What we need to do is ask those poor bastards who got stuck up in the Mir Space station in zero gravity for a long time if they noticed any strange lack of smell or noticed anything different when they got back. Well, we must first define what gravity is. Newton said it is an attractive force between two masses, while Einstein said it is due to the shape of space-time around a massive body. Therefore we conclude that gravity is due to the massive force around the shape of space-time inside a massive body. Therefore there is no gravity and there can be no smell.
Experiment suggests that gravity is particularly strong in New York.
But if you prefer the quantum theory of gravity, then gravity is actually caused by little elves, similar to Santa's, called Gravitons, who grab hold of things and pull them down as hard as they can. The mathematical part of the theory centers around Bernhard Riemann's discovery that one plus one equals three, for large values of one. Gravity, smells nothing like this. Mr. Weers Everyone know that gravity smells like salted nut rolls mixed with silly string in a couldron formed from spam can. I've talked to many.
