Interesting and/or cool stuff I've come across from art, design, technology, photography, movies I've watched and liked and, occasionally, my thoughts.


There can be too much light.

Today I learned: a Kugelblitz is the (theoretical) phenomenon where the concentration of light (or heat, or radiation) is so intense that it warps spacetime enough to spawn a black hole.

Further down the same Wikipedia rabbit hole I learned of the concept of black hole starships — using black holes as an energy source for interstellar travel.
