My teachers in school use to say. "the dumbest question is the one not asked", but I might just break that rule with this one. Here goes.... I've been reading a lot of articles today on light travel, the Higgs field, and other fascinating stuff. Lastly, I was just reading an article about our radio signals and what has happened to them as they left mother earth. The article had an inset showing our galaxy. I then imaged, what if I was a being large enough to hold our galaxy in my hands. Just go with me here ... I know, I know ... there are all sorts of practical impossibilities here. Anyway, I could in a fraction of a large-being second move my finger from where our solar system is to the opposite side of the galaxy. This same distance would take use, of course, billions of light years to travel. Would various theories on light, you know E=mc2 stuff, scale with gargantuan comic size differences?
