    Default What I Observed

    I just observed a long train passing by, and it seemed that more
    noise and rumble occured at the ends relative to the center.
    Itís just one crappy observation, does it have any physics to back it up?

    Its called the Doppler effect, an object moving toward or away from you is changing pitch where as an object next to you has the same pitch. Another example is the relative speed of light its speed always remains the same but if source of the light is moving away from you its shifts into the red spectrum if the source is moving towards you it shifts into the blue spectrum. And that is how we know the universe is expanding rather then shrinking.
