# Thread: Humans: 10 dimensional beings?

1. The universe we live in determines how many dimensions we exist in.

If we live in a ten dimensional universe, we must be 10 dimensional beings. However, the length we would extend into the higher dimensions would be minimal. For example, a 2 dimensional creature residing in a 3 dimensional universe would have a length, width, and if you looked closely a small height. It would be similar to a piece of paper. The length and width of the paper are easily measurable, while the height would be extremely small and not easily measurable. If the paper had only a length, width, and no height, it would not exist in a 3 dimensional universe.

Therefore, if we live in a universe with 10 spatial dimensions, we must be 10 dimensional beings.

I do not think that your argument is valid for three reasons:
1. It seems that your assumption and your conclusion are the same statement. That is circular reasoning.
2. An object with 2 spatial dimensions in a 3D universe would still be an object with the same number of spatial dimensions. If an object has width, depth and height (which are all measurable), then it is not a two-dimensional object.
3. Is an Universe with 10 spatial dimensions a viable model?

I do not think that your argument is valid for two reasons:
1. It seems that your assumption and your conclusion are the same statement. You might want to refrain from circular reasoning.
2. Is an Universe with 10 spatial dimensions a viable model?
1. I was just about to point that out haha.
2. I think he's referring to string theory which afaik has no empirical support what so ever.

Why?

For example, a 2 dimensional creature residing in a 3 dimensional universe would have a length, width, and if you looked closely a small height. It would be similar to a piece of paper.
If it did have a height (of ANY size) then it wouldn't be a 2D creature: by definition.

The length and width of the paper are easily measurable, while the height would be extremely small and not easily measurable. If the paper had only a length, width, and no height, it would not exist in a 3 dimensional universe.
Therefore, if we live in a universe with 10 spatial dimensions, we must be 10 dimensional beings.
Well so far you haven't supported your claim.

6. I apologize, I was not clear in my post. What I mean is that a 2 dimensional object cannot exist in a 3 dimensional universe, it must have the same number of spatial dimensions as the universe it resides in. This is because in a 3 dimensional universe an object with a length, width, and no height, would have no mass, therefore it must extend into the third dimension to exist as matter.

Also all of my ideas are completely my own. However, I was inspired by a claim saying that the universe we live in could have higher dimensions.

Yes, but that does not take away the circular reasoning you have presented in your O.P.

It might be true that there are additional spatial dimensions that are part of the Universe,
but it is necessary to demonstrate that this idea has any scientific support, otherwise it remains an assumption that becomes a conclusion.

I suppose that you are familiar with the work of Rob Bryanton, who made a YouTube-channel about these ideas?
If you are not, feel free to watch this: Imagining 10 Dimensions - the Movie - YouTube

8. If we live in a 10 dimensional universe then

1) Dimensions have physical reality.
2) We would experience 10 dimensions.

Reality has however many dimensions we say it has, as long as those dimensions are meaningful and not an excuse to make up nonsense.

What Just is saying makes sense, he might not be coming across as clearly as he intends to, but he's not claiming or supposing anything that isn't obvious. The problem is the specificity of 10 dimensions, but that's beside the point made here. It's the same thing as saying "If the universe is 3 dimensional (no more, no less, a point of fact), then everything in the universe is 3 dimensional."
