It is impossible for any object to be infinitely far away from me (or you, or anything else).
Want me to prove it?
If there is an object that is infinitely far away from me that means that the object in question must be at a location that is an infinite number of feet (or meters or whatever). If it exists at all it can't be infinitely far away from me.
The universe is most likely finite. The multiverse is most likely infinite.
>>8908069
did someone tell you the universe was infinite?
the observable universe, everywhere that is causally connected to us by virtue of the limitation on the speed of the transmission of information, is finite but expanding exponentially. Beyond that horizon is an unknown.
>>8908069
And yeah, I guess all notions of "feet" or "meters" lose their meaning when you consider the chaos and infinitude of possibility that allowed for the laws that govern THIS particular universe to spontaneously arise.
Math seems like the most worthwhile degree, applicable to everything in life. If I'm wrong, what's better?
>>8908063

>>8908063
Worthwhile in what way? There are much better degrees for return on investment. EE has plenty of real life application and has nice pay too.
>>8908084
You can't apply EE like you can with math. I want to make a lot of money, obviously, and I don't see how working as an electrical engineer would make me a lot of money. Maybe I'm wrong.
Explain why you hate popsci
>>8908062
It seeks to entertain rather than inform and educate.
mah sex junk is so, oh oh oh
>>8908062
It makes brainlets feel as if they are intellectually superior and arrogant towards to me and their colleagues, despite having very little knowledge of science or proofs.
It also gives people the confidence to publicly speak about topics they know extremely little about and thereby likely spreading false information.
Also, because being smart should not be "trendy".
Is the order of operations arbitrary?
>>8907999
Yes, in physics we call them the canonical order of operations.
>>8907999
Yes, if we changed the order we'd just need to write the equations in a different order (lol) but the underlying logic is the same in any base system/order of operations/language etc.
Because math is discovered not invented

I haven't been to a university because I'm not paying 50k annually to have socialist "professors" tell me that I should feel bad for being white. That being said, I've done my own personal research into dark energy and it's pretty obvious why it's false.
The universe isn't expanding, because if it started out small, why can't we see the light from the beginning of the universe? Furthermore, since the speed of light can't be measured, you can't expressly state that there's a mathematical way to calculate how far away these respective bodies are. So the fundamental basis of dark energy is false.
Go ahead and call me a racist or dumbass; it's amazing to watch pseudoscientist liberals cry and scream when presented with evidence.
>>8907956
oh it's cool that you didn't go to university and decided to learn yourself
which books did you use for modern physics?
Why are there so many dumbass crossboarders
But it's undeniable that, as a white person, you have an advantage due to the fact that your white ancestors subjugated people of color. The truth might be unpleasant but that doesn't make it wrong.

Why anyone takes these clowns seriously?
>>8907846
You can solve any problem which models the observable world with only real numbers. Real numbers should be renamed to observable numbers or something like that, ever since we have gotten into meme science and quantum mechanics.
Perhaps all numbers should be real numbers. Instead of being a real number line, it should be a real number plane.
I don't think we can use imaginary numbers if they aren't real
>>8907860
"Real number" concept is also questionable, if you look at axioms they use to define reals, some of the axioms are just made up to make it work as they wanted.

>egg 3 hard boiled eggs the first day

>egg 3 fried eggs for dinner the next day
>still hungry
>egg an 3 egg omelette for dinner the third day

WTF? Explain this!
feeling hungry is not a quantitative measurement and sample size of 1 is not significant, therefore not scientific and your thread is gay
>>8907801
You do realize a typical omelette has more than just eggs, right?
>>8907829
Except the catalyst are the same
All 3 recipes are made with just 3 eggs.
Hey, so I have a physics test coming up, and I've been having trouble solving shit lmao. Can someone explain how I'm supposed to solve this shit? I've tried but I didn't get the same answer. Shouldn't the angle be negative considering that the force of the 3.00 microcoulombs on the 6.00 microcoulombs is larger?
>>8907768

