The laws of physics definitely do change!
I can prove from data that I have collected and stored with high precision GPS receivers over the last 24 years that the velocity of light used to compute the GPS ephemeris has changed several times during that period. Light is slowing down.
Sorry, the laws have not changed, it is our comprehension of their particulars which must change.
And yet, the God deniers claim it doesn’t.
I was pointing out the irony.
The speed of light is not a law of physics, it is a constant (or treated as one). It doesn’t actually contradict the laws of physics to have a changing speed of light. As long as there is a set speed as an upper boundary at any particular time, the laws work fine. Some of your results may change plugging in a different constant into the formulas, but the formulas will still work fine.
compared to WHAT?
