Our Universe

Actually...

If those stars are so much bigger than the sun, and they're in our galaxy as well, how come we can't ever see them?

The closest star to Earth apart from the sun is Alpha Centauri, which is located 4.37 light years away from us. It is a bit larger than our Sun. Alpha Centauri is in fact visible on a night sky as a dot. The hyper-giants that you see in the video are also visible on a night sky as a dot that is the same size as Alpha Centauri's. However, many of those hyper-giants are as far as 3000 light years away from us. So think about that... we are so fay away from these monster, that they still look like dots in our night sky regardless of their size.
