Neutron = 2 electrons + 2 positrons
Their mass-energy comes from the relativistic speeds of the leptons, which interact only minimally using EM force, since the field lines undergo lorentz contraction.
It's leptons all the way down.
You really expect me to believe this very convenient explanation that there was just a big explosion that created everything?
Is there anyone where who performed the nofap experiment this year?
If so, what do you think the results of your experiment were?
Do they help to prove or disprove the nofap theory?
my daughter has to make a 20 minutes oral
presentation about maths as her final high school exam and she asked me for some fun ideas but since I'm a retard I'm asking you
(her physics presentation will be about molecular cuisine)
why is this?
it's like saying that a hill was fine tuned to enable a ball to roll down it.
regardless of what physical laws ended up being, it seems reasonable to assume that if life is capable of emerging from them, then it would.
is it even an interesting question to ask? shit is the way it is because of the way the universe is. a creature without a nose doesn't ask about the smell of a rose.
we only know of one way that life works. and it's within the rules laid out by the one universe we observe, by necessity.
how can we say that if the properties of the universe were different that some other form of life wouldn't emerge instead? or any other manner of shit that isn't possible here but might be possible there?

It can't be for dental health because low IQ people will not be smart enough to care for their teeth properly, they will lack the foresight to do so and/or lack the brainpower to do a good job of it.
The only reasonable explanation seems to be that its done to intentionally reduce people's intelligence. What other reason would make sense?
Will living and adapting to colder environment help with maintaining a resistance to cold, which will have cryogenic effects and help with aging? Greenland sharks are known to live up to hundred of years, is it because of adapting to the freezing climate? So if I start living in iceland, and stay in the cold water for a longer periods of time freezing my balls, without causing hypothermia, will the actual resistance build over time, minimazing aging and actually help living longer?

I mean why try to solve the problem when you can just deny the most undeniable aspect of reality? What am I missing?
What exactly is intelligence? Is it learning speed? Is it the quantity of how much you memorize? Is it the ability to concentrate? Is it reaction time? What makes you think a paper with a number score can accurately measure something as complex as intelligence? How do you describe the fact that many supposed geniuses can believe obvious lies and supposed idiots that are able to see through these obvious lies?
There are some gifted with incredible memory where they can literally describe everyday of their life with such detail, or have incredible photographic memory where they can be at a helicopter, see the city once, then able to draw that city. IQ tests are psuedoscience with no confirmed merit of truth unless proven otherwise.
>Ether exists, not a "preferred frame" of reference but a medium that produces relativity as an emergent property
>Ether is always trying to return to equilibrium, all 4 forces arise from that
>Time dilation is just means it takes more energy to return you to equilibrium, waves propagate slower
>Length contraction is just ether resistance at high speeds
>Big bang wasn't the creation, it was just a disturbance that has propagated. IE things outside observable universe
>Relativistic mass is just extra ether distortion when moving fast or spinning (aka frame dragging, magnetism are the same thing) no different from normal mass
>“Spin” is simply the shape of the disturbance in the ether
>"Electrons" are literally just semi-stable energy propagations in the ether, kek
>"Quarks" are just non-stable shapes that make up larger stable shapes (protons, neutrons)
>Dark Matter is just gravitational hotspots created from interference between wave patterns in non-spherical systems (galaxies, clusters)
>Gravity is 1/r in equilibrium (2 star system), 1/r^2 in most places and higher than that in hyper clustered areas
>Protons are just high density compression, electrons rarified intensity

Now that its know that vegans are unhealthy, can science explain why are vegans so unhealthy?
Should vegans be forced to eat meat in order to have a healthier overall population?
We already vaccinate people in order to make the population healthier so enforcing a healthy diet seems like a logical net step.

Why aren't you nolifing your MS paint drawings all over 4chan, anon? You too could brainwash millions of retarded lemmings into adopting whatever memes and vernacular you want, purely by means of astroturfing, to the point where literal politicians and famous people start using it like the dumb cattle they are. Even the people who resist yoyr memes will cave in and submit to them once all their friends and peers start using them, so they'll cuck into using your meme to fit in. Its literally so easy, so why aren't you doing it?
And to make this thread /sci/ related, what are the long term societal and structural consequences of being able to program millions of people just by dedicating yourself to neurotically spamming the same memes over and over again repetitively?
What were the big events of 2024 on /sci/? What were the best threads? What were the best new science memes? What was the biggest or most surprising science news of this year?
Here are a few examples to get us started:
The Nature of Dark Matter and Dark Energy: Together, they make up 95% of the universe, but we still don't know what they really are.
What Happened Before the Big Bang?: Was there "something" before spacetime as we know it? If so, what was it?
The Fine-Tuning Problem: Why do the fundamental constants of the universe seem so perfectly calibrated for life?
The Information Paradox of Black Holes: Does information really get destroyed in a black hole? How do black holes work at a quantum level?
The Ultimate Fate of the Universe: Will it end in a Big Freeze, Big Crunch, or Big Rip? Could it even be cyclical?
Those are just a few examples, but there’s so much more to explore.
What blows your mind about cosmology? Let’s discuss the biggest questions and share theories!

