Observing time

Leave a reply

Yesterday’s post, ‘Let’s Do the Time Warp Again’ is still messing with my head a bit. The idea of the Andromeda paradox suggests that if we are in motion compared to another bystander, our view of very distant events can be days apart.

I understood relativity with respect to travel, a twin in a spaceship travelling close to the speed of light goes to a distant galaxy. When he comes back to earth a few years later he would be younger than the twin left behind… demonstrating the relativity of time. But the idea that distant events can ‘happen’ at different times for people witnessing it from almost the same spot, simply because of their relative motion to each other is perplexing.

So then I suggested that we could re-witness an event by changing our motion such that we are moving quickly away from a very, very distant event, so that from that relative perspective the event hadn’t happened yet. I’m no physicist, the distances would have to be huge, and I don’t know what speeds would need to be achieved, but it seems pretty conceivable to me.

What’s messing with my head is that if this is possible, what does ‘now’ mean?

We have to wait 8 minutes for the sun’s light to reach us. When it reaches us, the sun is already 8 minutes older. We don’t see the sun now, we see its history. Our concept of now has a perpetual lag.

This then got me thinking about animals and their reaction times. Have you ever seen a video of a cat toying with a snake? A cat can avoid the bite of a snake, always reacting faster than we would be able to. How does a cat perceive ‘now’ differently than us?

How do birds fly in a murmuration? The flock changes direction in waves, so quickly that they can stay in formation despite hundreds of them having to coordinate with each other. How does a bird in a murmur perceive ‘now’ differently than us?

To a ten year old, 5 years is half a lifetime, to me it’s less than 1/11th of my life. Is it any wonder that as we get older, time seems to go by faster?

Like I said, these ideas are messing a bit with my head. They make me wonder what ‘now’ means and if in reality we share a ‘now’ with anyone? Is the mere act of observing ‘now’ just a relative glance of varying histories? And yet the only thing any of us ever experience beyond our memories and imagination… is now.

Let’s Do the Time Warp Again

“It’s just a jump to the left… it’s a jump to the ri-ight🎵”

…And that’s all it takes to witness two completely different views of what ‘right now’ means:

“The Andromeda paradox, proposed by physicist Roger Penrose, is a thought experiment in relativity that highlights how simultaneity depends on an observer’s motion. It imagines two people walking past each other on Earth: one toward the Andromeda galaxy and one away. Because of special relativity, the plane of simultaneity for each observer tilts slightly, meaning that the events they consider “happening right now” in Andromeda could differ by entire days. This illustrates that what is considered the present in distant regions of space is relative to an observer’s motion.” (ChatGPT)

Here is my thought experiment based on the Andromeda paradox:

If we were to witness a supernova of a star hundreds of light years away, could we send a rocket hurling at a high speed away from that event and capture the event happening again? Could we re-witness the supernova, a past event that happened many years ago, but from farther away? Would it be possible that from that perspective the event has not been witnessed yet, and so we can ‘get ahead of it’ focus our cameras on it, and wait for it to happen again, just for the first time from that relative perspective?

My head hurts a bit trying to make sense of this, but my hunch is that it would be possible. So instead of the Andromeda paradox, it’s more like the Andromeda mirror, bouncing back the same light but at a slightly later time than the present… which already is what a mirror does. 

Lacking decorum

Leave a reply

I used to think, ‘I don’t understand how we got here?’ But I’m beginning to see a pattern.

Honour, respect, and decency are conventions. They are merely expectations, they are simply the way things are normally done in a caring culture. Decorum is upheld not by the roles of everyone, rather it is upheld by the usual lack of tolerance for people that don’t show decency. A key role for those with power and influence in a decent society is to demonstrate what’s acceptable, and when they don’t, conventions are not enough.

Conventions, decency , and decorum are expectations, not laws. To break them is not illegal, but rather just ugly. And sad.

