The term complex carbohydrate was first used in the U.S. Senate Select Committee on Nutrition and Human Needs publication Dietary Goals for the United States (1977) where it was intended to distinguish sugars from other carbohydrates (which were perceived to be nutritionally superior).
The SMBH at the centre of the Milky Way is of 4.1 million solar mass, whereas the nearby Andromeda Galaxy contains a SMBH of 110-230 million solar mass. The largest SMBH in the Milky Way's vicinity appears to be that of the galaxy M87, containing 6.4 billion solar mass. The largest SMBH in the nearby Universe yet found is that of the galaxy NGC 4889, containing 21 billion solar mass.
Located almost a billion light-years away, IC 1101 is the single largest galaxy that has ever been found in the observable universe. Just how large is it? At its largest point, this galaxy extends about 2 million light-years from its core, and it has a mass of about 100 trillion stars. Some estimates suggests that IC 1101 is 6 million light-years in diameter. To give you some idea of what that means, the Milky Way is just 100,000 light-years in diameter.
