I can’t stop watching this. A simulation of the eventual collision of the Milky Way and Andromeda Galaxies.
Space makes so much more sense to me when sped up. As scary and violent as it seems, there would be very little colliding actually happening due to the insane amount space between objects.
from Wikipedia: While the Andromeda Galaxy contains about one trillion (1012) stars and the Milky Way contains about three hundred billion (3x1011); the chance of even two stars colliding is negligible because of the huge distances between each pair of stars. For example, the nearest star to the Sun is Proxima Centauri, about 3x107 solar diameters (4x1013 km or 4.2 ly) away. If the Sun were a ping-pong ball in Paris, the equivalent Proxima Centauriwould be a pea-sized ball in Berlin (and the Milky Way would be about 1.9x107 km wide, about a third of the distance to Mars).
