Magna Ignotum

The Magna Ignotum (Latin for Great Unknown) was a large, unexplored sector of space. Even though the ability to travel 200,000 times the speed of light (not 1,000,000 times like the transwarp drive) had existed for fifteen years since the creation of the Magna Ignotum no Federation, Cardassian, Talaxian, or whatever scientist had journeyed near or into the space, even after the transwarp drive was created. A number of reasons were given over the years as to why, all of which will be listed shortly.

Dimensions
Even though taking up about one-hundredth of the galaxy, the Magna Ignotum was very extensive, nearly a twentieth of a quadrant in size. More precisely, the Magna Ignotum was about five-thousand light-years across in width. Based off of this size estimate, the Magna Ignotum was claimed to contain 500,000 sectors, 3,500,000 planets, and about 700,000 potentially habitable worlds.

The Magna Ignotum was around 25,000,000 square-light-years in area, which translates into 2.333 square kilometers.
