Alright heres the deal. Let's say we discovered a parallel universe next to our own, the difference is minuscule. We establish a communication with one another.


So here's the question, if you had a chat box with yourself from a parallel universe with almost no difference to our own, could you ever truly communicate and if so how would you break the chain of same messages?

If you close your eyes and meditate, is it possible to break your brain by using your imagination to an extreme degree? I developed something I call forced-dreaming that allows me to enter a dream like state in my imagination from meditation, and I sometimes worry if what I'm doing is dangerous, even though my physical state is otherwise calm? Is it possible to break my sense of reality through some amount of continued imaginative shapings of my mind?

Why do women look like children? A whole lot of traits considered to be attractively feminine are also neotenous traits. Small jaws, soft hairless skins, limited bone protrusions, small muscles. It's the same in terms of behavior, women are more impulsive, more easily socially manipulated, and quick to be swayed by emotions. Was Aristotle right in theorizing that women are just stunted men? Is sexual attraction to women the same as pedophilia?

light
Is the speed of light a logical or fundamental limit?
What I mean by logical limit is this. Consider temperature and the Kelvin scale. Zero Kelvin is the temperature at which matter is completely void of motion and therefore, energy (except for that of its mass?), so going lower than this makes no sense; you can't have less than zero energy.
Is it the same for the speed of light? As I understand it, the speed of light is a proportionality constant between space and time. Relativity tells us that with enough energy, you can technically shorten your travel time arbitrarily, no matter the distance, by approaching the speed of light. But the fact is, to a motionless observer, you can never go faster than the speed of light. Information can never travel between two points in space faster than the speed of light.
So which is it, is the speed of light a logical or fundamental limit? If it is a fundamental limit, doesn't that imply something serious about the universe? Why is the speed the speed of light precisely what it is? Why not 1.1c or 1.254c? Obviously the value changes based on the physical units, but the fact is that it has a definite value. Doesn't this imply that certain choices were made and that the universe was designed?

IQ is right triangle distribution
1591340341875
It is not a bell curve but a right triangle. We know this is true because there are more dumb people than smart people and the average of this right triangle is 100, thus I conclude with certainty that the IQ distribution is a right triangle.
Here is a formal proof:
Most people are right handed
Most people are straight
Most most right handed people must be straight
Since IQ is hereditary and right handedness is also hereditary, we therefore conclude that most people that are right handed and have an IQ are also straight
Create a chart that's axes are perpendicular finite and positive.
Connect the endpoints of the axes with straight line.
The result is a right triangle of IQ distribution

Any criticism of this proof is welcome. If I missed something let me know.

In the movie 2001 a Space Odyssey there is gravity in the spaceship because it is rotating around itself.
What I don't understand is how can something "rotate" in space?
Rotation requires a frame of reference, but what if space was completely empty?
How can you tell that the spaceship is rotating if there's nothing around it?

i don't get what the big deal with quantum entanglement is.
imagine some game of snooker with perfectly elastic balls and no friction. one ball hits two, transfers all its energy and they go off in different directions. now measuring one of the moving balls tells you about the other, because they're linked by the initial impact and energy needs to be conserved.
i must be missing something because entanglement doesn't seem very spooky at all.

What do you think of eon musks argument about our reality being a simulation?

https://www.youtube.com/watch?v=xBKRuI2zHp0:

tldr: He claims that while reality would be a single world, ultra-high-tech games indistuinguishable from reality would allow as many realistic worlds as you desire - you could say for instance that half of the whole "real world" population is playing, and that could be a few billion simulated worlds running at any time. Since such simulations seem to be possible in a near future, an insignificant time lapse from new from evolutionalary point of view (compare how we evolved since pong, then imagine it 10 thousand years from now), it seems plausible that they will exist. So in that scenario, thinking of all perceivable realities, the chances you're perceiving the real world would be 1 in a few billion.

I'd add that its unlikely that since the whole history of mankind, and of life in general, has been pure hell until recently (since living in the wilderness with no food and no shelter, hunted by predators, until not having anesthetics recently) how likely it is that you was born at the point of history where there is maximal material comfort while perfectly-realistic simulations are not ready, but seem right on the corner (that would be the ideal 'game set' to allow immersion - since its almost the lastest you can be so that "we are in a simulation" guess is not THAT good.

And how would you conciliate that with the fact that your life sucks.

Here's a fun little exercise I thought of. The Pythagorean triples are those triples [math](a,b,c)[/math] of positive integers such that [math]a^2 + b^2 = c^2[/math]) Some examples are (3,4,5), (6,8,10), and (5,12,13). In fact there is an infinite amount of these. For convenience we shall always list them such that [math]a < b < c[/math].

If we specifically we look at the ones where the first number is a prime we find an interesting pattern. Let's take a look at the first few!
(3,4,5)
(5,12,13)
(7,24,25)
(11,60,61)
It seems as though if the first number is a prime, then the last number is just one more than the middle one!

Prove this.

