As the image shows, the sky of some planet in the deep future (4 billion years from now) and in another galaxy will be filled with the slow collision between our galaxy, the Milky Way, and Andromeda...



Yes, the universe (meaning space) is expanding at a faster and faster rate, but local galaxies are coming together and will one day form the only universe that can be known. Distant galaxies will be gone, and this one galaxy will be surrounded in blackness. And the most brilliant minds of whatever is living at that time (a time when our star will be dead) will have theories of the universe that are not dissimilar to those of the Middle Ages in Europe. What our minds of today contain will not be found in the minds of that distant tomorrow. Those most other modes of thinking and reflecting just cannot know that faraway galaxies were pulled into a rapidly expanding nothingness that kills even the shumba of the universe, the speed of light.
