Something Strange Happens When You Follow Einstein's Math
Following Einstein’s general relativity leads to a counterintuitive picture of black holes: from the outside, nothing ever truly crosses the event...
What's The Brightest Thing In the Universe?
The brightest sustained objects in the universe aren’t stars or even the brief flash of a gamma-ray burst—they’re quasars, powered by black holes...
Have They Seen Us? | Space Time | PBS Digital Studios
Earth’s century-long radio transmissions have expanded into a light-speed “bubble” that now reaches thousands of star systems, raising a sharp...
Do Black Holes Create New Universes?
Cosmological natural selection proposes that black holes don’t just end stars—they help “reproduce” universes. In this framework, each black hole...
Weird Things Begin to Happen When You Go into Deep Space
Deep space fear isn’t just about emptiness—it’s about learning that the universe’s most “known” facts can be as terrifying as its unknowns. The...
How Does Gravity Escape A Black Hole?
A black hole’s gravity can influence the outside universe without any “signal” escaping the event horizon, because gravity is tied to what happened...
The Boundary Between Black Holes & Neutron Stars
A gravitational-wave merger detected in 2019 appears to involve a “small” black hole candidate paired with a companion mass of 2.6 times the Sun—an...
Are Black Holes Actually Fuzzballs?
Black holes may be “fuzzballs” rather than empty, hairless regions—an idea from string theory that aims to resolve both the singularity problem and...
How Black Holes Kill Galaxies
Supermassive black holes appear to be the main mechanism that shuts down star formation in the biggest galaxies—turning them “red and dead”—and the...
What If Black Holes ARE Dark Energy?
A provocative new line of research claims black holes may be made of dark energy—and that this could help explain why the universe’s expansion is...
10 Physics Myths You Probably Believe!
Popular science often turns physics into a set of spooky, misleading slogans. The central takeaway here is that many “myths” persist because they mix...
Is the Moon in Majora’s Mask a Black Hole?
“Majora’s Mask” moon isn’t a moon at all—it’s a super-dense rocky shell wrapped around a miniature black hole. The claim hinges on a physics mistake...
This correction of Einstein’s theory fixes black holes
A widely circulated claim that physicists have “corrected Einstein’s theory” to remove black hole singularities hinges on a technical move: adding an...
This Physicist Says Black Holes are Quantum Computers
Black holes may function as quantum computers because the physics that governs them blends short-distance quantum behavior with long-distance...
Crazy: Riemann Hypothesis Linked to Black Holes, Physicists Find
The Riemann Hypothesis—an unsolved problem about the zeros of a complex function tied to prime numbers—has become a surprising target for physicists...
Black Holes Could Explain Dark Energy
Dark energy may be explainable by black holes—specifically a scenario where black holes “feel” the universe’s expansion, causing their masses to grow...
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...
