By observing the movement of nearby objects. The gravity of the black hole will accelerate such an object according to Newton's Second Law (F=ma). More specifically, the details of the orbit of a star that moves around the black hole will vary, depending on the black hole's mass.
Astronomers hypothesize the presence of a supermassive black hole at the center of the Milky Way because of the high velocities exhibited by stars orbiting the region and the intense radiation emitted, which is characteristic of black hole activity. Additionally, observations of other galaxies suggest that supermassive black holes are common in galactic centers.
Adverb: "A black hole forms when a supermassive star collapses after a supernova explosion."
The supermassive black hole that hosts the galaxy NGC 1277, in the constellation Perseus, is currently the largest black hole in our visible universe with a mass equivalent to 17 billion suns. In 2012, astronomers have discovered this small galaxy about 250 million light-years from Earth.
None, really. At least, for us, and now. A black hole can be dangerous if it's very massive (such as a supermassive black hole). But mainly, a black hole would be completely harmless, unless it gets close - and the nearest known black hole is at a distance of about 3000 light-years. Even a supermassive black hole would be harmless at such a distance.
No, the biggest quasar is not capable of destroying the biggest supermassive black hole. Quasars are powered by the accretion of material onto supermassive black holes, so they are closely related. The interaction between a quasar and its host black hole is complex but does not result in the destruction of the black hole.
Astronomers believe a supermassive black hole lies at the center of the Milky Way galaxy because of the high speeds of stars and gas near the center, as well as the intense radiation emitted from that region. These observations suggest the presence of a massive object that can only be explained by a supermassive black hole.

No, a supermassive black hole is what makes a quasar.

A Supermassive black hole .
The very center is believed to contain a very powerful black hole.
Quasars have a large black hole, called a "supermassive black hole". The term "supermassive black hole" simply means that it has millions or even billions of solar masses.
The song that is played in Twilight when the Cullens play baseball is 'Supermassive Black Hole' by Muse.
Yes. In simplistic terms, a quasar is the result of a supermassive black hole. The gravitational attraction of the supermassive black hole on the galaxy, causes the effect of the quasar. See related questions for more information.
