about speed of light

we know that speed of light is an unconquerable term in physics..light takes about 1 year to travel 9500000000000000 metres that is light year....suppose i have a needle of length 95000000000000000 metres long....suppose that one end of needle is at my hand and other end is at distance 95000000000000000 metres apart. . now if i push gently the end of needle at my hand then at the same time the other end at a distance of 95000000000000000 metres will move forward.....now light has taken 1 year to travel a distance of 95000000000000000 metres..and i have made a mechanical disturbance to travel the same distance with in no time from one end of the needle to other end placed at a distance of 9500000000000000 metres apart. in other words i have made a mechanical disturbance to travel at a speed greater than light

  • Jan 22 2012: Do not forget several issues:
    1. Not all of the relativity theory is true and some was "proven" by wrong experiments.
    2. It assumes that space and time are homogeneous and linear in nature.
    3. Light speed is actually the speed of photons, which are massless. But yet, we can measure the impact (mv) of a light wave on a black/white plate (!?)
    4. Einstein's E=mc^2 is only describing an approximation of how much potential inner kinetic energy is stored in the second level of material's structure (as we know it).

    Etc.
