THE first quarter of the twenty-first century is showing many similarities with its immediately preceding counterpart (the twentieth century), especially regarding science in general, and elementary particle physics, and cosmology in particular; and regarding the latter, the literally earth-shaking discovery made by Edwin Hubble. His observations using earth-based telescope(s), of the “red shift” of light reaching us from the distant stars, showed that the universe is expanding! This has been confirmed and further examined, by probes sent into space as well as ground-based observations.
