The best place to smell this particles is when you crack open a freshly boiled egg. Someone said gravity was a wave function and therefore had no smell. Well, if gravity is a wave function, how can a Black Hole exist Mr. On the other hand, gravity exists in a vacuum, and the only thing you could smell in a vacuum would be the blood as your blood vessels in your nose explode. Not that that's what I'm saying that's what gravity smells like.
Gravity smells like white.
Of course, you may say that invection and convection, as well as prevailing winds, may have some effect on the rise and fall and dispersion of certain smells, but we are talking about the smell of gravity under controlled conditions. I would like to go further into this by discussing the relative molecular structures and weights of these smells, and how those would relate to the effects of gravity upon them, but I seem to have misplaced my Periodic Table of Smells. When I find it, I'll post again. Gravity smells like a cave - or dirt.
