Current theory is a supermassive black hole.
The North Star is Polaris, out in the same neighborhood we are.

The North Star (Polaris) is nowhere near the center of the Galaxy.
At the center is a supermassive Singularity.

There is a black hole in the center of our galaxy. As black hole cannot be seen, it was found by tracking motion of stars near the center of milky way.
North star is not at the center of anything, it is a star about 400 light-years away from Earth that happens to be aligned with Earth polar axis.

The 'north star' is not at the center of the Galaxy or anywhere near it. It is simply a star that is randomly located very close to the northern axis of the earth. Since the earth spins East-West it remains relatively stable in the sky.
The center of the Milky Way is not north of the earth at all.
A very large black hole supplies the gravity to hold the Milky Way together and helps provide the rotation of the galaxy as well. Black holes are at the center of almost every Galaxy. They are what pulls the matter close together so that the stars and such can form.

A super-massive black hole. It's been proved through observation. It's definitely NOT the north star. The north star is just one of many nearby stars; it just happens to be the one star that lines up with our axis of rotation and so it is the only star that doesn't move in the night sky.

There appears to be at least one black hole at that location. The North Star is comparably very close to us in the outskirts of the galaxy.
