Its more related to limits of knowability of events beyond a certain scale. Its easy an intuitive to think of it like pixels on a grid with a minimum requirement of time and energy to move between them units but its not that simple or at least that kind of granular discreteness is not proven (though there are digital physics frameworks that treat spacetime discrete like this)
The Planck length does not define the minimum distance something can move but rather the minimum scale of meaningful measurement that can make a bit of distinction between two microsstates of information.
Its a precision limit that defines how exact we can measure interactions that happen within the distance between two points.
It’s possible that spacetime is continuous at a fundamental level, but the Planck length represents the scale at which quantum fluctuations of spacetime itself become so violent that the concepts of a ‘path’ or a ‘distance’ can no longer be defined in the classical sense, effectively creating discrete quantized limits for measurement precision.
Ultimately this precision bound limit is related to energy cost to actualize a measurement from a superposition and the exponetial increase in energy needed to overcome uncertainty principle at smaller and smaller scales. The energy required to actualize a meaningful state from a sub-planck length would be enough to create a kugelblitz black hole made from pure condensed energy.

Is the speed of causation propagation linked to plank length?
Yes, more specifically the Planck length is derived from an equation involving the speed of light/causality.
Where C is light, h is reduced planck constant, and G is gravitational constant. Together they tell us the fundamental unit length of meaningful distinction, a very important yard stick for measuring the smallest distances.

I have no religious beliefs. The thing that trips me up is how is there matter in the first place if none can ever be created? Why was there stuff at a single point at some time
The “matter/information can’t be created or destroyed” thing only applies to closed systems within their own operational bounds. It’s about logical consistency within a closed set, but that tells us nothing about where the closed set itself came from. All the energy from the big bang/first universal iteration was loaned from somewhere else. The how and why of this is probably going to remain a mystery forever because our simulations of the laws of physics can’t go back to before the big bang.
So the nature of the big bang and why anything exists is one of the big open-ended philosophy-of-science questions that there isn’t an easy falsifiable answer to. It’s up to interpretation. I have my own theories on the topic but any guess is as good as another.
From the good old classic “Because God Did It™” to “bubble universes that foam out from a hyperdimensional substrate with random laws of physics/math that sometimes allow for observation and life” and everything in between. It’s all the same to me because we can’t prove anything one way or the other.
- Comment on Fictional 6 days ago:
What your asking directly stems from two related open ended philosophy-of-science questions. These would be " Are universal constants actually constant?" and “Does the speed of light differ in speed at any point of time in its journey between two points of space in a continuous substrate?”
The answer to both like all philosophy questions is a long hit on the pot pipe and a “sure man, its possible but remains unlikely/over engineering the problem until we have justification through observing it” however I’ll give my two cents.
“” Are universal constants actually constant?" " it probably depends on the constant. Fundamental math stuff that tie directly into computations logic and uncertainty precision limits like pi are eternal and unchanging. More physics type constants derived from statistical distribution like the cosmological constant might shift around a little especially at quantum precision error scales.
The speed of light probably is closer to the first one as its ultimately about mathematically derived logical boundaries on how fast any two points universe can interact to quantize a microstate. Its a computational limit and I don’t see that changing unless the actual vaccum substrate of spacetime takes a sudden phase shift.
“Does the speed of light differ in speed at any point of time in its journey between two points of space in a continuous substrate?”
Veritasium did a good video about this one. The answer is its possible but currently unmeasurable . so if all hypothesis generate the same effective results then the simplest among them (light maintaining a constant speed during both ways of trip) is the most simple computationally efficient hypothesis among them.

Do you really believe that in all of eternity, we happen to be just four and a half billion years in? We are probably on our infinite life, and have infinite more to go. Just completely random lives, no idea where we will end up, nothing persists.
Yes I do. There’s a difference between the philosophical idea of an eternal process of cosmological rebirth, and the experimentally observed behaviors of the current universe we live in captured with our most powerful instruments and our best mathematical models.
In the 20th century we built telescopes powerful enough to see into the very distant universe and track the movement of galaxies. Because of this technological achievement we observed some strange things.
First was that galaxies seemed to be moving further and further away from each other. Not only that, they were moving away at an accelerating pace. This uncovered the idea of cosmological expansion, that over time our universe “spreads out” and creates new space between already distant objects.
Second, because the speed of light is finite, this creates fundamental limits to how far we can observe (the cosmological horizon) and a crazy cool phenomenon where the further you look into the distant universe the further back in time you look due to the age of the light from the star and the distance it traveled. We can literally see how the universe looked billions of years ago and calculate how far back we are looking.
If you look back far enough with extremely low frequency radio telescopes you can map out the thermal radiation from when the universe was extremely hot and dense about 380,000 years after the Big Bang. This is called the Cosmic Microwave Background. It shows the universe was in a very condensed high energy state.
Third, we have concepts such as the second law of thermodynamics that says entropy increases in closed systems. Energy always spreads out and systems tend toward disorder on a global level. We have equations that very accurately describe this distribution.
With these breakthroughs we had enough data to simulate accurate matter distributions of the current universe, observe and accurately model matter distributions in the distant past, and use that model to find a best prediction of what may happen in the future with what we currently know. All three lines of evidence point to a universe that is roughly 13.8 billion years old with a definite beginning and end state.
This can still be reconciled with spiritual beliefs if your willing to redefine eternity to something more like an eternal cycle of rebirth with the heat death of one universe bootstrapping the creation of the next iteration. You may enjoy Futuramas bit on it.

