Nor a physicist.
"but I fail to see what GPS has to do with light speed”
Do you know how GPS works?
Imagine if there were three people on a REEEEEEEEEEEEEEEEEEEEEEEEEEEEALLY big football field, and each one shouted, ‘This is the 8 o’clock pulse!’ at 0800.0000.
You have a precise enough clock to know that you heard one of them at 0800.001 and two of them at 0800.003.
So you know that you’re .003 light seconds from two of the shouters, and only .001 light seconds from the third one. There’s only one spot in the football field that matches those numbers.
And that’s with all four of you in the same gravity field, at the same depth.
Further imagine that they’re so very high up that time actually runs faster where they are. So at the moment they say ‘this is the 8 o’clock pulse’ your hyper accurate clock tells you that it’s 0759.9993.
You need to take that difference into account to know how long it took you to HEAR the 0800 pulse.
If you don’t, then you’ll never get an accurate measurement of your location.
“and time slowing down.”
Because this IS the real world, and the system doesn’t fucking WORK without knowing how physics affects you.
Same way we know that the Earth rotates because if you’re shooting a Howitzer at a target far enough away, and you don’t take Earth’s rotation into account, you miss.

Dude, either have the moral integrity to not swear, or fucking use the words you want. Don’t pretend to swear while pretending to be moral about it. You look stupid.
“ asking where I've been for the past 100 years. Goodbye.”
Dude, you’re the one rejecting the most current science.
You don’t admit ignorance without bitching about how other people know this shit. So they’re snippy because you started it.
