>>12927456all mass creates a gravity well asymptotic to infinity.
and that is what stretches space time and drives time forward.
as mass accumulates it compound exponentially. and that is why you see space time accelerating as the universe expands.
gravity is the engine of spacetime and its linked directly to mass.
eventually like in a gajillion years, space time will be stretching enough to where it rips atoms apart and converts it to energy. eventually like a gajillion times longer than that event starts, it will rip apart the last atom.
and then it creates a divide by zero event. where peacetime becomes zero. yet the energy exists and all turns into matter instantaneously as space time rebirths starting a "new" universe
