Proposed Space Telescope Uses Huge Opaque Disk To Surpass Hubble
Required Snark writes NASA has funded a study of a geo-sychrounous orbit telescope that uses a half-mile diameter opaque disk to provide images with 1000 times the resolution of the Hubble. It uses diffraction at the edge of the disk to focus light, resulting in a very high quality image. It's named the Aragoscope, after the scientist Francois Arago, who first noticed how a disk effects light waves. "When deployed the Aragoscope will consist of an opaque disk a half mile in diameter parked in geostationary orbit behind which is an orbiting telescope keeping station some tens to hundreds of miles behind that collects the light at the focal point and rectifies it into a high-resolution image. 'The opaque disk of the Aragoscope works in a similar way to a basic lens,' says CU-Boulder doctoral student and team member Anthony Harness. 'The light diffracted around the edge of the circular disk travels the same path length to the center and comes into focus as an image.' He added that, since image resolution increases with telescope diameter, being able to launch such a large, yet lightweight disk would allow astronomers to achieve higher-resolution images than with smaller, traditional space telescopes."

Bad Science And Scary Science

The Truth About Aluminum Toxicity
One of the things that I have been hearing a lot of recently is that vaccines are dangerous because they contain aluminum.  Similarly, various chemtrail conspiracy theorists frequently cite aluminum as being one of the dangerous ingredients in their imaginary chemical discharges.  They’re not alone.  Others have said that children’s medicines contain dangerous amounts of […]
Chlorine Dioxide: A Horrific Treatment for Autism
I have written before about a product being sold as Miracle Mineral Supplement.  It claims to cure everything from cancer to malaria, but is actually one of the most dangerous quack products out there. Miracle Mineral Supplement is actually sodium chlorite, a toxic and reactive compound.  The instructions for Miracle Mineral Supplement tell users to “activate” […]
Some Revealing Videos from the “March Against Monsanto”
Around the world, people have come out to events dubbed the “March Against Monsanto.”   The events have happened in hundreds of cities (supposedly) and may involve thousands of people.  Overall, the total number who have come out for these events seems to be relatively small.  Most of them were lucky to draw a crowd of […]
SpaceX Will Attempt First Stage Recovery Launch – UPDATE
A brief post but something that really excites me. SpaceX was planning on launching a Falcon 9 rocket to the International Space Staton today.   This launch is not the first time the rocket has been launched nor the first mission to the ISS.  What makes it exciting (in addition to the fact that all rocket […]
No, it does not take a conspiracy to make people fat
 Videos like this one really get under my skin Click here if your browser does not support embedded videos   PEOPLE LIKE HIGH CALORIE FOODS. IT IS NOT A CONSPIRACY Foods that are high in calories, that contain a large portion of fat are simply something people like.   The same is true for starchy foods […]
An Open Letter About GMOs
An open letter to Europe and the world about GMOs in response to the ridiculous “Letter From America” about GMOs.   Of course, Europe and much of the world has been eating and benefiting from GMOs for some time. It’s a fallacy to equate GMOs with the United States.  However, it is true that the US […]
Terrifying Attack On Crop Duster
I should start off by saying that we do not know what caused this attack.  It could just be some drunkin idiots who were out shooting skeet and decided to shoot at an airplane. But these days there are a lot of people who believe that agriculture is ruled by evil corporations who are applying […]
The Babushka Lady: A Critical Missing Wittness to the Kennedy Assassination
On November 22, 1963, John F. Kennedy was shot and killed in broad daylight in Dealey Plaza in Dallas TX, in broad daylight and in front of numerous witnesses.  The overwhelming majority of those who were close to the shooting or who saw anything that was of importance were identified immediately and gave statements to […]
“Anti-Radiaton” Mobile Phone Device TV Ads
I might be a little out of he loop when it comes to what is on television.  I don’t really watch it all that often, and when I do, I usually am watching a DVR recording, so I don’t really sit through commercials. Yet the other day I caught this on TV.  Seeing it really […]
First Solar Roadway Built – And Worse Than You Would Have Thought
A few years ago, I touched on the subject of solar roadways.  The concept has gotten quite a bit of attention from the general public, mostly due to slick marketing.   It’s actually a terrible idea.  There’s really no more expensive way to pave a road, and, if you are going to have solar cells, you […]
