According to this computer model , the universe was filled with irregular looking objects like the ones shown above. The simulation then predicts that these blobs of stars and gas collide to form galaxies more similar to the ones we see today. In fact, this simulation bears much resemblance to recent pictures of distant galaxies taken by the Hubble Space Telescope . Galaxy formation is a complex phenomena which only now is becoming understood. Simulations like this one are helping to determine the answer.
