After my last post on Composing an effective blog post title, you’re probably scratching your head wondering what on earth this post is going to be about. Well, it’s just a trip into fantasyland. I’ve wanted to get this one off my chest for a while so here goes. If it’s not quite your cup of tea, please have a look at the recent posts listed in the right column instead.
We all daydream. When I was a kid, I remember thinking about these two wacky ideas. Perhaps you have too.
A universe on a grain of sand
If any of you have see the movie, How the Grinch Stole Christmas, you may remember the opening sequence focusing in on a snowflake and the fantasy world on it. It reminded me of my childhood daydream. Is it possible that there could be a universe on a grain of sand? We all have some concept of really small and very large. Naturally, we compare things to our own size and everything is relative to that – bigger or smaller. An atom is so small we can’t see it and the universe is so huge we find it hard to imagine its size too, but is that just because we’re viewing things from our own size perspective? What if we viewed things from the perspective of the infinitesimally small, is there any reason why this different concept of size couldn’t present a universe on an atom or a grain of sand?
This guys barking mad I hear you mutter. Well, I came across a website recently which MakeUseOf blogged about – The Scale of the Universe. Nice site looking at the scale of things from the ‘string’ to the Universe, but in the comments were some thoughts similar to my own:
And when you look outward from our perspective of scale, is our own universe just one of an infinite number of universes perhaps on a grain of sand… in another universe?
A billion years in a microsecond
Funnily enough, my childhood daydream about scale went on to ponder about time. Just like size, we think about time from our own perspective. We know that a second is pretty short and a century is longer than most of us will live for. But does everything share this perspective of time? Is it possible time could move at a different ‘pace’?
Putting these two thoughts on space and time together, is it possible that the universe on the grain of sand could experience a life of billions of their years in a fraction of one of our seconds?
Okay, this piece may be a little wacky and perhaps not argued particularly well from a scientific point of view, but it’s thought provoking nonetheless. Most probably, it’s all nonsense and certainly most religious teaching would quickly dismiss it out of hand.
But if you’re interested in hearing some more thoughts about the vastness of it all, have a listen to a great podcast on Radiolabs – The (Multi) Universe(s). Are there an infinite number universes out there?
I’d love to hear your thoughts on this.
Normal service resumed next week… maybe!
