The Saturday Morning Post : Some things Need a Little Explaining

What is going on in this image. It isn't a very steep staircase into a ceiling.  

My office was asked for input recently on an ethics question.  I circulated the question and got two opposing views, one said the rule is far to liberal and a danger to all who go near, and one it is far to restrictive and a danger to all who go near.  And both are valid points of view.  I can explain both.  

I am sorting out my office, getting ready for a new office sharing arrangement.  I am bringing home some personal items I have accumulated over the years, one was a little sign that reads, "I can explain it to you, but I can't understand it for you." Kind of rude, but I like it.  

Many of the things we see in life, that we hear in life, that don't make sense, might with a little explanation.  We can explain, understanding is an inside job, like happiness.  

So what is happening above.  It is a stone and concrete staircase from the underside.  What looks like a ceiling at the top, is where the top of stairs join the floor above. You would climb up the other side of what you are seeing. The windows, are a skylight.  This was taken in an aboveground metro rail (subway) station, looking straight up.  Does it make more sense now?
