Ok, I'm back.
First, let me say that laws of physics probably don't change overnight, but how do we know that they don't change slowly over time--thereby causing calculations into the distant past to arrive at erroneous results?" For example, some have speculated that the age of the universe has been miscalculated due to a change in the velocity of light. And others have speculated that radiometric data may give flawed results due to decay rates of radioisotopes changing over time. There are a number of reasons for rejecting these hypotheses. As far as the theory about the speed of light changing over time, even the YEC organization, Answers In Genesis agrees that a change in the speed of light is sufficiently huge to result in the universe appearing billions of years while only being thousands of years old is farfetched to say the least. Also, accurate speed of light measurements have been available for long enough to determine that if it were changing over time to any significant degree, it would have been detected. Likewise for radioactive decay--accurate measurements have been available for long enough to determine any significant changes. What do you guys think?