Our collective tolerance has been too weak. The ‘paradox of intolerance’ is the problem on two fronts. First, in being too tolerant of the intolerant. But secondly and almost more importantly, because the tolerant are held to a higher standard. Those who hold decorum and decency within them expect of themselves to follow these conventions, and are upset but more tolerant of those who do not, in comparison to the expectations they place on themselves.

It’s a slippery slope because bad faith actors are given too much leeway to say and share things unbecoming of themselves and the roles they play in society. And so it takes a lot less effort to lack decency and decorum than it does to uphold it.

Spaceship Earth

First: Two perspectives from a trip to the moon, shared by Victor Glover and Christina Koch.

“I don’t have anything prepared. I think these observances are important, and as we are so far from Earth and looking back at the beauty of creation, I think for me, one of the really important personal perspectives that I have up here is I can really see Earth as one thing.

You guys are talking to us because we’re in a spaceship really far from Earth. But you’re on a spaceship called Earth that was created to give us a place to live in the universe.

Maybe the distance we are from you makes you think what we’re doing is special, but we’re the same distance from you. And I’m trying to tell you — just trust me — you are special.

In all of this emptiness — this is a whole bunch of nothing, this thing we call the universe — you have this oasis, this beautiful place that we get to exist together.

This is an opportunity for us to remember where we are, who we are, and that we are the same thing, and that we’ve got to get through this together.” 

~ Victor Glover

And;

“So when we saw tiny Earth, people asked our crew what impressions we had. And honestly, what struck me wasn’t necessarily just Earth. It was all the blackness around it.

Earth was just this lifeboat hanging undisturbingly in the universe.

I may have not learned — I know I haven’t learned — everything that this journey has yet to teach me. But there’s one new thing I know, and that is:

Planet Earth, you are a crew.”

~ Christina Koch (See the full speech where she is talking about what it means to be a crew.)

Next: This insightful perspective from physicist Brian Cox.

“There’s only one interesting question in philosophy. The interesting question is, what does it mean to live a finite, fragile life in an infinite, eternal universe? I think the answer is, paradoxically, whilst we are definitely physically insignificant, I’ve just said that the Earth is one planet, around one star, amongst 400 billion stars, in one galaxy amongst two trillion galaxies, in a small patch of the universe, right?

So we’re definitely small, you can’t argue with that, we’re just specks of dust. But if you think about what we are, we’re just collections of atoms. Our bodies were made in stars, right? So it’s all cooked over billions of years. And we’re in this pattern that can think, you have a means by which the universe understands and explores itself, which is us. And that sounds unlikely when you put it like that, that you can have a few things that were cooked in the hearts of stars, you stick them together in a pattern and suddenly it has some ideas and starts writing music.

There aren’t any other worlds where this happened, certainly in our galaxy. So it could be that this planet, notwithstanding its physical insignificance, is the only place where anything thinks.”

~ Brian Cox

We don’t often think of the significance of this tiny blue marble we live on. We don’t often ponder the idea that we are a single species cohabiting with other living organisms on an oasis in a sea of emptiness beyond our atmosphere. We don’t recognize that we are all connected, all crew, on a spaceship that is bigger than our political and cultural differences, bigger than the borders of our countries.

We are all crew on spaceship earth, our mother ship that supports us, and in turn we need to nurture and support her.

A tidal wave of spam

Leave a reply

Head of products at Twitter/x.com, Nikita Bier, said this on February 11th, 2 months ago today:

“Prediction: In less than 90 days, all channels that we thought were safe from spam & automation will be so flooded that they will no longer be usable in any functional sense: iMessage, phone calls, Gmail.

And we will have no way to stop it.”

Anthropic’s newest AI model, called Claude Mythos, is not being released to the public due to concerns about its ability to uncover high-severity cybersecurity flaws in major operating systems and web browsers. But make no mistake, this AI version and more (some privately owned and some free and open source) will be available in the next month. With this will come a tidal wave of security breaches, identity theft, and corporate as well as personal blackmail crimes.

