Address

“What is our address in the universe?” This was a popular topic discussed on the Internet recently. The question has resulted in many interesting answers, which also indirectly showed people’s wide array of imagination towards the universe. When we refer to our familiar everyday experiences to try to grasp a particular circumstance, a wrangling between the unfamiliar and the familiar then ensues. The correct answer to the Earth’s cosmic address is said to be: “Universe-Laniakea Supercluster-Virgo Supercluster-Local Group-Milky Way Galaxy-Orion Arm-the Solar System-The Third Planet—Earth.” Each of the scientific terms listed is based on an allusion, but what really resonates with us, no matter how miniscule the resonance may be, is likely due to some correlating daily experiences that have guided our hearts to a cognitive process that’s far far away.

The Correct Gauge

The title of the exhibition, The Weight of Multiple Universes, alludes to questions on such experiences of perceptual knowledge. The concept of the “universe” entails spatial and temporal factors. It encompasses everything that’s in the celestial skies, things that are unknown and difficult to gauge. Weights and measures refer to the fundamental physical quantities of length, mass, and weight. In order to develop statistics based on this foundation, the correct gauge, an instrument that measures these units, then becomes quite crucial. In astronomy, light-year is a common unit. It may be difficult for us to imagine just how far 9.46 trillion kilometers (9.46×10 ¹ ² km) is, which is the distance that light travels in a vacuum in one year. The concept is still hard to comprehend even if we use the length of Taiwan, which is 394 km, as a gauging reference point. However, it becomes easier for us to visualize when a different method of measuring is used, for instance: “It takes light an average of around 8 minutes to travel from the Sun to the Earth.” Therefore, the Sun we see on Earth was emitted from the actual Sun 8 minutes ago, and we see the Moon not as it is but as it was about 1 second ago. Based on this, things seem to become easier for us to grasp.
