college station scientists from around the world will join texas a&m universitys top experts in high-energy physics and astrophysics for a three-day workshop beginning friday (march 8) that will delve into dark matter the unknown substance that makes up nearly a quarter of the universe roughly three dozen dark-matter researchers from the us and around the world including england germany and japan will fly into college station for the march 8-10 dark matter workshop hosted and funded by the george p and cynthia woods mitchell institute for fundamental physics and astronomy unlocking the mystery of dark matter means unlocking the mystery of the universe an 80-year-old odyssey currently surrounded by buzz as nobel laureate samuel ting has said he will make an important announcement soon about his research into dark matter its an epic space race that texas a&m is uniquely positioned to be a key player in says high-energy theorist bhaskar dutta thanks to department of physics and astronomy researchers who are involved in every known method and international experiment (see list below) currently encompassing the high-stakes global hunt we only understand 4 percent of the universe right now said dutta interim director of mitchell institute once we know this 23 percent that is dark matter were hoping it may give us a lead into understanding the remaining 73 percent which is dark energy once we understand it all then well know the past present and future of the universe such a discovery could be impactful beyond a basic understanding of the universe dutta notes when quantum mechanics was discovered no one knew that one day youd use the microwave at home to heat up your food dutta said no one can predict during those moments of discovery where this will eventually lead once we start knowing this stuff there will be spinoffs dark matter named such because it is an unknown that does not interact with light cant be seen directly by telescopes and doesnt emit or absorb light at any significant level its not like any normal matter such as stars planets or any living or nonliving material on earth its not even a black hole the search for understanding dark matter dutta said focuses on two questions: what is it and how was it created scientists around the world are trying to answer these questions using three methods: direct detection indirect detection and a collider method in direct detection researchers wait for dark matter particles to hit a detector through indirect detection experiments search for the products of the annihilation of dark matter particles in the collider method dark matter particles are produced when protons are collided and observed as missing energy most other places are strong in a particular method dutta said texas a&m is strong in all of them theres a beautiful collaboration going on here among the theorists and the experimentalists dutta said he hopes the gathering becomes an annual event to study dark matter and trade theories within a small focused group to learn more about the mitchell institute go to http://mitchellphysicstamuedu/ for more information about the texas a&m department of physics and astronomy visit http://physicstamuedu/ #
