Quantum Gravity and the Hardest Problem in Physics | Space Time
The hardest problem in physics isn’t just that general relativity and quantum mechanics disagree—it’s that the usual way quantum theory is built...
Why String Theory is Right
String theory’s biggest draw is that its mathematics naturally produces gravity—and does so without the infinities that typically wreck quantum...
How Will the Universe End? | Space Time
Far-future physics points to a long, mostly dark endgame: the universe will spend nearly all of its infinite lifetime cooling toward maximum entropy,...
How to Detect Extra Dimensions
Gravitational-wave observations from the 2017 neutron-star merger GW170817 have been used to place a sharp limit on extra spatial dimensions: the...
Hawking Radiation
Black holes aren’t perfectly black: quantum effects in curved spacetime make them emit radiation and slowly evaporate. That insight, first formalized...
First Detection of Life
The most consequential idea in this account is that “life detection” from afar should rely less on finding familiar molecules and more on spotting...
What Survives Inside A Black Hole?
Black holes may look like perfect information traps, but the outside universe still “remembers” three specific properties: mass, electric charge, and...
The Black Hole Information Paradox
Black holes don’t just swallow matter—they may also erase the quantum information that, by the rules of quantum mechanics, should be preserved...
The End of the Habitable Zone
The Sun’s steady brightening will push Earth out of the habitable “Goldilocks zone” long before humans reach the end of their species—triggering a...
Time Crystals!
Time crystals—materials whose internal dynamics repeat at a fixed rhythm even when driven by an external periodic signal—have moved from a...
Neutron Stars Collide in New LIGO Signal?
A fast-moving rumor tied to a specific gamma-ray burst and a nearby galaxy claims LIGO has detected gravitational waves from a neutron star–neutron...
How Asteroid Mining Will Save Earth
Asteroid mining is being pitched as a practical next step for extracting high-value materials—especially platinum-group metals and industrial...
Will A New Neutrino Change The Standard Model?
A growing set of neutrino measurements points to a possible “sterile neutrino”—a new kind of neutrino that would not interact through the weak...
