The Infinite Pattern That Never Repeats
A centuries-old obsession with “regular” geometry turned into a real-world materials breakthrough: Penrose tilings—made from just two shapes—can fill...
The Edge of an Infinite Universe
The most consequential idea here is that “boundaries at infinity” aren’t just mathematical conveniences: in certain cosmologies they may function...
The Holographic Universe Explained
Black holes forced physics to confront a startling fact: the maximum amount of quantum information inside a region scales with the region’s surface...
Did Time Start at the Big Bang?
The Big Bang didn’t “start time” in the literal, clock-like way many people learn in school; in the standard Einstein general-relativity picture, the...
What if Singularities DO NOT Exist?
A new challenge to the idea that black holes must contain “real” singularities is gaining attention: Roy Kerr argues that the logic behind the...
What Happens After the Universe Ends?
The universe’s “end” may not be an ending at all: one leading, highly speculative framework—Conformal Cyclic Cosmology (CCC)—claims the far-future...
How The Penrose Singularity Theorem Predicts The End of Space Time
Roger Penrose’s singularity theorem delivers a stark conclusion: within Einstein’s general relativity, black holes are not just likely to form—they...
Is The Wave Function The Building Block of Reality?
Quantum mechanics allows particles to exist in superpositions—fuzzy bundles of possible properties that only become definite when measured. The...
Will Wormholes Allow Fast Interstellar Travel?
Wormholes remain a staple of science fiction, but the physics trail from Einstein’s earliest ideas to modern constraints points to one bottom line:...
What If The Universe DID NOT Start With The Big Bang?
The strongest takeaway is that modern cosmology still points toward a past boundary—often interpreted as a beginning of time—because geodesics in an...
The Gravity Particle Should Exist. So Where Is It?
The graviton—the hypothetical quantum particle that would mediate gravity—remains the missing piece needed to connect quantum mechanics with general...
Mapping the Multiverse
Rotating black holes don’t just swallow matter—they can act like gateways to a chain of causally disconnected regions of spacetime, complete with...
The Andromeda Paradox Even Confuses Physicists
The Andromeda paradox is a relativity puzzle about how “now” and simultaneity work when two observers move relative to each other—so much so that...
Was Penrose Right? NEW EVIDENCE For Quantum Effects In The Brain
Roger Penrose’s long-running claim that consciousness may depend on quantum physics is getting a fresh reality check—not because the brain has been...
Why Do You Remember The Past But Not The Future?
Physics treats time as directionless: the equations governing motion run just as well backward as forward. Yet human experience is sharply...
Space Time Livestream: Ask Matt Anything
A live Q&A with PBS Space Time turns physics questions into a tour of how “laws of nature” might be understood—through relativity, quantum...
Dissolving an Event Horizon
Black holes may be able to “lose” their event horizons, potentially exposing the kind of singularity that would break causality and destabilize...
Can You Observe a Typical Universe?
The core takeaway is that the anthropic principle can be both powerful and misleading: used carefully, it helps explain why we observe a universe...
Will The Big Bang Happen AGAIN (and Again)?
Cyclic cosmology is getting a serious makeover: instead of a universe that bounces but still needs a “first” moment, a modern ekpyrotic model aims to...
How Black Holes Spin Space Time
Rotating black holes don’t just spin—they drag spacetime itself into a whirlpool, creating a special region outside the event horizon where energy...
Is There Evidence For a Vast Multiverse?
A tiny, positive cosmological constant—responsible for the universe’s accelerating expansion—looks wildly “fine-tuned” compared with what quantum...
A Big Change Is Happening in Physics
Physics is entering a post-speculation phase: once-dominant ideas like supersymmetry, string theory, multiverses, and invented new particles and...
Horizon Radiation
A horizon in spacetime—whether the event horizon of a black hole, the cosmological horizon, or the effective horizon created by acceleration—forces...
The Movement That Could End Capitalism
Bryan Johnson’s “Don’t Die” movement reframes aging and success around a single, measurable mission: slow or reverse the entropy-like deterioration...
String Theory is “Fashion,” Penrose Said. We Finally Have a Response
String theory’s extra dimensions face a renewed, concrete challenge from Roger Penrose—now met with a detailed technical response from string...
Plot Twist! Quantum Physics Prevents Free Will, Physicists Show
A new argument links quantum physics to a hard limit on “agency,” claiming that if the brain and its environment operate purely under quantum rules,...
2022 Year End AMA
The core throughline of PBS Space Time’s 2022 year-end AMA is that “time” and “reality” look different depending on how information is...
