I don't like contemplating oblivion, so I did the opposite.
I wondered for a while whilst in class if the universe was really as big as we thought it was. What if it was a bubble, a skybox that we can somehow dive into with telescopes? What if we're constrained to our one little galaxy, and there's nothing out there? What if this world is really as small compared to the rest of the universe as we think it is but there's nothing else like it? I felt small, I felt constrained. Then I looked out at the beautifully well cared for grounds that our school has, and remembered that I love walking the length of them, something that usually takes me about ten minutes. I remember when I humped the boonies for a week around the Grampians, and how beautiful they were and how small they were compared to the rest of this equally beautiful country. I remember how I climbed Mount Maunganui that one time when I was on holiday and it was a perfect, cloudless day and how that took an hour and was beautiful and how small the Mount was compared to New Zealand, a small country itself. I realized that even if this world was all there is, it's amazing one hundred, one thousand fold and I'm never going to see all of it. This could well be all there is, and it will be all there is for me unless we miraculously find other planets to live on that we can travel to in less than a decade in the next 100 years.
And for me, that's enough.
And then I realized that I was rambling in my head and wasn't making much sense and then I think someone flicked something at my ear and it was at that moment that I decided to make this post about something that started sad and then made me happy because there's too much sadness in this thread. So now you know.