The fact is that these AI models are professional lock pickers put in the hands of anyone who wants to use them. Almost no skill needed. Unlike the movies where the people doing a heist needed to recruit that one-of-a-kind safe cracker with crazy skills, now a 15 year old in his parent’s basement can do it without leaving the house.

This wave of ‘safe crackers’ is going to be let loose soon. But something else is headed this way and that’s the scammer coming for you and me via our phones, laptops, and social media accounts. These used to show up in poorly written emails, or broken English texts and phone calls that made them easy to detect. Now three things have fundamentally changed:

1. The quality of the messaging is flawless;

2. The ability of spammers and scammers to target you and share enough information to seem legitimate;

3. The sheer volume of spam coming our way. 1 spammer used to mean 1 phone call at a time being followed up with a real person. But with AI agents, one command could unleash wave upon wave of simultaneous emails, phone texts, and messages across many social media platforms.

The biggest problem with AI in the next 5 years isn’t what AI can do on its own, but rather what people with bad intentions can… and will… do with AI. It’s bad faith actors who will be our nemesis. Ultimately, the tidal wave is coming, “And we will have no way to stop it.”

Mental gymnastics

Leave a reply

I know it’s a very small percentage of people in the world that think the world is flat, but this group fascinates me. You’ve got to be a special kind of stupid to live in 2026 and think that every scientist and millions of others are all conspiring to fool you. The mental gymnastics needed to ignore blatant evidence and then double down on thinly veiled lies and poorly contrived talking points has to far exceed the effort to actually look at the obvious evidence. How much must it hurt to admit you are wrong to continually have to fight logic, facts, and data that contradict your beliefs?

Meanwhile, the rest of the world can marvel at Artemis II, travelling to the moon and back , and sharing incredible photos of this pale blue marble that we all live on. There is so much we still don’t know about the universe we live in, mysteries still to be solved… and here is a group of people who not only fight science with oblivious imagination, they hide from the enjoyment of seeing our globe from angles we have not enjoyed in decades, at resolutions we could not have previously imagined.

Maybe Artemis II will be the thing that has flat eathers ‘come around’ to the global reality… but stupidity defies logic, and I’m afraid the mental gymnastics will continue to work against people dedicated to sharing their ignorance in a loud, proud, uninformed, and uneducated way.


So easy to cheat

Leave a reply

We aren’t far away from contact lenses that can do the same. The article, ‘Smart Glasses for Exam Cheating: Best Models, Prices and Risks in 2026’, shares multiple options that can provide AI delivered test answers, in seconds, via a small ear piece or even projected text answers which can only be heard or seen by the user. Banned? Of course. Easily detected? Not all models, with more sleuth and hidden models being developed every day. And as mentioned, what happens when these are as invisible as contact lenses?

Make no mistake, cheating has been around as long as tests have. In some respects this is not new. But most methods of cheating demand guessing what questions will be on the test in advance. Methods like these are responsive to every question asked. And the speed of responses are natural. While you are still reading the question, a response is already headed your way. No need to shift your eyes from the screen or test paper. No hidden notes to conceal, and no wrong answers unless you are choosing to get less than a perfect score, to not seem suspiciously smart.

I remember a friend telling me about him and his friends getting hold of their ethics exam a couple days before they had to write it. The irony of cheating on an ethics exam is not lost on me. They memorized the questions and answers, and all chose different ones to get wrong, while still achieving high ‘A’s. Then on the day of the test my friend was horrified when his friend raised his hand 30 minutes into a 3-hour exam, and shared a typo on a question that no one should have gotten to in such a short time. Despite this poor choice, they all got their ‘A’s.

That’s going to be the new challenge in cheating, how to not do too well to bring attention to yourself. A good problem to have for a cheater.

So here we are in a new era of cheating. Prescription glasses, hidden cameras and microphones, and curated wrong answers. And in all honesty, less and less opportunity for detection. Ultimately, it’s the tests that will need to change.

In living satire

Leave a reply

A few years back I heard someone say that we are living in the timeline that is the laughing stock of all other timelines, and I’m routinely reminded of this.