I'n so mad the Sun is called the Sun. It's a star, a giant boiling nuclear plant, a space object, we can't call it Sun, or ''Ginger pussy'' or ''Heavenly fireplace'', it should be called smth like Betelgeize, or K7104, etc., more scientific and realistic. Instead we call it Sun and this ruins our lives and perception of reality, in the sense of we take sun as something domestic, habitual, something that we own, we look at it as a warm bright spot rising each day like it's on our service. We don't realize that we're living on a stone flying in the freezing dark abyss, and have this fire ball flying nearby, keeping us warm, and we don't care about it at all, we don't even think about the sun, it's just some boring thing waking us up each day, we look at the sky and say ''uhh fuck, it's gonna rain again'' while there's an endless universe behind that layer of clouds, and we crawl on this stone covered with rotting organics and do our primitive routine. I'm so tired of this false culture we're living in, thinking everything around us is our farmland from some fairy tale and we are hobbits on it. Is this what we came to after thousands of years of philosophy and science? Do you realize that we are still living with a primate's consciousness, in the era of ''sticks and stones'', messing in the mud and filth as a bunch of worms and bugs. Our present reality can be compared to the one that Sentinel savages are living in today, complete disgrace, while above us in space there is and absolute ''modern'', finite futuristic reality, that we are able to make our habitat by using our brain's potential to full extent.

Sad pepe
I'm somewhat concerned about my abilities in math lately. I'm a physics student and over the summer I've begun studying to maintain my knowledge from last semester. However, I keep running into difficulties of many kinds. Firstly, I make stupid math mistakes. Like kindergarten stuff. To begin my summer studying I started with khan academy, doing some simple average rate of change questions. I kept doing things like saying that 32-8 is equal to 16. It was so strange. I'm pretty sure it's just because I'm not focused. I haven't really dedicated myself to studying and I only just started today so it's natural that I'd be out of it. It put me off though.

Secondly, I'm still struggling with concepts from years ago. Geometry for example. Khan academy asked me to find the maximum area of an isosceles triangle. I had no idea where to start, largely because I don't know what an isosceles triangle is.

In essence I'm asking: Would it be best for me to go back and study my high school fundamentals first and then move on to calculus when I'm ready or should I keep going and hope to pick those old skills up along the way?

witten
Witten's daughter is trying to get an award named after the great statistician Ronald Fisher renamed/removed because he held some strong views on race. I don't think Witten should be /ourguy/ any longer.

Where does this sort of thing end? I wonder how much of SJW activism can be explained by its practitioners being failures in academia/arts/whatever, and on some level realizing they lack what it takes to make a meaningful contribution, so they resort to political advocacy in order to satisfy their need for status and attention.

Floating Islands
ocean
Why hasn't man conquered the seas yet? I mean like massive, floating continents. I know the oceans are one hell of a beast but is it possible to build a floating structure so large it would be inpervious to capsizing? Keep in mind the benefits of the sea:

Less disease/insects
Unlimited power due to currents
Unlimited source of purifiable water
Good source of food if you suppliment it with farming
Less pollution

Other than the obvious starting, engineering and maintenance costs (salt water corrodes like a bitch) am I missing something there? Seems like a huge untapped resource to me.

Debunking Grandi's series
math
https://www.youtube.com/watch?v=PCu_BNNI5x4&t=

Supposedly Grandi's series proves that 0=1/2 and people use that as proof that the universe can come out of nothing. Here's why that is false: The problem is within the sequence itself, supposedly

S=1-1+1-1+1-1..... repeat forever

Grandi makes the assumption that this S sequence equals 0 but that's not the case when you realize that S can also be written as

S=0+0+0+0+0.....

Which can in turn be written as

S=0*∞

0*∞ does not equal 0, It's undefined

The Limit of Technology
s-curve
The solution to the "Fermi Paradox" is simple - there exists a hard upper limit of feasible technology that no species can ever get past regardless of effort. The laws of physics preclude a greater degree of control over matter/material to allow for the higher realms of technology that sci-fi fantasizes about. Something being "theoretically possible" DOES NOT MEAN THAT IT IS EVER ACTUALLY POSSIBLE - and that's assuming the technology actually is even theoretically possible in the first place.

The universe is teeming with intelligent lifeforms. They also max out at the "upper limit" of technology, which is slightly more advanced than where humans are now.
Human's are going to hit the wall within the next 5 to 15 years.

Pick related is a famous S-Curve. Singularity people and others like it believe that we're just now at the foot of the curve, and we're about to hit a great exponential increase up. But they are wrong. The past 150 years of the industrial revolution WAS the exponential increase when you look at human civilization as a whole and we are already curving off at the top of the graph. This is it.

Some anons will seethe and cope at this post. Just wait for 10 years and you will be forced to accept the reality of the Universe.

Even in the worst nuclear winter our planet is still 1 billion times preferable to mars colonization.

