There are somethings in this world that will never be explained. Who let the dogs out? Was there a second shooter on the grass covered "small hill or mound"? (someone once asked me what a knoll was, so rather than get that question again, I defined it. You're welcome.) If a tree falls in the forest and lands on somebody, does the tree care?
Well, one mystery can finally be put to rest. Photons cannot travel faster than light. This is like saying that sound waves cannot travel faster than the speed of sound. Considering a photon is basically a unit of light, it means that light cannot travel faster than itself.
I know there is more to it than that, but this has got me thinking... if someone can get a grant for proving light travels at the speed of light, could I get a grant to prove arachnids have eight legs? Or perhaps, could I study the spelling of the word aardvark? I mean, why the double 'a' to start the word? It's not pronounced a a rdvark.
I also have a theory on who let the dogs out.