>Data from ground measurements indicate that the downward (backward) radiation of the atmosphere shows indeed full saturation of the IR CO2 bands and does not support noticeable additional Thermal Forcing (TF) by increasing CO2 in the lower atmosphere… we can expect full saturation already at current concentrations.
This recent paper gives a good explanation of absorption limits and specifically for absorption limits for CO2, it might be of interest to the overwhelming majority of people who never studied enough physics to be able to run through the absorption limit calculation on their own, this includes pretty much everyone who didn't get a PhD in physics with a strong focus on the propagation of radiation.

Cold temperature record from 1940 broken in Manitoba
https://winnipeg.ctvnews.ca/cold-temperature-record-from-1940-broken-in-manitoba-1.7144635
Manitoba’s cold weather broke several temperature records in different communities on Thursday, including one that had been in place since the 1940s.
According to a weather summary from Environment and Climate Change Canada (ECCC), four communities in Manitoba set new records for cold temperatures.
The coldest? The Roblin area reported a temperature of -37.1 C on Thursday. The old record was -35.5 C, which was set in 2000.
The Pilot Mound area reported a temperature of -34.3 C, down from the previous record of -33.9 C set in 1940.
Even for Canadian weather this cold in unprecedented and has never been experienced before.

is this coincidence or is there a deeper meaning to this?
For example, why wouldn’t a terrorist get a bunch of weather balloons and attach them to timed detonators that pop the balloon automatically after a few minutes or hours and then attach a bowling ball to them? So there would just be random 16-20 lb bowling balls falling over a mile high at a terminal velocity near 600 mph. Someone would not have to be very bright to do this, yet they could easily get away with it. There are many other plots I can come up with off the top of my head, yet I never see them on the news at all. Why is this? If even one out of a thousand people were crazy enough to do this, society would collapse overnight. Are people just good?

How true is this?
But I think CO2 is the least of our problems. It is completely reversible, just stop it for a while and it will be completely absorbed by the plants. What isn't reversible is the dozens of other ways we are destroying the environment by dumping trash and toxic waste, destroying natural habitats, etc.
Just look at some maps of forest area that doesn't exist anymore, do you really think a few extra degrees of temperature is going to destroy more environment area than that? Why do we never hear anything about this? Is there a reason the media and the governments only care about "carbon credits" and other bullshit?
Is the term "side effects" in terms of medicine just a less dangerous sounding euphemism for poisoning that was developed in order to help scientists make more money selling poison?
Is there any way to use science to independently verify them?

1. What does a sine/cosine function do with the numbers you are giving it? What happens in this blackbox?
2. How does the function need only a single parameter if you need the opposite and the hypothenuse to calculate it?
3. How does this all relate to circles? I know that the sine function outputs a wave that looks like half a circle, but I don't understand how it all relates to that.

I dropped out of high school long time ago and now as NEET, I'm trying to understand some math to feel better about my uneducated self. I hope you guys are patient with me.
how does this make sense? wouldn't its mass still hold it together? where does the explosion come from?
This is from Galileo Galilei of all people, for fucks sake. This is a huge hole for me in his authorship, other than him composing a line out of points for some reason, even though Euclid's first definition exists.
(also he should have used Euclid III.36 to define where that line was tangent to the circle, as AC, AG should be equal to the square on AE)
If no one is able to help me, it wouldn't surprise me, as no one actually knows anything about actual physics or astrophysics on here.
i was trying to relate this to calculus. And, another thing, lets call "V" the approximation of our universe to the universe called "other side". This V is inversely proportional to the thickening (so, with more thickening, less V, less approximation of the universes). This thickening can be measured with percentage with the letter k, where an membrane that are ABSOLUTELY thick will have 100% of thickening (k=100%), and an membrane that are ABSOLUTELY thin will have 0% of thickening (k=0%). With that, i was trying to relate the k with the V, remembering that with less thickening k and V increases.
Do you guys have any idea?
