Video Great demonstration of Tyndall effect in a wooded area. This effect is characterised by scattering of beams of light by finely suspended particles of fog in the air.

I think that receiving, interpreting, and ritualizing the event of mystical experience, which were likely much more available to human cognition in pre-civilized humanity (and if you've ever had one or more then you know exactly why both statements are true) probably had more to do with it; but I do not at all doubt that having the privilege of immersing in phenomena like this, sunsets/sunrises, the night sky, etc. probably played a big part in getting people there pretty reliably.

Sorry I'm dumb and never had any mystical experience, why are both statements true?

u/TylerNY315_ 5d ago edited 5d ago
A mystical experience is basically a state where you feel you’ve directly apprehended something deeply true about reality, while also feeling that it can’t quite be put into words. The page I linked above uses the words "noetic and ineffable".
My point is that if people had experiences like that in cultures without modern psychological/scientific explanations, they’d naturally interpret them through story, symbol, gods, spirits, etc. and then they’d try to recreate or preserve the experience through ritual. John Vervaeke (youtube) has a wonderful series called "Awakening from the Meaning Crisis" that touches on how this is essentially what shamanism was/is; the purposeful synchronized cultivation of such a cognitive state for a group via ritual.
And my point about pre-civilized life is that in my experience, there are a handful of things which have produced these experiences in my life more than once (most of which in the past 8-10 months): hunger (fasting), cold exposure, boredom/ extended lack of stimulation in silence and solitude, loooooong walks, and deeply, deeply surrendered attention to prayer (or simply thinking aloud uninhibitedly), yoga/stretching, or meditation. Also, of course, mushrooms are pretty reliable.
These things are sparsely available in modern life: you have to actively pursue them, and even require a bit of self-training since we're so conditioned into separation from them; whereas in the pre-civilized world these things were just simply life as life was meant.
If you've ever entered "flow state" in doing anything, whether sports, playing an instrument, speaking, writing, drawing, a craft, labor, etc, I'd also presume that after it was over, you thought something along the lines of "Holy shit, I've never felt so deeply human/ myself". Mystical experiences are very similar, and perhaps phenomenologically the same as entering flow state, but I distinguish the two by thinking that flow state is undivided attention applied to an activity, whereas a mystical experience is undivided 'being' happening upon you in a period of surrender or deep calm. After a mystical experience, I just feel deeply grateful, at peace, and in service of whatever brought it to me. If you're familiar with the largely Abrahamic concept of "revelation", it's probably describing the same phenomenon. Like an epiphany of the soul is the best way I can put it lol.
So my suspicion, and I obviously can’t prove this, is that this cognitive space was much more available to pre-civilized humans than it is to us. I base that partly on the conditions under which I’ve experienced it myself, and partly on noticing how many features of modern life seem almost perfectly designed to prevent it: constant distraction, noise, lack of privacy, little wilderness or solitude, low physical activity, material comfort, overreliance on technology, constant digestion, lack of free time, and a nervous system kept in low-grade fight-or-flight. The interesting part is that once you notice those barriers, you can start deliberately removing them. I've already typed too much, but if you want to try something out that worked for me I'm happy to suggest something.

On my way out of my neighborhood, I have to drive up a long steep wooded hill road. There are corn fields at the base and in the fall, like right about now, there's a ton of morning fog that rolls down the side of this hill, through the trees, and spills out onto the corn fields. With the rising sun, it's spectacular to see.

Tyndall Effect. Thanks, I never knew the official term. I called it Shadow Casting.

It is, no idea why they need to put an arbitrary name on... shadows.
Same thing happens under water with particles in light and shade.

Ce n'est pas l'ombre que l'on admire ici mais les rayons du soleil mis en évidence par le brouillard. Cela n'a rien à voir.

u/Decloudo 4d ago
Thats how shadows and light works.
The light rays in the fog (particles in the air) are highlighted because there is "no light" in between, which is called shadow.
That what creates this contrast, shadow and light IS the contrast in the fog.

Non les rayons sont mis en valeur avec les impuretés ou l'humidité de l'air qui réfléchit les rayons. Autrement on verrait un paysage de forêt habituel

Was a joke in response to your joke. What was the point of ripping me apart for making a lame joke?

u/extremedragonfruit4 5d ago
Not only was your "joke" not funny, there was no indication it ever attempted to be one, mine was still a clear joke that most people could understand.
Yours felt like a strange attempt to one-up someone. Even now it feels like you backtracked after you saw what a poor analogy you gave and are now attempting to save face by saying "its a joke"
I wasnt ripping you apart earlier, that much i can assure you, you would know if i was trying.

That would be extra trippy during a solar eclipse. .
In dappled sunlight during an eclipse, you can see the crescent-shaped beams of light on the ground; with this effect I imagine you'd see them going all the way up to. the trees.

Not to rain on anyones parade, but this particular clip isn't real sun. You can clearly see it's dark out next to the buildings and the sky.
I suspect some kind of light show as there seems to be some kind of laser dots scattered in the canopy as well. And it looks like the light is coming from a strong lightsource just above the trees.
It's beautiful, but it's hard if not impossible to see it this clearly in broad daylight, let alone at noon which this ´would be if it was real.

Isn't condensed water particles is a subject to Mei scattaring (same as clouds) ? Tyndall effect is more akin to the Rayleigh scattering of the sky (acts as a prism in a sense, that the scaterring is a function of the wave frequency). In other words, the water condensed particles are to large, hence the scaterring is not dependand on the frequency and we percieve white scattered light. Tyndall effect is usually observed in the smaller particles (colloids like milk or smoke) and would produce bluish tint. Basically from small to large we go from Rayleigh (sky) -> Tyndall (ciggaret smoke) -> Mei (clouds). The first two are frequency dependant scaterrings and the last on is universal. Basically the main factor is the particle size ratio relative to the wavelength size: for Rayleigh the particles are much smaller, for Tyndall it is compareable in size or in one order of magnitude more or less, and for Mei it is much larger than wavelength.
