    Mass is a necessary and useful concept for other reasons. An absolute frame of reference is neither needed nor useful.

    James R,

    Just because something may not be needed or useful, doesn't mean that it doesn't exist.

    Hi Tom,

    "Just because something may not be needed or useful, doesn't mean that it doesn't exist."

    True. But if you can't touch it, smell it, handle it, it is not needed and not useful, then there is a good reason to just disregard the idea as one of those wierd things you came up with when smoking too much pot (that's the answer to most of my ideas anyway

    Bye!

    """True. But if you can't touch it, smell it, handle it, it is not needed and not useful"""

    --> dark matter
    --> dartk energy

    some leading scientists are on the pot, I knew it all the way


    """You're still confused about reference frames."""

    obviously, the only thing you seem to come up with is to say that I am confused and repeat the thing all over

    """Given a reference frame, any object then has a particular speed. Change the reference frame and, usually, the speed of an object changes. """

    okidoki

    """The funny thing about light is that its speed is the same in all reference frames."""

    yes, very funny
    what's even more funny is that because of this we could use it as an abs FOR
    somehow, you seem to completely miss the point here
    say clearly why we can't use light as abs FOR for everything that moves ... why oh why thou Lord?

    That would be for physicians specialised into devices and experiments to find out.

    This one says it can't be done. Relativists 1, Absolutists 0.

    Funny

    Hi c'est moi,

    Short summary of the previous posts:

    c'est moi: yes, very funny ; what's even more funny is that because of this we could use it as an abs FOR. somehow, you seem to completely miss the point here say clearly why we can't use light as abs FOR for everything that moves ...

    James R: Somehow? How?

    c'est moi: That would be for physicians specialised into devices and experiments to find out.

    So at first you say that there is an absolute frame of reference that you can't specify. Then you ask the same physicists to find it, even when they all agree that there is no absolute frame of reference.

    Hrmmmm ?

    Bye!
