If the particle horizon is already vast enough beyond our capabilities, imagine if there is another civilisation far away (beyond our horizons) and they have another particle horizon and they assume that that is the universe while we assume our particle horizon to be the entire universe... 🫥 How huge would the entire universe be now?? 😭

It's definitely how infinitely vast I think everything is and it's both terrifying and fantastic. Someone else commented by saying they find it comforting and I really do. I don't know if these other forms of life would be like us or completely different, or even "good" (whatever that would mean in their world) but it's still so incredible. Though I'm also glad I don't get to ever know that, because there can be neutral, good and bad surprises haha.

All the awe in astrophysics also applies to nano physics. As above, so below. 🤯
