Questions & Answers about Han gikk hjem uten at han sa noe.
Because the sentence is in the past tense.
- går = go / is going
- gikk = went
So Han gikk hjem means He went home.
In Norwegian, hjem often works like the English adverb home.
- Han gikk hjem = He went home
You do not usually say til hjem.
That would sound unnatural, just like went to home sounds unnatural in English.
Compare:
- Han gikk hjem = He went home
- Han gikk til huset = He walked to the house
