I want to start this New post, First by Saying I Respect you Thomas, And I fully Respect what you think especially on any physics topic. It's Important for me to get your thoughts on What Theoretically from your point of View a Fifth Dimension would be, I know you are set in your ways, And Empirically, There is no Data to back up String theory.
I Take Empirical Data As a Fact I do, But, I love to theorize, Take this page from Phys.org.
https://phys.org/news/2014-12-universe-dimensions.html This is from 2014, It's based entirely on String theory, And I can't comment on how credible Phys.org truly is. I tend to take them more seriously than some sources. But here is their Rundown, Of speculated Higher dimensions,
These quips are ripped directly from the page itself so the emboldened letters are not me making some point, it came off the page that way.
The
first dimension, as already noted, is that which gives it length (aka. the x-axis). A good description of a one-dimensional object is a straight line, which exists only in terms of length and has no other discernible qualities. Add to it a
second dimension, the y-axis (or height), and you get an object that becomes a 2-dimensional shape (like a square).
The
third dimension involves depth (the z-axis) and gives all objects a sense of the area and a cross-section. The perfect example of this is a cube, which exists in three dimensions and has a length, width, depth, and hence volume. Beyond these three lies the seven dimensions which are not immediately apparent to us, but which can be still be perceived as having a direct effect on the universe and reality as we know it.
Scientists believe that the
fourth dimension is time, which governs the properties of all known matter at any given point. Along with the three other dimensions, knowing an object's position in time is essential to plotting its position in the universe. The other dimensions are where the deeper possibilities come into play, and explaining their interaction with the others is where things get particularly tricky for physicists.
According to Superstring Theory, the fifth and sixth dimensions are where the notion of possible worlds arises. If we could see on through to the
fifth dimension, we would see a world slightly different from our own that would give us a means of measuring the similarity and differences between our world and other possible ones.
In the
sixth, we would see a plane of possible worlds, where we could compare and position all the possible universes that start with the same initial conditions as this one (i.e. the Big Bang). In theory, if you could master the fifth and sixth dimension, you could travel back in time or go to different futures.
In the
seventh dimension, you have access to the possible worlds that start with different initial conditions. Whereas in the fifth and sixth, the initial conditions were the same and subsequent actions were different, here, everything is different from the very beginning of time. The
eighth dimension again gives us a plane of such possible universe histories, each of which begins with different initial conditions and branches out infinitely (hence why they are called infinities).
In the
ninth dimension, we can compare all the possible universe histories, starting with all the different possible laws of physics and initial conditions. In the
tenth and final dimension, we arrive at the point in which everything possible and imaginable is covered. Beyond this, nothing can be imagined by us lowly mortals, which makes it the natural limitation of what we can conceive in terms of dimensions.
I post these things, Not as some sort of contradictory challenge, I Respect what you believe Fully. I know String theory isn't a Subject you Fancy.
To me, These things are just Fun ideas to play with. I would really like your personal thoughts on the concepts of these higher dimensions, Even though, I know you lean opposed in some respects to String theory, What I'm looking for is your thoughts on the properties of these theoretical extra dimensions?
