I do not understand, why every time when we talk about the speed of light it is tightly coupled to time.
As well, as I do not understand this statement
> The issue comes if you start moving. In relativity, from your perspective, you are standing still while Earth appears to be receding.
Maybe because of a lack of knowledge.
Is there any good reason to think that the speed of photons differs from that of other objects?
I see only one reason for this kind of statement, that we do not have the ability to measure processes faster than the speed of light, because right now we don have the ability to do measurements or collect information from observation faster than the speed of light,
People cannot observe faster than the speed of light, moreover, we cannot measure the process of movement of something faster than the speed of light just because humans can't retrieve information faster than the speed of light.
And so we believe that the speed of light is related to time,
But it is connected only with time, where a starting point is a person, not the universe.
I don’t understand why the fact that we can’t do something, due to purely technical limitations, becomes a postulate about how the universe works.
