The best way to think of the universe is like a book, a really big book. The first page is the big bang and the last page is so far away we can't see what it looks like yet. The universe is everything in the book including us. It's not just the "things" that are described such as planets, galaxies, people, empty space etc. It's also the events described. Me writing this post at this time on this phone is now an event, and this "event" is now part of the universe. Every thing, every place, every event has universal Coordinates of location and time. Belfast, Ireland at 13.41 on Sunday 6th January 2019, immortal J posts on little biggy about the nature of the universe. In this sense you could say that we are creating our own universe as we go. If an alien being that exists outside of our concepts of space and time could read our book, he could go to this page, this line and see me writing this post. There could be a whole load of shit outside the book but we don't know, because we only exist within it. We can never see the front cover or the back cover. We are limited to what happens in the pages. This is our reality. The whole entire universe is just our concept of reality. We cannot even comprehend what might exist outside the front and back cover of our book.

ImmortalJ is spot on!

I like to think of the universe or space as a gigantic ocean. Our little earth is just a mere island in space, and all those other galaxies and planets are islands in our endless ocean. Imagine if you were one of the first members of the human race who was born on one of the thousands of islands that make up Singapore. You may be able to see other islands from your island but until the invention of boats and ships you can only dream of what those islands would be like. Space and the universe is just like that but on a higher level. Our Earth is one of those tiny islands and now that NASA is planning to build a moon base, you could say we're taking our first steps towards space travel. We live in exciting times. I wonder what Galileo would think if he were alive today. Stoned astronomy with him would be awesome. Ok, now I'm rambling...
