space is very cool.
Space is the boundless three dimentional extent
oh yea its so vast
Physical space is often conceived in three linear dimentions
oh really that sounds sciency.
The concept of space is considered to be of fundamental importance to an understanding of the physical universe 
oh really?
Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.
determining their physical conditions, specially because heavier elements provide higher velocity resolution.
Astronomical importance Importance of interstellar OH observations OH masers.
OH masers, a type of astrophysical maser, were the first masers to be discovered in space and have been observed in more environments than any other type of maser.
In the Milky Way, OH masers are found in stellar masers (evolved stars), interstellar masers (regions of massive star formation), or in the interface between supernova remnants and molecular material. Interstellar OH masers are often
