Observation of Orbital velocities suggests that there is a super massive balck hole at the core of most if not all galaxies.

They have discovered that every galaxy does have a Super Massive Black hole at the center. However, they do not yet know the full relationship between the two (chicken and the egg kind of arguement, did the black hole come first of the galaxy).

In theory every rotating galaxy whether globular or disk shaped rotates around a super gravitational core that contained a central void consisting of either 1 or a (presumed to be odd) number of rotating black holes it is said that 5 small black holes rotating around each other in the center of a galaxy would result in the most stable and gravitationally balance configuration.. there would be individual event horizons around each black hole (the point of no return) plus a more vague semi-event horizon outside the group of black holes after passing which any matter is destined to end up in one of the black holes depending on its speed and trajectory.
however items outside this semi-event horizon will be drawn into the main body of the galaxy cluster due to an overall outward gravitational pull.
some proponent even state that galaxies are really like donuts in shape as the central black hole become too massive and either supernova or slip into another dimensional universe generating wormholes in space..

The milky way does and many other galaxies do. But whether you can have a galaxy without a black hole, I'll have to guess yes.

Probably not. A large number of spiral galaxies like our own Milky Way have been shown to have black holes at their centers. But until astronomers can look at every single galaxy in the universe (...not likely) no one can say that they all have black holes at their centers.

Scientists think that there are black wholes in the middle of each galaxy and some through out the universe when stars collapse on them selves a great force is grown there for sucking in everything in. They think that inside of it nothing exsist anymore and the rules of space are broken. Some are small and undetected but as i said the big ones are in the middle of galexies. There power is untable and we dont know how to deal or checkone out .These are some of the great mysteries of the universe.

Current thinking seems to be leaning toward the idea that all galaxies have a massive hole at the center.

Black holes have not been proven it is hypothetical. In theory they should exist.
But have not detected one 100%, they only notice it’s affects by a gravity lens, since Black holes do not emit light, we can only observe there effects on its surroundings
They suspect that every galaxy has one, but that is theory only.
go to the NASA web site, they have tons of info

yes, to have a galaxy you have to have a black hole

It is believed that most, and possibly all, galaxies rotate around a central supermassive black hole.
