Questions & Answers about با این تلسکوپ میفهمیم که فاصله تا آن کهکشان چقدر است.
Why does this sentence use ke (that) and che-ghadr (how much) to mean "what"?
In Farsi, indirect questions are often structured as a dependent clause starting with ke (that), with the actual question word pushed later into the sentence. Instead of saying "we understand what the distance is", Farsi literally says "we understand that the distance ... is how much."
Why use che-ghadr (how much) instead of a word for "what" or "how far"?
Because the subject of the clause is the noun fâsele (distance). In Farsi, you ask for the amount or extent of a distance by saying it is "how much" (che-ghadr). You are literally asking for the quantity of the distance.
Why is the preposition tâ used here instead of be for "to"?
When talking about physical distance, spans of time, or measuring from one point to another, Farsi uses tâ (up to / as far as) rather than the simple directional be (to). The phrase "distance to X" is naturally expressed as fâsele tâ X.
Does mi-fahmim just mean "we understand"?
Primarily yes, but in investigative contexts like using a telescope or solving a math problem, the verb fahmidan also takes on the natural meaning of "to figure out", "to realize", or "to find out."
