We will never have time travel

I’m not a physicist and I don’t play one on the internet, but I believe that we will never have time travel. My premise is simple: if it was invented 50, 250, 500, or even 5,000 years from now, there is no way that the first time we’d ever discover someone from the future was 2022. Surely if it will ever be invented a time traveller would travel to somewhere in the past before us, and we don’t have evidence of that… so at no time in the future will a time machine be invented.

The only possibility that I see for a time machine to work is that we live in a multiverse and if a person did go back in time then they wouldn’t change our history, they would create another new history splitting the history we know and creating a new one that they know… and so in this case while I’d be wrong, you and I will never know.

In the future, if we don’t blow ourselves up and send the world back into the Stone Age, we’ll get closer and closer to traveling the speed of light. A very long time from now humans will visit other planets beyond our solar system. Those travellers will experience time differently than anyone who stays on earth. But while they will age less, they won’t be going back in time.

Time travel like H. G. Wells wrote about will never exist. It’s a fun thing to think about, but the reality is that if it ever was to be invented, we’d already know about it… we wouldn’t have to wait for some time in the future to learn about it.

Time dilation

Yesterday I experienced a bit of a time warp. My morning went a bit slow, both in my productivity and in how long it felt. After lunch it felt like everything was thrown my way, and I was constantly on my ‘to do’ list, which seemed to be filled with things that took longer than they should.

At one point a package arrived, and I thought I’d take a break and take it to the teacher who ordered it. When I passed my grade 9 classroom it was empty, and I wondered where they were? As I learned, they had left for home. I thought it was about 2:30 in the afternoon and it was actually 3:50. It was almost an hour and a half later than I thought!

I’m always amazed by experiences like this. How can one hour of busy work or fun disappear, and another hour of slow work or boredom feel like an eternity? Just like actual time dilation is about time being different based on relative velocity, it seems as though we can experience this based on the velocity of our thoughts relative to actual time.

I also wonder about how relative time is based on our age. Five years is half of a lifetime to a 10 year old, but just 1/11th of a lifetime for me. Does my perception of time change with age? Does the importance of events alter because of the relative time of the experience compared to how many more experiences the event is compared to?

And what makes a single day feel both short and long at the same time? It’s early April, and I already know that the school year will be ending before I realize it. I’ll be swept up in all the things that are coming up, like report cards and grad prep, and suddenly I’ll be saying goodbye to a whole group of students. On that journey I’ll have long and short days, but looking back at the end of June, I’ll think the days from now until then just breezed by.

It’s not just a day in time that dilates, but weeks, months, and years too. It just seems strange… We want to fill our time with activities and events that are enjoyable and thus tend to go by faster. So, we are literally speeding up our lives. But the alternative is to spend a perceptually longer life that is less busy and enjoyable. Is one of the goals of life to have it feel like it’s going too fast? Or is this just an outcome of a good life?

One cation I think this brings attention to is that if time is going to race by, we should at least do our best to make it joyful and not just busy. Because time can also race by when we are just busy, but to what end?

Ripples over time

Facebook reminded me that I just recently passed 14 years since moving from teaching to administration. My FB memory led me to reread this post, Ripples and Tidal Waves, which I wrote 2 weeks after my promotion. I had so many things that came together at that time, which led to me being a presenter at Alan November’s conference a couple years running. I was even toying with the idea to go and work for Alan. How different my life would be now if that was a wave I chose to ride!

Looking back to that point, I had no idea what was in store for me. Living in China for 2 years? Not even a consideration back then, but I did just that a year and a half later. Co-founding a public, inquiry based school? Not on the radar. The only thing I can say that was expected is that I’d still be blogging all these years later.

We never know how circumstances and decisions will end up rippling and leading us to different opportunities and challenges, but we are fortunate when we can look back to a point in our careers 14 years ago and think, “This has been a great journey I’ve been on!” From here, I have less than 1/2 this time until I retire, and so I’m left wondering what ripples lie before me? Retirement for me will not mean gardening or golfing, and I can’t sit still for too long, so in the next few years I need to look for the ripples that come my way… or I need to make them.

Tiny little moments

Some days slip bye and when you look back, it’s hard to say what you did to fill them. On those days I try to think of small yet special moments:

A laugh with colleagues.

A good conversation.

A delicious snack.

A kind gesture.

A selfish moment.

A selfless moment.

A single accomplishment.

It doesn’t have to be a big thing, it just has to be something that I can identify that made the day a good day.

When you read quotes about life, you read things like, “Life isn’t measured by the breaths we take but by the moments that take our breath away.” That sounds beautiful, but how many daily ‘take your breath away’ moments do you really live in your daily life?

No, life’s not just about the breathtakingly special moments… it’s about filling you life with, and appreciating, the tiny little moments that make life worth living.

Fast and slow

We are having a renovation done and it’s about to move a lot faster. When electrical and plumbing are happening, the changes are incrementally slow, but this week they will start the drywall, and then things will start to move really quickly, adding walls, cabinets, and flooring. Soon we won’t remember what things look like now.

Kids are the same. Day to day you don’t notice them growing up, then suddenly they are adults. Day to day they are just your kids, but blink and suddenly they are their own people, with their own relationships, and work. The transition was slow, but looking back it seems so fast.

When you are building a home, things move both fast and slow.

