It is possible.


The universe as we know it is the observable universe. That contains all of the stars and galaxies we can see and has a diameter of about 93 billion light years. The universe could be infinite in size, which means that we can only see a small part of it.

The question is, where is the centre of the universe. If it is infinite, the concept of centre is meaningless. We could use a concept such as the centre of mass of the observable universe to define its centre.

Most large galaxies have a supermassive black hole at their centre. The supermassive black holes do influence the evolution of galaxies and may well be responsible for the formation of galaxies.

If there is a large galaxy near the centre of mass of the observable universe then it is very likely there will be a supermassive black hole there.
