Time Travel

Day 92 – June 16, 2020

A little after 10am on the morning of December 17ᵗʰ, 1903, upon Kill Devil Hills in Kitty Hawk, North Carolina, Wilburn and Orville Wright flipped a coin. Orville won the toss, thus putting him in the historical category reserved for people like Neil Armstrong. Wilbur was the Buzz Aldrin of this metaphor. It’s incredible to think that it was only 66 years between that first powered flight that morning (4 flights that day, Orville and Wilbur alternating turns at the controls), and walking on the moon.

The Wright Brothers had built their flyer in Dayton, Ohio, and secretly moved it to the coast in October, where they rebuilt it and tinkered with it until it was ready. What’s interesting, and what, to me, is perhaps an even better argument against the possibility of time travel (at some point, I wrote about how’d you materialize in the middle of outer space because the earth will have moved — a lot — even if you only travel a tiny fraction of a second), is that when they flew that day, there were only 5 other witnesses. If time travel were possible, what a “time-tourist-destination” that would be. Kill Devil Hills would be covered with millions of people hoping to see this with their own eyes. I’d be one of them.

Indeed, if you were given a time machine, but you could only use it once… go somewhere in time, and then come back today… would you go backwards, as per above… or forward, to see that the future looks like?

To me, it’s a no-brainer… I can read about the past from many different points of view and build some understanding. But the future? Like how incredible would it be to see where things are at in 1,000 years? I’d be all over that. Which brings us to a great word of the day…

Ellipsism: (noun) A sadness that you’ll never be able to know how history will turn out.

I think that’s what I felt this morning reading a very interesting article in The Astrophysical Journal, which talks about another interesting “way-out-there” scientific topic: Life on other planets.

These guys did a lot of fancy math, based on some well-thought-out premises and assumptions, and came up with the number of civilizations in our Milky Way Galaxy capable of interstellar communication. That number turns out to be… 36. Plus 175 or minus 32… so, for sure, somewhere between 4 and 207. And take that “for sure” pretty lightly, because, at the end of the day, who the hell knows.

But man, would I love to know. As far as we know today, there’s almost certainly intelligent life out there. But what we also know, warp drives and other cool science-fiction technology notwithstanding, is that given the fabric of the universe, we may never know. Albert Einstein came up with some theories more than 100 years ago, and no one has managed to prove him wrong. Nobody is exceeding the speed of light anytime soon (ie, ever), so, at best, maybe a few radio communications… and we’ve been sending messages out, on purpose or not, for maybe 100 years. We’ve been listening too, but haven’t really heard much — with a few curious exceptions over the decades… unexplained, but not proof of anything. The best case scenario would be finding intelligent life 4.4 light years away, at our nearest star system (Alpha Centauri, made up of three stars and a bunch of planets). Many people have been listening in that direction, but we’ve heard nothing of interest.

It’s frustrating, because that’d the best case scenario, but it would still take almost a decade for a quick back and forth. And what would that even look like…

Us, in 2020: “Hello, hello, is there anybody out there….”

Aliens, in 2024: “⍝⌷⌿⍝⌵⍰⌼⌹⍊⍠⍏⍛⍘⍙⍎⍜⍁⍚⍎”

Us, 2029: “YES, HELLO!! WE ARE HUMANS ON EARTH!! WHAT’S UP!!”

Us, 2037: (sigh)

And of course, the relevant and expected closing to an essay like this… how can we be searching for intelligent life out there when it’s already so difficult to find around here, ha ha. It’s interesting to think about, how on some alien planet a zillion miles away, aside from the scientific alien-searching intelligent brainy aliens, there are also stupid aliens. Conspiracy-theory-believing aliens. Aliens who won’t wear their version of a mask when out in public, during their alien pandemic. Yeah, that’s a zillion miles away. Much closer to home, 5,000 miles away, is Paris, France… where today, if the video I saw this morning is to be believed, things are “back to normal”. Crowded city streets, crowded cafés. I would’ve thought the video was from last Summer, except for the waiter wearing a mask. I am the first to say, I hope I’m wrong. I hope this doesn’t turn into a complete disaster. Paris had its worst of this in early April, and things look a lot better… but numbers are still going up, and we’ve already seen many examples where the “rush back to normal” is causing problems, so much so that lockdowns might have to happen again. In B.C., unlike many other places, slow and steady is winning the race. But with my daily dash of ellipsism, I really wish I knew how this is going to turn out.

