It is like a wave that consciousness as build by the brain makes its way through the space time curvature as deemed fit. The consciousness having no mass but energy like a photon travels through the space travelling at speeds higher than the speed of light which is the propagation of photon itself. Thus consciousness travelling to the distant stars having found no reason for its own existence makes the individual aware of his own reality on the earth The time plays important role as the consciousness causes the curvature in space which causes the gravity and time running slower causes the consciousness to mold the space as it deems fit unlike when the space time continuum to be considered uniform. So its time that causes the curvature of space as it deems fit and preserves the reality of nature itself.What is the cause of curvature in space is not gravity but the time dimension as ticking at the precise motion of itself and a little slowness in it would curve the space-time curvature differently.
It is the consciousness that makes the sky appears as it appears though in reality if the earth is viewed from the top, the space would appear as a road stretched between the heavenly bodies rather than a flight into the sky. So the curvature in space is caused by the consciousness of the space which appears uniform because time is not running slow.
It is the mass of the earth that curves the sky and it is the consciousness that causes curvature in the space and it is the curvature of space that curves the gravity.
Self-referentiality of consciousness as describing itself in the space according to time could be studied as lacking the ideal knowledge of the system that makes us study the physical system from outside of ideal knowledge. That is we study the space time curvature from the incompleteness of the ideal knowledge of time.
