Elusive Present Caught Between Past and Future
Have you ever tried to pin down the present?
Can’t do it, can you? Neither can I, but it’s not for lack of trying.
Stuff that’s about to happen comes at us from the future. Stuff that’s already happened recedes into the past. But, what about the present? You know . . . the stuff that’s happening right now? Uhhh . . . now! I mean . . . now! Okay . . . now! Oh, all right . . . now! Dammit . . . now!
Elusive little bugger, the present.
You still don’t get it, do you? The present doesn’t exist, except in the abstract. There’s only stuff that’s about to happen, and stuff that’s already happened.
Let’s look at this another way. Think of the present as being a moveable interface separating the past from the future. It travels at the speed of time along a timeline that extends from the beginning of time to the end of time. No matter how small you make the time interval that separates the past from the future, no matter how narrow you make the window that defines the boundaries of that illusive and elusive thing you call the present, you can never achieve the present.
Think of the present as being to time as a point is to space. It’s a reference point, a marker that has no bulk, no mass, no weight, and no dimensions.
Does time travel exist? Sure, it does. We’re all time travelers. But, so far, we’re only able to travel in one direction in time—into the future. Unfortunately, our limited time travel is further limited by the speed of time, itself.
We know that the speed of light is 186,282 miles per second, but how fast does time travel? The easy answer is one day, one hour, one minute, one second, one millisecond at a time. A more complicated answer is that it’s relative depending on your own speed in relation to the speed of light, and on your own position in the universe in relation to the clock.
But don’t take my word for it. I’m not Albert Einstein, or Stephen Hawking, or even Herbert George Wells. I’m just someone who’s messing with your mind.
The past! (We can visit it in our memories or in our history books.)
The future! (We can visit it in our imaginations or in our science fiction books.)
That’s all there is. There is no present.
Well, maybe, on your birthday . . .!

Time flies when you're old enough to see the obvious.
As you’ve gotten older you probably noticed that time seems to be picking up speed, as if it were trying to leave you in the dust. Do you ever stop to think that maybe it’s just you trying to return to the dust?
Admit it! Things aren’t like they were when you were a kid. Back in the day there was time enough for everything. Those were the days when the hardest things you did were to learn to do the things you now take for granted; tie your shoes, tell time, read and write, the multiplication tables, stuff like that.
Back in the day, time slowed to a crawl as you fidgeted your way through the school day, hurried out to play, then struggled to get your homework done in time to watch an hour of television before your nine o’clock bedtime. The school year seemed to last forever, but when summer vacation finally came, it lasted long enough that by the time the new school year started, the previous year was only a distant memory.
Those were the days when you didn’t have to stop to smell the roses. You could smell them as you pedaled by on your bicycle, just as easily as you could smell the dog shit squished between your toes as you raced, barefooted, across the yard, or the aroma of fresh-baked cookies wafting from the open kitchen window as you played catch with a friend. You didn’t have to stop to do anything. Only rarely did you even slow down.
Whatever happened to those good old days, anyway? Today, it seems as if your plate is always full. Too full. You plod along, knowing that whatever remains on your plate from today gets added to your plate for tomorrow, ensuring that you won’t finish tomorrow’s tasks, either. The backlog builds; the days grow shorter.
The sun comes up, you blink a few times, go through a few motions, and then the sun goes down. There never seems to be enough time, in one day, to do all the things you have to do. But, there’s always tomorrow.
Few people who have entered into middle age will argue the point; most people agree that as they age, time seems to speed up. One day blurs into the next and pretty soon another year is gone.
I think Einstein’s theory of relativity adequately explains this time distortion phenomenon. I’m pretty sure that in there somewhere he postulated that time slows down as one moves faster through space.
The answer is simple, then. Kids move faster than aging adults do, so time goes by slower. Aging adults are slower than kids are, so time goes by in a rush.
It’s all relative.
