The following is not a question: Can something come from nothing?

[John V]

Why did the cascade so obviously violate your sense of time, while the other parts of the creek did not? The reason is entropy: the cascade is, from the physics point of view, a very irreversible process which produces lots of entropy. The creek running its course quietly produces entropy as well because of the friction the water experiences, but much less so than the cascade.

The surprising thing is this: nothing in the backwards-running movie violates the laws of physics.

Er, water falling (so to speak) up seems to violate the laws of physics to me.

Note what has happened: we use the words which have meanings in our everyday lives as well as in science, and try to apply them in a scenario so different that none of them retain any meaning. Two things spoil the question: if there is no universe full of particles doing their statistical dance, there is no notion of an arrow of time, even if we assume that time as a continuous parameter exists. However, if we let even go of this, if we feel compelled to talk about the creation of time itself, all meaning is lost, and the questions we utter merely resemble questions, but in reality only mimic them.

In appealing to a time or state or what have you in which the laws of physics as we know them don't apply, you're appealing to the supernatural, like the theist.
