So why does hyper­mod­ern tech like per­son­al force fields and air­borne autos still fly through the pages of sci-fi nov­els and across movie screens? Where there aren’t sci­en­tif­ic impos­si­bil­i­ties, there are sci­en­tif­ic (and oth­er) obsta­cles. Some tech­nol­o­gy is viewed as pos­si­ble but so com­plex that we are still in the pro­to­type stages. Some has been the­o­rized but not even researched yet.
