Can the galaxy implode at any moment?

    No.

    A galaxy is a whole bunch - gazillions - of stars and stuff in orbit around a common centre. It reached this equilibrium point through millions (often billions) of years of things either going into stable orbits, or being thrown out of the galaxy (for going beyond escape speed) or falling into the centre (for not going fast enough).

    What you see is the result of this stabilization.

    IF (this is a big if) something should happen to break the equilibrium, it would take millions of years for "whatever" to happen.

    In our case, our Galaxy will interact with the Andromeda galaxy in (roughly) three billion years. Although we call that a collision, there will be very few actual star-on-star collisions (there is simply that much space between each stars).

    However, due to tidal effects of one galaxy on the other, some streams of stars will be (very slowly) thrown out, while others will fall into the black holes at the centre of each galaxy. Most of the stars will simply enter into chaotic orbits (they will stabilize over millions of years) to form an elliptical galaxy.

    Of course, whatever happens to a star will entrain its planetary system (the planets simply go along for the ride).

    This is so slow that an average human being living an average lifetime will not notice any difference.

    Not really.

    First, there is the size. Even at SOL it would take thousands of years to "implode."

    No. It is stable and has been stable for 10 billion years.

    Assuming that an implosion is possible it would take billions of years. First, the Milky Way's central black hole would have to cannibalise the stars circling it. That alone would take aeons. After that the parts of the spiral arms nearest the black hole would be affected. Again it would take millions of years for those stars to be digested. While of this is going on in the galaxy itself other dwarf galaxies such as Canis Majoris would continue to be cannibalised. AND do keep in mind that the Andromeda Galaxy is on a collision course with the Milky Way and the merger of these two galaxies would happen before the Milky Way imploded.

    Any moment,,hardly. Should our galaxy up and collapse into that super massive black hole at the center,

    it would take about 75 million years to do so.

    A great many stars have already became BH fodder, so a very slow thing indeed.

    No

    The Universe would have to begin to Implode first

    No, if that happens , it will take dozens of billions of years

    Not really... they're a bunch of stars & gas orbiting a common center; unless that motion would suddenly stop (and I'm not sure how you'd stop a star...), it should just continue for billions of years.

    I heard that the Galaxy Note can EXplode but this is the first I've heard of any Galaxies IMploding.
