I just don't get it.

According to the theory of special relativity, nothing can ever move faster than light speed.
But due to the expansion of the universe, sufficiently distant stars move away from us faster than the speed of light.
And the explanation is...that this universal speed limit doesn't apply to things that are really far away?
Please make it make sense!

Make sure your answer comes from a cosmologist, not a cosmetologist! They sound similar, but I had to retake AST1430H Cosmology, because I consulted the wrong sources.

Don't get me started on my mathematologist friend.

My cosmetologist told me I should get rid of my black holes before any light hits them.

My Cosmetologist told me I need to realign my chakras because Mercury is in retrograde.

Are you a Taurus by chance? My Astronomy teacher told me I'd be meeting someone like you today at our last reading.

I hope you're looking for a new one that isn't so racist.
