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.","brand":"World Scientific Publishing Co Pte Ltd","offers":[{"title":"Default Title","offer_id":51047216185687,"sku":"9789810225735","price":19.95,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/1739\/5799\/files\/9789810225735.jpg?v=1750970709","url":"https:\/\/bookcurl.com\/products\/lectures-on-cosmology-and-action-at-a-distance-electrodynamics-9789810225735","provider":"Book Curl","version":"1.0","type":"link"}