The actual answer is because the universe had to pick a finite number and it probably doesnt use meters as an internal measurement ruler for scaling so

The point they were trying to make is meat bad and you should feel bad for eating it. Some people have no sense of pragmatic reality and need some cause to feel good about themselves, so they force everyone around them to watch food inc and virtue signal simply to fill in the void of where a real unique personality and opinion set should be. According to vegans agriculture as a whole is evil and everyone who eats a hamburger is equivalent to a sociopath who tortures animals for fun. Unfortunately they would have a point about cruelty and inhumane industrial farming practices, which is completely undercut by obnoxious high-horsing and blaming people for buying the hamburgers instead of the industry and lack of even the most basic rights for non-human animals.

The thing is that even if there isn’t much energy in plastic to be extracted, theres still enough energy in it to make a viable food source. Now, consider the humble panda and its primary food source, fucking eucalyptus leaves. Theyre so hard to chew that koalas had to spend evolutionary time and energy just to spec into it to the point they cant eat anything else pretty much. Combine that with the fact that eucalyptis leaves are so devoid of nutrients that the koala has to spend all day every day just snacking on them to not die of malnutrition.
Why? Why would a species even bother with this flim-flam if eucalypti sucks that bad as a food source? The answer is: Food scarcity. Because eucalytis grows everywhere where koalas live and because nobody else is bothering to tap into the food source, this sets up a ecological niche by pretty much gaurenteeing any animal that sucessfully finds a way to make it work will have unlimited amounts of food/energy just from the fact theres so damn much of it and nothing else wants to/can touch it. Sure koalas might have paid the price by sacrificing some brain wrinkles but who needs higher intelligence when you have leaves to snack on and sex to make babies.
A similar thing happened with trees and mushrooms. In the deep evolutionary history of our planet trees were once the apex forms of life with forest covering pretty much the whole planet. This is because nothing knew how to break down the wood making up stems for a good couple million years. Most of the coal and oil that we dig up today is actually the preserved remains of these unbroken down trees from the carboniferous period that just layed there petrified never rotting until the carbon compressed into hard rock or squeezed into liquid. The great change in the era happened when our humble mycelium bois finally figured out how to eat wood, causing them to essentially become the new apex life for a time.

All these big companies think they’re hot shit and have been gaslit applicants into thinking this is an appropriate process that everyone should go through if they want to make ‘the big bucks’. No you idiots, the job market is in the hands of the worker selling their labor. The interviewee is the one interviewing the companies, the interviewee should be the one to make them jump through 15 hoops only to be rejected, or your skills aren’t all that unique in terms of bargaining. If I have to spend more than five minutes applying through your dogshit website or if you even think about wasting my time with long interview stages+handwritten testing like im back in school then you can suck on my nuts and find someone dumb enough to bite because of the bait of a big paycheck.

Assuming its empty, i would take the grog oggah boogah solution of smash the blue plastic bowl down the edge of your countertop. Something will give sometime.
Otherwise, did you try twisting the bowl super hard? Torque is typically a more effective force than pulling for friction.

Hi Hawke, I understand your fustration with needing to troubleshoot things. Steam allows you to import any exe as a ‘non-steam game’ to your library and run it with the proton compatability layer. I sometimes have success getting a GOG game installed by running the install exe through proton or wine. Theres also some linux distros that come with proton installed. Hope it all works out for you

assuming you use steam, see which of your favorite games run with proton compatability layer and which absolutely require windows. You may be suprised.

In reality im neither an undergrad nor a post doc nor anything in between. I’m just some schmuck with a STEM degree.

Ez. I put myself into a box with a lever and a bomb. The bomb is activated by an OR gate with one input being 50% chance activated if the lever is pulled, and the other input is attached to an uncollaped wave function with a 50% chance of being measured or not.
This allows me to enter an undefined state beyond life and death, beyond position and momentum, to become the transitionary flow between something and nothing.
I then put myself and the box inside the quantum trolley, on the tracks, and on the side as an observer, at the same time (but only if nobody is watching). All my separate possibility phantoms may or may not pull the lever at the exact moment the trolley hits a quantum eraser.
If performed correctly, reality suffers an overflow error and the collective consciousness of the universe experiences what us humans would refer to as a aneurism.
As a part of automatic regenerative attempts to repair such devastating damage to the concept of causality, a series of tachyons are released at the epicenter of the incident causing a level-4∆ retroactive recalibration event. Boom, The quantum trolley never existed in the first place.
