Thus it has electric charges interacting with one another directly and not through the medium of a field. In general such an interaction travels forward and backward in time symmetrically, thus apparently violating the principle of causality. It turns out, however, that in such a description the cosmological boundary conditions become very important. The theory therefore works only in a cosmology with the right boundary conditions; but when it does work it is free from the divergences that plague a quantum field theory.\u003c\/p\u003e","brand":"World Scientific Publishing Company","offers":[{"title":"Hardcover","offer_id":46893109215383,"sku":"9789810225582","price":5978.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9789810225582.webp?v=1770313967","url":"https:\/\/atlanticbooks.com\/products\/lectures-on-cosmology-and-action-at-a-distance-electrodynamics-9789810225582","provider":"Atlantic Books","version":"1.0","type":"link"}
