LUX Detector Nearing Activation for Dark Matter Observation in SD Mine

A South Dakota mine is the venue where the Large Underground Xenon Detector, a device designed by scientists, would be activated to detect the presence of dark matter, a substance that makes up 25% of the existing universe, which has long eluded scientists for the past few decades. It was lowered this into a 70,000 gallon water tank nearly a mile beneath the earth’s surface insulated enough to help it insulate dark matter from cosmic radiation that masks the substance on the earth’s surface.

The discovery of dark matter will shake the entire scientific community as it can answer the origins of the universe and the behavior of reality. Harry Nelson, a physics professor in the University of California and also a principal investigator of the project, stated that the experiment might be brutal or expensive, but it would be as astounding as the discovery of the Higgs boson earlier this year.

Regular matter, such as in the physical world, makes up 4% of the physical universe. Dark matter makes up at least 25% of the universe and the other parts, such as dark energy, still remains a mystery to most scientists.

Right after the Homestake Gold Mine in the Black Hill’s Lead in South Dakota shut down, scientists applied for permissions to use the site for experiments, which had the LUX move into the Sanford Underground research facility which is 4850 feet below the earth’s surface.

The detector, roughly the size of a telephone booth, is submerged in water running through reverse osmosis to deionize and clean it to make it more sensitive to detecting dark energy. Xenon in both liquid and gas form will fill the detector and continuously circulate through a purifier, similar to an osmosis machine.

EE Launches First 4G Mobile Internet Service in UK

EE, known formerly as Everything, Everywhere, launched their 4G mobile service in London, Manchester, Bristol, Birmingham, Cardiff, Edinburgh, Leeds, Liverpool, Sheffield, Southampton and Glasgow Tuesday morning. Network EE is the first company to provide 4G mobile Internet services that offers from 8-12 mbps, a faster speed compared to the current 3G services available.

However, issues about its data usage allowance and daily limit sparked criticism from industry experts. While the extra speed can allow for high-quality audio streaming and faster Internet access while on the move, shows and other videos that run for 30 minutes can reach up to 225 mb. This can create add on costs aside from the entry level 500 mb of data each user has paid for £36 a month. Add on costs can begin with £3 for 50 mb and £20 for 4GB

EE states that it would be providing standard customers with 8GB data allowance with a deal costing £56 a month. They mention that the prices were based on consumer research and the prices were the best “spot” they can find in the price range.

Analysts are quite skeptical about how EE would make customers believe that 4G services is good value for money given the cost. However, these challenges were to be expected being the first company to take initiative in launching the 4G service.

Other telecom companies are scheduled to launch their own 4G services next month. Only EE was granted the permission to launch their next generation service using their existing bandwith.
