You mean GALAXY chochlate yaa, By watching wrappers on the floor.

I thought this was a pretty good answer that made sense to me:
"In the cold dark matter paradigm, "halos" of dark matter first become gravitationally bound and "break away" from the general expansion of the Universe; that is, instead of expanding with the Universe, the Universe expands around the halos. Each halo (of galaxy size) will end up as a galaxy at some point: so in a sense, these primordial halos represent represent the "birth" of a galaxy. Once a halo is formed, normal (or "baryonic") matter falls towards its centre, because of the gravitational pull that the halo exerts. During this infall the baryons must conserve angular momentum, and so they begin to spin faster around the centre of the halo as they fall deeper into it. This process yields a disk of star-forming, normal matter inside a halo or dark matter, as we seem to observe in spiral galaxies today."
Summary: There is a center graviational pull (i.e. the sun) and the galaxy's planets rotate around it (i.e. pluto is the last (known) planet in our galaxy that rotates around the sun). Therefore, the definition of beginning & end is where the center is and the last item that rotates around it.

Galaxy rotates which identifies its end. Galaxy is a group of star which are close distance. Our galaxy are spiral. And can be identified in the sky in night without telescope. There is a belt of much more shining star compare with other star. All constellations are lies in this belt are our spiral shaped galaxy. The shining and size of star identifies the begin and end of galaxy.

Wide open space.
The size of our galaxy is 12,000 light years.
The nearest galaxy to us is 2.6 million light years away.
This means that if our galaxy was the size of a football placed on the goal line, the nearest galaxy would be at the other end of the pitch. With nothing in between.

This is actually easier than you'd think....there are MASSIVE gaps between the galaxies we can see.
Get yourself a good telescope & a sky map that shows the locations of the easiest galaxies to see, (or check the link for kids below) and you'll see what I mean.
Happy star-gazing!

Probably space. Galaxies are clusters of stars. The cluster is much further away from other stars than the starts inside the galaxy are from each other.

It's kind of fuzzy, but essentially there's just a lot of open space and therefore a galaxy ends (or begins).

They just look to see where the gravitational influence of the galaxy ends.

I believe that in space there is a cluster of stars and planets and when there is a gap between the clusters thats when galaxys are created.

The influence of gravity around the surrounding objects. Just like the Sun's influence on planets within a solar system.
