If black holes are such a cluster fuck of what the fuck, why doesnt it just consume the universe all at once given it's "properties"?
Is it possible black holes arent actually "holes" just extremely dim balls with extremely dense mass and high gravity? maybe rather than it consuming anything it's simply just destroying/ripping apart particles that get sucked near it?

Matter cannot be created nor destroyed by a physical or chemical reaction.
Don't you think the entire world community of astrophysicists who devote their entire lives into studying things like this would have already thought of this? The existing definition for black holes is backed by countless hours of research.
What you just proposed a black hole "might be" is pop science bullshit you literally made up in maybe 5 minutes. Fuckoff...

>why doesnt it just consume the universe all at once given it's "properties"?
You can do better than that. First give us your explanation for why something having counter-intuitive properties instantly destroys the universe.

I really want to see a black hole
its shit because it's pretty much just the entrance to hogwarts

Why do animals need to sleep but cells, fish and trees don't?
>>7637914
Dawwwww, he better adopt that kitteh :3
>>7637914
>animals need to sleep
>but fish don't
Fish are animals senpai.
>>7637974
Then why don't they require sleep?
ok guys, I love videogames, they're cool shit you can program your computer to do and I don't mean your average /v/ garbage.
I think games are cool software.
Anyway, I came here asking if you guys know about cool CS and math topics or just science topics that would make interesting videogames.
I want to know at least how to make my own cellular automata, what book should I read?
I'm self taugh and barely knows more advanced math than high school algebra, but I'm willing to learn.
Maybe making a game about how political ideologies...

Do you know of any good game of life multiplayer game? The ones I checked weren't that good. I wish there was some kind of RTS multiplayer game of life.
>>7637809
An extremely complex, text based with some visual graphics, diplomacy/political climate simulator. You start off as one country, could be our world, could also be a randomly generated one to keep things interesting, but that increases the overall complexity by huge margins, so stay on Earth for now. I guess your goal is to become the richest and most powerful country or something.
>>7637925
I've made one (for 2 players)
in fact, I changed the rules of the game of life because I though it creates to few alive cells and too many dead ones.
give me a moment, I have to search where I've written the rules and translate them in english...
What does /sci/ think of common core?
gives me autism every time i see one of those pictures
Good intentions, retarded execution. Yes we should teach kids to think and abstract with maths, not only crunch numbers. But teaching kids to abstract arithmetic ina different way is fucking retarded when the problem is with the curriculum itself.
Stop with this pragmatic obsession of mathematics and start showing what mathematicians actually do. Make mathematics an enjoyable and engaging class with basic proofs, challenges, interesting theorems and a constructivist approach to math. Literally start with the Greeks and go building many subjects until calculus.

Getting into game programming question
So there's a certain project in its early stages that aims to recreate my favorite game. I feel very strongly about supporting it and i assume programmers are the most in demand for it.
It will be using C++ with SDL 2.0 and OpenGL.
As a total beginner aside from knowing what code is, what should i start learning? C++, obviously. But specifics for game dev? Prerequisites?
I can google and have been but i don't want to be that guy replying to a question like this with "just don't do it the...

Java and then just learn some basic engines.
Let's say I have a simple system
a + b - c = 0
a > 0
b > 0
c > 0
and let's say that I'm 'blinded'--meaning that I can't explicitly take any two values and perform anything other than an equality comparison (this means that I can't compute piece-wise or branching functions, nor can I explicitly check for x > y).
If somebody gives me three example points a, b, c, is there any way I can determine whether my system is satisfied? I had originally thought to attempt to derive a single system of equalities...

