Actually, our very own Milky Way Galaxy might be on its course to a collision with the Andromeda Galaxy; though I gather that eventual future generations shouldn't have anything to fear:

The students fear that this may be the end of life, as they know it. But, their teacher reassures her class that there is very little chance of stars from the Andromeda galaxy hitting the Sun or the Earth. Even though the galaxies pass clear through each other, she says, stars in a galaxy are spaced very far apart.

The text does not mention anything about potential new hypernova candidates created due to the compression of the gas that could scorch the Earth a while after the collision have started; but I don't know.
