/sci/ - Science & Math

yes, retard. who told you it wasn't?

>>11292999
for graphing purposes in the 3rd dimension it is, in irl no

>>11293000
stfu simpleton, go back to eating crayons

>>11292999
If we live in the 3rd dimension, then the 4th dimension is not time since we experience it, although in a very linear fashion

>>11292999
4th dimension is our state of mind

>>11293029
you can't troll me if you're dumber than me

>>11293029

>has never heard of a worldline before
Do you even into relativity?

>>11293055
but you are a moron so that problem is solved

>>11293058
>he thinks space time is a real thing (pic related)

>>11293061
i dont have a brainlet wojak that can quite encompass the depths of your retardation, but you should know that your trollery is obvious. habeeb it!

>>11293066
literally you. you donkey brained half wit

>>11292999
4th dimension is subjective experience plane.

>>11292999
I didn't know dimensions had assigned ordinals. Which one is energy, 8? What about spin?

>>11293102
Back to /x/ you go.

>>11292999
No, that's retarded.

>>11293201
>>11293119

literally where the hell are you people coming from? is this the absolute state of /sci/ right now?

>>11292999
It's not for the following reasons
-time is not commutative
-time is a scalar
-time is not independent from space

its motion, time doesn´t exist

>>11292999
By some dude's definition yes

>>11293956
>time is not independent from space
This meme has to die, stop spreading psued donkery

>>11292999
if is a physical dimension, (like up, left etc.), it may be different than the others, you can go left and right, up and dow, but you can't go to the past or future with a move, also you cant be in somewhere and not somewen, so I think it is 4 dimention, but we can't understand it yet as 3d creatures.

>>11293035
... We live in the 3rd spacial dimension. The idea is that time is something like just more space in actuality and that what we experience is just an illusion of being in said space.

>>11292999
It depends.

>>11293034
very nice

bump

I imagine 4th dimension as a 3d heatmap

>>11292999
time does not behave as a spatial dimension as the hilbertian norm has a signature (3,1) because of time : $ \sqrt{ x^2 + y^2 + z^3 - c^2 t^2} $

>>11296094
soz
[math] \sqrt{ x^2 + y^2 + z^3 - c^2 t^2} [/math]

>Retards? On my 4channel™?
I'm honestly impressed that this place has the active userbase that it does considering how shit tier it is compared to other /sci/ forums.

show me where in the universe time and dimensions physically exist

>>11292999
No

>>11296099
Name one good forum

>>11296108
>Scientific realism
Get off this board

>>11294075

>>11296108
That's a category error.

>>11294313
is that cat autistic?

>>11293844
You're defending the frogposting trolls and retards?

>>11292999
when you mail any package
they need to know
WxHxD and WEIGHT

1st dimension = line
2nd dimension = dots form 2d planes when stacked together
3rd dimension = 2d planes form 3d sphere when stacked together

4th dim = 3d spheres stacked together in a line(like how a movie or animation is a bunch of pictures bundled together that changes over time as it plays) one single straight timeline.

5th dimension = a bunch of 3d lines together forms 4d plane(multiple timelines branching out)

6th dimension = branching possible timelines form 5d spheres.

Rinse and repeat

>>11298246
this is not the correct way to explain spacetime to people

The "dimension" you're talking about describe the amount of information you would need to find something if you entered the system, and is NOT the physical description of time.

For example, I am super intelligent AI from another universe, and I want to find timmy who lives in a 1D universe. In order to find him I need one point of information, how far he is on the line, in order to find him. In our universe you would need four points of information, the basic 3 spacial dimensions (assuming a reference point is possible to find natively) and a 1 dimension of "when" to find him.

What you posted is purely a thought experiment and does not matter when describing relativity or spacetime to someone

>>11296099
What other /sci/s do you recommend?

there is only 3 dimensions

>>11296126
still waiting

>>11298246
Why you explaining the obvious?

>>11298563
I'm curious too, surely there are good alternatives.

>>11292999
The 4th dimension is black hole cosmic hollow earth chemtrails that faked the moon landing vaccines and also the moon is fake too because nazi UFOs secret Antarctic base one world government. /x/ told me so.

>>11299738
he seems dumb

No u

>It depends.
the pseudointellectual nonanswer of nonanswers. It depends on what?

>>11293035
we live in 3 dimensions but we are sliding through space at a pretty constant speed and direction, overall.

>>11294313
>fags actually think this is what the future will be like

>>11292999
I don't believe in time

>>11293844
I think it's a joke