Day 74 – May 29, 2020

If you’re a flat-earther… stop reading now. But if you actually believe the earth is a sphere (it’s actually an oblate spheroid, a little flatter at the poles and bulging at the equator, because of the spin… but whatever…), then you may have wondered at some point… how fast am I moving? If you’re standing at the South Pole, the answer is… you’re not… you’re just spinning in a very slow circle, completing a full revolution once a day. The circumference at the equator is 40,000km, and a day lasts 24 hours, so the math is simple — you’re whizzing along at 1,667 km/h… a little over 1,000 MPH. Actually, you’re moving through space a lot faster than that… because the earth moves around the sun, and our solar system spins around the center of our galaxy… and our galaxy itself is also moving through space, at over 2 million km/h. There’s no better proof of the impossibility of time travel than that… even if you move back in time one second, you’d materialize in the middle of nowhere, out in space somewhere. OK, that was a tangent… where was I…

The city of San José, Costa Rica, is a little over 1,000km north of the equator, somewhere around the 10-11º latitude. What’s interesting about places close to the equator is how quickly the sun rises and sun sets. Given how fast the earth is moving at that spot, it makes sense. It goes from full sunshine to pitch black in less than 30 minutes, and same with sunrise, but the other way around. And how little sunrise/sunset times change throughout the year. Without exception, no matter what time of the year it is, somewhere between 5am and 6am, pitch black to brilliant sunshine. And sometime between 5pm and 6pm, the opposite. Every day lasts almost exactly 12 hours. They have no idea what it’s like around here, for it to be pitch black at 4:30pm on those miserable Winter days, or brilliant sunshine after 9pm (coming in less than a month!)

What’s also interesting about San José is the temperature variation throughout the year — or lack thereof. There are no hot or cold seasons… it’s all the same, year-round, and the temperature range is a narrow sliver. Over a typical year, the coldest temperature is around 18ºC (64ºF) and the hottest is around 27ºC (80ºF). That’s only a 9ºC difference, and if that’s all you’ve ever known, the temperatures near the edge of that range can feel extreme… which leads to the amusing situation some friends and I found ourselves in when we were there. We were staying in a nice place with a beautiful pool… and it was after dinner, already dark, but it was 18ºC out… more than suitable pool weather. So we’re in the pool, splashing around, having a great time… and there’s a security guard wandering around… in a full winter jacket, toque, gloves and ear-muffs. Looking at us like we’re crazy. And we’re looking at him like he’s crazy.

But that’s all he knows, and that’s all he’s used to, and 18ºC to him is like -20ºC to us… the very edge of super-cold.

And now you’re wondering what this might have to do with this pandemic (I was going to say “global pandemic”, but every time I do, my son corrects me… “As opposed to what, dad… a neighbourhood pandemic?” — OK, it’s a pandemic… it’s global. And it’s very straightforward… it’s making us look at things differently, for us — but things that for certain people are a way of life, because they were already used to it.

Indeed, I think for a lot of people, adjusting to the new-normal has been a bigger shock, the more complicated their previous life was. Because really, the simpler your life was before, the easier (if any) adjustments you had to make. Some remote village where people live self-sufficiently, grow their own food, fish, raise chickens… they’re barely, if at all, affected. There’s that lingering thought I keep having about simplifying life in general, because now that things are starting to open up, my old life is pulling me back in, and I find myself resisting a bit.

We’re still far from the end of this, and we’re all itching to bring back at least some degree of familiar normalcy. It’ll be a far cry from the real thing, which is coming one day… on the (hopefully not too) distant horizon… but even when things are 100% back to normal, I hope we can hold on to some of the not-so-normal, that was imposed upon us… because it’s not all bad. I certainly hope so. I’m trying.

When I told some guy in Costa Rica that it sometimes doesn’t get dark until after 9pm here, he was startled… and he asked, “What do you do?”. What an interesting question… what do you do with all that extra daylight. Well, the answer, I suppose, is you make the best of it. Much like we’ve all been making “the best of it”. But hopefully we’ve learned something that carries through; something that was very new to us, but blatantly obvious to someone else, someone from whose life we had something to learn, even if we didn’t know it before.
