Choose a unit distance in cm that would easily fit on a piece of paper. Let this be your scale distance, now divide your scale distance by 4.3 light years to get the scale that will allow you to convert between real distances and distances in your model. Scale = cm / 4.3 ly = cm / ly
If you were traveling inside a spaceship at a speed of c/2 relative to Earth and you fired a laser beam in the direction of the spaceship’s motion, the light from the laser would travel at a speed of 2c relative to Earth.

How fast does galaxy C recede from galaxy A? Express your answer as a fraction of the speed of light. b.) Processes at the center of a nearby galaxy cause the emission of electromagnetic radiation at a frequency of 2.71×10^13 Hz. Detectors on Earth measure the frequency of this radiation as 1.69×10^13 Hz.
