      What "real science"? What do you mean? Science is a way of thinking, of always searching for proofs that could contradict our way of thinking. You clearly haven't trained this "scientific" mind of yours because seeing something that challenges your view on reality is unconfortable for you. Maddening, in fact, because it pushed you to write 6 meaningless and sad comments.

    The different rates of clocks at different heights is only half the story for why geodesics near earth's surface accelerate downward. The rate clocks tick depends on your speed as well as your height, and both speed and positional dependence are crucial. See www.feynmanlectures.caltech.edu/II_42.html

    Long story sort. Down is where the time is slower , which means down is where there are big concentrations of mass, which means down is where there is curvature on the fabric of space time.
    If you ask me, there is only one direction. Forwards, but just on another direction relative to a point of reference. I say that bcs if the space and time are one and we can only move forwards in time, then we should be allowed to only move forwards in space too. And I dont really believe that movement should be characterized as forwards backwards up down etc, we just move. We can only characterize movement only if we have a point of reference, and in this case it can only be forwards.
    And the word "forwards" characterizes the only movement that an object is allowed to make and not the direction relative to an object.
    Another way of explaining why down does not exist
    Down is where we say things are relative to a point of reference on ourselves (our senses to be exact). The way our brains processes the environment has made us think of abstract things like up, down, forwards, backwards etc to explain actions that happen and to not lose track of our surroundings. Every direction except forwards in my opinion is not truly real and just a construct of your minds. Forwards is not meant to be used with a point of reference but to explain that a thing just moves to the only direction that is allowed to do.
    Ps. These words (up down, forwards backwards,), where not made to describe these ideas about space, time and many other things, but just to be used in our every day life.

  • dryten

    i think the idea of the differential in the effect of time on the top of an object vs the bottom resulting in the apparent effect of gravity is amazing, but it raises some questions for me
    why don't larger objects (with a bigger difference between the top and the bottom) fall faster?
    why are singular, fundamental particles with no apparent width affected by gravity?
    how does light fit into this picture?
    etc, maybe i missed something idk

    Wait can someone answer this. About the dropping the pencil 6ft thing. If you, before you drop the pencil, measure the distance sooo accurately to the nanometer of the tip of the pencil facing toward the ground and the ground itself, and then you record the pencil dropping and somehow calculate the distance it fell, would the distance it fell be less than the distance you measured beforehand? Because he said the earth is attracted a tiny tiny bit when you drop the pencil.