Why isn't set theory taught from middle school to high school?
it has cleared up so many things for me and i've only watched a few videos on the subject.
>>8907683
Set theory is bullshit, watch Wildberger videos instead
>>8907683
set theory satisfies the urge to grasp at something, at least for a bit. but that's really it.
well you learn to use zorn's lemma which is useful
>>8907683
Because current basic education isn't geared for STEM students since most people are incapable of entering a highly academic field. Instead you are taught what you need to know to function as a normie. Sure a middleschooler could learn set theory, but it probably isn't going to be relevant in their lives.
But what if it's real...
>>8907529
Then we're well on our way to inter-galactic colonization.
>>8907529
It doesn't, so don't worry about it.
>>8907541
They're gonna put it in space.
I know that doesn't really mean anything on its own, but people are willing to drop a half-million to shoot this junk into space and see if it actually does the thing with reasonable confidence.
Hi /sci/,
I'm currently working on a hard-ish science fiction series, in which most of humanity lives in Lagrange point colonies, à la Gundam.
Realistically, what would the transit time of orbit-to-orbit spaceships moving between Lagrange points be?
I was originally envisioning somewhere between a few days to a few weeks depending on how much mass they're hauling/Hohmann trajectories. Would that require unrealistically wimpy engines?
In universe, radiation-free He3 reactors are mass-produced and the government has speed/performance/Delta-V restrictions on ships operating within the "earth sphere".
>>8907434
Bump. I was thinking of using Jeb'd Fusion NTRs or some flavor of Ion drive for intercolonial ships.
Without doing any calculations, let me tell you that the ISS orbits the planet once every 90 minutes or so. Start with that as a ballpark, then because you know the radius of low earth orbit and you know the radius of Lagrange points, you can use geometry to find the ratio of the two circumferences.
Huh. Interesting exercise. I assume you're moving between L4 and L5, as they are the two points of stable equilibrium, thus most likely to have permanent stations. So there are two ways to do that (fuel- efficiently). Assuming you want to go from L5 to 4, you have to either decrease the orbital period of the ship so it catches up to the point ahead, or increase your period so so the L4 point "laps" you.
In both cases, you have to fire your engines twice: once to leave L5 to the new orbit, again to adjust orbital speed once you arrive at L4 back to circular orbit.
Either way, you're looking at something on the scale of a month (lunar orbit).
The other method would be to fire your engines a few times: to drop your orbit (decrease orbital period), speed up again to head towards L4 with excessive energy, then again at L4 to slow way the heck down, depending on your hurry. A few days? But transporting fuel is extremely expensive, so I'm guessing you'd go the long route.
Oh - and of course the converse is true if you go from 4 to 5.
please vette this for me /sci/... I don't know matrix math, but this seems not correct, animooted.
>>8907378
it is correct tho
There's no point in knowing how to do this because computers are the only things that do these calculations in practice. Matrices aren't even used in real math.
>>8907407
t. faggot who has never taken an upper division math class
numerical matrix multiplication is only the very last fucking step, after you've already solved the problem and you're plugging in the specific initial conditions into your solution. You'll fucking NEVER get to that point if you don't know how the basic operations work.
If people didn't bother learning this stuff you can throw out 99.9999% of modern physics, astronomy, economics, etc
neet here !trying to changing his life around going to attend community college in the fall.
don't wanna disappoint my parents more by getting some useless degree. so i was thinking of trying engineering
if anybody is majoring or has a job with it. could you recommend me a beginners book i could read? and explain to me whats the material like in school?
i know its math heavy but i feel like if i dedicate 6-8 hours a day this summer on learning i'll be rdy by fall.
thanks so much !

Neet thinking he can devote 6-8 hours of his life to actually working in just a day. That's like asking someone who is obese to run a half marathon tomorrow. Nice try but you're going to give up or burn out really quickly. Just set a time and each day spend 1 hour doing pomodoro. When you feel better about continuing then aim for 2 hours, then 3 etc. Good luck on turning your life around but be smart and stick to it. Discipline is the bridge between your goals and achievements.
t. Was a NEET now about to enter med school.

please don't. there are enough engineers already.
I was wondering how an alien species would view humans if the aliens have a bias like us meaning they would see their species as "people" as humans as animals basically.
Is their evidence to show that humans show a bias towards their species in general?
>>8907281
I would shoot a chimp to save a doggo so no
>>8907281
Humans look down on animals and see them as inferior because we cannot verify that animals have any sense of intelligence since they have solved nothing?
>>8907281
it has to do with more than how close you are imo
if rats could talk, we'd love them and feel closer to them than to chimps
a human doesn't REALLY have a species radar, but we do pattern recognition
animals are similar - remember the guy that joined the wolf pack? it's about what you do, how you act
if aliens came and they could learn a human language and talk to us and have a similar civilization/lifestyle we'd feel very much closer to them than to our cousins the chimps
