outer
Outer refers to the exterior or outermost part of something, often emphasizing what's on the surface or boundary rather than the core. In everyday and scientific contexts, it highlights separation from an inner or central element, like the outer edges of a galaxy or the outer layers of the Earth's atmosphere, adding a sense of exploration and vastness to modern discussions about space and design.
Did you know?
Did you know that the concept of 'outer space' is officially defined by the Kármán line, about 100 kilometers above Earth, where the atmosphere is so thin that a vehicle must travel faster than orbital velocity to stay aloft? This boundary, named after Hungarian-American engineer Theodore von Kármán in the 1950s, marks the start of space and has influenced international space law, including treaties that govern human activities beyond it.
