We held our first open “office hours” this past Friday, November 5th. We’ve taken the IRC transcript, organized and cleaned it up a bit, and posted it online for those who couldn’t make it. Self-interest. Supernovae make the chemical elements through real alchemy. To make it work better, he added a new mathematical constant into Newton’s famous law, calling the modification MOND, or Modified Newtonian Dynamics. Also, MOND can’t account for evidence of dark matter discovered by other techniques that don’t involve Newton’s second law, such as X-ray astronomy and gravitational lenses. Several astronomers have said that there’s no evidence for the Planet X theory, and that if the planet did exist, humans would be able to see it even without a telescope. Using the 340-megapixel camera on the Canada-France-Hawaii Telescope (CFHT) on Mauna Kea Mountain in Hawaii, scientists studied the gravitational lensing effects of 10 million galaxies in four different regions of the night sky over a period of five years. For example, in 2011, two teams used data from Chandra’s X-ray Observatory and other instruments such as the Hubble Space Telescope to map the distribution of dark matter in a galaxy cluster known as Abell 383, which is located about 2.3 billion light-years from Earth.

Besides giving the universe structure, dark matter may play a role in its fate. Axions may have been produced abundantly during the big bang. The big bang theory states that the early universe underwent an enormous expansion and is still expanding today. But while NASA has made considerable strides, many of these tools are still hard to find and use. First use of reaction controls for attitude control in space. A project of that scope also required massive public support, and NASA cannily touted the Mercury Seven as the mascots of the fledgling space program, turning them into national heroes and rallying the populace behind the agency’s lofty goals. Than, Ker. “Dark Matter Is an Illusion, New Antigravity Theory Says.” National Geographic. Milgrom, Mordehai. “Does Dark Matter Really Exist?” Scientific American. So, it is important to know how much dark matter exists in the universe. Sample, Ian. “Has dark matter finally been detected?” The Guardian. If dark matter particles exist, they should pass through solid earth and strike the nuclei of the germanium atoms, which will recoil and produce tiny amounts of heat and energy.

Super Cryogenic Dark Matter Search. Ultimately, the scientists decided the results of the dark matter experiment weren’t statistically significant, but it was another tantalizing clue in the search for the most mysterious substance in the universe. In some places, the dark matter coalesced into lumps. In other places, it stretched out to form long, stringy filaments upon which galaxies appear entangled, like insects caught in spider silk. When it turned out that space camp wasn’t just a product of Hollywood and actually existed, the fascination only got bigger. National Geographic. Archived from the original on 1 November 2020.

Non-competitive eligibility is a way to be appointed to certain federal positions without competing with the general public. Federal employees who blog while at work about their dating life, for instance, aren’t risking a Hatch Act violation unless they are dating a candidate. They are known as WIMPs (for weakly interacting massive particles), and if they exist, these particles have masses tens or hundreds of times greater than that of a proton but interact so weakly with ordinary matter that they’re difficult to detect.

One is known as a WIMP (weakly interacting massive particle), and if it exists, each particle would have a mass tens or hundreds of times greater than that of a proton but interacts so weakly with ordinary matter that it’s difficult to detect. The goal of LHC experiments isn’t to produce WIMPs directly, but to produce other particles that might decay into dark matter. Other experiments involve underground detectors hoping to register dark matter particles zipping by and through Earth (see sidebar). Who discovered dark matter?
