A couple of weeks ago on another forum (RPN), I brought up a couple flaws in the technology they were using in their role play world. But I get ahead of myself. RPN is a roleplay board that I visit fairly often, as I do have a penchant for RP, especially good RP. However my hatred of purely theoretical weaponry and technologies came to a head when the owner of the board proposed very high level electromagnetic weaponry (Read: railguns) for the application of SMALL ARMS. Now, as anyone who truly understands the working of a railgun and it's variants, I flipped a lid and went on for several posts about how such a thing is impossible, due to the fact that the size of the rails themselves directly dictate the maximum velocity of the slug. This is due to the fact that the magnetic charge on the rails and the magentic loop behind the slug itself which drives the slug to accelerate at one point become equal in charge. This means that the longer the barrel, the faster the slug (So long as certain energy requirements are met). But they actually have the gumption to say that UHV (High end railgun speeds, well over 10km a second) can be applied to PISTOLS when the maximum length of a railgun rail to achieve 10km a second would be around 10 meters, give or take about .5 of a meter. of course when I repeatedly bring up this fact they all jump on me using erroneous arguements based on emotions rather than facts. Ugh. Then during a discussion with the owner he says that they don't use electromagnetic propulsion for their "railguns" but rather a system of gravitic propulsion. I'm not 100% sure what gravitic forces are, but I think they are one of two things. 1. Manipulation of gravitons. It is my understanding that "gravitons" are theoretical at best. 2. Manipulation of gravitic waves or somesuch nonsense. Again, I'm not sure what these "gravitic" forces are. Perhaps I could recieve some info on them? I tried looking them up multiple times but to no avail, which leads me to believe it is the work of bad sci-fi. Any rebuttal suggestions would be nice, and uh... sorry about the rant-like nature of this post.
