I stumbled across a creationist site today (http://www.wasdarwinright.net/bigbang.htm). Almost all of their objections to the Big Bang have been solved except this: (c) Confusing supernova. Type Ia supernova explode with a known intensity, and therefore their distance should correlate well with the observed red shift. However, some supernovas at great distance have been found to be brighter than expected, and some nearer have been found to be dimmer. The preferred solution is that the cosmological constant, (the repulsive force sometimes called dark energy) was at first weaker than thought when z <1.5, but then kicked in with a vengeance and today the universe is thought to be expanding faster than expected with values of z >1.5. However, this leads to many more anomalies. Other observations suggest that the cosmological constant is either zero or very small, but nowhere near enough to account for the expansion of the universe that the big bang theory requires. Alain Blanchard of the European Space Agency stated that data collected from the European XMM Space satellite ‘leaves little room for dark energy.’ (ESA News release 12 December 2003). What does this mean for the Big Bang?
