Ask PrometheusWhen two things are at the same place in space during time and their boundaries touch.
Contact (noun) means: When two things are at the same place in space during time and their boundaries touch. It emerges from space, time, boundary, others: Two distinct entities with boundaries occupy the same region in space and time, causing their boundaries to touch, enabling mutual influence. In the EmergenceLexicon it sits at computed level 4, chaining down to the four foundations (space, time, energy, pattern).
Examples
- The International Space Station's solar arrays physically contact debris at orbital speeds, causing micrometeorite pits visible on returned panels. engineering
- Two billiard balls touch momentarily after a break shot on a pool table at the 2023 World Nine-ball Championship. everyday life
- Neurons in a mouse hippocampus physically contact each other at synapses, verified via electron microscopy in a 2017 Max Planck study. biology
