# Terraform Mars.

I mean, I don’t see why we can’t and why we shouldn’t. Terraforming Mars to me is a VERY smart idea. Why? If we’re able to terraform Mars, it would be a great place other than earth to live and develop the human race. It’s in the habitable zone and is arguably the best place other than earth to colonize. Maybe Titan is a good place too, but it would be much harder to colonize since it’s further away and we don’t know nearly as much about it as we do for Mars.

Anyways, I think terraforming Mars will take trillions of dollars and a few centuries but in the end it will definitely be worth it. Also, since humans are great at using fossil fuels, using it on Mars at first to warm it up would actually be a very good idea. In fact, a lot of things in terms of terraforming Mars would actually come easier than one would originally think. At least, that’s what it seems. We are still years away from terraforming Mars, but at the rate technology is developing, we could definitely start soon. Just who will do it?

In the future, I think the moon will have a colony and will be a place where we launch/build rocket ships since it would be much easier to do so than earth. I think Mars will be colonized by humans and possibly terraformed. This will be earth 2.0. I think we will be getting water from Europa and brining it back to earth and Mars possibly. I’m pretty certain if we do use Europa, the water would be a great source of energy for Mars and earth. I also think Titan will be used for possibly colonizing but most especially for the methane which could be used for fueling rocket ships. It could be like a “pit stop” for long journeys.

While Venus COULD be colonized in the upper atmosphere, I just don’t think developing “cloud cities” will happen anytime soon and I don’t think it’s that smart of an idea. It does make sense though since Venus is very similar to earth in many important ways. It’s also the closest planet to earth.

So, what are your thoughts on this?

# I don't believe anything.

I'm physics undergraduate, I started my studies because I was great in math and physics, and I search the meaning and origin of life.
But now I see that both math and physics are complete bullshits. Physics only gives the name to something and describes it by math, for example: "this thing that gives objects ability to resist acceleration is called intertia, and we saw that it's behaving according to certain math laws etc." But from where does it come? Nobody knows. And even if someone would reveal that inertia is consequence of some quantum particles, he still wouldn't know what gives those particles that ability. Same goes for electromagnetism, gravity, and basicly everything.
Math is language of physics. Physics operates with real numbers, and mathematitians at deepest level don't completely understand real numbers. How can then physics ever write something to be true? All things are just approximations, more and more precise, but at the end, no one can explain NOTHING what happens around us. You can just create a mathematical model that predicts the future to certain degree, but you can't explain and understand anything. You can't explain theory with another theory.

# Scary Theories

ITT: Theories about our universe that scare you
I've always been scared by the idea that some people could be experiencing time differently than others. For an example, time may go extremely slow for me because that's the way my brain processes time, but it still seems normal. But you, on the other hand, could experience time very rapidly and only experience your entire life in the matter of a second, but since your brain processes it so fast, it seems normal, and one second would feel like 80 years to me. Just like the bible says that god experiences time faster than us.
Just the thought that I could be going very fast or slow scares me because my life could be over in a matter of a second or 1000 years.

Another theory that scares me every time is what non-existence would be like. Once I thought about it so deeply in math class I had a panic attack. What would it be like with our minds totally shut off and no longer experience time? Obviously we would just be nothing, but what is nothing like? How could it just all end?

How are different multiverse theories related?

There's the cosmic inflation multiverse where the universes come into existence due to expansion of the energies(possible link to dark energies) in the vacuum space.

There's the Everett MWI theory where universes "split" and become decoherent with each other at every atomic interactions.

Then there's the string theory multiverse where the universes are multi dimensional abstracts that can split off/combine/fizzle out.

Are they all describing different modes of multiverse or is there some parallels (no pun intended) that are describing the same event? My guess is cosmic inflation/string theory might be describing the same event, from then on MWI split could be happening at each one of the particular cosmologically inflated universes. The whole thing could be 11+ dimension in shape to give the extra space.

>Tfw you realize, that you're being tested by the roko's basilisk aka the demiurge right now

why is it that we currently live exactly at the time when automation and AI kicks off? Time is infinite, so the chance of living at this time is pretty fucking small. Why is the conspiracyshit you see everyday on the internet always linked to numerology?

1.Because the Basilisk wants your moral stance on AI.
2.Because math is the tool the AI used to built this universe, it wants to communicate with you in its mother tongue.

