The cumulative gravitational potential originating from mainly the outer masses of our visible universe is about 8 orders of magnitude larger than the Sun's gravitational potential at the Earth's distance, which also holds all other planets on track. Remarkably, the potential energy of a mass m at the level of gravitational potential originating from the masses of remote parts of our universe is of the order E = mc^2.

In Physics, It is very challenging to objectively respond to ''the why question'' (no matter how good might the answer be, one would still have a right to ask why)... nevertheless, Mach's principle has been tested and found to be false.

@ Olivier Hakizimana
Fortunately, your cited paper does not prevent our Sun from providing a gravitational potential which keeps us in orbit. I think that even remote stars of our universe also have a gravitational potential as pointed out in my initial question, quite independent of what people understand by Mach's Principle.
Just a reminder:

Dear Johan,
Local physical laws are determined by the large-scale structure of the universe... that is what is generally understood by Mach's principle, which is vague by the way.
Unfortunately, that false Mach's principle has everything to do with remote-masses, just like your question.
Dear collogue. Do you think our universe with billions of galaxies where each galaxy situated in modern distance as complete entity or it is accidently of big bang?

Dear Javad, depends on what you mean by the word “big-bang” and how sure you are “It ever happened in the past” (that’s why we need radiations to spot the past)
As for now, we are all part of an accelerating rotating entity which appears to be finely-tuned instead of an accident.
