Discussion Overview

The discussion revolves around the concept of space-time as described by Einstein, particularly the idea of waves or ripples in this "fabric." Participants explore the implications of this notion for light and electromagnetic fields, as well as the relationship between these ideas and higher-dimensional theories.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • Some participants inquire whether waves can exist in the fabric of space-time as described by Einstein.
  • One participant references gravitational waves as a related concept, linking to external resources for further reading.
  • Another participant suggests that light might be explained as moving magnetic fields, potentially viewed as waves in the fabric of space-time.
  • There is a proposal that electromagnetic fields are not ripples in space-time, but some suggest that exploring higher dimensions (5 or more) could yield equations that describe light's movement.
  • One participant expresses curiosity about the nature of the electrostatic force of electrons, questioning whether it arises from charge repulsion and momentum or other factors.

Areas of Agreement / Disagreement

Participants express various viewpoints on the nature of electromagnetic fields and their relationship to space-time, with no clear consensus reached on these ideas. The discussion remains open-ended with multiple competing perspectives.

Contextual Notes

Some claims depend on the interpretation of Einstein's equations and the implications of higher dimensions, which are not fully resolved in the discussion. The nature of electromagnetic radiation and its transmission without a medium is also a point of contention.

If, according to Einstein, that space-time is a "fabric", could there be waves in this "fabric"?
 
Physics news on Phys.org
thanks man.
 
I also wonder if light can't be explained as moving magnetic fields, which themselves may be slight waves in the "fabric."
 
Moving electric and magnetic fields both. It's not thought that the electromagnetic fields are ripples in the fabric of space but actually there are suggestions that this could be the case.

The most tantalizing such suggestion is this: if you work through Einstein's equations for ripples in the fabric of space but you use 5 dimensions instead of 4, the equations that descrlighthearted movement of light also appear.

This kind of thinking has been carried forward over the century and joined with another great theory in physics called quantum mechanics to produce the best attempts we have to describe the universe. The number of dimensions has gone up from 4 to 10 or 11, so your intuition is good.
 
Blast autocompletion and the iPhone app on this site.

Descrlighthearted should read "describe the movement of" but I can't edit the post because the window won't scroll down.
 
Magnetic fields do not require a medium, so they are the best candidate, imo, for explaining the ability of electromagnetic radiation to transmit energy without a medium. What I want to figure out is how the electrostatic force of electrons occurs. Is it a combination of the repulsion of negative-negative electron charges and their momentum or something else completely?
