History of the Big Bang Theory Essay -- Historical Science

The strength of the Big jazz theory lies in the evidence for it, non the mechanism used to explain it. Actu ally, the theory has been revise a great deal since its set-back proposition and is probably not exactly as you think it is. Ill explain it in the order of historical development. My apologies if this is a bit technical - dont worry if you dont understand it all.The theory was first proposed in the 1930s, based on Edwin Hubbles discovery that aloof galaxies are receding. Hubble mensural the distances to a large number of galaxies (based on the observed brightness of certain(p) stars within them), and compared these distances with their electromagnetic spectra. As it turned out, more distant galaxies had the features in their spectra ( ghostlike lines) shifted to lower frequencies in a linear manner that is, more distant galaxies exhibit greater redshifts. The only known mechanism for gen durationting a spectral shift is the Doppler effect, which means that distant galaxi es are receding from us.This suggests that in the past, galaxies were a lot closer to us than they are now simply extrapolate the execution into the past. As it turns out, if this is performed, it indicates that all galaxies in the observable universe would have been at the same location about 11 billion years ago that is, all the matter in the universe originated from a single location. This is the (simplified) Big Bang theory. Actually, its a little more complicated than that according to general relativity, its not really that distant galaxies are flying away from us, its that space itself is expanding, increase the distance. You flush toilet think of the universe as the surface of a heave, with the balloon constantly expanding.Not everyone believed ... ...e realm of current science. We dont yet have a theory that can handle the conditions present at that time yet. However, from the era of inflation on, high-energy physicists and cosmologists are quite confident of the theor y, as wild as it sounds In fact, this specific theory makes its own predictions regarding the exact dissemination of fluctuations of the cosmic microwave background, which have so far been confirmed, though realised confirmation will have to wait until the MAP and FERMI satellites catch operational later in this decade.The bottom line is that historical sciences (in this case, cosmology) can make testable predictions the existence of background radiation and its properties, the distribution of light isotopes, the forepart of galaxy evolution, the age constraint, and so on. The same goes with evolutionary biology, another historical science.
