Is infinity scary?

Yeah, exactly.

The example that most directly blew my mind was that a rainbow literally doesn't exist without an observer. The observer is a necessary variable for the existence of the rainbow. And that's just the esoteric example that the mind can most easily grasp. The same holds true for, say, a basketball. Mind blowing.

How does a rainbow literally not exist without an observer?

The problem with the lay understanding of stuff like this is that it can be extended to pretty much anything and is taken to an everyday physical reality rather than a mostly theoretical metaphysical one. 

 

Does color exist without an observer? That's the basic question. "Color" is, for the most part, simply the result of certain wavelengths of visible light being absorbed and reflected. But the term "visible light" itself actually implies that in order for it to be categorized as such it must be observed. So is that imprecise language or a reflection of reality?

 

If it can't exist without being observed, then there's questions about every discovery made in space, to include our neighboring planets. Did Mars pop into existence the moment the first human saw a dim red star in the evening sky? The question answers itself.

"A rainbow does not exist at a particular location in the sky. Its relative position depends on the position of the observer and the sun. All raindrops refract sunlight in the same way, but only the light from some raindrops reach the observer's eye. This light is what constitutes the rainbow for that observer."

"Rainbows are formed when light from the sun is scattered by water droplets (e.g. raindrops or fog) through a process called refraction. Refraction occurs when the light from the sun changes direction when passing through a medium denser than air, such as a raindrop. Once the refracted light enters the raindrop, it is reflected off the back and then refracted again as it exits and travels to our eyes. "

https://www.rmets.org/metmatters/how-are-rainbows-formed#:~:text=Rainbows are formed when light,air%2C such as a raindrop.

While the conditions for and phenomena associated with a rainbow exist in and of themselves, the experience we knows as "rainbow" requires an observer. It is our experience of seeing light and color, and our position relative to the meteorological phenomena present, that produce the "seeing a rainbow" experience.

Sense experience, relativity. and the inseparability of "observer" and "thing being observed" are the critical factors.

For a deeper dive down that rabbit hole, I'll refer to the erudite fellow in my avatar, Mr Alan Watts, though this is only for those that wish to go further down the rabbit hole, like Royale with Cheese after he ate his edible:

"A still more cogent example of existence as relationship is the production of a rainbow. For a rainbow appears only when there is a certain triangular relationship between three components: the sun, moisture in the atmosphere, and an observer. If all three are present, and if the angular relationship between them is correct, then, and then only, will there be the phenomenon 'rainbow.' Diaphanous as it may be, a rainbow is no subjective hallucination. It can be verified by any number of observers, though each will see it in a slightly different position."

"Today, scientists are more and more aware that what things are, and what they are doing, depends on where and when they are doing it. If, then, the definition of a thing or event must include definition of its environment, we realize that any given thing goes with a given environment so intimately and inseparably that it is more difficult to draw a clear boundary between the thing and its surroundings."

If you find your foot stuck in the railroad tracks with a high speed train approaching, just put on your headphones and close your eyes. All will be fine. 

 

 

As far as you know.

I thought he was talking about the observer effect and quantum decoherence. Rainbows exist regardless of an observer. It's like saying if you close your eyes your reflection in a mirror doesn't exist.

Time doesn't exist.  Nor does momentum in sports.

Those were some good edibles.

Actually, for some obscure reason I don't understand, it was the infinitesimal -- not infinity -- that quite literally scared the bejesus out of the powers that be.

"Geometry is orderly. It is absolutely certain. And once you get results in geometry, nobody can argue with you," Alexander says. "Everything is absolutely provable. No sane person can ever dispute something like the Pythagorean theorem."

That orderliness had captured the attention of the Jesuits, who had been trying to cope with the crisis of the Reformation.

"If we could have theology like that," Alexander explains, "then we could get rid of all those pesky Protestants who keep arguing with us, because we could prove things."

But the debate over infinitesimals threw a wrench into that thinking.

The whole point of mathematics was to be certain, Alexander says. "Everything is known, and everything has its place, and there's a very orderly hierarchy of results there. And now, in the middle of that, you throw this paradox, and you can get all those strange results. That basically means that mathematics can't be trusted, and if mathematics can't be trusted, what else can?"

The 17th-century rivalry between English philosopher Thomas Hobbes, left, and English mathematician John Wallis lasted decades.

So the Jesuits waged a war of letters, threats and intimidation against the supporters of the infinitesimal, a group that included some of Italy's greatest thinkers — Galileo, Gerolamo Cardano, Federico Commandino and others. In Italy, the Jesuits' victory was complete.

 

Ponder that the next time you have "back pain."
