    I Gravity: What Moves a Stationary Body?

    Oh well, never mind. It sounds like a stupid question anyhow. What I should have said is can someone lead me through the process. But I'm sure you must be ready to tear your hair our with me so I'll thank you all and let the matter drop.

    Thank you. I appreciate your kindness in the way you answer. And I am getting used to the idea of spacetime after receiving a lot of help from everyone.

    I Gravity: What Moves a Stationary Body?

    I've thought about it now and asked several more questions and every time I've received helpful replies. I want to thank everyone for their help (and forbearance against my stupidity). You have all been great.

    Thank you IBIX. I do know a bit of maths as it happens so now I have a link which I can follow up.

    I Gravity: What Moves a Stationary Body?

    What I now think I know is that as the Earth moves through spacetime it bends spacetime as it travels along. When Earth moves along a bit it leaves the bent piece of spacetime behind and it straightens itself out as the Earth bends a new piece as it were. It's a dynamic process. So in fact my...

    quote: "these transforms could be interpreted as meaning that space and time were part of one 4d structure, christened spacetime." Would anyone care to expand on this a bit, please?

    I Gravity: What Moves a Stationary Body?

    OK I give in. I know you are all right of course. What I also feel is that because people have experienced space and time as separate things since time immemorial it is rather a lot for us to swallow the idea that they are part of spacetime, a thing we had never heard of when I was young. But...

    I Gravity: What Moves a Stationary Body?

    I am now thinking in terms of spacetime and my comments are now:- Let the smaller masses' projections of spacetime geodesics on to space be called space paths for simplicity in my question and its likewise projection of spacetime geodesics on to time and which I will call time pathways for...

    I'll think about it. Thanks for now.

    I Gravity: What Moves a Stationary Body?

    Now that I've thought about your replies it seems to me you haven't really answered my question because although time is a part of spacetime it doesn't curve around a mass like space does, so far as I know. And although the mass moves through time it is presumably not moving along one of the...

    Yes I see. Thank you.

    I get it. Thanks.

    I Gravity: What Moves a Stationary Body?

    We are told gravity is a curvature in spacetime but the force of gravity only seems to apply if the body is moving. What moves it if it starts off stationary and then falls?
