Physicists have created a quantum version of a famous thought experiment: the so-called Hilbert Hotel, which is always full and yet a vacancy can always be found for additional unexpected guests. Back ...

A mind-bogglingly large hotel has provided inspiration for expanding the data-carrying capacity of light. A new technique that manipulates the twistiness of light is the optical equivalent of a ...

In a thought experiment first proposed in the 1920s, the Hilbert’s Hotel has an infinite number of rooms and helps demonstrate some of the strange properties of infinity. NOVA is available to stream ...
