The idea that the acceleration that we feel from gravity is due to the earth expanding is pretty crazy in my opinion. I suppose the reason we do not run into the moon is because while the moon is also expanding the space between the moon and the earth is expanding at the exact rate that appears to keep our distance constant, like I said pretty crazy. What is expanding? the distance between atoms? The distance between the nucleus and electrons in an atom? Are there just more atoms forming? Are the fundamental particles themselves expanding?
If the expanding earth is what gravity really is, why do satellites stay in orbit, an expanding earth will not affect something in orbit, right?
