Ok, so I am going way off topic with this post but i’m a sucker for any program on physics and space (looking at you Brian Cox and Jim Al Khalili), or nature (David Attenborough). Being able to explore a galaxy is likely why I had a brief (couple of years) foray into EVE online (cool ships and shooting aside!).
Why am I mentioning this (bar to give you info about me you probably don’t care about ;p), it’s because I found this video about a detailed map of our Universe and how galaxies make up superclusters. I have no idea of the validity or accuracy of the info but I love this stuff and had to share it.
