"시공간" is a Korean term that translates to "space-time" in English. It refers to the four-dimensional continuum that combines the three dimensions of space with the dimension of time. This concept is fundamental in physics, particularly in the theories of Albert Einstein, which describe how objects move and interact in the universe. In Einstein's theory of relativity, space and time are interconnected, meaning that the position of an object in space can affect its passage through time. This relationship helps explain various phenomena, such as the effects of gravity on time and how objects travel at different speeds. Understanding 시공간 is essential for studying the universe and the laws of physics.
