It seems like everything is built from matter-galaxies, stars, planets, houses, cars and even us, programmers. The Universe would be dead without it. Energy is the source of change, movement, life. We need space into which to put matter, and we need time to see matter change.
Programming is like creating universes.
Objects would be dead without code that operates on them. Objects need space to be put into and to relate to each other. Lines of code need time to be executed. The space-time of the program is described by scopes. An object lives and dies by its scope.
