    to me it seems that the earth as a planet is moving too fast.Faster than we amagine.
    look
    it moves around on its own axis
    then around th sun
    then the sun is moving with in our galaxy
    then the galaxy is moving around a central point of the universe which we do not know at this time

    if we start calculating all these speeds.
    Imagine how fast we are moving

    There is no central point of the universe. Besides, there is also no fundamental reference frame to which we can relate all velocities. That's the essence of relativity. Velocities only make sense relative to something. And being able to imagine a certain phenomenon is irrelevant, because the laws of nature also apply, if there is none there to imagine them.

    Bad statement. There may be a central point to the universe, we don't know yet so we cant say that there isn't.

    Besides, there is also no fundamental reference frame to which we can relate all velocities.
    Bad statement. There is a fundamental frame of reference, the almighty Ether. However, you are correct that velocities cannot be related to it, due to relativistic effects.[/quote]

    Good statement.
