OctPoWriMo 1 - What is Time?

Today is the first day of OctPoWriMo 2016. The prompt today is "time." A couple of days ago, I found this article about the physics of time, and thought it was a fascinating look at how science views time. What does "now" really mean? It's an ephemeral concept that is constantly changing. While I write this, "now" is a different time than the "now" when you read this, yet they are both "now."

I decided to use the form Minute Poem today, since it's crafted to be a reflection of the measurement of time, so I figured it's appropriate. With 60 syllables, it's meant to take about a minute of time to read. Though, of course, I'm a super fast reader, so it takes me around 30 seconds to read it. And it took a lot more than a minute to write.

What is Time?

To say you live within the now—
Well, really, how?
When, oh, so fast
It is the past.

What is time? Can we explain?
Can human brains
E’er apprehend
And comprehend?

Always moving, never still;
I swear I will
Take time for rest
To ease the stress.
