Why does the super massive black hole have more gravity?
Quite simply it has more mass. The more mass an object has, the more gravity it will have.
What is the first known black hole?
The first black hole discovered is Cygnus X-1, which was identified in 1964 as a strong X-ray source in the constellation Cygnus. It is a binary system with a massive, invisible companion that is believed to be a black hole about 15 times the mass of the Sun.
What is located in the middle of Milky Way?
The galactic center of the Milky Way is a compact object of very large mass (named Sagittarius A), strongly suspected to be a supermassive black hole.
Is it true a black hole is no more massive that the star from which it was formed?
For a stellar black hole, yes. Mass cannot be created or destroyed. Generally a black hole will be less massive than the star from which it formed, as much of the star's mass gets blasted when the star dies in a supernova. A black hole can gain mass over time as matter falls into it.
Is a black hole massive?
A black hole can have anywhere from 2-3 times the mass of the Sun (the lower limit for a stellar black hole), to about 20 billion times the mass of the Sun (the largest known supermassive black holes).
Is there such thing as big black holes?
While scientists have never actually SEEN a black hole (they are called "black holes" because their gravity is so great that not even light can escape!) we believe that super-massive black holes are at the hearts of most galaxies. These super-massive black holes might be the mass of a million stars the size of the Sun, or larger.
How is the formation of a normal black hole different from the formation of a supper-massive black hole?
It is not yet known for sure how a supermassive black hole acquires the enormous mass it has. It is possible that it starts as a normal black hole, and then gets more mass. It is also possible that from the start, a much larger amount of mass than in a normal black hole collapses.
Is a neutron star or a black hole bigger?
A black hole has more mass than a neutron star, but if you are comparing volume it would depend on the mass of the black hole. A neutron star is estimated to be about 14 miles in diameter, which is larger than the event horizon of a black hole up to about 3.8 times the mass of the sun. A more massive black hole will be larger.
What is the name for the largest black hole and what is its diameter?
We don't have a clue. The nearest black hole to the Earth is a long way away, and we believe that very massive - SUPER-massive - black holes may exist at the centers of many galaxies. How large they might be is entirely speculative. The sizes of black holes are generally estimated by mass, not by distance; "100,000 solar masses", for example. * Added - The name of the largest known black hole is OJ 287 with a mass estimated at 18 billion solar masses.
What are features to include about how big is a galaxy?
how many stars there are in the galaxy its size in light years its mass in terms of our sun[ like 100.000.000.000 solar masses]how big is its super massive black hole in the center and its mass
Does light or mass change into dark light or dark mass as it approaches a strong gravitational force such as a super massive black hole?
It is not believed to be, but there is still very little known about dark matter, so maybe,
How was the massive black hole made in the center of the Milky Way Galaxy?
That is not yet known for sure. Most large galaxies have a supermassive black hole in their center. It is known how a massive star can convert to a black hole, but it is not currently known how such a black hole would acquire such a huge mass since its creation.
