ASTRON and IBM to Collaborate on a New Customized Chip Design to Help Build the World's Largest Radio Astronomy Telescope.
Amsterdam, The Netherlands and Armonk, NY - 06 Dec 2006:
ASTRON, one of the world's leading astronomy research organizations, today announced a new collaborative agreement with IBM (NYSE: IBM) focusing on the design, engineering and manufacturing of customized, high performance analogue and mixed signal processing chips. The high performance, low power usage customized chips will be used in thousands of antennas as part of ASTRON's project to build a new prototype radio telescope called SKADS/EMBRACE, which will be the precursor for the world’s largest radio astronomy telescope, the Square Kilometer Array (SKA) radio telescope. Financial terms are not being disclosed.
It seems to be a widely spread misconception that the bending of light provides "direct" evidence of dark matter. An observation of lightbending only indicates that something has to exist which causes the bending (which does not contain so much information :tongue: ). If one then ASSUMES that the lightbending is due to gravitation, one could infer the presence of unseen (dark) matter. Direct evidence of dark matter should be that one can interact with it, study it in particle accelerators, etc.
