Does gravity defy the 2nd Law?

Perhaps an image is worth more than 100 words. This is my intuitive picture

I never stated that the cloud of gas could or could not radiate, that came only in some of the answers such as Anorlunda's.

You are the one who put it in the container, from which it can't radiate.

Personally, even now I do not see why such a gravitationally coalescing cloud of gas could not radiate to its immediate environment in the rest of the container.

What "rest of the container? Isn't it filled completely with a gas?

How does your scenario apply to the real universe? Why are we even talking about it? What game are we playing here?

Because of the impossibility to radiate

In general, if you are going to do that, it's best to do it somewhere where your previous messages are not stored.

And I'm done here.

The answer was given by @Demystifier in post #6: the wrong assumption is that entropy has been reduced.

Time to close the thread. Thanks to all that participated.
