If only atom sized, Titanium would create a dramatic increase in metallic elements that would in essence, create a solid wall of metal. If there is 1 light year of Titanium in area that a starship is traveling through, wouldn't the entire volume of Titanium be encountered at super fast FTL compared to encountering a lesser volume of Titanium at slower the FTL speeds? Then you have the magnetic and EM properties of Titanium to contend with that would be similar to flying close to a micro black hole possibly. The field would be generated as a result of the ship passing through the volume and encountering the Titanium atoms at a faster rate.
