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...
What Happens at the Event Horizon? | Space Time | PBS Digital Studios
At the event horizon, black holes don’t just hide information—they reshape what “future” and “escape” even mean. Using Penrose diagrams, the episode...
White Holes | Space Time
White holes are the time-reversed mirror image of black holes: instead of trapping everything behind an event horizon, they eject everything and...
How Time Becomes Space Inside a Black Hole | Space Time
Inside a black hole, the usual roles of space and time don’t just get distorted—they swap in a way that forces a one-way future. Outside the event...
What’s On The Other Side Of A Black Hole?
A black hole’s “point of no return” is often treated like a hard boundary, but the mathematics of spacetime mapping shows it behaves more like a...
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...
Can Black Holes Unify General Relativity & Quantum Mechanics?
Black holes force a direct collision between general relativity and quantum mechanics: the same quantum information seems to be both destroyed and...
Escape The Kugelblitz Challenge
The episode’s core insight is that realistic black-hole formation is messier than the ideal “eternal” black hole often drawn in textbooks: during...
How to See Black Holes + Kugelblitz Challenge Answer
Black holes are no longer just theoretical objects: astronomers can infer their presence and test Einstein’s general relativity by watching how they...
