Discussion Overview

The discussion revolves around the visualization of 4D spacetime and the role of gravity within that framework. Participants explore various models and approaches to conceptualize these ideas, touching on theoretical and conceptual aspects.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions how to visualize 4D spacetime and gravity, suggesting it is a complex topic.
  • Another participant points out that this question has been previously discussed, implying that there may be existing resources or answers available.
  • A different viewpoint suggests that combining two spatial dimensions (z and y) with time as a third dimension can facilitate visualization, referencing common examples found in literature.
  • Another participant asserts that true visualization in 4D is impossible, but proposes that models can aid in understanding the concepts of spacetime and gravity.

Areas of Agreement / Disagreement

Participants express differing opinions on the feasibility of visualizing 4D spacetime. Some suggest methods for visualization, while others maintain that true visualization is not possible, indicating a lack of consensus.

Contextual Notes

Participants do not fully agree on the methods or models for visualizing 4D spacetime, and there are references to previous discussions that may contain additional insights or unresolved points.

Who May Find This Useful

This discussion may be of interest to those exploring theoretical physics, particularly in the context of general and special relativity, as well as individuals curious about the conceptual challenges of higher-dimensional spaces.

This is a FAQ; did you try searching for previous PF threads? This very question was discussed as recently as a few days ago.
 
If you take and combine two of the spatial dimensions say z and y then have time be your third dimension on a graph it is pretty easy. Its used in a lot of examples and what not in books.
