About these units

Millimeter/Hour (mm/h)

A millimeter per hour is extraordinarily slow, used in geology, meteorology, and materials science to measure phenomena like soil creep, tectonic plate micro-motion, or extremely light precipitation (drizzle). In manufacturing, mm/h may describe slow deposition rates in thin-film fabrication or high-precision milling processes. Despite seeming negligible, speeds measured in mm/h can accumulate into significant changes over weeks, months, or years—making them essential for long-term studies.

Cosmic Velocity - Third (v₃)

The third cosmic velocity is the speed required to escape the entire Solar System from Earth's orbit, overcoming the gravitational pull of the Sun. This speed is approximately 16.7 km/s, though missions often achieve this gradually using gravitational assists rather than brute-force acceleration. Space probes such as Voyager 1, Voyager 2, and New Horizons have exceeded v₃, making them interstellar travelers. The third cosmic velocity represents the threshold where an object ceases to be bound to the Sun and begins drifting through the galaxy—one of the most profound expansions of human technological capability.
