R=sc2
Respect equals sass times the square of the speed of light.
--- End quote ---
That would be the special case Respect equation.
The general Respectability equation would be
R2 = (sc2)2 + (pc)2
where pc is political correctness though some theoreticians insist that p is the inertia of the body being observed relative to the observer and c is the speed of light as a universal constant
- I personally do not have much faith in that since it has been proven that the speed of light is not a universal constant and is affected by what it travels through or by.

(click to show/hide)No, that should be a strawberry "e" Clair but a chocolate fondue. (click to show/hide)

When physicists refer to the speed of light as a universal constant, they're referring to the speed of light in a vacuum. The speed of light in media is a whole other can of worms, but the speed of light in vacuum is constant.*
*To the best of our measuring capabilities. There are experiments trying to measure changes in the fine structure constant which would indicate changes in the speed of light in vacuum, but no significant changes have yet been observed.
Thrudd:
Yeah but part of the problem in doing any of those measurement is that we are sitting in a gravity well that is inside another gravity well etc etc etc all while being bombarded by an erratic stream of random high energy particles.
Its like doing precise drafting while sitting in a canoe going down the Colorado river in springtime.
There are enough inconsistencies in observed distant interstellar phenomena that some are pretty sure something isnt right about the assumptions.
The challenge is determining what the actual [censored] is going on and determining what does have a direct effect on the observed phenomena.
Theories and established assumptions do not die out until their establishment proponents die off.
That is something that has not changed and will not change until the nature of HomoSapiensSapiens changes.
cesium133:
The physicists who do high-precision measurements are pretty good at accounting for those sorts of things. I'm not saying it's absolutely true that the speed of light (in vacuum) is constant, but to the best precision it's been measured (and some very high-precision measurements have been done), it hasn't been observed to change.
Thrudd:
On the surface that uncertaintity value seems quite small but the moment you toss in celestial distances the numbers go all weird.
They also use an assumption [pretty solid by what we know for now] with an inference for a deduction.
I remember one example my prof in first year used to demonstrate how tiny changes can have significant effects.
1 km piece of continuous rail expanded as it warmed up.
If one end is fixed and the other allowed to move upwards within the 1 km space, how high would it move when the temperature changed from 25'C to 35'C ?
Good ole Pythagoras Theorem - Math is Fun. :-D
