Why do we see the dimensions of our universe as 3 dimensions of space and time instead of space, time, and matter? (Or another variation)
In what way do you think matter is, or even could be, a dimension? What is your sense of what the word dimension even means?Jeffrey phalen said:Why do we see the dimensions of our universe as 3 dimensions of space and time instead of space, time, and matter? (Or another variation)
Well a dimension to me would be the various parts of what something is made of. Space is made of height, width, and depth. Time is hard to explain for me but I understand the concept. I see how we group the two together, but that would also imply that matter is a byproduct of space and time. I guess the way I am looking at it right now electromagnetics sprout from matter and precieved in space over time.phinds said:In what way do you think matter is, or even could be, a dimension?

Have you even done any research at all on what a dimension is or are you just deciding that you can make up your own definition?Jeffrey phalen said:Well a dimension to me would be the various parts of what something is made of.
No, space is not "made" of anything. Space is just geometry. H, W, and D are just ways of measuring things IN space.Space is made of height, width, and depth.
No, it would not.Time is hard to explain for me but I understand the concept. I see how we group the two together, but that would also imply that matter is a byproduct of space and time.
and in what way does that make matter a dimension?I guess the way I am looking at it right now electromagnetics sprout from matter and precieved in space over time.
This is not an answer, I'm just using your premise to try to count things...Jeffrey phalen said:Why do we see the dimensions of our universe as 3 dimensions of space and time instead of space, time, and matter? (Or another variation)
I guess I'm thinking of it more atomically whenDennisN said:This is not an answer, I'm just using your premise to try to count things...
Hmmm...
Space (height): 1 meter + 1 meter = 2 meters
Space (width): 1 meter + 1 meter = 2 meters
Space (depth): 1 meter + 1 meter = 2 meters
Time: 1 second + 1 second = 2 seconds
All ok and fine. And now...
Matter: 1 orange + 1 apple = ehh, what, 2 fruits?
(or 1 electron + 1 proton = what? 2 matter particles? What's the use of counting in this way, I wonder?)
I cannot argue with that, I guess I'm just realizing my class fully focuses on what and not why.phinds said:Have you even done any research at all on what a dimension is or are you just deciding that you can make up your own definition?

No, it would not.

Jeffrey, in physics you can't(*) just make up your own definitions of things, you need to get straight on what standard terminology means.
* Well, you CAN, but it will not end well

Hi again, @Jeffrey phalen, and here is a page regarding basic physical units (in mechanics):russ_watters said:it sounds like you are still in school. this should help:

In short though, dimensions describe locations/distances/sizes of objects.
Mass is a property of objects, not a dimension.
The 3 dimensions of space are length, width, and height. These dimensions allow us to describe the physical size and shape of objects in our universe.
Time is considered the 4th dimension in our universe. It is often described as the progression of events from the past, through the present, and into the future. Time is intertwined with the other 3 dimensions of space, as it affects the movement and position of objects.
The theory of relativity, proposed by Albert Einstein, states that the laws of physics are the same for all observers in uniform motion. This means that the laws of space and time are relative, and can change depending on the perspective of the observer. The theory of relativity helps explain how the 3 dimensions of space and time are interconnected and how they affect the movement of objects.
While we can mathematically describe and understand more than 3 dimensions, it is currently believed that we can only experience and perceive 3 dimensions of space and 1 dimension of time. This is due to limitations of our senses and the physical laws of our universe.
Our understanding of the 3 dimensions of space and time has evolved greatly over time. Early civilizations believed in a flat Earth and a linear concept of time. However, through scientific discoveries and advancements, we now know that our universe is much more complex and multi-dimensional. The theories of relativity and quantum mechanics have greatly expanded our understanding of the 3 dimensions of space and time.
