But now, by modifying metals like Silver and Aluminum at the subwavelength scale, researchers are developing "Meta-Materials" that causes light to interact with these metals in new and interesting ways. One of their more promising goals is to create a "perfect lens" which would allow an every day person to view things as small as a virus with the naked eye. Will this eventually lead to whale sized fish tanks as clear as glass with the strength of aluminum? Only time will tell.
