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.

“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. 

A quiet mind

While we don’t sit in silence very often (yesterday’s post and one from 2022), we also don’t sit with a quiet mind. Our ‘To Do’ list, obligations, and plans fill our mind with things in the future rather than the present.

The idea of stillness eludes us even when it’s quiet. The notion that we are fully present escapes us. A happy experience? Let’s take a photo to remember it. A pretty sky? Let’s take a video. A beautiful walk? Let’s plan our next meal. We seldom stay in the moment.

Maybe it’s just me and my monkey brain. My brain that tries to meditate and spends its time wandering. I want to wonder but I wander. I want to be quiet and still but I fidget internally as well as externally.

I want the gift, the present, of being present. I seek the now and not the future… Not the thoughts of what’s next, what I must still do, and what I should or should not say to someone not currently with me. Imagining future conversations, or worse, past conversations and how they could have been better.

A quiet mind is not an empty mind, it’s a mind focused and aware of the now. It is not in the past or the future, it is in the presence of the present. I will meditate after writing this. Meditation must come after writing or I’m even less present as I think of what I’m going to write. Even then, my mind will drift, I will accept it and understand that refocusing is part of the process, it actually is the process. But I long for the quiet, the stillness, the moments where I’m fully present.

Perhaps it’s that very longing that prevents me from getting there. The desire to be more present is a desire and want of something not in the the present and thus something I can not seek without being less present. It’s the paradox of letting go: the more you try to let go, the more you are holding on to something… the less still your mind is.

Not a question of first or rare or distant

When thinking about whether we are alone in the universe or not, it seems to me that it isn’t a question of whether we (intelligent life) are rare? Or are we first/early compared to other intelligent life? Or are we simply too far away? But rather a question of enduring. Are intelligent civilizations enduring enough to travel beyond their solar system or galaxy?

The Fermi paradox is the discrepancy between the lack of conclusive evidence of advanced extraterrestrial life and the apparently high likelihood of its existence. Scientists today are looking for life in our very own solar system. It’s possible, in our vast universe, that our quest for life beyond earth may be as close as Saturn’s moon, Enceladus. It would probably b\e microbes, too small to see without a microscope, but that would still suggest that life is way more abundant than even most scientists would have imagined just a few years ago.

But I’m more a believer that the reason we don’t see alien life is for two reasons, the first being distance. Quite simply, even the nearest galaxy to our Milky way is astronomically far away.  “The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.” If intelligent life started sending messages to us from the Canis Major Dwarf Galaxy 10,000 years ago, it would still take 15,000 years to reach us if they could do the unlikely task of sending that message at the speed of light… and the crazy thing is, why would they send a message our way? 10,000 years ago there was no evidence coming from earth that we are a worthy planet to send a message to!

And the second reason we don’t see any intelligent life ‘out there’ in the universe is The Great Filter. Either it is extremely rare and difficult to get beyond simple, unintelligent multicellular life, or civilizations themselves getting to multi solar system travel capabilities are extremely rare. This second point is my belief. Civilizations are not enduring enough. It took Homo sapiens 300,000 years to become a scientifically intelligent life form that attempted to leave our planet and explore our solar system. During this time, we’ve been brutal to each other. We’ve created weapons of mass destruction and quite literally drawn lines in the sand to keep us separate from our brothers and sisters.

We’ve created religions that don’t like each other and think all other Gods are unworthy of following. We’ve created borders that keep ‘others’ out. We’ve created governments that are more interested in power than in caring for fellow humans. We’ve created corporations that worry more about profit than about caring for our planet. All the while we also create technologies that threaten the longevity of humanity. As technological innovations occur, it becomes easier for individuals and small groups to terrorize larger groups. It becomes easier for a single unstable person to threaten larger and larger populations around our planet.

What happens 50 years from now when a kid can create a devastating bomb or virus in their basement with readily available resources? Is that a world where we continue to advance technologically? Albert Einstein is often quoted as having said: “I don’t know with what weapons World War III will be fought, but World War IV will be fought with sticks and stones“. In other words, we will destroy ourselves and become far more primitive, much less advanced. Imagine our world with no power grid, and no internet. How long would it take to get back to where we are now? What if the next pandemic is far more deadly and has us living like subsistence farmers, keeping ourselves in tiny communities, afraid of outsiders. How many hundreds of years would we be set back, and would we be trying to explore the cosmos when survival is our greatest concern?

