Well, then explain it to me. What evidence shows that plasma would explode when it comes into contact with other plasma. If there is any real-life evidence that would be great, but since we're talking about two science fiction Universes, I'll have to settle for any sort of explanation I can get. WHY would plasma explode? What are the properties of plasma that would cause it to explode, fictional or real. It doesn't matter - anything you've got. I'm not sure how even you can understand the science of Covenant plasma. They may explain SW plasma, but I've never seen anything that explains how Covenant plasma works. Just because I haven't seen it does not mean it doesn't exist. But I've had quite a bit of exposure to Halo, as well as real world science (which Halo science seems to be based on). They could have just as easily said that the plasma is manipulated by *insert name of field here* fields, but they didn't, they chose magnetic fields because it works for real world plasma. While I'm not any sort of expert on plasma, I have a basic understanding of the principles involved. So what am I missing then? Enlighten me. Why would plasma explode when it comes into contact with SW plasma, but apparently not when it comes into contact with other Covenant plasma?

Oh, and I only mentioned the charged particle thing because in the real-world as well as most Sci-Fi Universes, it is accepted that plasma is essentially super-heated charged particles.
