Tanmay,
That is an interesting conceptual connection between final stage gravitational effects and biological death. If I may riff off that somewhat, I draw similar relationships, but use a different conceptual frame.
In my entry, I make the observation that we perceive time as a sequence of events from past to future and physics re-enforces this view by treating it as a measurement issue, but the underlaying physical process is the changing configuration of what exists, turns future potential to present actual, then past residual. Not the earth traveling a narrative dimension from yesterday to tomorrow, but tomorrow becoming yesterday because the earth rotates. Duration then is not a dimension transcending the present, but is the state of the present between events.
So in this view, while the present goes from past to future, alternatively, events go future to past. Now think how this applies to life; The unit of time that is the individual life starts in the future, exists in the present and then dying, fades into the past. Meanwhile the species has moved onto the next generation, like the hands of the clock move onto the next unit of time.
Consider this in terms of a factory: The product moves from start to finish, while the production process points the other direction; Consuming raw materials and expelling finished product.
Our minds work like that as well. Consuming information and creating thought, which then are replaced by the next and fade into the past.
Our bodies as well are processes of generations of cells that form, go about their functions and then are shed, as the body lives.
In very basic terms we have energy manifesting information and information defining energy. In fact our bodies consist of two integrated systems to deal with both side of this coin. The central nervous system and the senses process information, while the circulatory, digestive and respiratory systems process energy. both integrated to manipulate our limbs and actions to gather more energy and information.
Yet energy is ultimately conserved. It is the state of the present, that which the energy is activating. So in order to create new information, old information is erased. You really can't have your cake and eat it too. Time then emerges from this creation and dissolution of energy.
So how does this tie in with your relating gravity to death? The past is that which is ordered, while the future is where the energy goes. Once structure has reached its apex of structural potential, the only path left is decline. Entropy only applies to such closed sets. Yet as structure looses energy, the remaining structure becomes ever more dense. As heat and light radiates away, what is left is crunched down to ever more solid structure.
Meanwhile that light and radiation expands out to create, expand and grow new structure. So the radiant energy is the arrow of time that points from past to future, as the gravitational density of mass is what coalesces out of future possibility and becomes residually harder. Until it too falls into that final gravitational vortex and is shot out as jets of cosmic rays, for billions of lightyears. So the cycle starts over again.
I do see math as simply modeling reality, rather than the basis for it. (It's information.) So black holes and singularities are not real, but models of this infalling process. So what is gravity? When mass turns to radiation, it creates pressure. Just think of the shock wave of an atomic bomb. So what happens when energy fuses into mass? Wouldn't it create a vacuum? Since nature is not fond of vacuums and fills them in, the result is gravity. Consider they haven't found dark matter, but there is lots of unexplained cosmic rays throughout the galaxy. Could they, in the near absolute zero of interstellar space, be coalescing into gases? Which then continue to coalesce into mass, which then is getting ever more dense, thus constantly creating more vacuum? It would explain why no gravity waves have been detected, because it is all around us, as the radiation being created by fusion.
Since the absolute is basis, not apex, a spiritual absolute would be the essence from which we rise and return, not an ideal from which we fell and seek to climb back up. That essence simply pushes the reset button fairly regularly and the cycle of gathering information and structure starts over again.
I could continue, but I was just trying to connect gravity, the past and death.