Time warp

Have a look at this infographic:

Dinosaurs ruled the earth for 135 million years, and disappeared in a mass extinction event 65 million years ago. Early hominids, the ancestors of early man only showed up 10 million years ago. If you were to draw a timeline from the first dinosaur to today, then the last surviving dinosaurs are closer in time to humans than they are to the first dinosaurs.

I don’t know why I grew up assuming that humans and dinosaurs co-existed long ago, but give me a break… I was only 55-60 million years off! Maybe it was drawings of humans and wooly mammoths? Maybe it was cartoons? But it’s a real time warp when you think about how long dinosaurs ruled the earth, and how short of a time humans have existed.

It’s even weirder to think of the time it took from the first steam engine to the time when our industrial lives started to threaten the well-being of our planet. Is this what intelligence life forms do? We’ve just been looking at time in millions of years, but the first steam engine was built just over 400 years ago.

Humans have been on this planet for such a short time, yet we place so much attention on ourselves and our significance, as conscious beings. This one species, on an insignificant planet, in an insignificant solar system, in an insignificant galaxy, at an insignificant time in the existence of the universe.

It’s time we got over ourselves.

Junk vs treasure

As we pack up our main floor for our renovation, I’m coming across souvenirs and trinkets from vacations and travels. Some of them have been hidden in drawers and cabinets unseen for years. Do we keep it or throw it away? Does it get put in a box only to be seen again when we unpack after the renovation, and then tuck it in a drawer not to be seen again until we move? Or do we let go of it now?

The saying goes ‘One man’s junk is another man’s treasure’ but when looking at your own stuff, sometimes it is simultaneously both. Do we need 3 sizes of wine glass sets for more than 6 people each? Do we also need the fun set of patterned wine glasses, and the plastic ones for outside? No, we don’t need them. But will we throw or give any away, or will we keep them? Are they worth holding on to?

I suspect we will be keeping a lot more junk than we should. We’ll see value, be it functional or sentimental, and we’ll hold on to too much stuff. I think we would get rid of a lot more items if we had a critical friend helping us and just asking, “Do you really need to keep that?” In most cases the answer would or should be ‘No’, but for my wife and I, many of these things will end up in a box and back into a drawer or cabinet. Hopefully we’ll be a bit more hesitant to keep some of our boxed junk when it’s time to unpack, and these unnecessary items will be given away to find homes in someone else’s house.

But I’m sure of one thing, we are going to end up keeping far more than we should… Maybe not truly a treasure, but not quite considered junk (yet).

Internal clock

When I go to bed, I can set an alarm and the tell myself to wake up before it goes off. I’ll wake up before the alarm goes at an average better than 9 times out of 10. It doesn’t work when I’m napping. It does t work if I’ve had a few drinks. But on a typical morning, I’ll wake up anywhere from 20 minutes to 2 minutes before my alarm.

However, if I wake up and check the time an hour or more before my alarm, what I can’t do is change the time I plan to wake up. It’s like the original time is locked in, and in a half-sleeping state, I lose the ability to change that time.

This morning I woke up an hour and 25 minutes before my alarm and decided, I’ll get up 30 minutes earlier. Closed my eyes and even dreamt about waking up earlier. Then my eyes popped open 2 minutes before the original time I had planned to get up, allowing me to shut off my alarm before my wife had to hear it. No extra 30 minutes for me this morning.

Despite my inability to change the set time during the night, I’m always puzzled and amazed at how I’m able set my internal clock before going to sleep. How does my body/mind know what time it is? If I woke up at exactly the same time every day, I think this would be more understandable. But I vary my wake up time by over an hour on weekdays and wake up another hour plus later on weekends. And I haven’t heard my alarm in over 2 weeks.

With respect to how we’ve evolved, the inventions clocks is such a new novelty, that there is no way it was a necessarily learned behaviour. Being sensitive to light outside our eyelids is a natural cue to let us know it’s time to get up. But the difference between waking up at 4:45 and 5:30, in total darkness, isn’t something our bodies should just know and be able to do.

How does our body know the difference? How are we able to control an internal clock? And how do we keep track of this while we are asleep, unconscious?

We live in a time warp

When you are 10, 5 years is half a lifetime. 10 years is half your life at 20, and 20 years is half your life at 40.

By the time you hit 40, your first 20 years are a distant memory, and you remember choice moments, but you don’t remember those years like when you were younger. The distance in time causes you to lose your ability to hold on to old memories. You can’t hold an ever accumulating amount of memories, and so some fade away. So time stretches the past into a distance too far to see everything.

Meanwhile, 1 year at 10 used to be 1/10 of your life. A year at 20 is 1/20th of your life and a year at 40 is 1/40th of your life. Each year, the lengths of a year as compared to the rest of your life diminishes. So time also shrinks the future while it stretches the past. We live in a time warp, and time goes by faster every day.

Sometimes it’s good to reflect on this, if only just to appreciate the fleeting moments in a day, and know that unless we appreciate the time we have, we can only appreciate the memories that we know will fade away.

Time keeps ticking

It’s wonderful when you get to spend a weekend with family. I enjoy my work, but I have to say that I’d love a 4-day week with 3-day weekends. Time seems to be going by so quickly.

As I get older, I seem to be more and more fascinated by time… and the time we have with our family of different generations.

Here is a video to help you really think about this.
