Do satellites in orbit create Relativity paradoxes? [closed]
Can someone point out the flaw in this very realistic scenario below?
I will start by stating established first principles of the applicable orbital and relativistic conditions.
Then I will describe ...

Why don't we put satellites into an orbit where there is (almost) no time dilation/contraction compared to Earth's surface?
Consider:
On this image, if I understand correctly, the time dilation diagram is shown depending on the height for circular orbits. First in low orbit, time slows down relative to the surface due to ...

Explaining the phrase "as viewed by A, clock $\mathfrak B$ appears to be ticking faster than clock $\mathfrak C$"
In writings concerning time dilation and GPS (incl. on PSE) one can find statements such as
When viewed from the surface of the Earth, the clocks on the satellites appear to be ticking faster than ...

Time dilation in general and in particular for two opposite GPS satellites
I am going throw reading on relativity and youtube explanations at the moment.
So far, I got next understanding and some questions:
There is time-space thing. Moving through space at the speed of ...

Why do GPS satellites care about Earth clock at all? (relativity)
Many online resources make grandiose claims about how GPS would be useless without relativistic corrections.
Specifically, they outline that satellite clocks runs slower by 7μs/day due to special ...

Time flow difference for satellites [duplicate]
Clocks in satellites have to be adjusted due to the effects of relativity; but does time for satellites (GPS) flow slower, due to the relative motion, or faster, due to the weaker amount of ...
