Discussion Overview

The discussion centers around the dimensions proposed in M-Theory, specifically seeking to identify and describe the 7 additional dimensions beyond the familiar 4 dimensions of space and time. The conversation explores theoretical aspects of M-Theory and its implications in the context of string theory.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant notes that M-Theory involves 11 dimensions, including the 4 dimensions of our natural world (length, breadth, height, and time), and requests names and descriptions for the other 7 dimensions.
  • Another participant lists the 4 known dimensions as x, y, z, and t, and proposes the additional dimensions as w_1, w_2, w_3, w_4, w_5, w_6, and w_7.
  • A different participant argues that the extra dimensions do not have names or measurements and references the concept of a 10-dimensional spacetime with a 6-dimensional Calabi-Yau space, suggesting that understanding this requires significant mathematical knowledge.
  • One participant proposes an alternative view that time may consist of 3 dimensions (past, present, future), which would imply only 5 additional dimensions need to be named.
  • Another participant challenges the previous claim about time being 3 dimensions, asserting that the extra dimensions in string theories are spatial and that the claim contradicts the definition of "dimension."
  • A participant suggests that the frequency of this question indicates a need for a well-crafted explanation to be made a FAQ sticky.

Areas of Agreement / Disagreement

Participants express differing views on the nature and number of dimensions in M-Theory, with no consensus reached on the names or characteristics of the additional dimensions. The discussion remains unresolved regarding the interpretation of time as multiple dimensions.

Contextual Notes

Some claims rely on specific interpretations of dimensions and may depend on advanced mathematical concepts that are not universally understood. The discussion reflects varying levels of familiarity with the topic among participants.

Through a period of 60 years we developed quantum physics that enables us to imagine far beyond the capacity of an ordinary human mind. Quantum physics developed several String theories that were united in creation of M-Theory. M-Theory invovles 11 dimensions including the 4 dimensions that control our natural world (length, breadth, height, and time). I was wondering if someone can provide me with the names, measurement, and describtion of the other 7. Thank you for your answer and time.

i am a new to the world of physics and i would really much like to understand stuff that i don't quite seem to understand but can reason with. so please be cautious if i mentioned anything out of hand and sounding "dumb". thank you =X
 
Four dimensions: x,y,z,t
7 other dimensions : w_1,w_2,w_3,w_4,w_5,w_6,w_7
 
They don't have names, and they haven't been measured. I don't know string theory, but the elegant universe describes the 10-dimensional spacetime as the familiar 4-dimensional spacetime with a 6-dimensional Calabi-Yau space attached to each point. It isn't really possible for someone who hasn't studied a lot of math to understand what that is. The 11th dimension of M-theory is apparently something even stranger.
 
It has been argued that time may infact be 3 dimensions and not one. That past, present and future are like height width and depth leaving 5 dimensions to be named instead of 7.

That makes no sense at all. The extra dimensions in the string theories are spatial dimensions, and your claim isn't even consistent with the definition of the word "dimension".
 
This question is asked in here often enough I think maybe the Authorities should consider finding a really good explanation and making it a FAQ sticky or something.
