Ever wondered what the smell of the universe was? Yahoo! News reports on the creation of a scent that is a scientific attempt to combine all others:
Mixing multiple wavelengths that span the human visual range equally makes white light; mixing multiple frequencies that span the range of human hearing equally makes the whooshing hum of white noise. Neurobiologist Noam Sobel from the Weizmann Institute of Science in Israel and his colleagues wanted to find out whether a similar phenomenon happens with smelling.
The smell is dubbed “olfactory white,” because it is the nasal equivalent of white noise, researchers report today in the journal Proceedings of the National Academy of Sciences. What does olfactory white smell like? Unfortunately, the scent is so bland as to defy description. Participants rated it right in the middle of the scale for both pleasantness and edibility. “The best way to appreciate the qualities of olfactory white is to smell it,” the researchers wrote.
