1) Please show me where the speed of light has changed in the last 50 years. I know you’ll cite differences based on available tech at the time prior than 50 years.
2) You never answered my question as to why a Type 1A supernova are pretty much uniform from location to location. Very rarely is anything different between them. Yet the speed of light when they occurred all varied WILDLY. EXPONENTIALLY so even.
3) The pat answer I usually get for the time/distance discrepancy is “gravitational time dilation”. AS if those three words actually answer anything. Since you replied to my post citing that, I tried to follow up with you. Since you don’t want to tackle that, then we’ll skip it.
So why did you change your tune from the last 200 to the last 50 years? You said the measurements had been constant. Now you admit they haven't and have changed the timeline. What's next?
"2) You never answered my question as to why a Type 1A supernova are pretty much uniform from location to location. Very rarely is anything different between them. Yet the speed of light when they occurred all varied WILDLY. EXPONENTIALLY so even."
Because you only define those supernovae that fit the criteria as Type 1A. The others are 'something else'.
"3) The pat answer I usually get for the time/distance discrepancy is “gravitational time dilation”. AS if those three words actually answer anything. Since you replied to my post citing that, I tried to follow up with you. Since you don’t want to tackle that, then we’ll skip it."
One again, it's not my argument and I never referred to it.
You have avoided explaining the 'horizon problem', which I did posit to you.
