6. Glossary

This game manual is for Universe version 0.8.

This is a glossary of some terms that you may not be familar with.


A parsec is a unit of distance. It is approximately 3.24 light-years. The parsec is defined as the distance at which the radius of the Earth's orbit subtends an angle of one arc second. 


A light-year is the distance that light travels in one year. Since light travels at 3.00x108 m/sec, a light-year is 9.47x1012 kilometers (or 5.88x1012 miles).
