Purpose of Exhibition

Celestial objects and various information on astronomy subjects are displayed on the perimeter of this exhibition room. Walking clockwise along the wall, we can travel through the scale of the universe starting from the size of the Earth to the edge of the universe.
This scale is based on the notion of "Powers of Ten (10 no Bekijyo, in Japanese)", making the lengths of each step you take 10 times longer then the last one.

Additional Knowledge

[Powers of Ten]
The idea of viewing the world every Power of Ten in the length, was first visualized in 1977, by Charles and Ray Eames, in a short 9-minute film. This film was also published as a book at the same time, which was also translated into Japanese. Now in the 21st century, we know much more about space and the universe compared to the time when the Eames made their film. For example in 2006, we found that the universe was born 13.8 billion years ago. In this exhibition room the universe is presented with the latest information known to science.
When you enter from the north entrance, the scale on the wall starts with 107 meters representing the size of the Earth. This scale is written on the wall around the exhibition room but also on the exhibition table along the wall. On the bottom of the exhibition table, famous objects are displayed at their corresponding distance scale from the Earth, along with their astronomical data and accompanying photographs. Some of these objects are also displayed in the touch screens or round panels, along with additional astronomical information such as the classification of the Unvierse or the way to measure distance in space. The density in which these objects are located in this exhibition indicates the distribution of our current knowledge about the Universe. Reflecting our understanding of the Universe today, dense regions represent the areas in which we have a good understanding, while the less dense regions represent the areas where we lack understanding. This set up also allows us to add a new exhibition when a new discovery is made. This exhibition room is connected from present to both the past and the future.
