    I don't , you keep adding the fuel with your ridiculous responses .

    Sure , but so what .

    What about expansion evolves space ?

    Yes you have, and probably more then a couple of times....

    I'm certainly not going back any further just to appease a proven troll.

    So it evolves. Dave already told you that much earlier.

    Just though it worth resurrecting to prove the point I'm trying to make.
    Yes, spacetime certainly bends..and warps and twists as per the evidence I have already shown you in graphical representations and observations.
    And of course bending is a property, as well as being able to expand.

    Yet gravity waves away from the source not inwards , into the source .

    Further , the moon should not have been captured by Earths gravity .

    Light follows geodesics in curved spacetime just as you have been shown.
    Yes, spacetime warps, bends, twists in the presence of mass and energy just as observational experements have shown. eg: GP-B
    Space is not a pure vaccum. Space essentially does not bend...it is spacetime that bends just as you have been shown earlier with photos and experiments.

    It wasn't, so ... well done there.

    Gravitational waves [not gravity waves] carry gravitational energy away into space via spacetime ripples from a coalescing mass or explosion.
    Bullshit.
    The Moon simply falls into the Earth's gravitational warping or well, as the earth [and planets] fall into the Sun's gravitational well.

    No, simply more river ignorance and/or trolling.
    Read up on GP-B as a recent experiment that shows the warping of spacetime due to Earth, and the twisting of the same spacetime due to the Earth's rotation.

    Well, except that the Moon was not captured by the Earth.

    The Moon formed in Earth's orbit.

    Space-time bends but not space ?

    "The space and the time [spacetime ] came into existance at around 10-43 seconds after the BB. Before that we can only speculate as to why and how".post 199

    You going to recognise you lied river?

    Yep, agreed, but you know, having to deal with his continued nonsensical fairy tales, one does less to consider as you have detailed. Point is river most assuredly did not know the evidence shows that our Moon was probably formed after a planetary sized body slammed into a still molten early Earth.

    Considering these two steps, which order do you think makes the most sense?


    First: learn about how things work and how things happen.
    Second: make your own assertions based on how things work and how things happen.

    or

    First: make your own assertions based on how things work and how things happen.

    You talk about how the Moon should or should not have come to be in Earth orbit - and yet you don't even know how it did or did not come to be in Earth orbit.

    Convention tells us that space is what is between the planets and galaxies.
    Convention tells us that time is what separates events.
    The scientific model supporting Einsteins GR, tells us that spacetime is the unified multi dimensional framework against which all events are postured, and stems from the fact that the speed of light is a finite number and constant in all FoR's.
    Spacetime allows a description of reality that is common for all observers in the universe, regardless of their relative motion. Intervals of space and time considered separately are not the same for all observers.
