The correct statement is: CLOSED Physical systems cannot produce more information at their output than was present at their input.

Please give an example of an OPEN physical system?

Also, it has been remarked that there is no known "natural" cause of information. What do you make of a statement like that? How would you contradict it if you think it incorrect?

Must go out to tend to "elder care" this afternoon. But I'll be back later.

“Please give an example of an OPEN physical system.”

The Earth, for one. Energy, in the form of sunlight and starlight and radiation, comes in continuously; additional material arrives in the form of meteorites and cosmic dust by the tens of thousands of tons per year.

The jello you are seeking to nail to the wall will switch from a local system to the system that is the known universe as it suits the rejection agenda. The truth of it is that neither side has all the data possible so neither side has sufficient data to prove an ultimate claim thus both sides are based on faith not proof.

Your body is an example of an open physical system.

So is the Earth.

In information systems to which entropic proofs apply, computer networks (the network proper) is a closed system, whereas computers themselves generally are not (because they are connected to both sinks and sources of information.)

When you make the claim that entropy must increase, you must be talking about either a) the entire universe or b) a system which cannot effectively lose or gain energy from outside. There is no requirement in physics that the entropy of open systems must always increase. It is in fact quite typically the case that the entropy on one side of an open system decreases.

Also, it has been remarked that there is no known "natural" cause of information. What do you make of a statement like that?

It is objectively false.

How would you contradict it if you think it incorrect?

I would point to my own brain, which like the trees and stars, is a part of nature.

Because space/time is finite, when the universe is the subject - it is closed.
