As all comic book readers in 1961 knew, Cosmic Rays are the pixie dust of science. There was no telling what effects or uses could be attributed to the darn things. They granted fantastic powers like invisibility or controlled human combustion. They could transform a normal man into a super strong pile of orange rocks. They could enable certain speedsters to travel through time.
I’m not going to burst any bubbles of fantasy on this page, but if you really want to know what cosmic rays are all about, checkout this Japanese educational comic book published in 2008: What are Cosmic Rays?
