NASA is about to make an exciting announcement, apparently. On Monday 21st August there will be a press conference, and there will be actual information (they say) at several places mentioned in this link.
I have not the slightest idea of the details of the announcement [but see update below], except that the title of the page is “NASA Announces Dark Matter Discovery”! It concerns observations with NASA’s Chandra X-ray Observatory. The Chandra site says “Astronomers will announce how dark and normal matter have been forced apart in an extraordinarily energetic collision at 1 p.m. EDT Monday, Aug. 21.”, so I infer from this that they might not have completely pinned down the nature of the Dark Matter so much as found a completely new kind of smoking gun pointing to its existence.
On the other hand, the fact that they might have seen a real physical event suggests that there will be a lot more data about what Dark Matter’s nature might be. So I’m excited. You should be too. Be aware that we don’t know what about 83% of the matter in our universe is made of, except that we’re pretty sure that most of it is not the ordinary stuff contained in our list of known matter types, but something more “exotic”.
So maybe this announcement is about a significant chunk of the Dark Matter, or maybe a less significant and less exotic chunk. I don’t know. But it’s not every day you get to find out what a large amount of the matter in your universe might be made of.
So watch that space (or those spaces), for the results of watching, er …. space, if you get my meaning.
This could be exciting.
[Update 2: There seems to have been a leak! See the first comment! I’ve put the key information here. We shall see on Monday….]
(Spotted at Elron’s View From The Edge.)
(Update 1: Sean of CV probably has more of the inside scoop -see here– so maybe more over there on Monday.)
