“Cosmology: Man’s Place in the Universe”
by Professor Virginia Trimble
Human beings come in the middle. We are middle sized, middle aged, and middle weight - halfway (geometrically) between the small-scale phenomena of nuclear and atomic physics and the large scale ones of astronomy and cosmology. This means that we can hope to learn about both the atom and the universe by looking at how we came to be here. Life on earth is part of the present epoch of a long history, beginning with (indeed, very possibly before) the Big Bang, the early, hot, dense stage of which we see several relics. Then came the emergence of structures: first, probably, very massive stars, and rather wimpish (in several senses) galaxies; then stars more like our own and larger galaxies and clusters; and planets, life and (arguably) intelligence. Changing even one of the fundamental constants of physics or cosmology would prevent one or more of these vital stages from happening. Thus the very fact that we are here to observe the universe and ask questions about it guarantees that the universe must be more or less the way it is. The implications of this will be explored. |
