Space is expanding, but not all galaxies are moving farther apart.
In fact, the Andromeda Galaxy will collide with the Milky Way Galaxy in 4 B years or so. Andromeda is much bigger and will probably just absorb the most of the Milky Way. There's a fair chance our solar system will remain intact as we're far enough from the center of the MW Galaxy.
And no... as someone said, the speed of light does NOT change just because the Universe is expanding. It's C, it's a Constant. Does NOT change.
