So in the 7th dimension, every one of the infinite amount of universes (on the line) has it's own 6 dimensions below, and then there are infinite versions of 0d, 1d, 2d, 3d, 4d, 5d and 6d ????

@BearWindAppleyard Since 0D is a point of indeterminate size, you can choose to think of it as being infinitely big or infinitesimally small, or any place between. The "point" in the seventh dimension can be thought of a position within the multiverse landscape - so moving to a different position within the seventh dimension and above is moving to a different universe with different physical laws. So yes, that new position defines new unique versions of the dimensions below, just as ours does.

@10thdim So in one of the universes 0d can be a plane and 4d can be a point???

[10thdim]

@BearWindAppleyard 0d is a point. Can't make a line, a plane, or a cube (etc) if all you have is a point.

But a point can be one of the positions within any of the spatial dimensions. A point can be at position x on a 1D line, or position x,y on a 2D plane, or position x,y,z within a 3D space... this is how a point could encompass a dimension (by thinking of it as being infinitely large), or could be infinitesimally small. Then it's easy to think about other points in a particular dimension.

@10thdim It's when we get to the 7th dimension I find it tricky. "Every universe will have it's own expressions of the first 6 dimensions" I think was your words. Let me know if I'm right: the 6 dimensions are basically the same in all the universes through 7d. 0d=a point, 1d=length, 2d=width, 3d=depth, 4d=time (as a line), 5d=all posible (time)lines 6d=all possible and "imposible" lines. But these dimensions look totally deffirent in the other universes?

[10thdim]

@BearWindAppleyard Good question. A 2D plane will still be a 2D plane, a 3D space will still be a 3D space, and so on. But what occupies each of those dimensions could be similar to our universe but would more likely be very different. By the time you're in a universe with a different value for gravity, for instance, the way the underlying information becomes reality will be completely different from the universe you and I are in.

Thanks for writing!

One thing you have forgot to consider is that thought, or your capacity to imagine, is dependent on your past experiences and ideas as raw materials. You could easily imagine a bear juggling flaming chipmunks on a unicycle but if you have never heard of or seen a bear before your mind cannot complete that image. The 10th dimension as I understand it already emcompasses all forms and ideas past present and future, possible and impossible to our multiverse.

I want this video on my D611 phone.

Your video is a favorite on Laos

Video is dated for September 28, 2008, but it was uploaded September 25, 2008?????????????

@aliensnow Your age has little to do with it.

@finalfantasy8911 Well, you just need two dimensions to make a a dynamic universe. 1 spatial and 1 "time(al)"

[Thatguywiththelaptop]

Can't... handle... VIDEO!! *head explodes*

[jamafrican657]

@zentonil An internal anthropic way of looking at the same problem.........

How likely is it that more than 4 dimensions exist? Can a universe exist and function without more than 4 dimensions?
