Actually, you can. Just like you can get a royal flush in a game of poker. Both the reverse entropy and the royal flush would be an extremely rare occurrence, but they can happen on occasion.

As I said before you can not reverse entropy, therefor there is at least one thing that is impossible. Use your noodle I'm sure you can think of some others.

Does the second law of thermodynamics really hold good without exception?
I've seen other discussions about entropy exceptions too, but they seem fairly trivial to me, like just statistical anomalies that can happen statistically in any system.
However I've never seen any exceptions to the velocity of light proven, and this neutrino case falls short of proof. So I agree with your basic premise that based on our observations, we have at least some evidence to contradict the assertion that anything is possible. Our measurements and observations at least suggest that's probably not the case.
I said there were other references so of course I'm glad to provide something for you. You can calculate the odds of getting a royal flush without experimentally ever playing a single hand of poker, and theoretically your statistical predictions should be accurate but of course it's hard to verify an exact number in experiment when probabilities are so low. Statistics can work similarly in entropy but it has supposedly been experimentally verified:

We experimentally demonstrate the fluctuation theorem, which predicts appreciable and measurable violations of the second law of thermodynamics for small systems over short time scales, by following the trajectory of a colloidal particle captured in an optical trap that is translated relative to surrounding water molecules. From each particle trajectory, we calculate the entropy production/consumption over the duration of the trajectory and determine the fraction of second law–defying trajectories. Our results show entropy consumption can occur over colloidal length and time scales.
The fluctuation theorem (FT), which originated from statistical mechanics, deals with the relative probability that the entropy of a system which is currently away from thermodynamic equilibrium (i.e., maximum entropy) will increase or decrease over a given amount of time. While the second law of thermodynamics predicts that the entropy of an isolated system should tend to increase until it reaches equilibrium, it became apparent after the discovery of statistical mechanics that the second law is only a statistical one, suggesting that there should always be some nonzero probability that the entropy of an isolated system might spontaneously decrease; the fluctuation theorem precisely quantifies this probability.

No the community is not aware of that because it didn't happen.

Scientists make radio waves travel faster than light
You see it as an attack. I see it as being blunt and calling it as he sees it. Physics was one of my majors as a university undergraduate, and buddhasystem's posts on ATS demonstrate he has a higher knowledge of physics than I do, so when he says he has a PhD, I see no reason to doubt it. However if you made that claim I'd have ample reason to doubt it. You tend to make claims that you aren't able to back up with evidence. The ability to back up claims with evidence is one of the traits of a good scientist.