I tend to be an optimist, and I’m excited about the future ahead of us. I think my kids have the potential to live healthy, productive, and cognitively sound lives past 100 years of age. I think there will be universal basic income for every human alive, and that things like childhood starvation and extreme poverty could come to an end. Technological advances could make us live healthier, longer, more fulfilling and creative lives. But I also fear that greed, power, and beliefs in bad ideas could corrupt us, and undermine our potential. Are we 50, 100, or 1,000 years away from ravaging our planet or at least the human race? Or are we a species that will populate other parts of our galaxy?

If I was an alien who came to explore earth today, I’m not sure I’d report back to my planet the the inhabitants are intelligent? I’m not sure I’d consider humans technologically advanced enough to seek contact? I’d be conveying that earthlings are as likely to destroy themselves as they are to send someone out of their own solar system. I’d send a message home and say, ‘Let’s leave them alone for now and see what they can do in another couple hundred of their earth years?‘

‘Let’s see if this race of humans will endure?‘

More on faith and evil

A couple days ago I wrote: The paradox of religion, and this morning Miguel Guhlin responded with an insightful post: Skirting Paradox. I encourage you to not just read the post, but also to follow the links… grab a coffee and dig in, if you have any interest in faith and religion, this is a piece you’ll want to read and reflect on.

Here is my comment response, but it does not stand alone, it sits in reflection to Miguel’s thoughts and ideas and if you choose to read only one of the two, read Miguel’s thoughts above rather than mine below.

—

Miguel, thank you for sharing such an insightful post! It took a while to read because I paused to go to every link. I appreciate your links to scripture and your perspective on them. I wrote this back in March, From Faith or With Faith.

In honesty I did not remember writing this when I wrote the post above… the consequence of writing every day is that I often repeat concepts months later, not remembering what is unexpressed versus written thoughts in my mind. But the slant in the link is a little different, less harsh, less of an attack on religion (which I was concerned about, but you saw through in your response). This previous writing reminds me of a conversation I recently had with a religious colleague, whom pre-covid I often spent time with speaking of and about religion. In this conversation I said to him at one point: (paraphrasing) 

When I share my atheistic points, they are not intended to convert you. I do not perceive atheism as a religion to adopt, simply a lack of religion… there is no intent to change your mind on your faith… in fact I see how your faith grounds you and I see no benefit in you not believing what you do. 

But that is a conversation between two educators, two public school principals, both of whom do not share their religion/beliefs with students. This does not change the ideas above that you succinctly reduced to:

“What religion does to support good people is grossly outweighed by what [evil] it does.”

That is the thesis statement. That is the problem today, be it with evangelical beliefs on abortion versus the liberty of women over their bodies in the US; Or warring Shiites versus Sunnis in the Middle East; Or Chinese versus Tibetans in Asia; Or… Or… Or… the list is almost endless. Why would a benevolent, all-knowing, and un-interfering God want His/Her worshippers to impose their beliefs on others? When two people of differing faiths squabble, no finger of God comes waving down upon one of them. When that squabble leads to the use of swords or guns, no hand of God shields the supposed Righteous One. Instead, Man’s evil against Man is shed, and the God they love is no longer represented in their actions.
And there in lies the problem of religion, it does not remain in the ‘respective closets’ you mention. Instead, it manifests in hatred of the heathen non-believers. In fact, the wrath of God on non-believers in scripture is what turned me away from religion. I wondered as a teen, “What kind of cruel God would do this?”
~ Coffee after Class

“What religion does to support good people is grossly outweighed by what [evil] it does.”

Faith in God will not ever end, but maybe we can find a humanist… (I fear saying Humanist with a capital ‘H’, for this too can become dogma worth fighting to protect)… maybe we can find a humanist approach to faith that invites love of life and liberty, dialogue not conflict, and faith without evil.

Thanks again for your insightful reflection.

