Except for the results of a very basic physical formula that we all know: E=MC^2. If the speed of light (C) were higher in the past, the energy (E) or mass (M) of distant stars would be likewise effected, and we could clearly see that they were operating under different physics. They aren't.
For that matter, if C were high enough 6000 years ago to bring us the light of stars billions--or even millions--of light-years away, Adam would have been instantly incinerated by the vastly increased light of the Sun.
Even Danny Faulkner, being a Young-Universe Creationist but also an astronomer, admits that speed of light decay is a non-starter for defending the position.
Food for thought. Shalom.
I’m sure the earth is significantly older than 6K years old. I’m not even debating the big bang component of creation. But I would argue that E=MC^2 because speed is regarded as constant.
If you allow for the possibility that the laws of physics are evolving with the universe, then what we understand about the universe today may confuse our theories about how our universe started 13 billion years ago. Steven Hawking is confounded about how a infinate amount of mass stored an infanite amount of energy in an infanitely tiny space at some (yet undiscovered) quantum level of existence. If as you point out, the nature of energy itself has also changed with the “C”, then more energy starts to fit in less mass and less space. Does it not? Run the calcs. Then drop Hawking a note.
At Planck time there is no way the command “Light Be’ can manifest. If one calculates far enough ‘down’ they reach a point/moment when time is space and space is time, kind of like walking to the North pole and then keep walking and you will be headed toward the south pole. Therefore a period of inflation (the differentiating of dimension space and dimension time) created the spacetime where radiation can happen and underlies everything (the zero point field). Then The Creator spoke matter and thus worlds into existence.
“If the speed of light (C) were higher in the past, the energy (E) or mass (M) of distant stars would be likewise effected, and we could clearly see that they were operating under different physics. They aren’t. “
Or are they? We assume that the doppler shift is due to motion, based on our understanding of light. What if it isn’t? What if the energy from those stars is different due to the changing speed of light?
