    It looks like 'amber' is just a banned member returning to do a little trolling.

    t/dx of c would be 1 year, I do not see where there is any difference in saying it this way.

    X would be a vector length.

    light year
    noun
    1. ASTRONOMY
      a unit of astronomical distance equivalent to the distance that light travels in one year, which is 9.4607 × 1012 km (nearly 6 million million miles).
      • informal
        a long distance or great amount.
        "the new range puts them light years ahead ofthe competition"
    It's a distance. I know it's a distance but I was baiting Asexperia who put forward the weird idea

    Speed of light is 299 792 458 metres per second

    Seconds in a year (Earth) 31557600 approx

    Multiply 299 792 458 X 31557600
    you get that 1 light year is approx

    9,46,07,30,47,25,80,800 or
    9.461x10^15 metres approx or
    9.5 trillion kilometres approx

    What does t/dx of c mean?
    What is a vector length?

    t is time
    d is distance
    x is the vector

    x is a vector that has a length or a distance if you like. A start point and an end point. I am surprised you do not know what a vector is. c is the speed of light approx 300,000,000 m/s , this is known as a light second.

    Yeah, the distance light travels in ONE SECOND. Wake up.

    I do know what a vector is, a vector is an object that has length and direction, I have no idea what you think a vector is.

    Unfortunately, what you have presented is gibberish...

    The speed of light is a light second?
    Complete nonsense.

    You seem to be saying that time divided by a distance divided by a distance (of some vector) of c?
    That is complete nonsense.

    Based on your past posting very soon you will proclaim that you are a sock puppet (imagine my surprise) and will run away (again).

    It is funny how you come back here every so often to remind us you are still have no idea what you are talking about. We do not need to be reminded we already know....

    but she is technically correct that the speed at which light travels is a velocity.

    The speed of light is indeed a velocity. But a light year is a distance not a velocity.

    The distance to Alpha Centauri is ~4 light years. Amber is claiming a distance is a velocity. That is like saying the distance to Toledo is 45 mph.

    I think you must be reading something completely different to that which I am writing.

    A light year is based on velocity, the distance is set by the velocity . The constant distance of 1ly is because the speed of light is constant. A light year is a distance but it is also a velocity . If you do not travel at c it will take a lot more time than a 1ly to get there.

    Us women are always correct, it is only men with such big egos who do not admit to being wrong.

    So in your confused world something can be both a distance and a velocity?

    The world must seem like such a mystery to you.

    1ly is a distance defined by the velocity of light, in our world that is how things are.

    Of course it is. It is refreshing to see that you have finally understood.

    I always understood, it seemed you that was a bit confused.

    A light year is a distance, not a time. However, if you're going 5,000 light years PER HOUR then you have a speed. You just quit before you were finished.

    And I asked what use is a unit that is not constant?

    The gazelle apparently runs slightly faster today than yesterday, because today is slightly shorter.

    Never understood this rationalization.

    If time is what clocks measure, what was it before clocks were invented? That was, after all, 99.999997% of the universe's life.

    False.

    The Solar system has travelled a light year around the galaxy's centre, and it has taken considerably longer than a year to do it. Because (plainly) it is not moving at the speed of light.

    ie. a light year is a fixed distance no matter how fast or slow you traverse it.


    This isn't really a debate. A light year is a unit of distance. It is not a unit of time. Full stop.
