Just a note: This is a laser pulse, not a single photon's worth of energy. (AFAIK)

As far as everything being dependent upon some sort of idea revolving around "frequency", I think it's more efficient to think of things as being manifested within discrete sorts of packets of information involved in complex and predictable actions. String Theory is a theory because there still isn't any proof of its validity. It may contain workable ideas, but that doesn't mean that existence is organized as it states/theorizes.

For myself, the idea that time exists and we somehow perceive it and we can somehow perceive entropy and things "changing" is more amazing. That what we perceive can actually be defined how we perceive it is also a wonderful mystery. And, that the Universe can somehow be explained in predicable, mathematical, terms is a confounding reality... There is no reason why it must be this way, but it appears to be "true."

It's also true that the most amazing thing about the Universe isn't that it exists in all its splendor and mystery, but that we can apparently understand it... There is no fundamental law, no reason that requires this to be true. Yet, apparently it is true.
