|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 ?
|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 !
