"We humans have long been obsessed with four great questions: the nature of matter, the origin of the universe, the nature of life and the workings of mind," which was pointed out by Herbert A. Simon (Nobel Laureate in Economics). Accelerators have been and will be a powerful tool to challenge for answers to the above questions except for the working of mind. In order to open up a new horizon of these sciences, the essential is to innovate in key accelerator technologies. Among other things, the innovation of four beam parameters of Energy, Power, size (Space) and timing (Time) with thousand-fold improvement is not an evolution, but a kind of revolution to both scientific researches and technological applications. It is not useless to outline the scientific and technological worlds given by advanced accelerators with the beam structure of 1000 TeV (Energy), 100 MW (Power), 100 pico-meter (Space) or 1 femto-second (Time). My presentation invites you to these worlds. Human beings are full of curiosity and obsess to understand unknowns for many millennia.
