Believe it or not, I did look prior to posting and didn't see something with a title indicative of the content of that article. Didn't realize it had been posted already.

Apologies.

I see now there's a post entitled "After Dark Matter & Dark Energy..." Didn't click before. Thought they were actually discussing dark matter and dark energy...

No breach of etiquette intended.

It might be a good "rule of thumb" to use the title of a news article as the title of the first post in a thread to avoid these problems in the future. If I'd seen the title "Dark flows across the universe" or some such I would have not re-posted it, as the content of the thread would have been clearer.

Will try to be more diligent in the future, in any event.
