So I've opened it again, but from this point on any religiously themed post is going to be deleted. Nothing against that discussion, but this thread's topic is on tangible dimensions, not spiritual ones. Read the damn OP.

This thread is being reopened.

As from today until further notice seekn4 has been informed that he is banned from all off topic areas of the forum. If you see him post in any parts of these forums ignore the post and just report it. If you don't do this be warned that any reply you make with him will also be deleted.

This punishment only extends to the non-music forums, he is allowed to post in the music forums. Any members goading him or trying to start things with him into drawing him to post in the areas he is not allowed to post in will also find themselves having action taken against them.

I hope this is clear to you all.

Now do not discuss this post in here, just go back to discussing the original thread topic.

I could only watch three of the videos. One thing that didn't make sense was Carl Sagans retelling of Edwin Abott²s Flatland. If an apple was to pass through a 2D world being 3D it wouldn't see anything it wouldn't be able to kick the square out of the 2D universe and the 2D square couldn't make sense of of a 2D uinverse floating above it. For the apple a 2D universe would be {x,y,0} that means at any or all time it would be looking at nothing! Yes the brain as the organ that comprehends what the eye visualizes it in two dimensions, but that doesn't mean the eye see 2D. Now just apply that to the visual perception of an apple. There would no inforamtion to garner from a 2 plain that had zero height, it doesn't make sense. The story is more or less a thought experiment but not on the same level as one Einstein would performed when he was working on his two theories.

Another possiblity is that we live in a infinite dimensional universe. If one took in consideration Richard Feynman's single-electron hypothesis, There isn't many electrons throught the universe spinning around different nucluei, but maybe one electron with protrons and neutron obitting a single electron but each in its own different dimension. And it just appears to us that the universe is 3D and there are many electrons. Now the downside of this single-election hypothesis is that the purpose of the Large Hadron Collider is to unravel the universe.

The fifth dimension is at right angles to "Space-Time" Which means that there are other versions of time we do not know about, or have not experienced. The simplest way I can explain it to you is to use vertical and horizontal as examples, they are the only dimensions I can explain time to you with right angles.

"One can think of ordinary, real, time as a horizontal line. On the left one has the past and on the right, the future. But there is another kind of time in the vertical direction. This is called imaginary time, because it is not the kind of time we normally experience. But in a sense it is just as real, as what we call real time" Stephen Hawking

Or do not exist.

PoorOldPo

Well it does exist. Just because you cannot comprehend it or experience it subjectively does not mean it does not exist.

Acceptance of one's ignorance to everything is the first step to infinite wisdom old chap. Einstein accepted the existance of the fifth dimension. It took a while but he eventually gave his approval to Theodore Kaluza's proposal that the field equations for gravity and light are resolved for our space time when they are calculated at the fifth dimension. The fifth dimension becomes a medium in which to combine Einstein's theory of relativity with Maxwell's theories on electro-magnetism.

Huh.

It exists as a mathematical concept, it lacks empirical confirmation, and has theoretical difficulties.

Gravity waves would go a long way to confirming it's existence, which they hope to observe soon.

Anything beyond that is seems to be speculation. There a lot of different theories counteracting each other, and every single one has a lot of impressive mathematics (and no doubt youtube videos) behind it.

So maybe I was being more accepting of my ignorance when I added it not really existing as being one of the options. Especially when talking about dimensions BEYOND the aforementioned fifth one.

P A N

super cool. i have no idea what it means. but it sounds SO COOL.

Yeah I think that just because mathematics can explain aspects of reality doesn't mean that everything that exists mathematically is real.