I read a quote from the leader of the most powerful nation in the world today, shared in a social media post commenting on it, and my BS detector went off. This had to be fake… satire to anger those not intelligent enough to get the joke! So I went onto the web version of this man’s social media propaganda machine that bears the word ‘Truth’, (again this screams satire), to see if the quote actually came from the horse’s mouth.

It did.

He actually said this ridiculous statement. I know what you want to ask. I know I’m being too vague, and you are wondering, ‘What did he say this time?’ But here’s the sad truth: I could have written this a week ago, a month ago, a year ago… the only thing that would be different is the quote itself. Not the fact that it’s so obtuse that it is offensive. Not that it’s a disgrace to the office he holds. Not that it’s so off colour that you’d think it was satire if you didn’t read it at its source.

So here we are in living satire. Living in a joke of a timeline, where we can’t distinguish the difference between the truth and what is satirical, fake news shared on ‘The Onion’. And here I am writing a post that will be just as relevant a week, month, or year farther into our comical, if not sad timeline.

…and rest!

Leave a reply

The one area of my life that most needs fixing is sleep. While I don’t dwell on the numbers, (that would stress me out), my Garmin watch averages my score at 48/100 over the last 4 weeks. That is by no means something to be proud of, especially when half of that time was when I was on holidays.

I have a few strategies in mind to improve this, but I’m also keenly aware that worrying about my score is not a way to improve it. Still, if there is an area of my life that I know can improve my health and longevity, better sleep is probably my highest priority.

Another related area is rest between workouts. My discipline and dedication to fitness has not necessarily been all positive. After all, it was extended rest (with accompanying massages and physiotherapy) that finally rid me of months of sciatic pain down my leg. Then I came fully back into working out and today I could feel my pecs, my lats, my triceps, my quads, and my hamstrings, which are all a little sore. Yes, it’s a good kind of ‘I worked these muscles well’ sore, but that’s a lot to feel all at once. So today I rest.

After writing this, and before bed, I’ll meditate and stretch. I need to remember that giving my muscles a rest is as important as giving both body and mind a rest during sleep. It doesn’t matter if I’m working different muscle groups on different days, I still need to put full gaps in between workout days.

I thought I was being smart, not yet going back to weekly sprints to work on my Max VO2, and giving my legs and back a little longer to recover. This week I was also working with slightly lighter weights, not getting near my maximum weight on any sets. But my body still told me that I’d done more than enough. That said, 6 months ago I would have made this a cardio day instead of a full rest day. Maybe I’m learning.

Maybe I’ll go beyond listening a little more closely to my body, giving it needed rest when it tells me. Maybe I’ll integrate rest as a regular part of my routine. Thats my new plan. It starts today with a stretch and meditation to end a very mellow and exercise-less day.

A new groove

Leave a reply

It wasn’t that hard getting up on Monday morning at 5am to get to the gym. Coming back from a two week break didn’t hurt that much. But getting back into the routine of writing before I got to the gym at 6am has been a struggle.

It’s almost 11pm now and I’m laying down on my couch rattling this off to keep a commitment to myself to write every day.

The thing I am most looking forward to with retirement is time to write. The idea that I can schedule writing time that isn’t rushed excites me. Not having to think up ideas on the toilet first thing in the morning, or while washing my face and brushing my teeth. Not having to edit my work while on a treadmill. Actually sitting at a laptop with a coffee in my hand rather than hunting and pecking away on my phone… these are things I can’t wait to do as part of a daily routine upon retirement.

Before the March break people would ask me if I’m excited about my pending retirement and I’d answer honestly that I haven’t thought much about it. Now, after the break, I can’t say that anymore. I am thinking about it. I’m wondering how to design my days? I’m looking forward to finding a new groove that doesn’t involve a 5am wake up time and rushing to get my whole routine done before starting a long day at work.

The real test will be next September, when everyone is back at work and I’m home. I’m confident that I’ll build a routine that works. I’ll find my groove.
