That's one oddity. The other is that they all like to make up fancy stuff like antimatter bombs and all that, and completely disregard how powerful this really would be and what kind of devastation it could wreak.
Worst example might be some of the Star Wars tech stuff. I am not really sure that the whole concept of "Hypermatter generators" and what not are supposed to be canon or just some fanwank, but it seems ultimately bullsh*t beyond belief. They make up giant numbers, and then have humans survive a blaster hit to the shoulder or giant walking tanks destroyable with two tree trunk.
It is a (tv)trope that science fiction authors have no sense of scale, but some cases are worse than others.
