I read an interesting way to try and grasp the size of the universe. There are 250 billion stars in the Milky Way, plus or minus 150 billion. Every 100 years or so there is a supernova event in it. It releases a distinctive burst of radio waves which we can detect. These bursts are detected at the rate of one a second coming from all the other galaxies in the universe. So, count up how many seconds there are in 100 years, and it gives the size of the universe in galaxies..I thinks it’s simply numbers (vast numbers of stars we can’t even get our minds around) and simple probability.
