    Correct river!!! A star for you!!

    But spacetime does bend/warp/curve/twist in the presence of mass/energy. Or as I have explained to you many times, the geometry of spacetime, is gravity.
    Here is an extreme example called an Einstein cross. The four images you see river are one and the same object.

    Geometry in spacetime is meaningless .

    Do you understand why , pad ?

    Nonsense river. Do you understand what geometry is? Do you understand topology? Do you understand that when flat spacetime assumes other geometrical phrases, in the presence of mass/energy, we get gravity? Do you understand the illustrations I have given? Do you understand that GR is tried and tested, and has been validated many many times?

    If you would like to learn more, read up on the science.

    Sorry river. You can avoid being continually made to look foolish by reading up on science if you wish?

    General relativity is a complex theory, but imagining falling objects can help trace its contours. (Here, GPS satellites are shown around Earth — GPS depends on relativity to give accurate positions.)

    Or if you like river, I can get a link/s on the GP:B [Gravity Probe B] this was a satellite that verified the Lense-Thirring effect. Or the twisting of spacetime by the revolving Earth.
    I,m here to help river.

    You have said plenty to indicate that you are ignorant and wrong about what you stupidly claim.

    here river....
    Stop painting yourself into a corner river old mate...It does, 100% make you look foolish and made even more obvious by then trolling, when you are confronted with verifiable evidence showing your errors and mistakes.

    You have no idea why pad . Do you .

    Give it your best shot pad .

    OK river, I don't want to grill you anymore then what I have....
    But you really need to take some advice when shown to be wrong...own up, be a man, don't lie, don't troll, because they are what you have had holidays for, and been banned from the sciences.

    Well without any physical reality existing first ; then where does geometry and space-time reside ?

    Go learn some science river and stop making a goose of yourself.
    Firstly as any student knows, scientific theories are models, supported by observational and experimental evidence. Something need not be physical to be real, is another aspect of your ignorance.
    Spacetime river is the multi dimensional framework within which we locate events and describe the relationships between them in terms of the three spatial coordinates and time. The concept of spacetime follows from the observation that the speed of light is invariant, that is it does not vary beween the emmiter and the observer.
    Aspects of space and time considered separately are not the same for all observers, and are interchangeable.
    In GR gravitation is described in terms of curvature/warping and twisting of spacetime as per the evidence I have already given you.
    You can sit there and wilfully deny that for as long as you like river...it changes nothing except maybe drive you further along the path of permanent banning for your wilful trolling and unsupported pseudoscientific claims.
    Space is real river, thankfully it is what exists between you and me at this time.
    Time is real river, its what stops everything from happening together.
    Both while being non physical entities are still real, just as the framework of spacetime is real within GR, our accepted model of gravity.
    That will stand for quite a while, and until at least we have a QGT, and even then should be encompassed by such a QGT theory.
    At least you are justifiably banished from posting your dribble in the sciences, of that this forum has plenty to be thankful for.
    You have a good day river in your self gratutitious gullible nonsense. It's all you have.

    Not really. I'm OK and still have access to the sciences.
