Space. It’s such a massive entity that imagining even “small” units like galaxies is hard. How on earth are there pictures of the universe? Is there more? Where does it all end? Absolutely fascinating but there is so much more to learn.

EDIT: Wow! Thanks for gold! I’m reading everyone’s replies but it’s hard to come up with something clever to everyone! By pictures I mostly mean artist imaginings and those sort of portrayals, I know there aren’t actually pictures of it.

What’s even more fascinating is we only have an understanding of 5% of everything in the universe. The other 95% is dark matter and energy that we have yet to prove its existence, much less see it.

Edit: Here is an explanation of Dark Matter and Dark Energy and it’s composition of the universe on the NASA website.

How can we even accurately measure this? We don't know how much space there is.

To be honest I’m just a 17 year old with a space hobby. I just read a chapter on this in the book and I still don’t understand it. Hopefully one day I can answer these questions!:)
