In 1987, a supernova was observed in a neighboring galaxy.Scientists believed the galaxy was 1.66 x 10^21 m away. How many years prior to the observation did the supernova explosion actually occur?
The diameter of our disk-shaped galaxy, the Milky Way, is about 1.0×105light-years. The distance to the Andromeda galaxy, which is the spiral galaxynearest to the Milky Way, is about 2.5 million light-years. If a scale modelrepresents the Milky Way and Andromeda galaxies as dinner plates 20 cm indiameter, determine the distance between the centers of the two plates.
