The universe is around 13.5 to 14 billion years old. That means that if everything started from one singularity which was the big bang, and nothing can travel faster than the speed of light, the size of the universe must be at most 14 billion light years in size. But even that is an extremely large overestimation since most things don't even go near the speed of light. The sun for example, orbits the milky way, at 150 miles per second, the speed of light is 186,282 miles per second. That's more than 1000 times slower than the speed of light. So given these calculations, either objects can travel faster than the speed of light, or the universe is tiny. but there are 10 billion galaxies, each with 100 billion stars out there, and they're not close together at all. The closest star to the solar system is 4 light years away. If that is the average distance between stars, and we're not even going to calculate the average distance between galaxies, how can so many stars and galaxies fit in so small a space. I'm no scientist so I'm sure I'm sure I've misunderstood some of the concepts of physics, but something here doesn't seem to make sense.
