I Gravitation In Higher Dimensions

AI Thread Summary
Gravitation in higher dimensions is believed to follow a 1/d^(n-1) law, differing from the 3D case where a uniformly dense sphere's gravitational attraction is equivalent to a point mass at its center. For dimensions greater than three, this equivalence does not hold, prompting a search for the results in those scenarios. The discussion seeks to use the known 3D integration case as a model to understand higher-dimensional gravitation. A suggestion to search for the "gravitational shell theorem" was provided as a helpful resource. Understanding these concepts is crucial for exploring gravitational dynamics in n-dimensional spaces.

It is assumed that gravitation in n dimensions would follow an approximate 1/d^(n-1) law. In our 3D world the attraction of a uniformly dense sphere is the same as if all the mass were concentrated at its center. I have read for n>3 this is not so. I want to find out what the result would be. I think I can do it if I have the common n=3 integration case as a model. I tried an Internet search but could not guess the correct search term. Any help?

Thread 'Mechanism of Energy Conservation in Zero-Amplitude Sum of EM Waveforms'

Assume that this is a case where by sheer coincidence, two sources of coherent single-frequency EM wave pulses with equal duration are both fired in opposing directions, with both carrying the same frequency and amplitude and orientation. These two waves meet head-on while moving in opposing directions, and their phases are precisely offset by 180 degrees so that each trough of one wave meets with the crest of the other. This should be true for both the electric and magnetic components of...
