The duration of the life-cycle of the cosmos is unknown. Michiel van Overbeek estimates it to be about 150 billion years. The cosmochronos is a clock which displays the time (with an accuracy of half a second) in a unique pattern of 64 lighted and dark surfaces. The cosmochromos has a cycle of about 150 billion years. Thus, the pattern shown at the moment, cannot be seen again for the next 150 billion years.
