Questions & Answers about جاذبهی سیاهچاله آنقدر قوی است که نور هم نمیتواند فرار کند.
How does the "so... that..." structure work in this sentence?
The phrase ân-ghadr means "to that degree" or "so much". It is placed before the adjective ghavi (strong), and followed later by ke (that) to introduce the result. Together, ân-ghadr ghavi ast ke translates to "is so strong that".
The lesson says the verb after ke should be indicative, so why is farâr konad (escape) in the subjunctive?
The rule is that the main verb of the result clause must be indicative. Here, that verb is nemi-tavânad (cannot), which is indeed in the present indicative. However, farâr konad is the second verb in the clause. Because it directly follows a form of "to be able to" (tavânestan), it is forced into the subjunctive mood.
Why does ham mean "even" here instead of "also"?
The word ham generally means "also" or "too" in Farsi. But when used to emphasize an extreme limit, especially in a negative context like this one, it translates naturally to "even" in English. Therefore, nur ham means "even light".
How is the word for "black hole" formed in this sentence?
The word siyâh-châle is a literal compound made just like its English equivalent, combining siyâh (black) and châle (hole or pit). Notice that an Ezafe suffix is needed to link "gravity" to it, creating the phrase jâzebe-ye siyâh-châle (the gravity of the black hole).
