By gauging the redshift and apparent brightness of a large number of supernovae located at a variety of distances, researchers can create a record of the universe's expansion. 藉由调校大量位于不同距离的超新星红移和表观亮度，研究人员可造出一组宇宙膨胀的记录。
All the cubes have the same brightness now, but I would like to have a falloff in brightness. 现在所有的立方体有相同的亮度，但是我想要有一个在亮度中减少。
