The first two items are the answer for the question...

There are infinite things that aren't a perfect straight line, so you can't say not straight (or bent) is the opposite of straight (they are opposite just in gramatic but not in mathematic).

Again what I'm saying is that in logic you can 't have one thing opposite to all else that isn't it... opposition is binary. Like the method to prove something is right is like proving that all else is wrong (won't enter the details, but it basically is proving by negative).

 

Sine wave is the way human can use to explain (or model) the things in nature. It doesn't necessarily mimic the phenomenom.

if you put phase 180 degrees for sine you still get sine. cosine is the 90 degree phase of sine. So they aren't exactly opposites, you could use them as they are binary in opposition. Now you see the difference?

The cold/hot opposition per example... it really is amount of heat and how you perceive... so 0k or absolute zero (would be your coolest point) is the "total absence of heat" while we still don't know what is the maximum existing heat as far as I'm aware to have the 2 opposites, altough they wouldn't be opposite, just the 2 extremes of a scale.


"There are infinite things that aren't a perfect straight line"

you mean like exponential increase?

 

"if you put phase 180 degrees for sine you still get sine"

yes its still a sine wave but due to displacement its the opposite of the original which is why why have technology like noise cancellation 

waves that are exactly out of phase are used to cancel the sound waves that are unwanted when someone is listening to music

sure the two sets of waves have the same shape ( like with the sine example ) but they are different/opposite in the sense that they are out of phase which is why they cancel

 

" while we still don't know what is the maximum existing heat as far as I'm aware to have the 2 opposites, altough they wouldn't be opposite, just the 2 extremes of a scale."

 

that is a good point its true that increasing heat and increasing lack of heat don't proportionally rise to two exact opposites because i think at some point as you said a point is reached where 0k is reached so molecules stop moving while we don't know as of yet what the hottest temperature possible is

but wait hold on i'm sure that i've heard of a substance going down past zero kelvin before

oh yeah here

http://www.livescience.com/25959-atoms-colder-than-absolute-zero.html

but still you have a point there its just that this is something that i'm honestly seeing everywhere 

even politics with the left and right, on the left people that want more and more control being imposed while the right wants the opposite less control more freedom


Exponential curve is something that isn't a straigth line (but there are also another infinite forms that aren't a straight line) so you can't say exponential or any other curve is the opposite of straight just because they aren't straight.

Just because two waves can cancel each other that doesn't mean they are opposite, cosine isn't the opposite of sine altough you could say they are if they are in the same phase...but as you know no one would say cosine wave, it's always sine wave plus phase. So it would be silly to say the opposite of sine wave is a 90 degree phase sine wave don't you think? But they would still cancell each other (they have opposite signal in their magnitude, but they aren't opposite things).

You can't increase lack of heat, as there isn't "COLD" in physics, there is just more or less heat.

And on the link you said I'll read it... but it could only mean that 273,15C was the wrong absolute zero. Like time, temperature have no sense being put in a negative scale when you have an absolute zero as minimum point... but sure we could create the VGC temp scale that would have it's zero at the middle point of absolute zero and absolute maximum (whatever it may end up being, maybe 1Million K) and then we would be close to -499.750 degrees VGC at the moment. But having the 0 on the middle wouldn't make the extremes of the scale opposites...

Things in nature aren't necessarily opposites, it's just that for human brains the concept of opposite is easier to understand.
