The lecture was based on galaxies. The speaker explained that NASA captured the picture of galaxies by Hubble’s space telescope. This picture shows many clusters held together by gravity. However, the gaps between galaxies are not dark between the expansion if the universe cause lights to be shifted to lower frequencies. To conclude, this picture was taken by three different telescopes but it looks very awesome with different perceptions.
