    For now. :D

    I'm patiently waiting for a day when c is changed from a constant to a function. ;)

    Here is the problem with the so-called "constant" c. If you go back and look at old physics reference books and college textbooks before c was pegged it was found that c did change by a few percentage points every time it was measured. Not huge changes, but more than could be accounted for by experimental error. The biochemist Rupert Sheldrake points this out in several of his lectures, and others have as well...

    "On October 20, 1983 the meter was redefined again. The definition states that the meter is the length of the path traveled by light in vacuum during a time interval of 1/299,792,458 of a second. The speed of light is

    c = 299,792,458 m/s

    The second is determined to an uncertainty, U = 1 part in 1014 by the Cesium clock. The General Conference made the iodine stabilized Helium-Neon laser a recommended radiation for realizing the meter at this time. The wavelength of this laser is

    λHeNe = 632.99139822 nm

    with an estimated relative standard uncertainty (U) of ± 2.5 x 10−11."

    That's great... define C based on the Cesium clock's "seconds", then define the length of a meter in terms of the Cesium atom, and Viola! The speed of light stops changing because now you have a circularly defined constant.

    The fact is, we really don't know, and modern science does not seem interested in checking if these constants do change... I suspect that they do, but very very slowly.

    To have been "declined, " does that mean you were once "clined?:confused:"
    Yes, charts and maps DO need to be updated periodically. I doubt my TOPO maps bought 20-30 years ago are anywhere near accurate in regards to current magnetic headings. (But that can be fixed easily; the maps are still accurate and serviceable.)

    Or, is "C" a variable constant?:confused:

    We may have to redefine "vacuum." :)

    I thought that Maxwell was too busy playing with silver hammers to worry about equations...
    Speaking of which, Why does I always equal a minus one in "Higher Math"?

    Just alter the declination value on the compass and you're good to go. Right?

    Sometimes it means "Hell No"
    Just ask Paul Thorn.

    And it will not be an over-night event either.

    3. Q: How fast are you going when you past the end of the flat earth? A: Flat out.
    4. Q: How many fake news journalists does it take for full coverage of the flat earth? A: 100 if you slice them thin enough.
    5. Q: Why do flat earthers wear Depends? A: So they don't crap their pants when they get near the edge.

    8. Q: Why did the chicken cross the flat earth? A: To fall off the other side
    9. Q: If we all live on the top side of the flat earth, who lives on the other side? A: Bats and Count Dracula
    10. Q: Who was the first flat earth man in space? A: A lying husband who just kept digging his hole deeper and deeper.
    11. Q: How did the flat earth husband die? His fat wife fell flat on his face.

    13. Q: What kind of cats make the best flat earth pets? A: Road kill cats.
    14. Q: How do men score by explaining the flat earth to women? A: Flattery will get you everywhere.
    15. Q: Why do flat earth referees never flip a coin? You can't flip a coin with heads on one side and nothing on the other.
    16. Q: What is the flat earther's favorite breakfast? A fried egg, a pancake, flat steak, and an onion ring.
    17. Q: How did the flat earther get lost? He went into a round about and couldn't think his way out.
