“The ceiling is the roof,” is what Michael Jordan said on Saturday about the direction of the North Carolina football program causing the Internet to explode.

 And while the crowd at the Dean Dome exploded in excitement (further proving M.J. could say literally anything and UNC fans would rejoice), social media had a feeding frenzy with it.

But at least one professor is coming to Jordan’s defense -- and he’s getting backup from an unlikely source: An engineering professor at rival Duke.

“So the traditional dictionary definition of a ceiling is the surface on the inside of the room,” Henri Gavin, a civil engineering professor told Bleacher Report. “That’s what the ceiling is. The roof is the surface that covers the building. But an arena is one giant room, so the ceiling is the roof.”

He explained: “If you look at the top surface of the arena from the inside, you would call that object the ceiling,” Gavin said. “If you looked at that same object from the outside, you’d call it the roof. The ceiling is the roof.”

There you have it, for all you “ceiling isn’t the roofers” out there. The ceiling, according to an engineering professor from Duke, is in fact the roof.
