Light years,

Theories and

Characteristics

of the Universe


Light year is:

Distance that light travel in a vacuum in one year, about 9.5 trillion km- which is used to record distances between stars and galaxies


Lightyearis:


Light year is not:

Light year is a measure of DISTANCE – NOT TIME!!!!!!
