In the summer 2004 I read an article in New scientist discussing if lightspeed has changed during the last few billion of years. (I have also read some Creationist stuff about light being much faster about 6000 years ago, explaining why we can see stars billions of lightyears away in spite of the mere 6000 years since creation:yuck: ) My question is: Would not a change of the speed of light (or rather; the speed that not light or gravity or any other fenomena can exceed), change the speed of all chemical reactions also? Would it not change every aspect of the universe? And would not that universal change "even out" the change of the speed of light so that we will never be able to notice it? If the increased speed of light eg. also makes clocks tick faster (or makes the space expand a bit?), then we may still measure the speed of light to be 299 792 548 m/a. In other words, do we not chase our on tail here?
