One of the best examples of that is Brian Josephson, the Nobel Prize wining Welsh physicist who derived the equations for the Josephson effect when he was in his 20's. This knowledge was then used to create the 'Josephson junction'. He later got involved in parapsychology and all sorts of 'spiritual stuff'.
https://en.wikipedia.org/wiki/Brian_Josephson (I also google so you don't have to 😉 )
Many of the ultra-high accuracy voltage references are now based on the Josephson junction and NIST developed one that was used by HP i.a.o. in the development of their 8 (maybe 9?) digit DVM's - we had one where I worked back in the early 1980's.
There is something vaguely related. Increased water vapour levels in the atmosphere. That tends to produce misty views of the horizon. Not far off the usual view these days.
You can look up Climate Change and Greenhouse Gases with trusted sources:

The Earth would have a mean temperature around an eye-watering -18C without Water Vapour, Carbon Dioxide and I suppose Methane. As it is, it is 15C before humankind's unwanted additions.
I'd guess Nitrous Oxide and Fluorocarbons are the new addition, plus more methane and CO2. And it takes about a hundred years for most of them to dissipate even if we seriously started to tackle it now now.
Anyway back to Gravity. I am slightly hurt that Bonsai says I don't provide answers. But really this is because I don't have any. But study harder than most. Do you?
Here's my findings on time dilation due to gravity and orbital velocity:
https://en.wikipedia.org/wiki/Gravitational_time_dilation
All seems to make sense, and orbital energy is much less significant than gravitational potential energy here. Variations on the Lorentz transformation.
As for Grand Unified Theories, we have 4 mainstream ones so far. And all are at least 100 years away in terms of real solutions in mine and Ed Witten's opinions, and often only work with 2D plus Time Toy Models:
The Standard Model.
String Theories.
Loop Quantum Gravity.
Quantum Holonomy Theory.
So I'm more interested in getting a real grip on Special Relativity which is fascinating, but not too hard, which is the right sort of problem to grapple with.
Quantum Holonomy Theory? Well here it is:
Hmm. Maybe. As good as anything I suppose. 😵

Yes, Vishal, that’s right, the air quality here in Wash. DC has never been better, ever. All the govvies and everyone else working at home please continue to do so. About the time the Clean Air act was finally passed in 70s the night sky would sometimes be purple and yellow, which wasn‘t that bad artistically but the problem was you were breathing it. Suu Bha Pra Bhat from the center of the beast.would you believe I have on my Himalaya Everest t shirt right now?
My deepest apologies Steve. That is a nice graph you posted and leads me to conclude that if time is malleable in the fashion depicted, it cannot be an illusion. It must be a ‘thing’.
😉
Quote from video: "QHT mathematics gives us more than just the Standard Model."
I read that:
"Quantum Holonomy Theory is an attempt at explaining the mathematical properties of the fields that occur in the standard model in terms of 'holonomy'."
So, what is 'holonomy'? Something to do with geometry (or is it toplogy) it would appear.
I found this layman's explanation:
"Parallel parking! You reverse, turn your wheel right, go forward, turn your wheel left, repeat. At the end, your wheel is where it started, but you've transported horizontally. This net shift is holonomy."
More here:
Argon Ash’s videos are superb - the above one on QHT being a good example. No bs, just facts.
@gpauk Look on the bright side, it doesn’t induce necrophilia, at least I hope not. 😦
Say, whatever became of all the UK audiophiles? Did they all pack it in and become pseudo skeptics? I supported a Scottish company Precious Music years ago at the big Heathrow audio show, was it HiFi News, that got best of show, at least that’s how I remember it.

If you 'get stuck' on a hypothesis strong enough, you'll start to reinterpret facts as supporting your hypothesis.

Is the word derived from hologram? Or maybe holism? The word holistic gets used in many ways, including "spiritual," implying connections between things for which there's no evidence (or only the "evidence" that "oh, it seems like it must be true"). I don't find it useful.
Maybe I'm caring less about all these "theories" er, hypotheses (when discussing science, even to a lay audience, IMO one should use proper nomenclature) than when I was younger.
This is one of the best writings I've seen recently:

I don't recall ever having given a personal opinion on whether time is illusory or real.
In his book, 'End of Time', Julian Barbour disagrees with Lee Smolin that time is real and says that time simply does not exist!
"He (Barbour) argues that the Universe is really a vast, static array of ‘nows’, like frames on some cosmic movie-reel. At any given moment, or ‘now’, time does not need to be factored in to explanations of how the Universe works. The sense of time passing comes from our minds processing each of these frames – or ‘time capsules’, as Barbour calls them. Time itself, however, doesn’t exist."
Science fiction and science fantasy provide wondrous arenas in which to play with the concept of time.
Michael Moorcock wrote a series of novels and short stories about the 'End of Time', an era "where entropy is king and the universe has begun collapsing upon itself". I read many of Moorcock's books when I was young and still hooked on fantasy fiction. Music lovers will remember Moorcock from his association with rock band 'Hawkwind' and their album 'Warrior on the Edge of Time'.

That's a challenging read, benb.
I'll have to google for the 'Reductionism for Dummies' version!
However, it would appear that it is meant to shatter our illusions.

I read that Heinrich Hertz, in 1894, introduced the word "holonomic" from the Greek ὅλος meaning entire and νόμ-ος meaning law.
I never use a spell checker.
That way, I never get things wrang.
P.S. "Wrang" is actually how a Glaswegian would pronounce the word "wrong".
If ye want tae learn hou tae spell, a spell checker is the "wrangweys" tae gae aboot it! 😉
