Adapting Universal Constants...En route To A Single Law ?

Do these universal constants, intricate
values change over time ?
Gathering from the previous post, what could the consequence of the variations in the gravitational law depending upon the expansion of the universe and the dynamic nature of spacetime mean ? For one, this critical value of acceleration mentioned C^2/R,('C' speed of light, 'R' Scale of the universe), occurring wherever leads to phenomena which we generally wouldn't observe, an insight I gained from this could be the changing nature of constants. In other words the evolution of the entire universe, to how we see it today. The universe is undergoing an accelerated expansion. Therefore the connected and related value of C^2/R changes over a significantly immense period of time owing to the dynamic nature of ‘R’. Now this is interconnected to the orbital accelerations of the stars as shown in the previous post. The stars would fall out of orbit and the entire galaxy would

Do fundamental laws change ?
collapse in on itself, provided this value were to change even by a slight value. But this happens in a time scale quite colossal compared to even the time scale of creation of our solar system. Hence this leads to other consequences, if the value of the gravitational constant changes it being related to the expansion in spacetime, the changes should be reflected by the properties of matter lying within spacetime as gravitational constant is associated to matter. If matter’s properties are changing over this period of time, the remaining forces, laws, and constants governing their interaction, formation and appearance must also change with time. Everything hence in the world should be relative and is relative as seen in maximum cases. Thereby pointing to the fact that even these constants aren’t absolutely constant but just so within the conception of our (short) existence in the universe. This further leads to conclusions such as if the constants are changing overtime, the universe could have evolved into its present state like the evolution of humans from the single celled organism through constant adaption. The constants could have adjusted overtime to have attained the value they have as we observe them now. The value so attained so as to make sure the existence of the fundamental entity is not compromised. The entities of nature matter, forces, fields, would have corresponding to their environment provided by the dynamic spacetime fabric adjusted themselves accordingly to attain stability and gain the necessary values to sustain. Here I would like to mention the post the ‘Atomic life force’. From where I concluded that the very existence of the basic entity could itself signify a fundamental law.
An Evolving Universe ?

This could be one of the answers as to why the 20 constants in the Standard Model of Particle physics are fine tuned to these exact values, because they have  gradually adapted to these values overtime so as to work in perfect synchrony. Once they work in sync by adjusting to values to attain a universal balance, thereby not causing the universe to collapse into nothingness or spin out of control, they secure their existence in the universe. Now as expansion occurs slow stretching of the spacetime fabric’s fundamental entities to allow for the expansion might be occurring, this would lead to a point where sufficient stretching could reveal the true nature of spacetime. To probe  ‘empty space’ and reveal its true relationship with matter is an ongoing quest that is hot caught in the web of String physics which incidentally, leaves inquisitive ones dazed and puts up more questions than it answers !
