POPSTelescope spots monster galactic cluster They theorize that the fact that it's 7.7 billion light years away (as far as they know) meant that it was before the acceleration due to dark energy made it impossible for galactic clusters that large to hold together. It reminded me of a poem by Hughes Mearns. 'Antigonish' As I was going up the stair, I saw a star that wasn’t there. It wasn’t there again today, I wish, that star would stay away. (I thought I'd adjust it to cover Light years, and dark matter.)

POPSWhat if Electricity Was FREE??? The life story and work of Nikola Tesla. He invented AC electricity, Neon Lights, Radio transmission, The Electric motor, Wireless electricity transfer, Remote control, Hydraulics, Lasers, Space weapons, Robotics, and many, many more things. As Tesla claimed to have invented a way to harness free energy from the voltage difference in the ionosphere that causes lightning, he was seen as a threat to the world energy economy and most of his inventions were classified for national security by the US government. A lot of his discoveries in physics have not been released to the public, despite being invented nearly 100 years ago. In 2006 the first company publicly announced it could successfully power items by remote power without wires, (news.bbc.co.uk/1/hi/technology/6129460. stm) something Tesla had invented nearly a century ago.

POPSSurfing faster than the speed of light I wonder how easy it will be to navigate with these drives. Will the passage of a vehicle through space-time in a bubble leave an imprint? they could start some rifts around bottlenecks like docking stations.

POPSDino diversity earlier than first thought Maybe there is the idea that species including the dinosaurs were trying to deal with conditions brought about by the meteor, so many adaptations arose, but nature loves nothing more than competition, even when times are good.

POPSEchoes of a Supernova: Spitzer Space Telescope We can't physically travel back in time (yet?) but the complete history of the universe lays before our eyes. As our technology, and understanding improves, what we can read of that history also improves, continually answering questions that we had not dreamed of just a short time ago.

POPSAtom laser to keep spacecraft on track. Models predict that the atom laser will be 11 orders of magnitude more sensitive than light laser gyroscopes, offering measurements that could be 100 billion times more precise.

POPSOuter-space sex For all these reasons, Logan said spontaneous sex in space could be "a little underwhelming." "It's a pretty messy environment, when you think about it," he said. "And for every action there is an equal and opposite reaction. However ... I can well imagine how compelling, inspiring, and quite frankly stimulating choreographed sex in zero-G might be in the hands of a skilled and talented cinematographer with appropriate lighting and music." When the crowd tittered, Logan added, "I'm not kidding: Sex in zero-G is going to have to be more or less choreographed. Otherwise it's just going to be a wild flail."

POPSCreating insignificant events -Futuristic art Vincent Callebaut 'work was lately exhibited in Paris ; ;" To believe in the world means to create events, even insignificant ones, that gets out of control, or create new space-times, even in reduced surfaces or volumes"

POPSMultidimensional space through art Generally for the sake of the illusion of 3 Dimensions and perspective. There are plenty of artists beside Escher that represent multidimensional space, but he does a particularly good job of it. The last stereogram at the bottom is the thinker. I ran out of characters. (you can always go to the site.) Stereograms can be annoying sometimes when you can't see what it is, and everyone else can. It can be like that, then suddenly one day a picture can jump out. It can help if you know what you're looking for. One problem with these may be looking too hard, when the eyes are probably better off relaxing.

POPSHubble Image Collection v3.0 There is a 500mb download that contains 130 of the best images from the NASA/ESA Hubble Space Telescope., each in three resolutions. There is also a list of 'goodies' on the left of the page with a range of Hubble downloads,

POPSNASA says German whiz kid got it wrong Sounds bizarre, NASA figures showing the chance of an asteroid strike being shown up by a boy's school project, but that was the claim made by a German newspaper. NASA seems to be taking it seriously. While they calculate, they still haven't worked how to argue with an asteroid that has made it's mind up. NASA also claim the boys figures relate to a single asteroid hit on a satellite in 2029. Looks like they both had the same answer with their decimal points in different places. Did one of them forget how many significant figures they were using ? From the figures it looks like they both

POPSPlot of the Innermost Solar System, March 29, 2008 The plot below shows the current location of the major planets (Mercury through Mars) and the minor planets that are in the innermost region of the solar system. Just in case you thought it's lonely out there in the space ;-)

POPSHeritage computers facing scrap heap
April 1 is the deadline. Many of the computers may be useful for research or historical purposes, perhaps to help put into some context how far Moore's Law has got us over the last 50 to 100 years To think computers started with vacuum tubes, as transistors. These aren't that old but they do take up a lot of space. Often it is discovered something is needed just after it is thrown out. Perhaps throwing it out was a reminder that something still existed, but it's easy to forget how we got here if there's no hard copy. Human memories can be very subjective. Computer memories are much more logical. The way humanity works, if we bury them now in a few years well regret we didn't wait until we had at least generated a 3D Graphics program that contains all of the information, from hardware layout and format to programs, in the one folder. It will be too late then, we'll have to be content with b/w photos, and perhaps personal descriptions. Maybe Wikki will tell us what they were like.

POPSHunt is on for tiny diamonds in space Carbon does have remarkable properties. One of the four basic organic elements, present in any number of compounds including pure carbon compounds like graphite and Diamonds. Mainly because the atom is built like it has four plugs, and four sockets. They think according to the meteorites that there is a vast amount of carbon in interstellar dust and think it may give them clues to the way carbon molecules form, including those that are the precursors of life. Then of course there's Lucy in the Sky with Diamonds? The 60s does seem to be a long time ago, and as they say, if you remember it you weren't there.

POPSMark Shuttleworth - Space Man Of course Ubuntu/Linux is my latest preoccupation (apart from clipmarks) and when I read he was behind it, and was described as an 'Entrepreneur' so I had to find out more. There are more than a few types of 'Entrepreneur' when I saw that a few years ago he was most famous for going with the Russians to the International Space Station, (It's easy to forget much of what happened more than 7 years ago) I thought it would even have made the Russians laugh, and that isn't easy. He's involved in community projects in South Africa, concerning Education and free software, to allow greater access to learning, and computer technology. He's also been to Antarctica aboard a Russian Icebreaker.

POPSWarships poised to shoot down satellite They say they must deal with the 'toxic propellant hydrazine I fail to see how a missile can deal with it any better that reentry Perhaps the missiles are surplus and they need to justify military spending. How much hydrazine is there? The satellite was defunct. The whole equation just doesn't add up. The cure seems to be far worse than the problem.
