Discussion Overview

The discussion revolves around the concept of gravity potentially leaking into or from other dimensions, exploring its relative weakness compared to other forces. Participants examine the validity of this theory and its implications within the context of string theory and general relativity.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • One participant suggests that gravity's weakness might be due to it leaking from or into higher or lower dimensions, seeking opinions on the theory's validity.
  • Another participant dismisses the theory as pure supposition without physical basis.
  • A different participant recommends a resource that may clarify the ideas presented, implying that the original statement may be incorrect.
  • One participant recalls reading about the concept of extra dimensions in a magazine or book, indicating some familiarity with the topic.
  • Another participant argues that gravity does not require a complex explanation involving extra dimensions, attributing it to the attraction of matter and the bending of space-time as described by relativity.
  • Some string theorists propose that the weakness of gravity could be explained by the ability of gravitons to traverse dimensions between branes.
  • A participant reiterates the argument against the necessity of extra dimensions for explaining gravity, while also pointing out the contradiction in referencing string theory without acknowledging its multi-dimensional framework.

Areas of Agreement / Disagreement

Participants express differing views on the necessity and validity of involving extra dimensions in the explanation of gravity, with no consensus reached on the theory's acceptance or rejection.

Contextual Notes

Some statements rely on assumptions about the nature of gravity and dimensions, and there are unresolved questions regarding the interpretations of string theory and its implications for gravity.

Okay I'm definitely a layman but let me see if I can explain this. I recently heard of a theory that goes something like this: In relation to all the other physical forces in the universe, gravity is incredibly weak. To explain this, some think that our gravity is the result of a much more powerful force leaking into our dimension from higher ones. Or perhaps our gravitational force is leaking out into the lower dimensions. My question is about the validity of this theory. I don;t expect anyone to come out and prove it wrong or right or anything. But I was just looking for the opinion of someone with more experience than myself.

This is pure supposition, it has no physical basis what so ever.
 
actually I read something along those lines as well, it's been a while though so I don't remember where. I think it was in a magazine, either Discover or Scientific American, but it could have been one of about 100 physics books I've read in the past couple of years. I believe the article was about ways to "see" the extra dimensions
 
All forces are not equal and gravtiy does not need some sci-fi explanation to that. gravity is the result of two forces, one being the atraction of all matter to each other due to a part of string theory and another is the bending of space-time known as relativity. there is no need to make it more complicated with extra dimensions at all.
 
Hi,

Some string theorists say that gravity is so weak because gravitons can travel across the dimensions between branes.

Maybe you didnt know, but string theories all talk about 10 dimensions (or 11). So naming string theory as a cause of gravity and then saying there is no need for extra dimensions doesn't really make sense, unless you know a 4-dimensional string theory.
