I fail to see how 'getting out of studying' something is any part of this. Point charges are an idealized point particle that appears in classical electromagnetism because it deals with electrical fields and the infinities that appear are rather a matemathical artefact not a description of...

Well luckily they don't and classical electrodynamics has been superseeded by QED. But i do take it that the same principle applies in the description of singularities if i get that right ? I.e. that's the principle that was used to describe them.

First, seeing all the disagreement, I'm glad that my question isn't totally dumb :D I'll try to respond to all points raised: The dirac delta function example is in a way just a fancy way of saying: 2∞ > 1∞ (which mathematically may make sense but in this case isn't exactly useful as we are...

A singularity would be: a location in spacetime where the gravitational field of a celestial body is predicted to become infinite by general relativity in a way that does not depend on the coordinate system. (wiki) If the threshold to get a singularity is reached then space-time curvature...

Hi, Thanks for the reply! To make myself a bit more clear... I mean a list of all possible couplings whereby another elementary particle is created out of an interaction... ex: http://www.quantumdiaries.org/wp-content/uploads/2012/01/qed_bbbar_sChannel.png (this would be an example of how to...

Hi, I'm not sure if this idea is something old that's been discussed to death or something I'm not formulating right, but i can't find anything online like what I would expect to. What I mean, is a list or rather a table of all possible elementary particle transformations and couplings from...
