So sorry to post what seems to be a well worn question. So the 4 forces of nature work by "particle exchange" ? Yes we understand the maths of "Fields" and we have the elegance of Maxwell and Newton/Einstein and these mathematical descriptions lead us to force exchange particles which can actually be predicted and detected. Whether these exchange particles are Particles or Waves (Photons, Virtual Photon, Long Wavelength Photons..................) my question is how do they create an attractive force ? Or is the physics of these realms now solely the domain of the mathematician ?