I don't understand how chris langan is wrong
christopher-langan
He is so often mocked but after actually reading his Cognitive-Theoretical Model of the Universe, it makes a lot of sense to me. Essentially the universe is meta-darwinian, constantly evolving and learning more about itself, self-determining its course.

https://pdfs.semanticscholar.org/537a/c9c6066f20039491a72b361a4009a3d5623f.pdf

>But there is another possibility after all: self-determinacy.

>The CTMU has a meta-Darwinian message: the universe evolves by hological self-replication and
self-selection. Furthermore, because the universe is natural, its self-selection amounts to a
cosmic form of natural selection. But by the nature of this selection process, it also bears
description as intelligent self-design (the universe is “intelligent” because this is precisely what it
must be in order to solve the problem of self-selection, the master-problem in terms of which lesser problems are necessarily formulated). This is unsurprising, for intelligence itself is a natural phenomenon that could never have emerged in humans and animals were it not already a latent property of the medium of emergence. An object does not displace its medium, but
embodies it and thus serves as an expression of its underlying syntactic properties. What is far more surprising, and far more disappointing, is the ideological conflict to which this has led. It seems that one group likes the term “intelligent” but is indifferent or hostile to the term “natural”, while the other likes “natural” but abhors “intelligent”. In some strange way, the whole controversy seems to hinge on terminology.

Interpreting Equations
MCAT-ECAT-Physics-Formulas-page-001
I've struggled with how to answer this question ever since I was an undergraduate so maybe I'll get /sci/'s opinion.

Consider a few simple equations, like F=ma or V=IR for a moment. What is the "right" way to interpret the casual relationship between the quantities in these equations?

Take V=IR for example. Does a voltage difference across a conductor cause a current to flow, or does current flowing through a conductor cause a voltage difference? In the case of F=ma, one could ask if a force causes an acceleration or vice versa.

Does it even make sense to talk about one quantity "causing" the other? Or is it that neither quantity "causes" the other, and instead voltage, current and resistance are perfectly correlated in a manner such that V always equals IR (for an ohmic conductor).

More generally, do the physical quantities in any given equation actually influence one another, or are they merely perfectly correlated (for an exact equation)?

Personally I prefer to think that they are just correlated, as a causal relationship implies one quantity "happened" first, which doesn't make a whole lot of sense. But I am open to alternate interpretations.

Does varying levels of intelligence imply we can all be retarded, or is there a non-arbitrary IQ at which we "understand" how "things really are." Basically, if ayy lmaos visited us, what are the chances that we would be on the same plane of intelligence, instead of being akin to dribbling little babies with our "higher math" and "scientific method?" Can you imagine the ayys having functioning "technology" that people could not ever understand?

Are we nothing but what we pay attention to? Attention is the direct link to what grows our brains network (IE all we are). Our brains networks are in conflict with each other constantly to get our attention in order to grow.

We can only do 7 conscious processes IE attention at one time.

>With the future climate instability already locked into the system by recent human activity we will most likely return to the climate volatility of the Pleistocene. Climate change will adversely affect agriculture in a number of ways including sea level rise, higher average temperatures, heat extremes, changes in rainfall patterns, and the loss of pollinators. Less understood changes include the effects on agricultural pests, soil composition, and the growth response of crops to rising CO2 levels.

This is a stupid question but I am slightly confused about the wording about this.

>Show that if a set S has cardinality m, where m is a positive integer, then there is a one-to-one correspondence between S and the set {1,2,3,...,m}.

By this do they mean that there exists a function [math] f [/math] such that [math] f: S \rightarrow {1,2,3,...,m} [/math] is a bijection?

Because surely not all functions from S to {1,2,3,...,m} will be bijections because all the domain elements can just map to a single element for example f(x) = 1 for all values of x in S...

Am I understanding this correctly?

Is it possible for Asians or Whites from normal families to get into elite schools?
harvard
By elite schools I mostly mean Harvard, Princeton, MIT and Stanford.
I feel like the bar for white or Asian students is so high that it's almost impossible to get in. Unless you're the valedictorian of a highly prestigious high school or you are genuine prodigy, excellent academics still won't get you accepted. For students from very rich families it's a different story. You can hire people who know how to game the system. You can get SAT tutors and hire professionals to write your essay. Your family can donate large sums to the school. Your can do progressive sounding extracurriculars like "I'm a VP at a charity(that my dad owns)" or "I teach students in undeserved inner city schools how to [insert something esoteric and somewhat academic]". If someone in your family are a celebrity or politician you are way more likely to get in. If you are associated with a tragedy you are more likely to get in(see David Hogg). Legacy students have an unfair and absurd advantage for being accepted.
Ultimately, what this means is that after of seats are taken by affirmative action and the children from wealthy families, it is impossible for whites or Asians from normal families to get in unless they are a one in a million prodigy. Bill Gates and Mark Zuckerberg were basically prodigies, however their families', although not rich, were still upper class. What upsets me most is that admissions will be way more impressed by some BS progressive sounding extracurricular rather than, for example, you worked a part time job to help your family. Rant over.