No clue what the hell you are talking about. What do you mean by three example points.
>>7637790
Say I have a hypothesis of a = 1, b = 2, c = 3.
I want to be able to verify that the above example points satisfy my system without the use of branching, piece-wise functions, or comparison operators other than = or !=.
>>7637922
Okay, I think I see what your saying. So your elements don't start off positive, you have to prove they are positive, correct?
If so that's clearly impossible. You haven't defined a way to show anything is greater than anything, since you have ruled out using standard methods.
You need to have an axiom that says, "We know x>y when [some quality] is satisfied." And you don't have that.
Sure, you can find a lot of counterarguments, but this is the only thing that makes sense. Questions like "What are electrons made of? What is bigger than the universe?" can be answered by that. Everything kind of loops on itself, the world is a recursion. Our universe is a substance on someone else's planet which is an electron inside a substance and so on.
Yes, I do know about electronic orbitals and how electrons don't just spin around the core, but if we start researching it, we would probably find and explanation.
Fuck, lost the thread name, "atoms are solar systems"
Atom are not solar systems, theres no star in the middle of an atom.
people this stupid exist
just why
Would it be possible to make a supersonic propellor aircraft? Let's say that no more than 10 percent of the usable thrust comes from the exhaust.
>>7637623
I was about the mention the Tu-95, but you already have it posted in the image.
It seems like it would be possible. Just take a Tu-95 and add more engines.
>>7637634
I know there was a american turbo prop fighter that could have hit mach .95, but stability problems ruined it. I think it also got like 30 percent of its thrust from jet exhaust.
>>7637642
This thing got abandoned because it was too loud and incredibly unstable. The tips of the propellers exceeded mach 1 and the sonic booms became unbearably loud.
Double major in CS and Math is better than Acturary and Math?

Get a pure math degree, why bother with anything else?
1st year University student here. Thinking of changing my Course from Biochemistry to Zoology. It is something I'm much more interested in, and the majority of my classes this semester have been the same so transferring would be simple.
Was wondering how screwed I would be in the long run with such a specialised degree compared to Biochemistry. Are jobs in that field just non-existant? Has anyone any experience in the field?
>>7637503
I'm in your same situation
molecular biology and thinking of switching to zoology/ecology related stuff
do what makes you happy, anon
>>7637503
You're not there to get an education, you're there to get a job.
You do not work a job for fun, you work a job for money.
Just get a degree in biochem, and play it safe. We're not baby boomers, we actually have to compete for our jobs.
>>7637503
If you want a job you'll find one, you can always write a book about Africa fauna
Physical science isn't about examining reality. Reality is beyond our grasp. It exists, but we perceive it with imprecision. Since what most people call reality (the physical space we see around us) is in fact an image of reality within our brain, by examining it we're not examining reality but only our perception of it. In other words, physical science is about exploring interaction of human brain (which is capable of self reference) with other physical objects.
Am I my brain?
>>7637334
youre roughly 2500 years late with that idea but yes, thats true. doesnt really matter though, since we cant do anything about it.
>>7637334
Then why does my color blind friends disagree with me about which colors are which? There must be some objective reality that both of our brains can interpret differently.

I'm an idiot, so take my idea with a grain of salt, but I've played with magnets before and if you hold them in just the right position they will be forced away from each other.
Why not make a "road and floating car" where they have these opposing magnets that force the car to stay floating off of the ground? From there, propelling a floating car that isn't being affected by its own weight or friction. Hell, you could still even use wheels and it would be more efficient since most of the weight of the car would be nullified by the magnets pushing...

They have done this, with electromagnets. They are called MagLev trains.
>>7637309
why not use this technology for the rest of us? At least, on a much smaller scale.

Expensive as fuck, no one will give two shits about it.
For all things related to nuclear power.
Discussion topic of the day: Should we be building new nuclear capacity alongside renewables, or instead of them?
>>7637298
Focus on nuclear power, renewable energy is pretty much a joke compared to nuk.
>>7637298
I've heard that fusion power could run on seawater, using heavy water as fuel. It would only create helium (a useful resource in itself), and could last for a very long time (thousands of years, I think; long enough to find a replacement or leave the planet).
Is this reasonable, assuming we can get fusion to work, or is the an oversimplification?
>>7637314
That's the gist of it really - the main assumption there is that we can get a working commercial reactor at all. But if we can, it's effectively a renewable resource (I think that it's more than just thousands of years, but don't quote me on that).
