The fact that it makes a big cloud around a galaxy or cluster rather than collapsing puts a lot of constraints on what it can do.

For more info, you'll have to go to someone who knows more about it than what I've read on science-news websites.

Dark energy is a real puzzle. As I understand it, it's too weak by a factor of 10^30 or 10^60 in comparison from what we should expect the known vacuum energy would cause. You see this mentioned very occasionally, but most treatments of DE that a layman runs across just ignore it in favor of wringing their hands over some issue that is trivial in comparison.

Some boffin cam up with that idea, but they rule it out because DM apparently doesn't interact with itself (very much) other than by gravity, so it can't clump up tight like a star or a planet or a living thing. (Something to do with shedding energy, IIRC.)

But it's a cool idea. If I were a novelist I'd run with it.

Some calls are repeats, either different people calling about the same event or the same person calling when he or she doesn't get through. 911 also gets automated calls from alarms, some of which are false alarms. That's why, of the 1700 calls that could not be heard, they estimate that about 400 represent human callers who did not get through.

Submission + - New York City 911 system missed 1700 calls due to software update

belmolis writes: Part of the New York City 911 emergency system was off-line from 3am to 10am on August 18th due to a software update according to Medical Daily. Of 5,659 calls to the Bronx call center, 1,700 calls connected but could not be heard by emergency operators. Some were rerouted to other call centers, but an estimated 400 human callers never got through. The potentially serious consequences of delayed response to emergencies are not yet known. The City did not notify the public and only released information when journalists inquired. How buggy software came to be installed on a running system is not yet known.
