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 ...

Question regarding Time dilation of satellites
My name is Shaun Kant.
I was wondering about why the satellite's time is faster with respect to Earth's time. PBS space time mentions that fact. However, Wikipedia mentions that at the ISS (...

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 ...

Time dilation inside International Space Station
SR tell us that inside ISS time is running slower than on the earth. But velocity is relative. We can choose to consider either ISS or earth to be at rest. An observer inside ISS sees the earth ...

What is the orbital angular velocity of a satellite?
Angular velocity ω is by definition the runned angle $dθ$ per time $dt$ elapsed: $ω=dθ/dt$. If the time elapsed in a specific point on the earth's surface is $dt$, the dilated time elapsed on ...

Is Sergei Krikalev living slightly in the future, or is his body just younger than it otherwise would have been? [closed]
Due to cosmonaut Sergei Krikalev's time on board space station Mir in Earth orbit, the combined effects of velocity and gravity have caused him to experience an accumulated 20 milliseconds of time ...

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 ...
