The supermassive black hole at the center of our own Milky Way galaxy , Sagittarius A*, weighs in at around 4.1 million solar masses.. which calculates to a radius of about 8 million miles. By comparison, Mercury gets as close as about 28 million miles to the Sun.

Why does Sagittarius A indicate that a black hole is at the center of the universe?
Sorry, the universe does not have one center. According to the usual interpretation of the Big Bang theory, any and all points in the universe can equally be considered centers of the universe.Perhaps you meant to ask "Why does Sagittarius A indicate that a black hole is at the center of the Milky Way Galaxy?" instead. Galaxies do have distinct centers, all spiral galaxies are now believed to have a supermassive black hole at their centers, and our galaxy: the Milky Way is a spiral galaxy. The observations of the object called Sagittarius A match what would be expected of a supermassive black hole and are in the right galactic direction to place it at the center of the Milky Way galaxy.
How big is Neptunes Black hole?
Neptune does not have a black hole
Is the number of stars in the Milky Way Galaxy evidence in support of Big Bang Cosmology?
no the no. of stars in the milky way is not the evidence in support of the big bang cosmology.
How big is a super-massive black hole?
The mass of a "supermassive" black hole can be anything from "stupendous" to "mind-boggling". The black hole at the center of the Milky Way may be as massive as a million Suns, and our theories of physics do not, as yet, indicate a maximum mass.The physical size, as in the diameter, may not be a valid concept when we're talking about black holes. We do not yet understand enough about how things work to understand what goes on near a black hole.The in the centre of a black hole the mass density is infinite measuring 0 cm in diameter. No matter how large the black hole is, light cannot escape at a speed of 299,792,458 meters a second...According to Newton's second law of motion, F=ma. This equation involves objects with a fixed mass to be attracted to another object but with a greater mass.
Can a black hole suck in the universe?
Unlikely. The universe is a very big place, even next to the largest black holes we know. For a black hole to suck in the entire Universe, it would need to be nearly as massive as the universe itself. There is no way that such a black hole could form.
How big is the middle of the Milky Way?
The middle of the milky way is a black hole and a black hole cannot be made up as matter. The middle of the milky way has no size, but the black hole sucks the light making it look big in pictures. The actual size is nothing.
Where in space is blackhole?
There are many black holes in the universe, and they are generally in the very center of a galaxy. Our Galaxy, the Milky Way, has one big black hole in the centre of it.
Is the universe expanding or is the milky way being drawn into a black hole and how would one tell the difference?
The universe is expanding but I'm not too sure about the second part. The obvious thing is that a black hole looks like a big black hole.

Who made the Milky Way?
The Big Bang made the Milky Way galaxy.
Will the galaxy ever get sucked in to a black hole?
no the galaxy is way to big for a black hole to do much in fact we now know that there is a supermassive black hole in the center of our galaxy right now.
Which star in the galaxy is a giant?
There are lots of giants in our galaxy. Betelgeuse is very big (about 20 of our Suns). The massive object / system (expected to be a supermassive black hole) at the center of the Milky Way has the mass about 2.6 million of our Suns.
How big is Neptunes Black hole?
Neptune does not have a black hole
Which is the big galaxy?
the milky way
Which is a big galaxy?
the milky way.
Can a black hole destory the galaxy?
No. No black hole is big enough to do that.
Can your universe just be at the end of a black hole and can the big bang just be the birth of that black hole?
Actually one interpretation of the big bang is as a white hole, the inverse of a black hole.
