Url changed from http://www.nytimes.com/video/science/100000002906469/collidi..., which points to this. In general HN prefers text to video.

I see, thank you. I'm sorry that I forgot to put "[video]" in the original title too, but of course that doesn't matter anymore.

The original link suits me better, as I've hit the article limit. The video link works fine.

FWIW, this result came out in 2012[0,1]. This NYT piece seems like it's just trying to use the non-event of the Swift/BAT detection[2] in M31 with with some other random M31 information to make a story. Unfortunately, there's not any new information in this NYT piece.
