Inside normal UFO, possibly, covering space and time (4-11)

Ross

I believe the answer is:

four-dimensional

'covering space and time' is the definition.
(time is sometimes considered the fourth dimension)

'inside normal ufo possibly' is the wordplay.
'possibly' indicates an anagram.
'inside'+'normal'+'ufo'='insidenormalufo'
'insidenormalufo' is an anagram of 'FOUR-DIMENSIONAL'.

I've seen this clue in The Guardian.
