Can you clarify this?

Post by -Fongstar- on Sun Sep 19, 2010 2:18 am

Okay today my cousin said that his teacher told him that there is no such thing as a straight line Shocked
He said that a straight line always ends back in the same spot that makes no sense scratch
like a circle.
My other cousins were criticizing him about it lol!
Is there such thing as a straight line?
what i think is that CHS is teaching him bullshit!
What is Dark matter?

Here's what Wiki says about dark matter:

In astronomy and cosmology, dark matter is matter that is inferred to exist from gravitational effects on visible matter and background radiation, but is undetectable by emitted or scattered electromagnetic radiation.

As far as a straight line..that might depend on how long the line is and where your drawing it at on earth or in space?

hmm

sounds like elliptic geometry to me, but i'm pretty sure that i'm wrong.

about the line: what topic is this class? physics? math? drawing?
from an actual hands on point of view, in microscopic detail, the line that is drawn straight with a pen is not actually straight, because the ink does not come out in a straight line. however, to the naked eye it seems as a solids straight line. that's one way to think about it.

same logic can apply on a grand scale....like a straight line in terms the wall in your house...it is not fully straight, but rather uneven in microscopic view.

so, in really there is a straight line, but there isn't a PERFECT straight line!

about dark matter, i have never learned about this nor have i had nay interest in the topic, but from initial understanding:
it's a term used to define a mass (which consists of matter) that is not 100% confirmed to exist. to make things clearer, how do you know something exists? -you see it! how can u see something? -light bounces of the surface of this matter (which has mass) and allows us to see the object (its color, shape, size, etc.). in practice, all matter reflects light to show its color. that which doesnt (meaning it absorbs all light) we see as color black. since there is no light in space (its dark lol) then when matter absorbs all light it is black, but since we cant see black in a dark environment (in our case space), we can NOT be sure if the matter actually exists.

this is what i believe is meant when referring to dark matter (matter has mass, but which bears no reflective light/color, and therefore is not visible. and since something is not visible, you cant confirm that it exists, even though it has mass). btw, dark matter is usually used to talk about space and galaxies, etc.
go here for the picture, its the basic comparison:
Dark Matter: Not Dark Matter:
this is my inference into the topic, and a simplified explanation. ask away if u want more!

i think his teacher is talking in a hypothetical situation.

but the thing is, his teacher might not be talking about euclidean geometry. like in euclidean geometry, 2 lines that are parallel never intersect. but in non-euclidean geometry, 2 lines will always intersect, so the lines aren't "straight" i suppose

i believe you are referring to elliptic geometry which deals with spherical planes (not your regular x y coordinate plane lol). in such a case as earth! parallel lines of longitude go around the earth (a sphere) and meet (intersect) at the two poles.

sigh, you guys are bringing back memories of my high school geometry.
P.S. i fuking hate geometry! love all math, but hate geometry lol!

oops, that's what i meant to say. see my original post for that XD

there are 2 types of non-eu geometry i think....

1. elliptical
2. hyperbolic

i see, you did mention it. btw there are more than those two. it's just that they are the most common ones. it all depends on the plane you use (flat, hyperbolic, etc.). all others are just...well.....there lol!
