The Unreality Within #17 #cong23 #reality

Synopsis:

Reality is defined by the brains of humans. Brains of humans are the product of a fallible and undirected process of evolution. Here, Brendan cite examples from his own life where the reality of his perceptions were questionable, emphasising the need for communication, collaboration, and rational reflection in the search for the impossible: Objective reality.

  1. Don’t trust your senses.
  2. The brain is incredibly powerful – not always in our favour
  3. In situations where reality is in doubt, find other witnesses and try to avoid conforming your accounts of what happened.
  4. Beware the echo chambre.

Fundamental forces.
Gravity, Electromagnetism, Weak and Strong Nuclear Forces, The Higgs Field, Quantum mechanics…
Elementary particles.
Quarks, leptons, neutrinos, electrons, positrons, photons, muons, gluons…
Atoms and light.
Molecules.
Substances in sheets and knots and ropes.
Substances that react to electron flow with a physical contraction.
Substances that react to electron flow with a chemical release.
Substances that change in chemical reactions.

Substances that combine all these structures and reactions into nerves that transmit impulses to other structures that carry out complex chemical and electrical and physical routines as a result.

Substances that think about these inputs and believe they know what this thing called “REALITY” is.

I am one such substance – or more accurately, I’m a conglomerate of many substances that influence and react with one another according to patterns set down by 4.5 billion years of trial and error.

To believe that I could be unerringly correct in what I interpret as being “real” is arrogant folly. I’m the result of hundreds of thousands of generations of creatures that succeeded to the point of reproduction – but to reach that milestone does not actually require a realistic outlook on my environment.

When I was a kid, I used to imagine my senses were lies – that I was a specimen in a vat being fed false experience so I could be observed and studied by some congregation of superior alien beings just a few feet from me.

Many years later, The Matrix came out, and I realised I wasn’t the only person to experience that suspicion. Years after that, I finally realised that the word “Solipsism” encompassed that feeling: “Maybe I’m the only thing that’s real”.

When I was in the scouts, my entire troop managed to convince ourselves that we had seen the ghost of the groundskeeper of the ancient hostel we were bunking in. A ghost we knew to expect because of the scout leader’s adept ghost story told to us earlier that evening.

My parents and I (and many other cars in a line of traffic that night) witnessed a shape-shifting geometric pattern of glowing, featureless, flat discs hovering low over the traffic on a road through Northern Ireland in the mid-’90s. It shifted from car to car as if scanning the occupants. (despite including this one here, I remain convinced that this occurred as described)

When I was in college, I awoke unable to move one night. I’d had sleep paralysis before – I knew what it was, I knew not to fear it. What was different this time was that a noise in my (locked) room had awoken me. A swishing of fabric.

There was a woman standing behind my computer chair. The swishing noise was this interloper holding some item of my clothing and rubbing it between thumb and forefinger like its presence perplexed her.

She was dressed in a white shirt blouse and a black waistcoat with black slacks, like a hotel staffer. I tried to ask her how she got in through my locked door. All that came out of my still-paralysed mouth was “hssss sss sss”. That caught her attention and she dropped the item in her hand on the floor.

She seemed to hear me, but be unable to recognise any logical source for the sound. She sat on the edge of my bed and searched with her ear for the sound. Despite having turned toward me, her face stayed dark, it was like her hair cast an impossible shadow, or like there was no face in there at all.

As I continued to hiss unintelligible questions at her, she zeroed in on the sound with her ear until she was leaning right over me.
It was at that point that the muscles in my torso woke up, and I sat bolt upright almost involuntarily. I headbutted my way through her head and the woman burst into motes of vapour and dissipated.

I sat there for a few moments contemplating what had happened, observing the room.
She had left an imprint on the bed where she sat.
The item of clothing she dropped on the ground was nowhere to be found.
I examined myself: Cold sweat, heart hammering in my chest. The outward manifestation of fear. Inwardly, I felt calm and curious: Had I really just witnessed a ghost?

I thought on that: This was a new house. My housemates and I were the first occupants after its construction. As far as I was aware, this was farmland prior to the construction of the estate. The woman was dressed like a modern professional woman. None of this fit the usual haunting tropes.

I turned on my computer. I set the power settings to leave the monitor active overnight, opened notepad, set the text size large so it wouldn’t be missed and typed “Ghost-Girl: If you read this, type something here”. In the morning, nothing else had been written.

A few days later, a psych-student friend of mine told me about “Sleep Hypnagogia”, a failure of the wake-up routine where your brain keeps dreaming images into your perceptions while you’re awake. In reading up on it, I found accounts of witch and alien and ghost encounters that often had amazingly coincidental details with my encounter, like seeking the sound and popping into a cloud of vapour when impinged.

I list these events because they are (for the most part) examples of the machinery I use to interrogate and define my reality… failing.

Reality at its most fundamental is inaccessible to us. We cannot taste quarks or witness molecules bonding. Our senses, insofar as they can be trusted, are sensitive to macro-scale events – that which mattered in our evolutionary past. As such we take shortcuts, we generate abstractions and synthesise based on inference.