The paradox of religion

I know people of faith. Good people. Jews, Muslims, Christians. Good people all. Faith can be a good for people, it can anchor them, it can ground them. It can build community and a sense of belonging. But there’s a catch. It’s a big catch: Religion is only helpful to good people. That’s right, religion doesn’t make people good, it fosters the good in already good people.

Meanwhile, religion is used by bad people. Bad priests who prey on believers. Foolish people who take words from ancient texts literally. Weak people who feel hopeless and lost. And sometimes it even takes good people and clouds their judgement, turning their faith into misguided devotion.

When good and smart people who contextualize religious teachings with a morality that anchors them and their faith leave that faith, they do not suddenly become bad people. The religion isn’t a necessary part of being good. But religion is often used to to harm ‘others’; to ostracize and attack those that don’t fit. The crusades, military jihadists, ethnic cleansing, these are examples of how religious beliefs undermine morality as opposed to foster it. Man’s inhumanity against Man has often been driven by faith.

If religions were to suddenly disappear, would there be more or less violence in the world? How many good people would suddenly fall from grace? On the other hand, how many blindly devout and misguided people would suddenly have no need to harm non-believers?

Today, more hate is promoted by religion than love. This is the paradox of religion: Good people will be good without their faith, bad people will not be as bad without scriptures to misinterpret and blindly follow. What religion does to support good people is grossly outweighed by what it does to co-opt the weak, draw them in, and have them blindly follow the misguided religious teachings of men and women who misinterpret old and outdated texts.

Has religion helped some people? Yes. Absolutely. But at what price? How many have died in the name of their or other’s religions? How many continue to die? To hate? To fight? To abuse believers? To impose their beliefs on non-believers? All in the name of God.

The most powerful paradoxes of life

I just read this thread of tweets by Sahil Bloom and it needs to be shared! Click on the tweet and read them all. More than one will speak to you. These are indeed paradoxes that you will have experienced and understood intuitively at some point in your life.

Beyond that, I’ll let them speak for themselves:

The paradox of tolerance

This is a brilliant 1-minute TikTok on The Paradox of Tolerance by user @TheHistoryWizard.

Here is the key part, “We must be intolerant of intolerance… racists, sexists, etc. are intolerant of people.” As opposed to being “intolerant of ideas that are intolerant of people“.

This is an important distinction. These two things are not on an equal footing. Being intolerant of intolerance holds a moral high ground that intolerant, ignorant people do not hold.

Empty your cup

Empty Your Cup
A Japanese Zen master received a university professor who came to enquire about Zen. It was obvious from the start of the conversation that the professor was not so much interested in learning about Zen as he was in impressing the master with his own opinions and knowledge.

The master listened patiently and finally suggested they have tea. The master poured his visitor’s cup full and then kept on pouring.

The professor watched the cup overflowing until he could no longer contain himself.
‘The cup is overfull, no more will go in.’

‘Like this cup,’ the master said, ‘you are full of your own opinions and speculations. How can I show you Zen unless you first empty your cup?’

Taken From: Zen in the Martial Arts By Joe Hyams, 1979, pp. 18-19.

This is a favourite parable of mine. However there is another perspective that I take which contradicts this in one way, and complements it in another.

Yes, when you are learning something new, your previous perspective and knowledge can ‘get in the way’ of what you can learn.

But what about cognitive load? What happens when the issue isn’t that you are espousing your knowledge and blocking new learning, what about when you’ve reached the point where you feel you’ve learned too much too quickly, and there isn’t ‘enough room’ to add anything new?

(I think a few educators are feeling this now, after 6-8 weeks of remote learning.)

This is where I find that this parable becomes a paradox… when cognitive load feels too much, an instinct is to feel like, ‘My cup is full, I can’t fit any more new learning in.” When this happens, it’s actually a great time to try something new! To step out of your comfort zone, empty your own cup and play. Learn something you don’t ‘need’ to learn.

When someone is teaching you, you need to empty your cup.

When you feel like you’ve learned too much, you can add a bit more, in a different field of interest, and this will actually empty your cup a bit.

Being ignorant of your cup being full puts you in a spot where you need to empty your cup. Knowing your cup is full, you can increase the volume of the cup when you stop adding the same tea.

Do you feel your cup is full right now? Choose something completely different and interesting to learn and you’ll find more room in your cup again.
