I'm absolutely obsessed with the universe and it's greatness. Here's a couple videos that amaze me.
This first video is a deep zoom inside the andromeda galaxy - This is the closest galaxy to our own Milky Way. The video shows a black hole with young blue stars swirling around it. It amazes me how the strong forces of the black hole don't suck up the stars or rip them apart.

This video is a simulation of the Milky Way Galaxy and Andromeda actually colliding. The collision is calculated to happen in 3 billion years. I have no idea where humanity will be by then but the sun will be extremely hot. The earth may already be cooked by then. Humans may be so advanced that we could relocate to another galaxy! Just think 3 billion more years of evolving.

This video shows you examples of how large stars can actually get. The Earth is a little pebble compared to our huge sun. Our sun is very very big. But wait until you see these other stars compared to our sun(sol). You'll be amazed. Take a moment to pause parts of this video so you can observe the examples better.
