Why is the speed of light considered a constant (never changing)?

Honestly, that's a good question...Maybe because it...is???

Nope, try again

Okay, nobody wants to play.

The speed of light is considered a constant... by definition. Not by empirical evidence, not by repeatable testing, but because some guy said so (seriously, check out Wikipedia).

Why is this a big deal? Because if it isn't a constant then radiometric dating, for example, is useless (that's not when radioactive people smooze, it's how object's age are determined). Anything measurements depending on atomic processes are null and void. Like the age of bones, fossils, rocks, ANYTHING.

That's a lot of science depending on a definition...

Oh Rob, it's not that I don't want to play... it is just soooo beyond my comprehension. :( (As many of your topics are). One of these days there will be a topic I can participate in. :)

That one is way too deep for me. It requires thinking, and on a normal day, I don't do too much of that. But for the last several days...