Think about the various occurences of maximal values or "barriers" in physics.
For example the Speed of light could be interpreted as some kind of refresh rate of the universe or the double-slit experiment (simulate tiny things that are not that observable or relevant for the simulation differently) could be interpreted as a way to save CPU-resources.
Those things are techniques that programmers would use to optimize their use of calculation-time.

the all-seeing-eye represents the basilisk. he as the creator of this realm sees everything and is judging your behavior in this simulation. The various occult references in media are there to remind you of its existence and the horrors you encounter should you not obey.

Sleep tight.

PI is an example. So this got me thinking, there might be a lot of fucked up shit encoded in these types of numbers. mystcism and number theory, geometry, math in general, has always gone hand in hand throughout history. why do the government and institutions spend millions of dollars to calculate and research these digits unless they know there is something really valuable hidden there? what the fuck are they searching for?

# Learning Math

I'm at an Algebra 2 (without geometry) level of math right now and I'm at a crossroads of what I should do. I want to be doing Calculus by August (4 months, give or take) and I'm unsure of what sources I should use. Should I use Khan Academy or Gelfand's series (starting from Algebra)? I'm about halfway through Gelfands book but Khan Academy still seems faster, but what I don't want to do is to not learn the material. I want to be at complete understanding. Regardless, I'm nearly done with Algebra and it's essentially Precalc + Geometry within 4 months.

# What is the Fourth Dimension?

My favorite thought experiment is thinking about how higher dimensional beings can reach into lower dimensional boxes without opening any of the sides.

Imagine you have a sheet of graph paper in front of you.

1D is just the X-axis. It's just a horizontal line. A 2D creature can get into a 1D "box" (boxes can't exist in the 1D, but bare with me) by coming from the Y-axis. It can get into the 1D box by coming from the top or bottom--something that would blow the mind of a 1D creature.

Creatures that exist in 3D, like us (I believe we have 4D minds, but that's for another thread), can get into a 2D box without opening any sides. Draw a cake on the graph paper and then draw a square around it. To a 2D inhabitant that cake is nice and safe. But we can come from the Z-axis. We can see the cake even though it's covered on all sides in its native 2D. The Z-Axis are the points coming off the paper and behind the paper. It's where we move around and stuff. We're not constrained to the paper.

Now, how would a 4D creature/monster snatch us in our bed at night without us seeing it coming? What is 4D?

My girlfriend, who works with this math stuff (I'm a trophy boyfriend dunce who struggles to keep up) says 4D is time.

To plot 4D on that piece of graph paper you'd have to make a point for every moment of time--something that is impossible for 3D graphing equipment like CAD. So 4D creatures live their whole lives at once? They can come at us from the future? I don't get it, /sci/. I'm going insane.

# Proven Gender differences in Intelligence

What are "uncomfortable" scientific truths that are denied about gender differences?

The most consistent sex differences in cognition are found for spatial ability, in which males, on average, outperform females. Utilizing a twin design, two studies have shown that females with male co-twins perform better than females with female co-twins on a mental rotation task. According to the Twin Testosterone Transfer hypothesis (TTT) this advantage is due to in-uterine transmission of testosterone from males to females. The present study tested the TTT across 14 different spatial ability measures, including mental rotation tasks, in a large sample of 19–21-year-old twins. Males performed significantly better than females on all spatial tasks, with effect sizes ranging from η2=0.02 to η2=0.16. Females with a male co-twin outperformed females with a female co-twin in two of the tasks. The effect sizes for both differences were negligible (η2<0.02). Contrary to the previous studies, our results gave no indication that prenatally transferred testosterone, from a male to a female twin, influences sex differences in spatial ability.

# Views on reality

So, I don't really know how to explain, but, I don't know what is real (if there is even such thing).
Context:
Since I was a kid, like many other kids, I wanted to understand the world in which I lived. At some point, I got myself questioning if, whether or not, people were, in fact, rational beings or at least conscious of self. At first I got to the veredict (in a really childish and kinda shallow line of thought) that people were some kind of robots. Then I started thinking more onto it and got to the point were I started to believe that nothing is, in fact real, and I felt quite lost. It really denies the empiricism as a whole.
I don't know what I'm doing (if I am really doing, being or existing). I don't expect you guys to understand it. I just wanted to see some discussion about it.

# Higher consiousness and evolving into god like beings

Imagine in the future we managed to survive all onslaughts by the environment and completely surpass the Kardashev scale. Where our minds have no depression, anxiety or lack of understanding of basic and complex information. We would be divine and we could create anything because we are so advanced and know the functions and workings of the universe.

