Did you know that if the universe had expanded just a little faster after Big Bang, then the matter in it would have been scattered and spread out across the universe, lost in a way that would have precluded the formation of both galaxies and stars. Or if they had flown apart slightly slowly, all the matter would have clumped together before the star systems had a chance to form,. This is just one example of the universeâÂÂs fine-tuning. See how modern astronomy reveals the signs of God.
