Galactic Cannibalism

Like life on Earth, galaxies can "eat" each other and evolve over time. The Milky Way's neighbor, Andromeda, is currently dining on one of its satellites. More than a dozen star clusters are scattered throughout Andromeda, the cosmic remains of past meals. The image above is from a simulation of Andromeda and our galaxy colliding, an event that will take place in about 3 billion years.

Great post! I don't understand how people continue to describe the universe as an ordered phenomena that must have been created. If galaxies colliding suggests an ordered universe, what exactly does a disordered universe entail?

Thanks alpha,

I do understand why people continue to describe the universe as an ordered phenomena that must have been created. Because they do not understand the things of the universe, and saying "god did it" is easier than researching and seeking real answers and understanding. Also, saying that there is some kind of order to things makes humans feel less vulnerable than they actually are...we are basically "sitting ducks" in the whole chaos of the cosmos.

If our universe will collide in 3 billion years and our sun will last 10 billion years and the time frame of us getting hit by an asteroid is getting smaller and the chance of Yellowstone exploding gets nearer, life on this planet will end.
Who will god have to pray to him then?
