Dark Matter's Rival: Ether Theory Challenges "Invisible Mass"

A concept abandoned in the 19th century is being revived by a physicist as an alternative to dark matter, despite recent announcements of proof of the theoretical substance.

Liberal bias versus right-wing conspiracy is a wonderful distraction. There is evidence enough on both sides. How can opposite claims be true? Confront a physicist with evidence supporting contradictory hypotheses and she will go looking for a more basic cause. Let's try that.

It's "all systems go" for one of the most ambitious physics experiments ever attempted. After more than 40 years of methodical planning and four months of intense troubleshooting, NASA's Gravity Probe B spacecraft has begun its search for a bizarre prediction of Einstein's relativity.

It's a question of keeping up standards. That famous slab in Paris has lost 50 micrograms, so Australian scientists are creating a perfect sphere out of Silicon 28. They even know how many atoms it'll contain.

A cosmic explosion that seems to have come out of nowhere&#x2014;thousands of light-years from the nearest collection of stars&#x2014;has left astronomers baffled.

News about the rumored discovery of the Higgs boson "God particle" is as elusive as the Higgs itself. Weeks of rumors say more about the sociology of science than about science itself.

European Space Agency -- 'Consensus on conditions in the cloud of interstellar gas surrounding the Sun from several in-situ observation methods'     Through coordinated observations with instruments on several ESA and NASA spacecraft and a collaborative analysis effort hosted by the International Space Science Institute (ISSI) an international team of scientists has compiled for the first time a consistent set of the physical parameters of helium in the very local interstellar gas cloud the surrounds the solar system.     Careful analysis of data from three complementary observation methods produced a reliable set of physical parameters for the local cloud which can be used to model the interaction between the Sun and the surrounding interstellar gas and establish dimensions of the solar system...

In a follow-up to a previous blog post, Alexey Zakhlestin shares a few more thoughts on the project and the proper object hierarchy's going for.   actually, I changed it completely 3 times already in my thoughts. I finally "see the light"(tm) and will implement it on a weekend. I think about converting SCGI-part to a simple "driver" and move all http-related stuff to a separate driver-agnostic set of classes. This way, I would be able to implement FastCGI as anther driver without altering applications. If you have any better ideas - let me know.   He also includes a link to another sample application that uses the functionality to create a pie chart (including some benchmarks) with the help of the eZ components framework.

Black holes are dark secrets, shrouded in churning spacetime and scrunched into points smaller than an atom. In recent years, astronomers have successfully penetrated some of their mysteries, but fundamental questions about what they are and how they work are still unanswered.

Tycho:   The foe revealed, Armadeaddon is now almost complete.  Monday will see the promised epilogue, so at this point you have very nearly survived the ordeal.  We have endeavored these past weeks to reward the true "enthusiast," that man or woman who, brow heavy, has faced such cruel abuse at our hand for the last seven years.  It is apparently our policy to honor such dedication one every decade.    Since it was announced a couple days ago, the revelation that MS would be actively courting the hardcore boardgame player is something I've thought about almost constantly.  It may be that you weren't aware there was such a thing as a hardcore player of boardgames if your last experience with the context was playing Sorry! with your sister when you were eight.  Things have progressed.   There's a million experiences in this space I could use to lure you in, but one company in particular - Days of Wonder has already decided to make electronic variants of their tabletop crack, so they occupy a twilight space between the worlds.  I hope they see an opportunity to take their (already completed!) games over to the 360, or that Microsoft offers them a locked case containing an unspecified amount of untraceable U.S. Currency, because I'd love to see this prescient move by MS turn into a new era.   Days of Wonder makes a game called Shadows Over Camelot that could quickly become a dangerous obsession, obscuring biological realities with a single-minded focus on grails.  Well, grail I guess.  There's just the one.    But it's a completely cooperative boardgame, so every player is working toward the same goals - fighting back invasions, questing, all of it.  Except there might be a traitor in the group, determined by a hidden draw, who tries to derail the effort.  He's not always there, but the potentiality of that nefarious force can create unbelievable social tension.    The gaming table's fixed coordinate in space is its asset and its obstacle - managing space and time is actually the primary challenge of any gaming group, as opposed to banishing necromancers, though that also ranks up there.  Boardgames are so rich in design that, when one of these gets dropped in front of them on Live, I think many gamers will be shocked at their sophistication.    My thumbs hurt.  (CW)TB out.

To first-time viewers, the 50-foot-high Forevertron might look like nothing more than 320 tons of towering scrap metal. But its creator says it's also an antigravity machine designed to propel him to the heavens. Michelle Delio reports from Prairie du Sac, Wisconsin.
