Storytellers crossing the Galaxy's boundaries, moving huge distance? (5,5)

'huge distance?' is the definition.
'light-years' can be an answer for 'distance?'. I'm unsure of the 'huge' bit.

'storytellers crossing the galaxy's boundaries moving' is the wordplay.
'storytellers' becomes 'liars' (I've seen this in another clue).
'crossing' is an insertion indicator (to cross can mean to go over or around).
'boundaries' says to hollow out the word (remove centre letters) (only the edge or boundary letters remain).
'moving' is an anagram indicator (letters are moved around).
'galaxy' with its centre removed is 'gy'.
'the'+'gy'='thegy'
'thegy' anagrammed gives 'ghtye'.
'liars' going around 'ghtye' is 'LIGHT-YEARS'.

Can you help me to learn more?
