Is time in the microcosmic world faster than time in the macrocosmic world?
Time is motion. The motion of matter in various parts of the universe varies from imperceptibly slow to imperceptibly fast. I don’t know of any reason for the fastest and slowest motions to be fundamentally different within the microcosmic and macrocosmic domains. It is true that many high-speed particles in “empty” space cannot be observed until they have been slowed by collision with still other matter. They are like bullets, which we may not observe enroute, but may be all too real on impact. An infinite universe will always have tinier and tinier particles feeding what we experience as reality. These particles don’t necessarily have to be traveling fast–they might just be too tiny for us to detect.
