For The First Time, Scientists Achieve ‘Liquid Light’ at Room Temperature

Circa 2018


In June 2017, physicists achieved ‘liquid light’ at room temperature for the first time ever, making this strange form of matter more accessible than ever.

This matter is both a superfluid, which has zero friction and viscosity, and a kind of Bose-Einstein condensate — sometimes described as the fifth state of matter — and it allows light to actually flow around objects and corners.

Regular light behaves like a wave, and sometimes like a particle, always travelling in a straight line. That’s why your eyes can’t see around corners or objects. But under extreme conditions, light can also act like a liquid, and actually flow around objects.

Opting In for a Positive Future — Allison Duettmann

Excellent speech.


Our civilization is made up of countless individuals and pieces of material technology, which come together to form institutions and interdependent systems of logistics, development and production. These institutions and systems then store the knowledge required for their own renewal and growth.

We pin the hopes of our common human project on this renewal and growth of the whole civilization. Whether this project is going well is a challenging but vital question to answer.

History shows us we are not safe from institutional collapse. Advances in technology mitigate some aspects, but produce their own risks. Agile institutions that make use of both social and technical knowledge not only mitigate such risks, but promise unprecedented human flourishing.

Watch this video where we investigate this landscape, evaluate our odds, and try to plot a better course.
