Both articles are based on something from 6 years ago which everyone in the scientific world has forgotten 6 years ago. The figures:
# In 1738: 303,320 +/- 310 km/second
# In 1861: 300,050 +/- 60 km/second
# In 1877: 299,921 +/- 13 km/second
# In 2004: 299,792 km/second (accepted constant)
The explanation is simple. It was not easy in the past to measure something moving at such unbelievable speeds. As time has passed, we have developed more accurate instruments which have narrowed the margin of error, so eventually arriving at the correct speed. How the speed of light was measured (about halfway down page):

With answersingenesis there are two rules to remember.
1) They can only show the bible right by showing science is wrong, and there is no lie or depth they will not stoop to, to do this.
2) Remember Rule One.
