If I bend a paper, it doesn't change the things written on it.(adsbygoogle = window.adsbygoogle || []).push({});

If gravity is bent space(time), we shouldn't be able to detect it. (e.g. things shouldn't be dragged by it)

So why are we talking about bending space, if it's not the space itself that is bending?

it's only our mental concept of how things will be that is "bending".
