Well actually I'll stick to my shields and accept I am going soft sci-fi in that field because I don't want to rip of Pournelle since i like his work and it seems wrong to rip off people who's work you like

they did inspire me though since aside from the Harrington (gravity fields) it's the most unique shields I've heard of in sci-fi.
Although I know I won't be able to explain the "exact" physics of how the shields work since they defy our current knowledge of physics I'll explain just generally how they work

(non physics department)
Hey look at it this way though as far as my beams that can create a mini fusion explosion that is actually possible I think I'm not sure though.
And you think I am going "soft" sci-fi there is a series involving some group called "The Culture" where they shoot freakin black holes at each other as standard weapons (I mean real full fledged black holes not mini black holes). Or so I've been told, it all sounds a bit strange to me.
Same thing with this group called the 5th Imperium (don't know where it's from just heard about them on the spacebattles forums) where the average ship is the size of a planet and where they shoot unbeleivably outlandish weapons at one another.
