Comoving distance and proper distance. Comoving distance is the distance between two points measured along a path defined at the present cosmological time. For objects moving with the Hubble flow, it is deemed to remain constant in time. The comoving distance from an observer to a distant object (e.g. galaxy) can be computed by the following ...
Flight length. In aviation, the flight length or flight distance refers to the distance of a flight. Aircraft do not necessarily follow the great-circle distance, but may opt for a longer route due to weather, traffic, to utilise a jet stream, or to refuel. Commercial flights are often categorized into long-, medium- or short-haul by commercial ...
In New Zealand, a leading Māori navigator and ship builder was Hector Busby, who was also inspired and influenced by Nainoa Thompson and Hokulea's voyage there in 1985. [82] In 2008, an expedition starting in the Philippines sailed two modern Wharram-designed catamarans loosely based on a Polynesian catamaran found in Auckland Museum. The ...
New Zealand ( Māori: Aotearoa) is an island country located in the southwestern Pacific Ocean, near the centre of the water hemisphere. It consists of a large number of islands, estimated around 700, mainly remnants of a larger landmass now beneath the sea. The land masses by size are the South Island (or Te Waipounamu) and the North Island ...
v. t. e. Food miles is the distance food is transported from the time of its making until it reaches the consumer. Food miles are one factor used when testing the environmental impact of food, such as the carbon footprint of the food. [ 1] The concept of food miles originated in the early 1990s in the United Kingdom.
A formal definition for travel time reliability is: the consistency or dependability in travel times, as measured from day-to-day and/or across different times of the day [1]. In addition, there are many different ways to define travel time reliability. For example, according to NZTA, trip time reliability is measured by the unpredictable ...

Proper time. In relativity, proper time (from Latin, meaning own time) along a timelike world line is defined as the time as measured by a clock following that line. The proper time interval between two events on a world line is the change in proper time, which is independent of coordinates, and is a Lorentz scalar. [ 1]
