This morning I watched a video that explained that to get to the next galaxy, the Andromeda galaxy, it would take 2.5 million years travelling at the speed of light. Imagine that, travelling 300,000km per second for millions of years. And then you’ve only reached the first of trillions of galaxies… Not billions, but trillions of galaxies in our universe.

It’s so hard to make sense of these numbers. I understand what they mean, but I can’t really comprehend the scale. For example, let’s break down the idea of traveling 300,000km in a second. That means travelling 18 million kilometres in a minute, or 1,080 million kilometres in an hour, or 1 billion & 920 million kilometres in one day.

And at that speed it would still take 2.5 million years to get to the next galaxy.

I understand what the numbers mean, I just struggle to fathom the scale in a way my brain can grasp beyond saying, ‘That’s really far,’ and ‘The universe is really, really big.’ No matter how much I cognitively try to grasp how ‘really big’ our universe is, I know that in reality it’s magnitudes bigger than I can comprehend. This is truly mind boggling.
