This we see in the behaviour of objects in space. So way down where sub atomic particles seem to become ethereal things that seem to have effects rather than existence, the space-time continuum has shape. And this, I suspect, goes on ad infinitum. So here we are in our relative position looking out to the macrocosm and in to the microcosm. What we react to, where we get out experience is from the interaction of all this mater .
Living systems are hugely complex systems of atoms and molecules.
Their interactive behaviour all being based on the warped space-time that they are. So for a moment imagine a planet floating in space. The zone around this planet is, like the rubber sheet, stretched. Space-time is denser closer to the planet. This effect is the consequence of the huge density of the atoms in the planet.
