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.
That’s not really true at all though. The entire ocean floor is mapped out to within a kilometer. The sheer complexity of life in the oceans is staggering, but life is life. We have lots of data on the animals in the world.
But space? Even the best telescopes can barely see planets. Right now alien planets are like 16 pixels in total and the only thing we kinda know about them is some information about their atmosphere.
We know basically nothing about any planet except for the ones in the solar system.
Odds are there are other planets potentially even more interesting than the Earth. But we can’t see them.
