Here are a few videos from Youtube about how big the universe is. It is difficult to comprehend how big it is. In these videos the distance increases x10 each time. This means that it zooms of from 1km, to the next frame to 10km, then 100km etc. So, each time the ‘camera’ moves out the distance is much greater. I hope you enjoy them, I know I did. Let me know if you have any questions or you have any comments.
