Click For Summary
Dimension plays a critical role in understanding supersymmetry and gravity, as it influences the unification of fundamental forces. Supersymmetry requires extra dimensions to function, which are explored through theoretical models like string theory and M-theory. The metric, or measurement of distance, is essential in understanding gravity's effects, particularly how gravity alters the reference points in space-time. In supergravity, extra dimensions are believed to cause gravity to appear weaker compared to other forces by allowing it to "leak" into our three-dimensional world. Overall, the interplay between dimension, supersymmetry, and gravity remains a significant area of research in physics.

IN a Flash it Can all be explained?

Currently we see unification only in supersymmetry? If this is the case how would dimension speak to this? I have been thinking about Gravity a lot, and the strength and weakness seem to me, to be only a matter of dimensional significance? What is the Function of the Metric, and from gravity to supergravity how is this explained?

On a flat brane world with no gravity you have one point from to measure? Yet when it comes to supergravity this point is no more? So have we not define the difference between, and should we not call that dimension gravity?

ange,

The concept of dimension is a fundamental aspect of our understanding of the universe. It is a measure of the space that a particular object or system occupies, and it is crucial in understanding the laws of physics and how they operate in different situations. The concept of dimension has been studied and developed by scientists for centuries, and it continues to be a topic of great interest and research.

Dimension is arrived at through a combination of theoretical modeling and experimental evidence. Theoretical models, such as string theory and M-theory, propose the existence of extra dimensions beyond the three spatial dimensions that we experience in our everyday lives. These models are then tested and refined through experiments, such as the Large Hadron Collider (LHC) at CERN, which can potentially provide evidence for the existence of these extra dimensions.

Currently, the most widely accepted theory that unifies all the fundamental forces of nature is supersymmetry. This theory proposes that for every known particle, there exists a corresponding superpartner particle. However, this theory requires the existence of extra dimensions in order to work. This is where the concept of dimension comes into play in relation to supersymmetry.

The function of the metric, or the measurement of distance, also becomes crucial in understanding the effects of gravity. In a flat brane world with no gravity, there is only one point to measure from. However, in the presence of gravity, this point is no longer a fixed reference, as the curvature of space-time caused by gravity can change the distance between objects. This is where the concept of dimension and the understanding of gravity become intertwined.

In the context of supergravity, the extra dimensions play a crucial role in explaining the strength and weakness of gravity. It is believed that the extra dimensions provide a way for gravity to "leak" into our three-dimensional world, making it appear weaker than the other fundamental forces. This is a key aspect of supersymmetry and the unification of all the forces of nature.

In conclusion, the concept of dimension is a complex and multi-faceted one, and its role in understanding the laws of physics, especially in the context of supersymmetry and gravity, is crucial. The arrival at the concept of dimension is a result of both theoretical modeling and experimental evidence, and it continues to be a topic of great interest and research in the scientific community.
 
I thought I would start a thread, as as spinoff to perhaps highlight and contemplate of that the ideas in the paper mitchell porter pointed to means. I just started to sniff it.. and wrote in the other thread "How to fix Relativistic QM so it's consistent?" Indeed fixing relativity and how to understnad equivalences, seems to be the central issue of the below paper. ----------------------------------------------------------------- Huge paper, I havent ready it through fully but skimmed...
