Suppose you are traveling towards a clock.
Would you not see that clock move faster, because you are traveling through the light it emits?
it will only appear faster when you are also moving at the speed of light, in which case the clock will appear to be running twice as fast
any speed slower than light will appear normal because light speed is a universal constant, theres only non-light speed and light-speed
>>7975188
Unless you are traveling at like a quarter the speed of light(that's a random number) the effects would be so minuscule they wouldn't matter.
>>7975191
what?
Relativity says that it should appear slower. But with the thought experiment in the OP it would be faster. Which is it?
Interstellar says fifth demensional beings can climb time (the fifth dimension) like a mountain or a valley, but what is at the bottom of the valley?
Wouldnt the bottom of the valley be indestructable since that would be the beginning of time and if they climbed down that far wouldnt they explode from the big bang energy?
I would of thought that fifth dimensional beings would just have the ability to phase into locations in three dimensional space time like we can phase in and out of 2D objects.
Doesnt this not make sense?
And why didnt he get noodled by the giant black hole? And also a black hole that big wouldnt it take ages to reach and then pass through the evidence horizon?
They fixed the black hole to make it easier for Coop to travel to the core.
i mean if they could just hack 3D space whenever they wanted, why not just hack away earth's problems?
instead they forced them to go and live on a cylinder for the rest of time
Maybe time doesn't have a beginning? Just infinite cycles.
Also I think he didn't get noodled because the teseract or whatever they call it was on the event horizon?
What's the most efficient way to learn multitudes of different, unrelated things?
I want to learn a new maths, languages, to play guitar, to be able to sketch, program a computer, etc.
then do it and stop being a little bitch posting about it on the internet instead
>>7974603
OP here, with some additional info.
Like (I'd hope) most of you I keep pretty busy in the daytime with school and work, but I have around 2 hours of free time in the mornings and evenings.
Would it be best to do an A-B style of pattern, where on day A I study maths and a language, as an example, for an hour each, then the next day do guitar and sketching and repeat?
Just a thought to clarify what I'm asking here.. Trying to figure out how to do this using as little time as possible and maximum retention of what I learned..
Maybe 24 hours is too long, and I should reduce my list of things I want to learn right now (as in only the "A" day), or maybe I could as much as an A-B-C-D split, and learn even more.
Hopefully anons get the jist of what I'm trying to ask here. Any advice to structuring a routine or schedule would be SPLENDID.
>>7974613
It's not that I'm not - it's that I'm going about in an unstructured manner and I think adding a logical structure would be very beneficial.
Sorry I forgot my trigger warnings
Why is the day length of Mars so closely similar to Earth's? The outer gas giants rotate very rapidly by comparison while the other two rocky planets rotate very slowly. Also the Martian axial tilt is about the same as Earth's. Was Mars also impacted in the ancient past by a large planetoid? Why doesn't Mars have a big moon like Earth then?
>>7974508
Mars was clearly designed by God to be our second home.

>>7974601
You mean like clouds?
How do we know that stars/galaxies are redshifted? What lets us know that they should be more blue in the first place?
We know what the spectrum of a star should look like based on fundamental physics. For example, hydrogen absorbs light at specific frequencies, so these are well-defined "holes" in the emission spectrum of the sun. That alone provides a very precise measure for how red or blue shifted a source is. The fact that it correlates perfectly with the dozen or so other methods confirms it's not some other effect.
>>7974059
>expecting a flat earther to accept the scientific consensus on star spectrums
>>7974059
What if only our sun has this specific chemcial composition and all other stars are made up of completely different stuff we've never even discovered yet?
Why doesn't the electron fall on the proton? Every book just avoids the issue with "m-muh lowest possible orbital" that doesn't explain anything.
Its like how the earth doesnt fall to the sun. I just don't understand why when it reaches 0 Kelvin it doesn't fall to proton
It has to do with the strength of the EM field. If it were stronger then the electrom would orbit closer.

