantum gravity (spacetime as discrete pixels) and Eric Weinstein’s “Geometric Unity.”
Progress in fundamental physics over 70 years is real (Standard Model, neutrino masses, Higgs, gravitational waves) even if it hasn’t followed the “unification” narrative some expect.
Propulsion: ion drives and propellantless claims
Ion drives accelerate ions electrically, achieving high efficiency (kg of fuel to Mars vs. tons for chemical rockets) but low thrust — useful in space, not for launch.
A NASA electrostatics veteran (Charles Buhler) and an aerospace partner claim an “Exodus” drive producing thrust without expelling propellant, using electrostatic field interactions; they’ve demonstrated it in vacuum chambers and publish openly.
Such claims (like the earlier EM drive) face skepticism: conservation of momentum is a bedrock principle, and independent verification is essential. If real, it would revolutionize in-space transport but not solve interstellar travel (still limited by light speed).
Voyager, the Golden Record, and alien communication
Voyager 1/2 (launched 1977) are just beyond the heliopause — nowhere near another star; they carry the Golden Record (sounds, images, a hydrogen-spin “clock” diagram) and the Pioneer plaque (naked humans, pulsar map).
Whiteson tested the Pioneer plaque on physics PhD students — none decoded it; the assumptions about alien cognition (visual, mathematical, hydrogen-centric) are likely hopeless without shared context.
Spielberg’s “Disclosure Day” movie assumes government secrecy to prevent panic; Whiteson doubts both the secrecy (impossible at scale) and the panic motive — more likely incentives involve technology/military advantage.
UAPs, the VASCO study, and nuclear correlations
Navy pilot videos (Tic Tac, Gimbal, Go Fast) remain fuzzy and inconclusive; a Congress member who saw classified footage told Whiteson the unreleased videos show nothing more compelling.
The VASCO project (Beatriz Villarroel) found ~100,000 transient “mirror-like” objects on 1950s Palomar photographic plates — before Sputnik — that appear/disappear with Earth’s shadow, suggesting orbital reflectors; some correlate statistically with nuclear test timing.
Critics argue plate artifacts (dust, emulsion flaws) dominate the signal; a reanalysis claimed the correlation vanishes with better cleaning. The debate is open and scientific — exactly how it should be.
UFO sightings cluster culturally (mostly US), and correlation ≠ causation (e.g., Netscape usage vs. murder rates); extraordinary claims require physical evidence, not stories.
Simulation hypothesis, error-correcting codes, and consciousness
Jim Gates (MIT) found structures in supersymmetric string theory equations identical to Claude Shannon’s 1940s error-correcting codes; he presented this to Neil deGrasse Tyson as “computer code in the fabric of the cosmos.”
Whiteson cautions: even if our universe is a simulation, its rules need not resemble the “outer” universe’s physics (Super Mario learns nothing about our physics from his game engine); the code resemblance may be pattern-matching, not evidence.
Panpsychism (consciousness as fundamental, everywhere) and integrated information theory attempt to explain consciousness, but it remains unmeasurable — we infer others’ consciousness but have no data; it may take centuries to become a scientific question.
Telepathy is not physically forbidden (brains emit/detect EM fields), but no rigorous evidence exists; facilitated communication studies are methodologically shaky; psychedelics amplify pre-existing beliefs (John Hopkins study with religious leaders), acting as a “placebo for the inner psyche.”
AI in science: accelerator, not replacement
AI excels at cross-disciplinary synthesis (e.g., finding mathematical tools that solve physics problems, as Einstein did with differential geometry) — it reads all literature instantly and translates jargon.
In mathematics, AI has solved open problems by connecting known results; in physics, progress is slower due to fuzzier, intuition-driven problem framing.
AI will not replace human curiosity — it answers today’s questions, inspiring tomorrow’s; scientists remain the question-askers. Bias in training data is inevitable; private control of AI infrastructure raises governance concerns.
Privatization, NASA funding, and the Genesis Project
NASA’s budget fell from ~4.5% of federal spending (Apollo era) to ~0.4% today; science missions (Europa lander, interstellar probes) are starved while launch privatization (SpaceX) dominates.
The 2025 “Genesis” executive order redirects existing DOE/national lab funds to private AI companies (OpenAI, Google, Microsoft, etc.) in a closed-loop “AI Manhattan Project” — outsourcing fundamental research, reducing public oversight and academic freedom.
Whiteson argues basic research has enormous ROI (transistors, lasers, internet) and should be publicly funded in addition to AI partnerships, not replaced by them.
Future colliders, gravitational waves, and interstellar objects
Next-gen colliders (FCC, ~$50–100B) face diminishing returns; Whiteson favors investing in new acceleration technology (plasma wakefield) to make colliders lab-scale and affordable.
LIGO detected gravitational waves (2015); LISA (space-based, 2030s) will use three laser-linked satellites to hear mergers from the earliest universe — gravitational waves pass through everything, offering a “fetal ultrasound” of the cosmos.
Pan-STARRS (Hawaii) and ATLAS (Chile) now detect interstellar objects (ʻOumuamua, 2I/Borisov, etc.) — we’ve only seen a handful, but they arrive often enough to build a statistical sample of material from other stars.
Closing reflections
The universe constantly surprises us (dark energy, early galaxies, gravitational waves); every new observational window reveals “secret option C.”
We ignore almost all cosmic information (photons hitting sidewalks); 10× more space telescopes would be transformative and cheap relative to societal spending.
Science is a human endeavor — curious, messy, political — but it works because data ultimately adjudicates. The biggest mysteries (dark matter, quantum gravity, consciousness, aliens) remain open, and the next breakthrough will likely be something no one imagined.
