@IrishBoy123   what confused me about the question is dont u have to measure the distance from going to coming ? so like take the distance and timising by 2 ?

anonymous · Answer

what makes this question different?

irishboy123 · Answer

**distance from going to coming**

that to me does not really have any meaning.

this is a simple skit about the fact that light itself has a "finite" speed.

so, the amateur astronomers assumed instantaneous light , and worked out something different.!?  

not sure this helps too much.
