Gravity too
Also magnetism
As one of the great scholars of our time has said:
“Nobody knows what a magnet is.”
I think it’s in the list as “heavy stuff”.
I took that to mean singularities
Turbulence can go to hell and take Reynolds numbers with them
Turbulence seems to be to be deterministic chaos, that if we had perfect resolution, and unlimited processing power, we could predict turbulent flow with precision.
I prefer not to reference deceased scientists & philosophers because it makes me appear old. I prefer to only acknowledge the wisdom of contemporaries such as Jordan Peterson & Neil DeGrass Tyson so people don’t think I’m elderly.

Not even clear why hot water freeze faster than cold one.
I don’t think this is true. Just a myth or it only occurs in certain circumstances.
Not a myth, it’s known as Mpemba effect, several hypothese about it, but still not clear
In 2016, Burridge and Linden studied a slightly different measure, the time it took water samples to reach 0 °C but not freeze. They carried out their own experiments, and reviewed previous work by others. Their review noted that the large effects observed in early experiments had not been replicated in other studies of cooling to the freezing point, and that studies showing small effects could be influenced by variations in the positioning of thermometers: “We conclude, somewhat sadly, that there is no evidence to support meaningful observations of the Mpemba effect.”
From the Wikipedia article.
i mean, you’re really burying the lead there when the article states pretty clearly in the abstract that the existence of this is contentious.
your quote doesn’t really demonstrate it doesn’t exist, it just demonstrates what the article already clearly states which is that people don’t agree.
it’s disingenuous to quote that specifically while ignoring things like:
In 2021, John Bechhoefer described a way to reliably reproduce the effect.[23] In 2024, Argelia Ortega, et al. studied the freezing of small (1-20mL) drops in a Peltier cell with a thermographic camera, and found that hot drops consistently froze faster than cold ones, with a more pronounced difference for larger drops. In particular, hot drops finished freezing sooner after the onset of recalescence, and experienced less of a temperature spike during the freezing process.[24]
from the exact same article, is all i am saying. bad rhetoric.
All models are wrong. Some are useful.

Galileo was actually very bad at science.
We have figured out big stuff and small stuff very well! And if it weren’t for the little fact they share the same universe, it would be very good general theories.
No way I live long enough for us to get to a Grand Unified Field theory. :(
Didn’t scientists just prove a unified theory was impossible?
What a bunch of nonsense. So, pseudo-scientists repeat after me: you cannot derive rules of the outer universe from the inner universe.
The only way to “prove” the hypothesis is if an admin sends a message or leaves some other way for us to discover we’re in a simulation, other than that it’s unprovable and undisprovable.

No, we can’t prove we’re in a simulation or outside of it. We can prove that we can’t currently create such a simulation but that doesn’t change anything.