SOUP /SCI/ what was your definition of compactness? / define a compact set in your own words; feel free to define other terms as you please.
Example:
Definition: A set [math]E[/math] is [math]compact[/math] iff, for every family of sets [math]{G_α}_(α \in A)[/math] of *open* sets such that [math]E \subset \bigcap_(α \in A)G_α[/math], there is a finite set [math] {α_1, ..., α_n} \subset A[/math] such that [math]E /subset (/bigcup^n)_(i=1)G_α[/math]
A point is connected to a point if there is a path (obviously continuous) that connects them.
A connected set is a set where every point in it is connected to all other points of the set.
Inuitive and a rigorous definition in almost all contexts
A set [math]S[/math] is compact if and only if every sequence [math]s:\mathbb{N}\to S[/math] has a subsequential limit in [math] S[/math]
>>7973281
I think I like this the path-connected definition of connectedness the most
Any open cover has a finite subcover.
>>7973291
Sequential compactness (the definition you gave) isn't equivalent to compactness in general topological spaces (only in metric spaces).
Anyone here been to a math competition? I'm about to go to one and I don't know what to expect.
I went to one. I got dead last. It was very humbling because I considered myself decent at math.
Fucking Chinese kids lol
yup I did, it was 100 other schools, basic shit, shittiest team, 2 fucking stupid girls on my team. GG WP we lost, they never listened to me.
How do you even study for one? Do I just study everything up until and including DifEq? I am interested in joining one at my school but am not that great at maths.
Is helium exit tank suicide really painless.
If yes, why? Asphyxiation usually is a process of much sufferings. Does it have to do with helium being noble?
I am planning on exiting next weekend.
I fucked up my everything for myself financially, and my degree is a meme (cause my uni's a meme).
Please tell me if it's really fast and painless.
>>7971090
It should be. I'm also trying it, too.
t. physics student
>>7971086
It's not a regular asphyxiation. You are replacing air with an inert gas.
See, the thing is that your body cannot sense a loss of oxygen, only an increase of co2, which you are expelling via the constant flow of the exit bag.
Bored?
Why not watch a 9 minute video of a guy explaning the conditions at the launch pad during liftoff of a Saturn V during the Apollo 11 project (the one that first took humans to the Moon). The elapsed time is 30 seconds. It's pretty cool to see is slow-mo.

At what point does high IQ become detrimental? At 160 IQ for example (some people here claim to have this) people are complete social retards without fail. I've never seen an actual smart person not be autistic as fuck.
>>7975492
thats a monkey you silly cunt
John von Neumann had both a 1-in-100-years intellect (IQ >> 200) as well as an eiditic memory better than Kim Peek's, and he had no social abnormalities.
He actually hosted house parties almost every week and told lots of funny jokes.
If we eliminate the fact that higher IQ people can earn more money than lower IQ people then in today's society IQ becomes detrimental at about 85.
This is a bit philosophical, but I need to ask the science crowd.
I can't just "not think about it"
How do men of science and logic deal with the knowledge of the massive cosmic scale, the possibility that countless universes could be expanding,ending and beginning alongside us, dimensions beyond our comprehension or perception and the cosmic wonder all about us that we will never grasp. And how minuscule and pointless we are. Why does anything matter?
I feel like there should be something more. Like we're missing a puzzle piece
I'm so curious about things I will never experience or really be able to comprehend.
And in the end it doesn't matter if I ever do understand time, or space, or any of it.
Because I'll die.
What's the point.
I was raised to be kind and loving and good, because that's what god wanted.
Why would anything ever matter.
How can we even perceive this existence.
I desperately hope that "god" exists.
I hope that god is some strange cosmological entity In dimensions beyond our comprehension. Misinterpreted and misunderstood. Maybe an alien. Maybe I'm a simulation, being tested for the next round in some computer.
I just hope that when I die, time doesn't stop for me. Or if it does, I want to know now.
Does this keep anyone else up at night?
>>7975275
your other thread is still up - and will be for the better part of 24 hours even if no one bumps it - spaz
cause people long ago realised this and to stop mindless chaos they invented god
now we have a reason for existing and a reason not to do whatever we want
someone smart once said
"i dont fear death because i been dead a lot longer than alive so it cant be that bad"
just think when you die you'll go back to being what you were for the 14 billion years before u was born
on that scale you were never really alive in the first plase
Is chemistry the easiest subject from the hard sciences?
its the one with much knowledge by heart ... except simple anorganics.
it goes like this: maths>physics>Chem>bio
