"The word's room". So nice :)
I think it's "world's room" as in "interplanetary space"
Doesn't the fast version leave out "det"? I can only hear "hvorfor er ikke luft i verdensrommet".
The "det" is there, but it blends in with the "ikke" so it sounds a bit like "d'ikke." This can happen in natural speech.
Thank you. I listened to it again and again, but still – I cannot hear it. I probably need to further train my ear to recognise such subtleties in natural speech.
