44. Why do scientists study distant galaxies to learn about early galaxies? • Distant galaxies are just beginning to form, so they are very similar to early galaxies. • Distant galaxies share many characteristics with early galaxies. • Distant galaxies have not changed as much as close galaxies, so they are most similar to early galaxies. • Because it takes a long time for light to travel through space, looking at distant galaxies shows what early galaxies looked like.