Reality will therefore, unfortunately, differ depending on who you ask. We have processes and technology to compare and contrast our realities to varying levels of rigour. These range from simple communication at the most primitive, to the Scientific Method at their height.

Somewhere in the middle, sits CongRegation.

Purpose In An Uncomprehending Universe. #34 #cong22

Synopsis:

As a space-focused STEAM communicator, I argue that the vast and creepily silent universe we have revealed through science shouldn’t be a reason for feelings of despair or insignificance, but of specialness and purpose.

Key Takeaways:

  1. You are made of the universe
  2. Generations of stars died so that you may live.
  3. So far as we have verifiably discovered, life and intelligence exist only here.
  4. We owe it to the rest of the insensate universe to experience and understand as much of reality as we can.

Finding Purpose In An Infinite Cosmos

I’m a space-nut and a hobbyist astronomer. I grew up watching Star Trek and other sci-fi on TV and thinking that the real life universe was a bit bland in comparison.

About 15 years ago, I started taking an interest in the reality of space travel and the universe – thanks to a combo of finding my brother’s old telescope in the attic, watching Carl Sagan’s seminal 1980 docuseries “Cosmos”, and the first credible rumblings of renewed space exploration ambition coming from the private sector.

What I realised as I absorbed more and more science information about deep space phenomena and the evolution of galaxies, stars, planets, and nebulae, was that I wasn’t learning about some abstract, out-there, irrelevant construct that is completely divorced from lived reality… I was learning about us – I was learning about me.

And… I was learning about you.

Look at your hand. It’s a collection of meat, sinew, and bone. Those materials are made of molecules. Those molecules are arrangements of atoms that used to be part of the Earth or the air, until they were eaten or breathed, by you or your parent (or your food’s food’s food) and eventually found themselves arranged by astonishing natural processes of chemistry and physics into the structure you are probably now inspecting and wiggling and feeling a bit alien about.

But wait, where did the atoms come from that comprise the molecules that constitute this strange meat-spider that you puppeteer on the end of your equally mysterious arm?

The obvious, and correct – but incomplete – answer, is the Big Bang.

The Big Bang is the origin of all matter in the universe, but the matter created at that instant 13.82 billion years ago was mostly in the form of the simplest elements like hydrogen and helium. It was almost completely smoothly distributed throughout the universe, but minor density variations caused some regions to have more gravitational pull than others, causing the gas to collapse in on itself and ignite the nuclear fusion furnace of the first generation of stars.

Furnaces are an apt metaphor for stars because, just as furnaces forge new alloys, stars forge simple, light elements into heavier ones – and then, with a bit more effort, fuses those into even heavier ones.

Stars are stuff-making machines, taking fuel like that abundant hydrogen and helium, and making heavier elements like oxygen, carbon, calcium, potassium, sodium, etc. fusing progressively heavier elements in the unimaginable heat and pressure deep within.

As the matter in a star is converted to heavier elements, it takes ever more heat and pressure produce ever-heavier atoms. The process stops short in and around the production of lead, which is so hard to make that the star quickly runs out of fuel.

The fusion furnace at the heart of a star is very much the same kind of fusion that occurs in a fusion bomb, but it is continuous. For as long as there is stuff to fuse, it fuses and explodes, fuses and explodes, non-stop, for millions or billions of years.

It’s the tenuous balance between the inward-pulling force of gravity and the outward-pushing force of that constant explosion that keeps the star spherical in shape.

Once the fusion explosion stops, gravity “wins the fight” and the star collapses in on itself. This final collapse (among other similar processes) is where most of the heaviest elements like gold and uranium are made. In those few moments (literally seconds or minutes) that it takes for the squelching gravity of the star to pull the now-unsupported bulk of its matter down on itself, falling matter collides with enough punch to fuse the heavier stuff.

The fall ends when the star’s matter bounces off the core in one last titanic fusion explosion It’s so powerful that it sprays the matter comprising the star (all the “stuff” its lifetime of progressively-harder fusion has produced), into the surrounding space as swiftly-cooling gas and dust.

That gas and dust eventually collapses to form new stars and planets, and some of those stars live out their life cycles and explode too, adding to the soup of fusion-enriched star-guts floating thinly in space. These cyclical births and deaths of stars gradually filled the universe with the ingredients for rocky planets and fleshy apes like us…

… And yet in all of that, we haven’t yet found credible evidence of other intelligent life forms.

We are animate star-matter that has evolved through gravity, fusion, and natural selection to the point of being able to comprehend our own atomic nature and origin… “a way for the cosmos to know itself”, as Carl Sagan so peerlessly expressed it… but we seem to be alone. In a vast and apparently uncomprehending universe, we apparently have the only eyes, the only ears, the only hands, and the only brains capable of synthesizing what our senses tell us into a convincing estimation of reality.

To hope to comprehend even 1% of what we now believe to be the extent of reality is ludicrously ambitious, but if it’s purpose you seek, what better is there than this:

To be the universe’s senses. To learn and experience as much as is accessible to us. To live well and learn always and pay back the good fortune of our own existence by aiming to know as much as can be known.

That’s what I call purpose.