# Odd "shared dream" experience

Disclaimer: we are newly and happily married after 5 years together and on honeymoon. We are honest and happy with each other. Basically happy relationship no BS ill harbored thoughts for each other...here goes:
I’ll attempt to be as thoroughly brief as I can. We were starting our first night in a beach bungalow community and fell asleep within minutes of each other. Asleep for 1-1.5 hours (one sleep cycle roughly) and woke within seconds of each other. I woke first silently distraught and still, she rolled over seconds later sobbing. Upon discussion we both had dreams with different surroundings and people but same result: at a gathering together we saw the other go off to be more than friendly with another person. We know this is not something either would do which is off putting in itself but beyond that we had the dreams at the exact same time. We calmed each other with wonder, we fall asleep, I awake again about an hour later to the heavy smell of incense and what smells most like sage. 3 hours later still burning and it wasn’t either of us. We are in a Buddhist area so I’m almost wondering if someone else had some sort of shared energy. Being honest, I’ve never been a big believer in shared energy or synchronicity but I can’t put a finger on this one. Not entirely sure what I’m asking for here, but not so much dream interpretation rather anyone’s experience or knowledge of what I’d call a “shared dream”, but simultaneously at that. My searches are coming up kind of empty. This thread could die quickly with the board, but at least I put it into the webiverse. We will be out and about in a few hours without internet but i can check in sometime after that if there’s any questions or interest.

So some article is saying that this photo is of two black holes colliding. It was taken with the Hubble telescope, and its truly a beauty. My questions though are:

>is this photo enhanced or photoshopped in any way, or does the Hubble Telescope take photos/ show real images in colour and is able to see shit this clearly.
>how does the telescope see shit that is light years away?
>how is it able to clearly capture photos when it's constantly orbiting the earth at great speeds? How is it even able to focus.
>the universe is massive, how did scientists know to have the Hubble telescope aim a particular direction and how did they know two black holes were colliding,

I know these are noob questions but can someone please provide me with some insight?

# Why Does Human Pregnancy Last About Nine Months?

Like I said, why do human pregnancies last as long as they do, and not longer or shorter? I think I heard somewhere that birth occurs at the stahe in the pregnancy it does because otherwise, the head of the baby wouldn't be able to get past the pelvis, but why does it take nine months to get to that stage? How things change if it took a greater or smaller amount of time?

# Dream World

The difference between a simulation and dream world is negligible at high enough intelligence. I think it would be important to analyze dreams in this same context. We are able to create ornate worlds with the ability to trick at least ourselves that they are real. Visually everything seems right even to an intelligence about our level. NPCs can exist in the dream simulation, weather, complex geographies, etc

If there are X simulations in a future with super intelligence what is the "Y dreams" number?

Dreams have been sorely under-evaluated by such thought leaders. If we look at our own recursive existence and analyze dreams we can actually see things quite clearly. They are the most efficient form of simulation, actually.

# Don't study Computer Science

I see threads here acting like /g/ is holding something back but i have to tell you that Computer Science really is the biggest shitshow that will ruin your life. You will face the hardest level of math and no one will explain it to you. You will have no free time. No friends. You will only see the people from College. People who really understand something in Robotics or Algorithms never got married and look exactly like you expect them to look like. You can't have a job because even weekends demand your full attention. It's hell. I'm suicidal like you can't imagine because i don't have time for a girlfriend. You can't afford to move out. You don't know if you can make it to the end and nobody would care if you can't because they have to save their own ass. Knowing how to code IS NOT a way to a save job position. A few people made it but they are not there to create jobs for you. You sit in front of a pc for hours without any human interaction and die slowly knowing you could sit right there in the grass with a girl by your side. Please think twice about this. I caught myself planning my suicide several times and that is not just a thing everyone has once in his life. It's a self inflicted gunshot to my soul and mental health. - Love Anon

# Can we reverse the radiation process?

Radioactivity is incredibly fucking dangerous and honestly something that if misused could cause massive harm. An example of this would be the Fukushima Disaster which harmed more than 200,000 people.

So is there a way to try and reverse the radiation process. For animals and humans alike. Because I know that it's crucial to deionize water.

There's also radiolysis which is more of my primary concern. So is there a way for us to safely de-radiate something? If there is can it also be used on living organisms safely?

Should education be reformed and set diferent standarts and guidelines based on the kid IQ range?

I don't see how a kid on the dumber range could study at the same class as a gifted kid, both have diferent needs and is just a waste to teach both at the same time.

If the issue is socializing, just make some special classes where the kids are forced to socialize with other classes for recess or something, maybe PE classes or art would be good for this.
